TROUBLESHOOTING

MAINTENANCE

If the air impact wrench fails to work effectively, perform the 

following checks:

•  Check the air inlet is free of any dirt or blockages.

•  Ensure the wrench is lubricated properly.

•  Check that the pressure on the air compressor is within its 

||

working range. If not, let the compressor rest to 

||

re-pressurise / refer to the compressor instruction manual. 

Note: This tool is rated at 90psi. Ensure your compressor is set no higher than 90psi.

•  Keep the ventilation vents of the wrench clean at all times, if 

possible, prevent foreign matter from entering the vents.
•  If the enclosure of the wrench requires cleaning, do not use 

solvents but a moist soft cloth only. Never let any liquid get inside 

the wrench; never immerse any part of the wrench into a liquid.
•  

Oil the wrench after each use.
