Maintenance
WARNING: Always disconnect from the air supply and depressurise before
cleaning or carrying out any maintenance.
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear
quickly, and shorten the machine’s service life. Clean the body of your machine
with a soft brush, or dry cloth
IMPORTANT: There is very little that can go wrong with your air tool and it should
be noted that when an air tool fails to work it is generally because the internal
workings have corroded due to dirty, wet air and failure to follow the instructions
given below.
Daily maintenance procedure: Disconnect from the air supply, pour the
equivalent of a tablespoon of oil into the air intake. Operate the machine at low
speed to thoroughly lubricate all internal workings.
• If the machine is in constant use or used for long periods at a time, a combined
filter/lubricator must be fitted. There must be an air filter fitted at all times
• Use air tool oil. DO NOT UNDER ANY CIRCUMSTANCES USE NORMAL ENGINE OIL
• Failure to comply with the operating and maintenance instructions may
invalidate the guarantee
Storage
• Store this tool carefully in a secure, dry place out of the reach of children
