ELECTRIC IMPACT WRENCH

WARNING! Read all safety warnings and all instructions. Failure to follow the

warnings and instructions may result in electric shock, ﬁre and/or serious injury.

Safety instructions

1. General safety instructions for power tools

1). Job security

2). Electrical safety

3). Personal safety

Retain all safety notices and instructions for future use.

Warning! Read all safety warnings and instructions. Failure to follow the safety

instructions and instructions can result in electric shock, fire and / or serious injury.

The term “power tool” used in the safety instructions refers to mains-operated power tools

(with a power cord) and to battery-operated power tools (without a power cord).

a) Keep your work area clean and well-lit. Cluttered or unlit work areas can lead to

accidents.

b) Do not work with the power tool in an explosive environment in which there are

flammable liquids, gases or dust. Power tools generate sparks that can ignite the

dust or fumes.

c) Keep children and other people away while using the power tool. If you are

distracted, you can lose control of the device.

a) The power tool connector must match the socket. The plug must not be modified

in any way. Do not use adapter plugs with protective earthed power tools.

Unmodified plugs and matching sockets reduce the risk of electric shock.

b) Avoid body contact with earthed surfaces such as pipes, heaters, stoves and

refrigerators. There is an increased risk of electric shock if your body is grounded.

c) Keep power tools away from rain or moisture. Water getting into a power tool

increases the risk of electric shock.

d) Do not misuse the cable to carry the power tool, to hang it up or to pull the plug

from the socket. Keep the cord away from heat, oil, sharp edges, or moving parts of

the device. Damaged or tangled cables increase the risk of electric shock.

e) If you work with a power tool outdoors, only use extension cables that are also

suitable for outdoor use. Using an extension cord suitable for outdoor use will

reduce the risk of electric shock.

f) If operating the power tool in a damp environment cannot be avoided, use a residual

current circuit breaker. The use of a residual current circuit breaker reduces the risk

of an electric shock.

a) Be attentive, pay attention to what you are doing, and use your common sense

when working with a power tool. Do not use a power tool when you are tired or

under the influence of drugs, alcohol or medication. A moment of inattention while

using the power tool can result in serious injury.

b) Wear personal protective equipment and always protective goggles. Wearing

personal protective equipment, such as a dust mask, non-slip safety shoes, hard

hat or hearing protection, depending on the type and use of the power tool, reduces

the risk of injuries.

c) Avoid unintentional start-up. Make sure that the power tool is switched off before

you connect it to the power supply and / or the battery, pick it up or carry it.

Accidents can occur if you have your finger on the switch while carrying the power

tool or if you connect the device to the power supply when it is switched on.

d) Remove adjustment tools or wrenches before switching on the power tool. A tool or

wrench in a rotating part of the device can cause injuries.

e) Avoid abnormal posture. Make sure you have a secure stance and keep your

balance at all times. This gives you better control of the power tool in unexpected

situations.

f) Wear suitable clothing. Do not wear baggy clothes or jewelry. Keep your hair,

clothing and gloves away from moving parts. Loose clothing, jewelry or long hair

can be caught in moving parts.

g) If dust extraction and collection devices can be fitted, ensure that they are connect

ed and used correctly. Using a dust extractor can reduce dust hazards.

a) Do not overload the device. Use the power tool designed for your work. With the

right power tool, you can work better and more safely in the specified performance

range.

b) Do not use a power tool with a defective switch. A power tool that can no longer be

switched on or off is dangerous and must be repaired.

c) Pull the plug out of the socket and / or remove the battery before making device

settings, changing accessories or putting the device away. This precaution prevents

the power tool from starting accidentally.

d) Keep unused power tools out of the reach of children. Do not allow people to use

the device who are not familiar with it or who have not read these instructions.

Power tools are dangerous when used by inexperienced people.

e) Maintain power tools with care. Check whether moving parts are working properly

and not jamming, whether parts are broken or damaged in such a way that the

function of the power tool is impaired. Have damaged parts repaired before using

the device. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Carefully maintained cutting tools with sharp

cutting edges are less likely to jam and are easier to guide.

g) Use the power tool, accessories, tool bits etc. in accordance with these instruc

tions. Take into account the working conditions and the work to be performed. The

use of power tools for purposes other than those for which they are intended can

lead to dangerous situations.

4). Use and treatment of the power tool

5). Service

2. Residual Risks

Have your power tool repaired only by qualified specialists and only with original

spare parts. This ensures that the safety of the power tool is maintained.

Even if you operate this power tool properly, there are always residual risks. The

following dangers can arise in connection with the construction and design of this

power tool:

Warning! This power tool generates an electromagnetic field during operation.

This field can, under certain circumstances, affect active or passive medical

implants. To reduce the risk of serious or fatal injuries, we recommend people

with medical implants to consult their doctor and the manufacturer of the medical

implant before operating the machine!

Damage to health resulting from hand-arm vibrations if the power tool is used

over a long period of time or is not properly operated and maintained.

Device specific safety instructions

Technical data

• Hold the power tool by the insulated gripping surfaces when performing an

operation where the fastener may touch hidden wires or its own wire. Fasteners that

come in contact with a "live" wire can "electrify" exposed metal parts of the power

tool and cause an electric shock to the operator.

• Do not use the power tool with a damaged cord. Do not touch the damaged cable

and pull the power plug if the cable is damaged during work. Damaged cables

increase the risk of electric shock.

• Secure the workpiece. A workpiece held in place with clamping devices or a vice is

held more securely than with your hand.

• Wait until the power tool has come to a standstill before putting it down. The

accessory tool can get caught and lead to loss of control of the power tool.

The specified total vibration value and the specified noise emission values have been

measured according to a standardized test method and can be used to compare one

power tool with another. They can also be used for a preliminary assessment of

exposure.

Warning! Depending on how you use the power tool, the actual vibration values

may differ from those specified.

Take measures to protect yourself against vibration exposure. Try to keep the

exposure to vibrations and noise as low as possible. Examples of measures to

reduce vibration exposure are wearing gloves when using the tool, limiting

working hours and using accessories that are in good condition

Take into account the entire work process, including times when the power tool

is working without load or when it is switched off.

Suitable measures include regular maintenance and care of the power tool and

tool attachments, keeping your hands warm, regular breaks and good planning

of work processes.

Operation

Functionality

Overloading the motor is not possible because the striking mechanism disengages

when the rated load is reached.

Pay attention to the mains voltage! The voltage of the power source must match the

information on the rating plate of the power tool. Power tools marked with 230 V can

only be operated with 230 V.

With the direction of rotation switch you can change the direction of rotation of the

power tool. However, this is not possible when the on / off switch is pressed.

Press the direction switch to the right as far as it will go.

Push the direction switch to the left as far as it will go.

To start up, press and hold the on / off switch.

To switch off, release the on / off switch.

You can continuously regulate the speed of the switched-on power tool, depending on

how far you press the on / off switch.

Light pressure on the on / off switch results in a low speed. The speed increases with

increasing pressure.

You can also use the speed preselection dial to preselect the required speed during

operation.

Keep the air slots and the motor housing as free of dust and dirt as possible.

Maintenance

2. Left rotation:

Before starting any work on the power tool, pull the power plug out of the socket.

When inserting a socket, make sure that it is firmly seated on the tool holder. If the

socket is not firmly connected to the tool holder, it may loose again and can not work

properly.

Push the socket the square of the tool holder.

The tool holder with the tool is driven by an electric motor via a gearbox and hammer

mechanism.

The work process is divided into two phases: screwing and tightening (striking

mechanism in action).

The hammer mechanism kicks in as soon as the screw connection gets stuck and the

motor is loaded. The hammer mechanism converts the power of the motor into

uniform rotary impacts. When loosening screws or nuts, this process is reversed.

Wipe the device with a clean cloth or blow it out with compressed air at low pressure.

Excessive accumulation of metal dust can cause electricity to be conducted from the

internal parts to exposed metal parts!

If the power tool's power cord is damaged, it must be replaced with a specially

prepared power cord that is available from the customer service organization.

Only put the power tool on the nut / screw when it is switched off, otherwise the

rotating tool bits may slip off.

The torque depends on the duration of the impact. The maximum torque achieved

results from the sum of all individual torques achieved through impacts. The maximum

torque is reached after a stroke duration of 3-5 seconds. After this time, the tightening

torque only increases slightly. On the other hand, the gear housing may heat up

heavily.

Note: The consequences of excessive heating may cause high wear and tear on all

hammer mechanism parts and require high lubricant.

Screw connections with a hard, springy or soft seat

With a springy or soft seat, the maximum tightening torque is lower than with a hard

seat. A significantly longer impact time is also required.

Renewal of accessories

Worn or damaged accessories must be replaced immediately.

The following use cases result accordingly:

- A hard seat is provided for screw connections from metal to metal when using

washers. The maximum torque is reached after a relatively short impact time

(steep characteristic curve). Unnecessarily long striking times only damage the

machine.

- A Resilient fit is given for screw connections from metal to metal, but when using

spring washers, disc springs, studs or screws / nuts with a conical seat and when

using extensions.

- A soft fit is given for screwing of metal on wood, or use of lead or fiber washers

as a base.

If the torques achieved in a sequence of impacts are measured in the experiment and

transferred to a diagram, the curve of a torque curve is obtained. The height of the

curve corresponds to the maximum achievable torque, the steepness shows the time

in which this is achieved.

A torque curve depends on the following factors:

- Strength of the screws / nuts

- Type of base (washer, disc spring, seal)

- Strength of the material to be screwed

- Lubrication conditions on the screw connection

The impact duration must be determined for each required tightening torque. The

tightening torque actually achieved must always be checked with a torque wrench.
