Failure to carry out maintenance tasks,
may invalidate the warranty on your
compressor.
In order to keep the compressor in good
working condition, regular maintenance is
essential.
WARNING
Service and maintenance must be
performed by an authorised agent. DO
NOT tamper with, or attempt to adjust
the pressure switch or safety valve.
Before moving or carrying out any
maintenance on the compressor make
sure that the ignition switch is OFF and
the air tank pressure has been vented
and the compressor has been allowed
to cool down for a period of time.
Operations to be carried out after the first
60 hours of use:
•
Check that all bolts and nuts are tight,
particularly those retaining the crank case
and cylinder head.
• Replace the lubricating oil.
Operations to be carried out daily:
•
Drain condensation by opening the
valve located under the tank.
Tank drain valve
• Check pump oil level.
• Check engine oil level.
• Check all guards and covers are
secure.
• Check for fuel and oil leaks.
• Check for unusual noises or vibrations.
Operations to be carried out weekly (or
more frequently in dusty environments):
• Remove and clean the air filter by blow-
ing through from the clean side with an air-
line at low pressure.
• Re-place the filter, cover and screw.
DO NOT operate the compressor
without an air filter as foreign bodies or
dust could damge the pump and will
invalidate the warranty.
• Clean the compressor. DO NOT use a
pressure washer or hose pipe to clean the
compressor as water could penetrate criti-
cal components and cause machine failure.
• Check that the relief valve vents pump
output and reduces engine speed when
maximum pressure is reached.
• Check that the compressor restarts
pressure build up automatically at 2 bar be-
low maximum pressure.
Operations to be carried out monthly:
• Check belt tension.
• A weight of 3 kg applied at the belt
mid-point should give a deflection of
approximately 10 mm.
• If adjustment is required, maintain the
alignment of the two pulleys. Adjust by
repositioning the engine using the screw
adjuster.
Operations to be carried out every 100 working hours:
• Change the air filter element.
• Replace the pump lubrication oil with an oil suitable for temperatures ranging from -5 °C
to 45°C, viscosity Type 68 compressor oil.
• Drain the oil when it is warm, not hot, as this will drain more effectively.
• Place a suitable container under the oil pan and remove the drain plug.
• Once all the oil has drained, replace the oil plug and refill with new oil to the correct
level.
• Replace the engine oil with semi-synthetic SAE15w40 engine oil.
• Check all tube fittings and electrical connections.
• Inspect the pressure tank inside and out for damage or corrosion.
