Thank you for purchasing this CLARKE Torque Wrench.

This torque wrench is designed to tighten nuts with precision. It should NOT be used for UNDOING nuts, as severe damage

could occur. With correct use, this tool will produce an accuracy of plus or minus 4%. You can hear and feel when the

desired torque setting has been reached. With careful and considerate use, the wrench will give years of reliable service.

OPERATION

A. Torque Setting Adjustment

The main body is marked in both Inch Pounds (in lbs), and Metre Kilograms (Mkg).

The barrel is marked with 20 graduations, one graduation = 12 in lbs or 0.14 Mkg.

Example: To set the torque to 492 in lbs

Ensure the lock nut is loosened, by turning it anti-clockwise. Turn the knurled handle until one of the

the zero marks on the chamfered scale is exactly in line with the next lowest graduation on the linear

scale on the main body - in this case it would be 480. (only one of the zero marks will line up correctly)

As the desired setting is higher than 480, continue to turn the knurled handle, one more graduations.

(one graduation equals12 in lbs). Therefore 480+12=492 in lbs

Finally, tighten lock nut to secure the setting.

B. Method of Use

Note: Preferably, DO NOT use knuckle or universal joints, as these could result in incorrect torque settings.

Place the square drive on to the socket or extension bar, perpendicular to the nut/bolt to be tightened.

Gripping the knurled handle with the right hand, whilst steadying the 3/8" square drive end with the

left, gently but firmly, pull the handle (i.e. in a clockwise direction) until a click is heard, and a slight

'break' in the handle is felt. IMPORTANT! DO NOT turn any further.

1. Do not jerk the torque wrench in any way to tighten a nut. Apply even pressure throughout the operation.

2. Release the wrench immmediately the click is heard/felt.

3. It should be noted that the 'click' becomes weaker with the lower torque settings.
