Drain Tank
NOTE: Operation of the air compressor will cause condensation to build up in
the air tank. Always drain tank on a washable surface or in a suitable container
to prevent damaging or staining surfaces.
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.
Open Drain
Valve
6. Drain water from air tank by opening drain valve on bottom
of tank.
Risk of Bursting. 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.
7. After the water has been drained, close the drain valve. The
Closed Drain
Valve
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
NOTE: Use an oil specifically formulated for use in an air compressor, such as
Porter-Cable PAS1 air compressor oil. Oil may be found at the store where the
air compressor was purchased.
NOTE: Crankcase oil capacity is approximately 48 fluid ounces (1.4 L).
Checking
1. The oil level should be to the middle of the sight glass (C).
2. If needed remove oil fill plug (A) and slowly add oil until it reaches the
middle of the sight glass.
Changing
C
B
A 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. Sowly add compressor oil until
the oil level is in the middle of the
sightglass (C). 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.
Risk of Unsafe Opera-
tion. Overfilling with oil
will cause premature compressor failure. Do not overfill.
5. Replace oil fill plug (A) and tighten securely.
