residual current device (RCD).

Using an RCD reduces the risk of electric shock.

3. Personal safety

a) Stay alert, watch what you are doing and use

common sense when operating power tools.

Do not use power tools when you are tired

or under the inuence of drugs, alcohol or

medication.

A moment of inattention while working can result

in serious personal injury.

b) Wear personal protective equipment. Always

wear eye protection.

Protective equipment such as a face mask, non-

skid safety shoes, helmet or hearing protection

for situations where they are warranted will redu-

ce personal injury.

c) Prevent unintended starting. Make sure the

switch is in the OFF position before connec-

ting the power tool to the power source and/

or battery pack, picking it up or carrying it.

Carrying the power tool with your finger on the

switch or connecting it to the power source/bat-

tery pack when the switch is in the ON position

can result in accidents.

d) Remove any adjustment tools before starting

the power tool.

Leaving a spanner or key on or in a rotating part

on the power tool can result in personal injury.

e) Do not reach too far. Always stand with a rm

and balanced footing.

Doing so provides better control of the power

tool in unexpected situations.

f) Wear proper clothing. Do not wear loose or

baggy clothing or jewellery. Keep your hair,

clothing and gloves away from moving parts.

Loose clothing, jewellery or long hair can get

caught in moving parts.

g) If accessories for connecting dust extraction

devices are included, make sure that these

devices are connected and used correctly.

4. Operation and maintenance of power tools

a) Do not force the power tool. Use the proper

tools for the job you intend to do.

Using the proper tools makes for better and sa-

fer work at the intended speed.

b) Do not use the power tool if the power

switch cannot be turned ON or OFF.

Power tools that cannot be controlled with the

power switch are dangerous and must be repai-

red.

c) Disconnect the cord from the socket - and/or

the battery pack from the power tool - before

making any adjustments, changing access-

ories, or storing the power tool.

Such safety precautions reduce the risk of the

power tool starting unintentionally.

d) When not in use, store power tools out of

reach of children and do not let anyone use

1. GENERAL SAFETY INFORMATION

FOR POWER TOOLS

WARNING

Read all safety information and instructions.

Failure to follow the safety information and instructions

below may result in electric shock, fire and/or serious

injury.

Retain all safety information and instructions for

future reference.

Carefully follow the instructions in this manual and store

it in a convenient and accessible location. Retain this

manual for future reference until the machine is discar-

ded. If the machine is sold, the new owner must receive

this manual along with the machine.

Carefully follow the instructions below, keeping in mind

the intended use and the environments in which these

tools can be used.

1. Work area safety

a) Keep the work area clean and well lit.

Cluttered and/or dark work areas can cause ac-

cidents.

b) Do not use power tools in explosive atmosp-

heres, such as in the presence of ammable

liquids, gases or dust.

Power tools produce sparks that can ignite the

dust or fumes.

c) Keep children and uninvolved persons at a

safe distance while operating power tools.

Distractions can cause you to lose control of the

tool.

2. Electrical safety

a) The power tool plug must match the socket.

Never modify the plug. Do not use adaptor

plugs for earthed power tools.

Non-modified plugs and matching wall sockets

reduce the risk of electric shock.

b) Avoid physical contact with earthed surfa-

ces such as pipes, heating elements, ranges

and refrigerators.

There is an increased risk of electric shock if

your body is earthed.

c) Do not expose power tools to rain or moistu-

re.

The risk of electric shock increases if water gets

inside the power tool.

d) Do not use the cord inappropriately. Never

use the cord to carry or pull the tool or un-

plug the cord from the wall socket. Keep the

cord away from heat, oil, sharp edges and

moving parts.

Damaged or tangled cords increase the risk of

electric shock.

e) Use an extension cord that is suitable for

outdoor use when working with the power

tool outdoors.

Using an extension cord suitable for outdoor use

reduces the risk of electric shock.

f) If it is not possible to avoid using a power

English

the tool unless they are familiar with the tool

and these instructions.

Power tools are dangerous in the hands of

untrained users.

e) Maintain power tools. Check for misalign-

ment or binding of moving parts, breaka-

ge of parts and any other conditions that

could affect operation of the tool. If the tool

is damaged, have it repaired before using it.

Many accidents are caused by poorly maintai-

ned tools.

f) Keep cutting tools sharp and clean.

Properly maintained cutting tools with sharp cut-

ting edges do not bind and are easier to control.

g) Use the power tools, accessories and car-

bide inserts, etc. in accordance with these

instructions, taking into account the working

conditions and the work to be carried out.

Using the power tool for any purpose other than

its intended use may result in hazardous situ-

ations.

5. Operation and maintenance of battery-powered

tools

a) Only charge with chargers specied by the

manufacturer.

Chargers suitable for one battery type may pre-

sent a fire hazard when used with another bat-

tery type.

b) Use tools only with the specically designa-

ted battery.

Using another battery may present a risk of in-

jury or fire.

c) When the battery pack is not in use, store it

away from other metal objects such as clips,

coins, keys, nails, screws or other metal ob-

jects that could cause a short circuit from

one terminal to the other.

Short circuits of the battery terminals can cause

burns or fire.

d) Improper handling may result in liquid lea-

king from the battery; avoid contact. If con-

tact accidentally occurs, ush with water. If

the liquid comes into contact with the eyes,

seek medical advice.

Liquid leaking from the battery can cause irrita-

tion or burns.

6. Service

a) Have your power tool serviced by a qualied

service technician using only original spare

parts.

Doing so ensures that the power tool remains

safe and functions properly.

2. GENERAL SAFETY INFORMATION

FOR REBAR CUTTERS

1. Planned use and residual risks

The machine may only be used for cutting metal

objects, such as reinforcing mesh and rebar. The

maximum cutting diameter is 16 mm and the tensile

strength of the material (steel) must not exceed 490

N/mm². Do not use the machine to cut sheet metal

or any objects other than those mentioned above.

Any use other than those explicitly stated above are

not considered appropriate and therefore not per-

mitted.

Hikoki assumes no liability for improper use of the

machine and for any alterations or modifications

made to it.

Operators must follow the instructions in this manual

to minimise the risk of accidents or person injury.

In particular, they must remain alert when working

under conditions that may cause:

– Any burns from overheated metal parts;

– Damage or injury from incorrect placement or

inadequate lifting or movement;

– Damage or injury caused by splinters/fragments

from the workpiece.

People near the machine when the operator is wor-

king are exposed to the following risks:

– Flying debris (dangerous objects, etc.).

The mechanical vibrations transmitted to the hands

and arms present a risk to operators’ health and sa-

fety, with particular regard to vascular, osteoarthritic,

neurological and muscular diseases.

Employers are responsible for assessing the risk of

mechanical vibrations in accordance with Directive

2002/44/EC.

• Cutting sheet metal is strictly forbidden.

• Using the machine for purposes other than tho-

se specified in this installation and maintenance

manual is strictly forbidden.

• Operating the machine in areas subject to a risk

of explosion is forbidden.

2. Safety devices

The machine is equipped with a safety device that

prevents contact with the upper part of the tool as it

returns after cutting. This is a protective plastic cover

that is attached to the machine using 2 screws

(see figure 1).

Never tamper with the safety devices.

3. Always wear a helmet, safety shoes and other pro-

tective equipment when working.

4. Hydraulic oil is flammable and the following precau-

tions must be taken to avoid fire.

• Do not remove the oil plug during operation or

when the tool is hot.

• Only fill with hydraulic oil after the tool has coo-

led down sufficiently.

• When filling with hydraulic oil, choose a location

that is free of any nearby flammable substances

and avoid spills. If hydraulic oil is spilled, make

sure it is wiped up thoroughly.

• Do not smoke when replenishing the hydraulic

oil or using the tool.

• Do not use the tool near the location where the

hydraulic oil was filled.

English

5. Never place your fingers near the cutting blades

when the tool is in use. Personal injury may occur

6. Do not cut rebar to a length of less than 30 cm. Ne-

ver cut more than one piece of rebar at the same

time. Doing so presents a risk of flying fragments

which can cause accidents, damage, or injury.

7. Do not use damaged blades.Replace damaged bla-

des with new ones because they not only damage

the tool but also cause accidents.

8. Perform a test run before use. If there is any sign of

trouble during the test run, or any abnormal noise or

abnormal vibration, switch off the tool immediately,

stop using it and arrange for inspection or service

at an authorised service workshop. Continued use

may result in personal injury.

9. If you accidentally drop or bump the tool, make sure

it is not damaged, cracked or deformed. Damage or

injury may occur if this is the case.

CAUTION

1. Check the blades and housing for loose bolts

and screws, proper hydraulic oil level, etc. before

use. Also make sure that mounting tools such as

adjustable spanners are removed.

2. Be sure to remove the battery during inspection,

cleaning or blade replacement. Personal injury

may occur if the tool is switched on unintentionally.

3. Make sure that nobody is below you when wor-

king at height. Dropping tools or other materials

can result in accidents, injury or damage.

4. Use only recommended hydraulic oil.The hydrau-

lic oil must have an international ISO viscosity

grade of 46 (VG46).

5. If hydraulic oil comes into contact with eyes,

do not rub them. Flush them immediately and

thoroughly with clean running water and consult a

physician for treatment. If left untreated, hydraulic

oil can cause eye injury.

6. If hydraulic oil comes into contact with the skin,

wash immediately and thoroughly with clean wa-

ter and soap. Failure to do so may result in skin

inflammation.

7. If hydraulic oil is accidentally swallowed, do not

attempt to induce vomiting. Contact a doctor im-

mediately for treatment.

8. When the hydraulic oil is not in use, make sure

that the cap is firmly closed on the container and

store it in a dark location out of direct sunlight and

out of reach of children.

9. Do not store the hydraulic oil container near a

source of combustion such as heat, open flames

or sparks. This can lead to an explosion.

10. Make sure that the battery is properly installed. If it

is not properly fitted, the battery may come loose

and cause damage or injury.

11. Do not discard the battery with ordinary house-

hold waste or burn it.

12. Store the battery out of the reach of children.

13. Use the battery correctly and in accordance with

its specifications.

3. ADDITIONAL SAFETY

INFORMATION

1. If the switch does not return to its original position,

discontinue use immediately and arrange for repair

at an authorised service workshop.

2. When using the tool:

• Make sure that the rebar is perpendicular to the

blades.

• Press and hold the switch until the piston

reaches its end position.

• The piston does not move forward again until

it has fully returned to its innermost position.

The purpose of this is to ensure that the next oil

pressure cycle is not applied when the hydraulic

valve inside the tool is open.

3. Replace the blades at an early stage. Using a chip-

ped or deformed blade may result in personal injury

as a result of flying fragments.

4. Carefully follow the instructions in Chapter 14, Sec-

tion 3, when replacing blades.

5. Always make sure that both the tool and hydraulic

oil are at a low temperature when filling the hydraulic

oil. Removing the oil plug while the tool is hot can

cause hydraulic oil inside the tool to spray out and

result in accidents or personal injury. Carefully follow

the instructions in Chapter 14, Section 1, before re-

placing or filling the hydraulic oil.

Information on electrical charge of new batte-

ries, etc.

Because the internal chemical substance is not

activated in new batteries and batteries that have

not been used for extended periods, the electrical

charge may be low when used for the first and se-

cond times. This is a temporary phenomenon and

the normal charging time will be restored after the

battery has been recharged 2 or 3 times.

How to make batteries last longer.

a) Charge the batteries before they are complete-

ly out of power. When you notice that the tool’s

power is decreasing, stop using the tool and

recharge the battery. Continuing to use the tool

and discharging the electrical power can dama-

ge the battery and shorten its service life.

b) Avoid charging at high temperatures. Rechar-

geable batteries are hot immediately after use.

Charging batteries immediately after use will

degrade the internal chemical substance and

shorten their service life. Let the battery rest and

charge it after it has cooled down for a while.

CAUTION

• If the battery is charged when it is still hot after

being recently used or left out in direct sunlight,

the charge indicator light will light up for 0.3 se-

conds and then go out for 0.3 seconds. If this

occurs, allow the battery to cool down before you

begin charging.

• If the charge indicator light flickers (at 0.2-se-

cond intervals), check and remove all foreign

objects from the charger’s battery connector. If

no foreign objects are present, it is likely that the

battery or charger is faulty. Contact an authori-

sed service workshop.

• It takes about 3 seconds for the microcomputer

in the UC18YSL3 to detect that a charge has

been interrupted and the battery has been remo-

ved. For this reason, wait at least three seconds

before reinserting the battery in the charger for

continued charging. The battery may not rechar-

ge correctly if the battery is reinserted before

waiting three seconds.

12. CONDITIONS OF USE AND

SPECIFIC INSTRUCTIONS

This tool operates with oil pressure.

When used in cold conditions or in the winter, the vis-

cosity of the hydraulic oil will increase significantly and

diminish the operation of the tool. In cold conditions, the

tool should be warmed up before use.

Switch on the tool and let it run continuously for 30 to 60

seconds without cutting any rebar (unloaded operation).

WARNING

Do not place your hands near the piston while it is war-

ming up.

Depending on the environment and use conditions, the

hydraulic oil may become hot. This can lower the vis-

cosity of the hydraulic oil and reduce the tool’s cutting

performance. Allow the tool to cool down and then re-

sume operation.

IMPORTANT

When the oil temperature exceeds about 70 °C, switch

off the tool until the oil cools down.

The tool is not designed for continuous use so work

needs to be planned to allow for sufficient breaks

so the hydraulic oil can cool down to room tempe-

rature.

CONTACT THE MANUFACTURER FOR CONTI-

NUOUS AND PROLONGED OPERATION

• Check that the air inlets on the motor housing are

clear and the cooling surfaces are clean in order to

prevent the tool from becoming dangerously over-

heated.

• Do not modify the calibration of the safety devices

(maximum pressure valves).

• Do not service, clean or replace the blade or guard

while the tool is in operation and with the battery

connected.

• Check the condition of the power cord regularly. If

damaged, replace it with an original cord.

• Do not remove the protective devices installed on

the tool and accessories.

• The parts and components that have a safety func-

tion (insulation, protection, etc.) must not be repai-

red, but must instead be replaced with original spare

parts. If this is not the case, then the tool does not

comply with the regulations that are prescribed by

the standardisation body and passed on to the ma-

nufacturer.

• Always ensure that there are no traces of oil, grease

or corrosive substances on the equipment (especi-

ally the handle).

• Use a damp cloth and soapy water to clean plastic

components.

• Do not use gasoline or thinner to clean the tool.

• Store power tools in a dry place accessible only to

qualified personnel.

13. INITIAL AND ONGOING

2. Start-up

After installing the battery, press the ON/OFF switch

to start the machine.

3. Cutting

Place the blades perpendicular to the axis of the

workpiece.

The blades may break if the cutting thickness is gre-

ater than the limit for the tool.

After the blade is correctly positioned on the work-

piece, press and hold down the start button until

cutting is complete.

IMPORTANT Position the blades so that the cut-

ting edge is minimised.

Blade positions that are not perpendicular in re-

lation to the workpiece will increase the cutting

thickness.

4. Adjusting the cutting head

The cutting head of the machine can be freely adju-

sted (rotated 360°) to assist the operator in positio-

ning and subsequent cutting.

To adjust the head, turn the handle (item 1 in fig. 4),

as indicated by the arrows.

Adjusting the cutting head with the tool discon-

nected and not in operation. Hold the handle

(item 1 in g. 4) and turn (item 4 in g. 2) rmly

without pressing the ON/OFF switch and turn

the cutting head to the desired position.

5. Manual return valve

The manual return lever has two positions (se fig 5)

– Position 1: valve closed. The piston’s working

and return strokes are performed automati-

cally.

– Position 2: Valve open. To interrupt the work

stroke or in an emergency, move the lever

to position 2 to return the piston to its home

position.

IMPORTANT: If the machine is not working,

make sure that the manual return valve is in po-

sition 1.

14. MAINTENANCE AND INSPECTION

• All maintenance, inspection and cleaning opera-

tions must be carried out with the power supply

disconnected and when the machine is cool (see

person responsible for the maintenance plan).

• Maintenance work must be carried out in a suitable

location in accordance with applicable safety regu-

lations.

• Clean the machine thoroughly before starting main-

tenance work (see Section 12).

• Use appropriate personal protective equipment

when performing maintenance work.

AFTER THE MAINTENANCE WORK IS FINISHED,

MAKE SURE THAT ALL SAFETY DEVICES ARE

CORRECTLY REFITTED.

U=Operator; S=Service workshop.

In case of doubt about maintenance procedures, or-

dering spare parts or complicated maintenance work,

contact your authorised dealer.

1. Replacing and/or replenishing hydraulic oil

Changing the oil or refilling it must be done in such

a way that no particles/contaminants get into the oil

or the tank. Contamination in the oil can damage the

hydraulic parts irreversibly.

• MAKE SURE THAT THE OIL DOES NOT CON-

TAIN ANY CONTAMINANTS.

• DO NOT USE DIRTY TOOLS.

• DO NOT WORK IN A DIRTY ENVIRONMENT.

Changing the hydraulic oil:

USE A SUITABLE DISPENSER, PREPARE THE

CORRECT AMOUNT OF HYDRAULIC OIL (0.3 L).

LEAKING OIL CAN CAUSE SHORT-CIRCUITS,

FIRES OR EXPLOSIONS.

a) Position the machine horizontally in a stable po-

sition on a work surface with the magnet cover

facing upwards. Place a container under the

English

c) Drain the oil tank completely of hydraulic oil in a

suitable manner (use an oil suction pump) so no

oil can leak into the machine.

d) Slowly pour in the correct amount of oil (0.3

litres) with suitable equipment (such as a fun-

nel). Use only new or clean recommended oil

(as indicated on the following page). Try to avoid

introducing any air when filling the hydraulic oil.

e) Fill to the upper edge of the hole.

f) Refit the oil cover and tighten it slightly.

g) Run for a few strokes to ventilate the large air

bubbles.

h) Move the piston to its outermost position, start

and stop the motor several times (before the pis-

ton automatically returns).

i) Complete filling.

j) Fit the oil cover and tighten it.

See figure 6.

Filling hydraulic oil:

Before removing the magnetic cover to check the oil

level, make sure that the piston is in its outermost

position - pull it out if necessary. Failure to do so

may cause the hydraulic oil to leak, air bubbles to

form and/or the oil level to be measured incorrectly,

causing the machine to malfunction.

Proceed as follows, only after having carried out the

steps above:

a) Position the machine horizontally in a stable po-

sition on a work surface with the magnet cover

facing upwards. Place a container under the

machine to catch the oil.

b) Unscrew the magnetic cover (see item 6 in Sec-

tion 8) and remove any residue.

c) Check the amount of oil that is missing.

d) Slowly fill up to the top of the hole with the re-

commended new and clean oil using suitable

equipment (such as a funnel).

e) Fit the oil cover and tighten it.

Maximum oil volume:

0,3 l

Hydraulic oil type:

ESSO NUTO 46 or equivalent approved oil HLP46

according to the DIN 51 524 MIL-H 17672 C stan-

dard.

When discarding the machine or any of its parts (oil,

plastic, etc.), follow the applicable regulations in the

relevant country.

2. Checking screws

Check periodically - or daily if work is frequent or

prolonged - and make sure that all screws are pro-

perly tightened.

FAILURE TO TIGHTEN THE SCREWS MAY RE-

SULT IN SERIOUS INJURY.

3. Checking the blades

Damaged blades reduce the tool’s performance and

cause the electric motor to overheat.

Replace worn blades immediately.

See figure 7.

Replacing blades:

a) Loosen the 2 screws (B, fig. 7.2) and remove the

protective cover.

b) Loosen the 2 side screws (C, fig. 7.3) which se-

cure the spring in the movable blade.

c) Pull out the machine head pressure cam (D, fig.

7.4).

d) Remove the nut and washer (H, fig, 7.5) and pull

out the pin (E, fig 7.5).

e) Remove the upper part of the head (F, fig. 7.5).

f) Release the blades as shown in fig. 7.6.

g) If the blades are in good condition, rotate them

120°; otherwise replace them with new blades.

Clean the head and cutters before assembly.

h) Assemble the blades as shown in fig. 7.8: the

short blade in the upper part and the long blade

in the lower part.

Important: position the groove (J, fig. 7.8) as

shown in fig. 7.8. Use a copper or aluminium

hammer.

i) Be careful when assembling the machine head

pressure cam (I), to ensure it is placed in the

correct position (see fig. 7.7).

j) Tighten the nut and washer (H, fig 7.5). Make

sure that the upper part of the machine head

can move up and down without jamming.

k) Screw the two screws back onto the piston (C,

fig. 7.3) using thread adhesive.

l) Fit the protective cover.

4. Hydraulic components

1. Cleaning the piston

KEEP THE PISTON HEAD CLEAN TO PREVENT

INCOMPLETE RETURNS AT THE END OF THE

CYCLE, OTHERWISE A NEW CYCLE WILL NOT

START.

Proceed as follows in the event of malfunctions

caused by built-up dirt on the piston head (see fi-

gure 8):

• Place the machine horizontally on a stable work

surface.

• Remove the cover by loosening the two screws

on the sides.

• Put the piston B back in its innermost position

using a lever.

• Clean piston head A.

2. Adjusting the stroke of the upper moveable

blade

See figure 7.
