TROUBLE SHOOTING
Some air tools have inbuilt regulators which can be used to control speed/torque performance, on
machines without inbuilt regulators this can be done by varying the pressure of your air supply
regulator.
MAINTENANCE:
Every day, before use, remove the tool from the air line, use an oil can and pour the equivalent of a
tablespoon of suitable oil into the machine (through the air intake). Operate at low speed to
ensure lubrication of all moving parts. If machine is in constant use or is to be used for long
periods of time a combination filter/lubricator must be fitted in the system. At all times the system
must be fitted with an air filter.
Recommended oils are Shell Tellus 22, Duckhams Zircon 32 or Castrol AWS32. Do not use
normal engine oil or similar.
Please note: failure to comply with the above Maintenance/Operating Instructions could
invalidate the Guarantee.
