AIR SUPPLY REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE
USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.
• Air compressors used with the grinder must comply with the appropriate
European Community safety directives.
• Use only clean, dry, regulated compressed air.
• A build up of moisture in the air compressor will accelerate wear and
corrosion in the grinder. Ensure any moisture is drained from the
compressor daily and the inlet filter is kept clean.
• If an unusually long air hose is required,(over 8 metres), line pressure may
need to be increased.
A typical airline
arrangement is shown
on the right. If an
automatic in-line filter/
regulator/lubricator
unit is used it will keep
the tool in good
condition but should
be regularly checked
and topped up with oil.
IMPORTANT: If a filter/lubricator unit is not used, the grinder should be
lubricated with 2 to 6 drops of oil, at least once a day or after 2 hours work,
depending upon the working environment. The oil can be inserted through
the airline connection point.
AIRLINE SAFETY
• Never exceed the maximum operating pressure for the grinder. A pressure
of 90psi with a flow of 4 cfm is required. Too high an air pressure will shorten
the life of the tool due to excessive wear.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
• Ensure the trigger is OFF before connection the tool to the air supply.
