OPERATING INSTRUCTIONS & MAINTENANCE
If you restart the compressor and the overload
cutout activates again, switch off the
compressor, remove the plug from the mains
and have your compressor checked by a
qualified service agent.
Draining the Reservoir
Caution!
It is important to drain the reservoir
before storage.
Switch the air compressor off, by pressing down
the red On/Off button, and remove the plug from
the mains supply.
Place a suitable container beneath the
compressor to catch any condensation.
Carefully undo the drain valve anti-clockwise
until you hear a hissing noise, this is the
reservoir depressurising (Fig 17).
When the gauge indicates zero and the hissing
has stopped, tighten the drain outlet nut again.
Oil Changing
For changing the pump oil, be sure to do the
following:
1. Turn the unit off and unplug the power cord
from the receptacle.
2. Allow the compressor time to cool if it has
been in operation.
3. Open the drain valve to bleed all air from the
tank.
4. Close the drain valve.
5. Remove the oil fill cap on the pump.
6. Remove the sight glass with a box end
wrench or socket. Drain the oil into a suitable
container and dispose of properly. The
compressor may need to be tipped slightly
towards the drain hole to allow all of the oil
to drain.
7. Reattach the sight glass. When
re-assembling. Be sure the gasket is between
the sight glass and the pump crankcase.
8. Refill the compressor pump with an air
compressor oil such as SAE-30 non-
detergent (API CG/CD Heavy Duty) oil at
slow intervals until the oil reaches the center
of the red circle in the sight glass. Use a
SAE-10 during extreme winter conditions.
Maintenance
Important:
Before carrying out any
maintenance, always disconnect the
compressor from the mains supply, drain the air
receiver and, if necessary, allow the machine to
cool down before starting work.
1.The compressor must be drained completely
by loosening the water drain cock. Drain the air
receiver tank daily after use.
2. The air filter can be removed for either
cleaning or replacing. Clean the air filter element
after every 100 hours of use or if low pressure is
experienced. Replace the air filter after 200
hours of use. Note: Under no circumstances
should the compressor be operated with the air
filter removed.
3.Cleaning and maintaining the compressor
regularly will give a long and trouble free life.
Before long term storage it is advisable to give
the compressor a thorough clean. This should
include the removal of all fitted accessories. Do
not use any solvents as these can damage
plastic parts. Only use a clean cloth dampened
with warm soapy water. Any metal parts should
be given a wipe with a light machine oil to
prevent rusting.
Caution.
Water must never come into contact
with the compressor.
