IMPACT WRENCH SAFETY INSTRUCTIONS

1. ALWAYS use the impact wrench in the manner and for the functions

described in these instructions.

2. ALWAYS ensure the machine is not moving with the switchbar in the centre

position when changing sockets etc. Use only Impact Wrench

sockets....DO NOT use standard sockets.

3. ALWAYS finish tightening wheel nuts or engine parts with a torque wrench

or suitable spanner to the correct torque as recommended by the vehicle

manufacturer.

4. ALWAYS 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 normally sufficient.

5. ALWAYS use outdoor extension leads if working outdoors. Always use an

approved cable extension suitable for the power rating of the battery

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

same size or larger than that on the charger. When using a cable reel,

always unwind the cable completely.

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.

The battery charger for this appliance is of double insulated design

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

wired up 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 the battery charger for 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 the fuse cover, 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

Do not use an extension longer than 10 metres and one where the

conductors, are less than 1.5mm2.

If used outdoors, ensure the extension cable is designed for outdoor use.

SAFETY SYMBOLS

The full technical specification of the battery charger is printed on a label on

the charger. The meanings of the markings and symbols are shown below.

FIG 1

BATTERY CHARGING

1. The new battery pack will require

charging before use.

2. Squeeze the battery release buttons on

either side of the battery pack and pull

gently down to disengage the battery

pack from the machine as in Fig 1.

3. Insert the battery pack into the battery

charger, as shown in Fig 2, noting that it

will only fit one way.

4. Plug the charger into a 230v (mains)

power supply and switch ON.

• The green POWER ON light will

illuminate to show the unit is

connected to the mains supply. The

RED charging light will illuminate and

charging will begin.

• If charging does not take place,

ensure all connections are clean

and free of grease etc.

• If the red charging light will not stay on for more than a few

moments, the battery pack is likely to be defective and it must be

replaced with a new one.

• When charging is complete (typically

after about 1/2 hour), the RED charging

light goes off. The battery pack can be

considered charged and be removed.

The charging time will be dependant

upon the initial state of the batteries.

When charging a new battery pack it

may initially not accept full charge. This is

common & does not indicate a fault. It

can be recharged fully after it has been

discharged a couple of times.

5. After charging, switch off and unplug the

charger from the power supply.

6. Remove the battery pack from the

charger and slide it back into the machine

until it clips into place.

FIG 1

FIG 2

The battery pack should slide in easily.If the battery pack is not to be fitted

immediately, ensure that the metal contacts are protected so as to avoid

the possibility of a short circuit which would cause damage.

Remember to avoid extremes of heat or cold when charging. Avoid temperatures

outside the range of Minimum 4°C /Maximum 50°C. Avoid placing batteries in

direct strong sunlight or other heat source.

NOTE:

Ni-Cad batteries as used in Clarke cordless power tools should be given a

full charge when first supplied new. Maximum battery performance will be

achieved after approximately 5 complete charge/discharge cycles.

The battery should be fully discharged before recharging in order to achieve its

optimum performance.

Constant topping up after only a small amount of charge

has been used will, in effect, reduce its capacity.

Nickel cadmium batteries will slowly lose their power whilst in storage. If they become

fully discharged, do not leave the batteries in this state for any length of time.

OPERATION

CAUTION: ALWAYS BE SURE THAT THE TOOL IS SWITCHED OFF BEFORE

ATTACHING OR REMOVING A SOCKET. ALWAYS TAKE CARE TO USE THE

CORRECT SIZE SOCKET FOR BOLTS AND NUTS. AN INCORRECT SOCKET

WILL CAUSE DAMAGE TO THE BOLT OR NUT.

1. Align the chosen socket and simply push it onto the anvil. Use only ½”

square drive impact sockets as listed on page 14.

2. Squeeze the trigger to start the machine. Release the trigger to stop.

3. To run the impact wrench in reverse, push the

switch-bar through the drive unit as shown in Fig

3. The direction of rotation is shown on the end

face of the switch-bar.

• The 3-position switch bar controls forward or

reverse direction of rotation. Select the

appropriate position ONLY when the machine is

STATIONARY. Do not move the switch-bar when

the spindle is moving. When the switch-bar is in

the central position the trigger is locked.

4. Always check the direction of rotation before

operation.

5. Turn off the machine as soon as the impact

sound is heard.

FIG 3

Note: As the battery becomes discharged, the power available will drop.

Operating the machine at low speed will cause a reduction in torque.

6. After use, recharge the battery pack as shown on pages 8-9. Avoid leaving

your batteries in a discharged state.

LOOSENING A WHEEL NUT

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

placing firmly on the square drive of the wrench.

2. With the FORWARD/NEUTRAL/REVERSE switchbar

in the REVERSE running position, and holding the wrench firmly in BOTH

HANDS, pull the trigger. The nut will be impacted repeatedly until it is

loosened. IMPORTANT! Release the trigger immediately the nut begins to

loosen.

3. 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-bar in the clockwise

(FORWARD) running position, and holding the wrench firmly in BOTH

HANDS, pull the trigger.

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