Clarke CIR450 Istruzioni per il funzionamento e la manutenzione

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.
