Manufactured and tested in accordance with to ISO 6789 Standards.

Whilst every effort has been made to ensure that the accuracy of information given in this manual is correct at time of going to print, the Draper Tools policy of continuous improvement determines the right to change specification without notice.

This torque wrench is accurate to ± 4% of the set load and has been manufactured and tested in accordance to ISO 6789. Torque tools are classified as test devices. If a calibration routine is required, the calibration interval shall be chosen on the basis of the factors of operation such as required accuracy, frequency of use, typical load during operation as well as ambient conditions during operation and storage conditions. The interval should be decided according to the user's procedures for the control of test devices and by the requirements of the user. If the user does not use a control procedure, a period of use of 12 months, or approximately 5000 cycles can be taken as a default value of the recalibration interval. For the first recalibration,

the period of validity starts with user's first operation of the torque tool.

In addition to these specifications, factory or legal regulations shall be observed. The torque tool shall be recalibrated when it has been subjected to an overload greater than 125% of maximum rated load and after repair, or after any improper handling which might influence any errors in measurement.

4.3 HANDLING & STORAGE

Ensure you have a good stable position whilst using this product. Care should be exercised when using this product due to rotating parts etc. Store the product together with this manual in its protective case in a cool dry place with the torque wrench set to its minimum setting. This product should be cleaned, maintained and lubricated regularly to ensure it is operating at peak performance.

5. HEALTH & SAFETY INFORMATION

WARNING! Never use the torque wrench to undo bolts, nuts or fasteners, as this will damage the calibrated setting

Always adjust the torque wrench upwards through the scale to reach the required torque. Calibration will be affected if the torque required is set by coming down the scale. IMPORTANT: Only pull the torque wrench in the direction of the arrow shown on the top

face of the torque wrench. Incorrect application of force in the wrong direction will permanently and irrevocably

damage the torque wrench. Incorrect use of the torque wrench is this manner invalidates the warranty.

Always refer to manufacturer's literature, workshop manual, Autodata or Haynes manual for recommended TORQUE SETTINGS and if applicable the sequence for tightening and final torquing of fasteners.

If critical torque measurement is required, it is recommended the torque wrench is independently calibrated before first use and that the user puts in place a re-calibration schedule appropriate for the application.

7. UNPACKING & CHECKING

7.1 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).

8. OPERATING INSTRUCTIONS

8.1 OPERATION INSTRUCTIONS - FIG. 1

IMPORTANT:

Always use the correct size socket. Apply a steady pull to the handle of the torque wrench. When the required 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, adjust to the lowest torque setting for storage. Do not turn adjustment below lowest torque setting. Never use the torque wrench to undo nuts, bolts or fasteners. This will result in the

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.

8. OPERATING INSTRUCTIONS

First select required torque scale, then pull-out torque setting handle , lock into the spindle at 90 degrees and turn until handle edge is at the required torque value.

FIG.1

*83317 shown

NOTE: To obtain correct torque setting ONLY move the handle UPWARDS through the range. DO NOT set the torque required by moving down through the range as this will NOT give the correct torque setting.

8. OPERATING INSTRUCTIONS

Push the drive square  through the head - checking the direction arrow  of the torque wrench is correct for a left or right handed thread.

FIG.4

FIG.4.1

NOTE: Items 72623 and 72714 have a double sided, dual drive adaptor. To change drive size, simply push out the drive square and re-insert to get the correct rotation for torque application.

IMPORTANT: Only pull in the direction of the arrow - incorrect application of force will irrevocably damage the torque wrench mechanism.

FIG.5

8. OPERATING INSTRUCTIONS

When the correct torque level has been reached stop pulling!

If you continue to apply torque after you can hear, feel and see the torque wrench “CLICK” you will damage your fixings. DO NOT apply torque again to “test’ if the torque has been applied as this may damage the fixing.

After use ALWAYS rest the torque wrench to its lowest setting, clean with a soft dry cloth and return the torque wrench to its storage case for protection.
