MAINTENANCE

I WARNING

To avoid personal injury, always shut off and unplug the

compressor and relieve all air pressure from the system before performing

any service on the air compressor.

Regular maintenance will ensure trouble–free operation. Your electric powered

air compressor represents high–quality engineering and construction; however,

even high–quality machinery requires periodic maintenance. The items listed

below should be inspected on a regular basis

DRAINING THE TANK (Fig. 6)

I WARNING

Condensation will accumulate in the tank. To

prevent corrosion of the tank from the inside, this moisture must

be drained at the end of every workday.

I WARNING

Be sure to wear protective eyewear. Relieve the

air pressure in the system and open the petcock on the bottom of

the tank to drain.

CHECKING THE OIL

Check the level of oil in the pump with the sight glass. The pump oil level must

be between A and B (See Fig. 7). Do not overfill or underfill.

NOTE: Use synthetic blend, non-detergent air compressor oil.

CHANGING THE OIL

Remove the oil plug (C) (Fig. 7) and drain the oil until it slows to a drip, then

close. Add oil to the pump by first removing the breather plug (E). Add oil until

the level viewed through the sight glass (D) is between FULL (A) and ADD (B).

Never overfill or underfill the pump.

NOTE: The compressor is pre-filled with synthetic oil. Use synthetic blend, non-

detergent air compressor oil.

A = Full

B = Add

C = Oil drain plug

D = Oil level sight glass

E = Oil fill plug
