6.1 PACKAGING

Carefully remove the Torque wrench from the packaging and examine it for any sign of damage that may have happened during shipping. If it is damaged; please contact the Draper Helpline (the telephone number appears on the title page).

Warning! Some of the packaging materials used may be harmful to children. Do not leave any of these materials in the reach of children.

7. OPERATION AND USE

7.1 OPERATION INSTRUCTIONS

IMPORTANT: Always use the correct size socket and if necessary, accessory. Apply a steady pull to the handle of the torque wrench. When the applied torque is reached, this will be indicated by the following:

1. Audible click:
   NOTE: The click will be quieter at lower torque settings.

2. Touch:
   The handle will be felt to “break away” at the point of the set torque.
   WARNING At low torque levels the “break away” will be very soft. Check on a non-critical fastener before use so that you can familiarise yourself with this.

3. Visually:
   The handle will be seen to “break away” at the point of the set torque.
   WARNING At low torque levels the “break away” will be very soft. Check on a non-critical fastener before use so that you can familiarise yourself with this.

WARNING:
Never continue to pull on the torque wrench once the set torque is reached, as this will result in an incorrect torque being applied and possible damage to parts.

If the torque wrench has not been used i.e. new or has been in storage for some time, operate it several times at a low torque setting, which allows the internal lubrication to recoat working parts.

When the torque wrench is not in use, ensure adjustment at the lowest torque setting.

Do not turn adjustment below lowest torque setting.

Never use the torque wrench to undo nuts, bolts or fasteners. This will result in the ratchet mechanism being damaged.

The tool is rugged and designed for general use, but it is also a precision measuring instrument and should be treated as such.

Clean wrench by wiping. Do not immerse in any type of cleaner which will affect the internal lubrication.

Under no circumstances should any attempt be made to adjust or repair the torque wrench. A full repair and calibration service is available on request. A charge will be made accordingly.

It is recommended that a re-calibration schedule is put in place by the user to ensure the torque wrench is performing within its design criteria.

NOTE: Always set by turning the handle in the clockwise direction.

1. To unlock handle, turn locking screw anti-clockwise (4).

3. Continue to turn the handle for any additional increments to obtain the final setting (2.2).
4. Lock handle, turn locking screw clockwise (4).
