Oil

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. 

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.

Changing

Drain tank to release
air pressure before

removing the oil fill cap or oil drain
plug.

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 reaches the middle of the sight glass (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. 

NOTE:

Crankcase oil capacity is approximately 29 fluid ounces (857,6 ml).

Overfilling with oil will cause premature compressor
failure. Do not overfill.

5.

Replace oil fill plug (A) and tighten securely.

To 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 into 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.

6.

Drain water from air tank by opening drain valve (counter-clockwise) on
bottom of 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.

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.
