GENERAL SAFETY RULES

1) WORK AREA

1. Keep the work area clean and well lit. Cluttered and dark areas invite

accidents.

2. Do not operate power tools in explosive atmospheres such as in the

presence of flammable liquids, gasses or dust. Power tools create sparks

which may ignite dust or fumes.

3. Keep children and bystanders away while operating a power tool. Distrac-

tions can cause you to loose control.

2) ELECTRICAL SAFETY

1. Power tools must match the power outlet. Never modify the plug in any

way. Do not use adaptor plugs with earthed (grounded) power tools.

Correct plugs and outlets will reduce the risk of electric shock.

2. Do not expose power tools to rain or wet conditions. Any water entering

power tools will increase the risk of electric shock.

3. Do not abuse the electrical cable. Never use the cord for pulling or un-

plugging the power tool. Keep the cable away from sources of heat, oil,

sharp edges or moving parts. Damaged or tangled cables increase the

risk of electric shock.

4. When operating a power tool outdoors, use an extension cable suitable

for outdoor use. Using the correct cable reduces the risk of electric shock.

3) PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when you

are operating a power tool. Do not operate a power tool when you are

tired, ill or under the influence of alcohol, drugs or medication.

2. Wear personal protective equipment including eye protection. Safety

equipment such as a dust mask, non-skid shoes or hearing protection used

for appropriate conditions will reduce injuries. Use a face or dust mask if

operation is particularly dusty. Wear ear protectors/defenders as the noise

level of this machine can exceed 85dB (A).

3. Do not over-reach. Keep your proper footing and balance at all times. This

enables better control of the power tool in unexpected situations.

4. Avoid accidental starting of the machine. Ensure the switch is in the off

position and the locking button disengaged before plugging the machine

in to the power supply. Carrying power tools around with your finger on

the trigger or plugging in power tools that are switched on invites acci-

dents.

5. Remove any adjusting key or wrench before turning the power tool on. A

tool left attached to a moving part may result in injury.

6. Dress properly. Do not wear loose clothing or jewellery which may get

caught in moving parts. Wear protective hair covering to contain long

hair. For best footing, wear rubber soled footwear. Keep floor clear of oil,

scrap wood, etc.

7 Concentrate on the job in hand, no matter how trivial it may seem. Be

aware that accidents are caused by carelessness due to familiarity.

8. Switch the machine OFF immediately after the task is completed.

4) POWER TOOL USE AND CARE

1. Do not force the machine. Use the correct power tool for your application.

It will do a better and safer job at the rate for which it was designed.

2. Do not use the power tool if the switch does not turn it on and off. Any

power tool that cannot be controlled with the switch is dangerous and

must be repaired.

3. Disconnect the power tool from the power supply before making any

adjustments, changing accessories, or storing the tool. These measures will

reduce the risk of the power tool starting accidently.

4. Store power tools out of the reach of children and do not allow persons

unfamiliar with these instructions to operate the power tool. Power tools

are potentially dangerous in the hands of untrained users.

5. Maintain power tools in top condition. Keep tools/ machines clean for the

best and safest performance. Check for misalignment or binding of

moving parts, broken parts, or any condition that may affect the power

tool’s operation. If damaged, have the power tool repaired before use.

Many accidents are caused by poorly maintained power tools.

6. Use recommended accessories. The use of improper accessories could be

hazardous.

7. Machine cleanliness. Do not allow the ventilation slots in the machine to

become blocked with dust.

8. Check the power tool for damage before using the machine. Any dam-

aged part should be inspected to ensure that it will operate properly and

perform its intended function. Check for alignment of moving parts,

breakage of parts, mountings, and any other condition that may affect

the machine’s operation. Any damage should be properly repaired or

the part replaced. If in doubt, DO NOT use the machine. Consult your

local dealer.

5) SERVICE

1. When necessary, have your power tools serviced or repaired by a quali-

fied person using identical replacement parts. This will ensure that the

safety of the power tool is maintained.

IMPACT WRENCH SAFETY INSTRUCTIONS

1. Use the wrench correctly. Only use the impact wrench in the manner and

for the functions described in these instructions.

2. Changing Sockets. Always disconnect the machine from the power

supply when changing sockets etc. Use only Impact Wrench sockets....DO

NOT use standard sockets.

3. Achieve the correct torque. Always finish tightening wheel nuts with a

torque wrench or suitable spanner to the wheel-nut torque as recom-

mended by the vehicle manufacturer.

4. Avoid excessive use of the wrench. When tightening a nut or bolt, never

allow the wrench to impact more than 8 times - to avoid over tightening -

3 to 4 impacts is sufficient.

5. Care of the mains cable. Keep the mains cable well away from the

machine and ensure an adequate electrical supply is close at hand so

that the operation is not restricted by the length of the cable.

6. Use outdoor extension leads. If working outdoors, always use an approved

cable extension suitable for the power rating of this tool (see specifica-

tions), the conductor size should also be at least the same size as that on

the machine, or larger. When using a cable reel, always unwind the cable

completely.

Additionally, please keep these instructions in a safe place for future reference.

ELECTRICAL CONNECTIONS

This product is provided with a 13 amp, 230 volt (50Hz), BS 1363 plug, for

connection to a standard, domestic electrical supply. Should the plug need

changing at any time, ensure that a plug of identical specification is used.

WARNING: THIS APPLIANCE IS OF DOUBLE INSULATED DESIGN

No earth conductor is provided. The two wires in the mains lead should be

wired in accordance with the following colour code:

Blue — Neutral

Brown — Live

Connect the BROWN coloured cord to the plug terminal marked a letter “L”

Connect the BLUE coloured cord to the plug terminal marked a letter “N”

If this appliance is fitted with a plug which is moulded on to the electric cable

(i.e. non-rewireable) please note:

1. The plug must be thrown away if it is cut from the electric cable. There is a

danger of electric shock if it is subsequently inserted into a socket outlet.

2. Never use the plug without the fuse cover fitted.

3. Should you wish to replace a detachable fuse carrier, ensure that the

correct replacement is used (as indicated by marking or colour code).

4. Replacement fuse covers can be obtained from your local Clarke dealer

or most electrical stockists.

FUSE RATING

The fuse in the plug must be replaced with one of the same rating and this

replacement must be ASTA approved to BS1362.

If in any doubt, consult a qualified electrician. DO NOT attempt any electrical

repairs yourself.

CABLE EXTENSION

Always use an approved cable extension suitable for the power rating of this

tool (see specifications), the conductor size should also be at least the same

size as that on the machine, or larger. When using a cable reel, always

unwind the cable completely.

OPERATING INSTRUCTIONS

ALWAYS ENSURE THAT THE MACHINE IS DISCONNECTED FROM THE

POWER SUPPLY BEFORE CHANGING THE SOCKET.

LOOSENING A NUT

1. Remove any wheel trim, before selecting the appropriate socket and

placing firmly on the square drive of the wrench.

2. Select the appropriate socket and place firmly on the square drive of the

wrench. Holding the wrench firmly in BOTH HANDS, pull the rocker switch

at ‘L’ marked on the casing. The torque will build up and impact the nut

repeatedly until the nut is loosened.

3. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE position, and

holding the wrench firmly in BOTH HANDS, pull the trigger fully. The nut will

be impacted repeatedly until it is loosened. IMPORTANT! Release the

trigger immediately the nut begins to loosen.

4. Jack up the vehicle according to the vehicles handbook so that the

wheel is clear of the ground, then proceed to fully undo the wheel nuts..

ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE NUTS ON

YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE IS LIKELY TO

DAMAGE THE HEADS OF THE BOLTS/NUTS.

TIGHTENING A NUT

1 Start the nut by hand, ensuring it is not cross threaded, then with the

appropriate socket installed on the wrench, place it on the nut.

2. With the FORWARD/NEUTRAL/REVERSE switch in the FORWARD position,

and holding the wrench firmly in BOTH HANDS, pull the trigger gently. You

can vary the spindle speed by modulating finger pressure on the trigger.

3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten - do not

fully depress the trigger. When all nuts are nipped up, tighten progressively

by pulling the trigger fully and allowing the action to operate for 3 to 4

impacts only to prevent overtightening.

4. ALWAYS finish tightening with a torque wrench or suitable spanner. The

weight of the vehicle will need to be placed on the wheel to prevent it

from rotating while the nuts are tightened. Ensure the final torque applied

to the nuts meets the vehicle manufacturers recommendations.

MAINTENANCE

CLEANING

• Always inspect the tool before use, and ensure it is in top condition.

• Ensure all air vents are clear, (use compressed air to clean the

machine if possible).

GENERAL MAINTENANCE

• Ensure all nuts, bolts and screws remain tight to ensure the machine

is in safe working condition.

• Refer to your CLARKE dealer if internal maintenance is required.

• Check the power cable to ensure it is sound and free from cracks,

bare wires etc. avoid using solvents when cleaning plastic parts,

most plastics are susceptible to damage from the various types of

commercial solvents.

• All bearings etc, in this tool are lubricated with a sufficient amount

of high grade lubricant for the tools lifetime under normal operat-

ing conditions, therefore no further lubrication is required.

REPLACING THE CARBON BRUSHES

Remove and inspect the carbon

brushes after periods of extended use.

Replace them when they eventually

wear down. The brushes should be kept

clean and free to slide up and down in

the holders. Both brushes should be

replaced at the same time as a pair.

Only use identical brushes from your

Clarke dealer.

Use a screwdriver to remove the brush

holder covers from the machine body.

Draw out the worn brushes and insert

new ones before replacing the brush

holder caps.
