Safety
• Always release the spring tension after use by setting the torque
wrench to its lowest torque setting.
• Never use the torque wrench to undo nuts, bolts or other fasteners
– exceeding the maximum torque limit whilst loosening a fastener
could damage the wrench and affect its accuracy for future use.
• Never continue tightening once the desired torque setting has
been reached.
• Never set the torque wrench to a setting higher or lower than
the working torque range of the wrench (40–220 Nm).
• The torque wrench should be treated as a precision instrument.
Handle it carefully and store it in a clean, dry place where there is
no risk of it sustaining damage.

Instructions for use
• Always refer to the manufacturer's recommended torque settings
and tightening sequences.
• Make sure that the threading on the fastener to be tightened is free
from dirt and other contaminates.
• Tighten the fastener in a smooth and continuous motion until
a click is heard and felt. At low torque settings, the click can be felt
less noticeably than at high torque settings. Test using the wrench
on both low and high torque settings to familiarise yourself with
the feel of the different clicks.
Example: Setting a torque of 125 Nm
