3. NotesonUse
Important: Read this section in full BEFORE attempting to use this tool.
Failure to follow these instructions may result in damage to the tool or cause it to
require recalibration.
Important: ALWAYS read the manufacturer’s instructions for the recommended
torque settings. Incorrect torque settings can result in serious damage or injury
when the workpiece is used.
• Before rst use, or after extended periods of disuse, ensure that the torque
wrench is correctly lubricated:
− Set the micrometer to its maximum torque settings and then slowly reduce
it to its minimum setting.
− Operate the wrench several times at a low torque setting.
• Before rst use, test the torque wrench on non-critical xings to familiarise
yourself with the responses that indicate the congured torque is reached.
Important: Some responses may be less noticeable at lower torques.
• ALWAYS select the correct size and type of socket for use with the fastening.
• NEVER set the micrometer beyond its maximum or minimum settings as this
may damage the internal spring and distort the calibration.
• ALWAYS return the torque wrenches to their minimum settings when not
in use.
− Failure to do this will weaken the internal spring and distort the calibration
of the tool.
− Damage caused to the tool in this way is not covered by your warranty.
• Observe all standard safety precautions and good practices when in a
workshop environment.
• Inspect the product before every use for cracked, corroded or broken parts.
WARNING! DO NOT use this product if it is damaged in any way.
Contact Draper Tools for repair and replacement options.
• Use this product only for its intended purpose and do not modify it in any way.
Reaching the Set Torque
The torque wrench exhibits the following responses when the correct torque has
been reached:
• Audible: The tool will “click”.
• Tangible: The handle will “break away” from the xing.
• Visible: The handle will be seen to “break away” from the xing.
Important: These responses may be less perceptible at lower torques.
CAUTION! Once this has occurred, DO NOT continue to rotate the
torque wrench as this will deliver an incorrect torque and may damage
thexing.
