To Check Safety Valve
If the safety valve
does not work
properly, over-pressurization may
occur, causing air tank rupture or
explosion and possible serious
injury.
1. Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. Ifthe valve is
stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
To Drain Air tank
1. Set the On/Auto/Off lever to
"OFF".
2. Close the globe valve.
3. Remove the air tool or
accessory.
4. Open the globe valve and allow
the air to slowly bleed from the
air tank until tank pressure is
approximately 20 psi.
5. Close the globe valve.
6. Drain water from air tank by
opening drain valve (counter-
clockwise) on bottom of air tank.
Water will
condense in the air
tank. If not drained, water will
corrode and weaken the air tank
causing a risk of air tank rupture
and possible serious injury.
7. After the water has been drained,
close the drain valve (clockwise).
The air compressor can now be
stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, then
reinstalled.
Oil
Drain air tank to
release air
pressure before removing the oil fill
cap or oil drain plug.
NOTE: Use air compressor oil such
as SAE-20 (API CG/CD) heavy duty
motor oil. Under extreme winter
conditions use SAE-10 weight oil. Oil
capacity is approximately 16 fluid
ounces.
Checking
1. Remove the oil fill plug (A). The
oil level should be even with the
top of the fill hole and no lower
than 6 threads from the top of fill
hole.
2. If needed, slowly add oil until it
reaches the top of fill hole.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and
drain oil into a suitable container.
3. Replace the oil drain plug (B) and
tighten securely.
4. Slowly add compressor oil until it
is even with the top of the oil fill
hole. NOTE: When filling the
crankcase, the oil flows very
slowly into the pump. If the oil is
added too quickly, it will overflow
and appear to be full.
5. Replace oil fill plug (A) and
tighten securely.
