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.

The barrel is marked with 13 graduations, one graduation = 1N/m or 0.14 Mkg. Example: To set the torque to 90N/m 1. Ensure the lock nut is lo osened, by turning it anti-clockwise. Turn the knurled handle until the zero mark on the vertical scale is in line with the 84 mark on the horizontal scale. 2. Continue to turn the knurled handle unt il the 6 mark is in line with the centre line. 3. Tighten the lock nut to secure the setting.

Place the square drive on to the sock et or extension bar, perpendicular to the nut/bolt to be tightened. 2. Gripping the knurled handle with th e right hand, whilst steadying the 1/2” 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. DO NOT turn any further. Apply even pressure throughout the operation. DO NOT jerk the torque wrench when tightening a nut or bolt. This is a precise measuring instrument and should be treated as such. Release the wrench immediately the click is heard/felt. Note that the ‘click’ becomes weaker with the lower torque settings. CARE & MAINTENANCE Each torque wrench has been lubricated before leaving the factory. If the wrench has not been used for some time, operate it several times allowing the lubricant to re-coat the internal working parts. After use, keep adjustment at lowest torque setting. DO NOT turn handle below lowest torque setting. Clean wrench by wiping. Never im merse in any type of cleaning fluid. The wrench may occasionally requir e servicing/recalibration in order to ensure accurate readings, in which case, contact your CLARKE dealer.
