warning! do not use the torque wrench if damaged or thought to be faulty.
Ensure all workshop safety rules, regulations and conditions are complied with when using the torque wrench.
Maintain correct balance and footing. Ensure the floor is not slippery and wear non-slip shoes.
Keep children and unauthorised persons away from the working area.
Avoid over-torquing the wrench (110% of maximum torque range) as this will cause loss of accuracy.
Keep the wrench away from magnets.
In operation when you hear the continuous tone, stop pulling immediately especially in case the target torque/ angle is low.
Ensure all sockets, extensions and drivers are rated correctly and are of flawless construction. Avoid using adaptors and extensions for
best accuracy.
do not use the torque wrench if the batteries are low, torque accuracy will be affected.
do not use the wrench as a hammer or similar.
do not use on live electrical circuits the plastic handle is not insulated.
