CAUTION
To ensure ef
fi
cient operation and longer life of
the air compressor unit, a routine maintenance
schedule should be followed. The following
schedule is geared toward a consumer whose
compressor is used in a normal working environ-
ment on a daily basis. If necessary, the schedule
should be modi
fi
ed to suit the conditions under
which your compressor is used. The modi
fi
ca-
tions will depend upon the hours of operation
and the working environment. Air compressors
used in an extremely dirty and/or hostile envi-
ronment will require a greater frequency of all
maintenance checks.
WARNING
The air compressor should be turned off and
unplugged from the power source before any
maintenance is performed as well as the air
bled from the tank and the unit allowed time to
cool. Personal injuries could occur from moving
parts, electrical sources, compressed air or hot
surfaces.
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
fi
ll 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. Note: Torque the sight
glass 10-12 inch lbs. when re-assembling. Be
sure the gasket is between the sight glass and
the pump crankcase.
8. Re
fi
ll 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.
Oil Changing
For changing the pump oil, be sure to do the following:
