3.  The safety valve should 

automatically close at approximately 
40 psi - 50 psi. If the safety valve 
does not allow air to be released 
when you pull on the ring, or if 
it does not close automatically, it 
MUST be replaced. 

DraIn tank
1.  Turn compressor off and release 

pressure from system. (To release 
pressure from system, pull ring on 
ASME safety valve. Deflect escaping 
air by shielding valve with one hand 
as you pull ring with other hand.) 
Pull ring until tank is empty.

2.  Drain moisture from tank by 

opening drain valve underneath 
tank. Tilt tank to remove all 
moisture.

3.  Clean dust and dirt from tank, 

air lines and pump cover while 
compressor is still OFF.

OIL CHanGe
1.  Allow compressor to run and warm 

up oil. Unplug unit.

2.  Position a pan under pump end of 

unit.

3.  Remove drain plug. Allow oil to 

collect in pan. Tilt unit to completely 
drain.

4.  Replace drain plug, fill pump to 

center of sight glass. Use Chevron 
synthetic 5W-30, Mobil 1 5W-30 or 
10W-30 synthetic motor oil. Using  

other types of oil will cause starting 
problems.

5.  Change oil after every 50 hours of 

use.

Intake aIr FILter MaIntenanCe
Removal, Inspection and Replacement 
(Figure 6).

The intake filter element should be 
removed and checked periodically. 
A clogged intake filter can decrease 
compressor performance and cause the 
compressor to overheat.
1.  Rotate the filter cover counter-

clockwise and remove.

2.  Remove the filter element and 

inspect.

3.  If the filter element is dirty or 

clogged, replace it. 

4.  Reinstall filter and cover.
IMPOrtant: Locate unit as far from 
spraying area as hose will allow to 
prevent overspray from clogging filter.

enD OF OPeratIOn/StOraGe
1.  Turn AUTO/OFF switch to the OFF 

position.

2.  Unplug power cord from wall outlet 

and wrap around handle to prevent 
damage when not in use.

3.  Wearing safety glasses drain tank of 

air by pulling the ring on the safety 
valve. Use other hand to deflect 
fast moving air from being directed 
toward your face.

4.  Drain tank of condensation by 

opening drain valve on bottom of 
tank. Tank pressure should be below 
10 psi when draining tank.

5.  Air hose should be disconnected 

from compressor and hung open 
ends down to allow any moisture to 
drain.

6.  Compressor and hose should be 

stored in a cool, dry place.

Moisture in compressed air will form into droplets as it comes from an air 
compressor pump. When humidity is high or when a compressor is in continuous 
use for an extended period of time, this moisture will collect in the tank. When 
using a paint spray or sandblast gun, this water will be carried from the tank 
through the hose, and out of the gun as droplets mixed with the spray material.
IMPOrtant: This condensation will cause water spots in a paint job, especially 
when spraying other than water based paints. If sandblasting, it will cause the 
sand to cake and clog the gun, rendering it ineffective.
A filter in the air line, located as near to the gun as possible, will help eliminate 
this moisture.
