TO DRAIN TANK
Risk of unsafe operation. Air tanks contain high pressure air.
Keep face and other body parts away from outlet of drain. Use eye protection
[ANSI Z87.1 (CAN/CSA Z94.3)] when draining as debris can be kicked up into
face.
Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air
flow noise is loud when draining.
NOTE: All compressed air systems generate condensate that accumulates in
any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains
lubricating oil and/or substances which may be regulated and must be disposed of in
accordance with local, state, and federal laws and regulations.
1. Set the Auto/Off lever to "Off" and unplug unit.
2. Pull the regulator knob out and turn counterclockwise to set the outlet pres-
sure to zero.
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure
is approximately 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve (counterclockwise) 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.
Risk of Property Damage. Drain water from air tank may contain oil
and rust which can cause stains.
6. 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, the reinstalled.
OIL
Risk of property damage. Use air compressor oil only. Multi-weight
automotive engine oils like 10W30 should not beuse in air compressors. They
leave carbon deposits on critical components, thus reducing performance and
compressor life.
NOTE: Use 30W compressor oil or a heavy duty SAE 30W, nondetergent, SF
grade or better oil. DO NOT use multi-weight automotive engine oils, they will
reduce compressor life. Under extreme winter condition use SAE-10 weight oil.
NOTE: Crankcase oil capacity is approximately 16 fluid ounces (0.47 L).
Checking
1. The oil level should be to the middle of
C
B
A
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
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and drain
oil into a suitable container.
