MAINTENANCE

MONTHLY: 

Drain moisture from Oil Tank and Air Tank. For instruction see 

OIL TANK CONDENSATION DRAIN

 and 

AIR TANK CONDENSATION DRAIN

.

YEARLY: 

Perform oil change, Oil Filter replacement, Moisture Separator replacement, and Air Filter replacement.

NOTE:

 For heavy use in high humidity conditions, it is recommended to drain the oil tank condensation weekly.

If operating in excessively dusty or dirty environments, vacuum debris or dust from the oil cooler fins and periodically follow the 

AIR FILTER CHANGE

 procedure 

to remove, blow-out and re-install Air Filter Element.

OIL CHANGE ONLY

•  Move Power Switch to the “OFF” position 

(FIG 1)

. Release pressure from Tank until Tank Pressure Gauge indicates 0 PSI.

•  Disconnect Compressor from power supply.
•  Remove the drain hose from the Moisture Drain System Barbed Fitting and securely position it above a suitable drain pan, then slowly open the  

Oil Drain Valve 

(FIG 4)

TIP: 

It is advisable to place spacers under the opposite side Casters lifting the Compressor slightly on that end to force the maximum amount of oil  

to drain from the Reservoir into a suitable container 

(FIG 14)

.

BURN HAZARD! 

  Significant heat is generated during operation. Components and oil may be hot. Allow to cool a minimum of 1 hour after last use 

before servicing to avoid burns.

INJURY HAZARD! 

  Before performing any service, turn Power Switch to the “OFF” position (FIG 1). Shut off breaker or disconnect power supply.  

Release pressure from Tank until Gauge indicates 0 PSI.

 

INJURY HAZARD! 

  The Oil Tank may be under pressure. Opening the Oil Drain Valve or removing the Fill Plug under pressure can cause oil to be blown out at 

high velocity. Move Power Switch to the “OFF” position, release pressure from the Tank until Tank Pressure Gauge indicates 0 PSI,  and 
disconnect Compressor from power supply before opening Drain Valve or removing Fill Plug. Always wear appropriate eye protection.

 

  Used Oil is a polluting material and should be disposed of in compliance with local regulations.

•  After the oil has drained, close the Oil Drain Valve completely then re-connect the drain hose to the Moisture Drain System Barbed Fitting.
•  Remove the Oil Fill Plug/Dipstick from the upper front area of the Oil Reservoir 

(FIG 2)

.  

NOTE:

 Do not lose the Oil Fill Plug/Dipstick seal.

•  Add #31718 Eastwood Synthetic Scroll Compressor Oil to the fill port of the Oil Reservoir using a suitable funnel 

(FIG 5)

.

•  With the Compressor sitting on a level surface, check oil level by observing the level on the Dipstick. The oil level is acceptable when it is between the 

marks 

(FIG 3)

. If the oil level is below the bottom mark, oil must be added.

•  Check the condition of the seal then replace Oil Fill Plug/Dipstick and tighten securely.
