MAINTENANCE INSTRUCTIONS FOR
LARGE SUMP TU-FLO
COMPRESSOR 288578 (SPECIAL
APPLICATION)
This compressor is an air-cooled, belt driven, self lubricated,
V-four cylinder compressor. It is driven by an electric motor
and cooling air is supplied by a fan on the driven pulley. The
system air pressure is controlled between 135 psi and 150
psi by a pressure switch starting and stopping the electric
motor.
INSTALLATION
The base mounted compressor should be securely bolted
down with 1/2" grade five or better cap screws torqued to 70
ft. pounds, making sure that motor and compressor pulleys
are aligned and belt tension is correct. The crankcase should
be filled with five quarts (4.7 liter) of SAE 20 W engine oil.
The compressor must always be installed to rotate clockwise
when viewed from the pulley end. The oil pump will not
function if rotation is not correct.

SCHEDULED MAINTENANCE

NOTE: When checking or adding oil or servicing the
crankcase breather, care should be taken to prevent
dirt or foreign material from entering the breather or
oil sump.
Every 7,500 miles or seven weeks, whichever occurs first:
Check oil level - replenish to top of filler plug opening.
Replace both air cleaner filter elements and clean covers.
Check belts and replace if broken, damaged or missing.
Every 15,000 miles or 14 weeks, whichever occurs first:
Remove crankcase ventilator, clean ports and replace with
freshly oiled curled hair.
Every 22,500 miles or 21 weeks, whichever occurs first:
Drain oil and refill with fresh SAE 20 W engine oil. Inspect
all bolts, fittings and plugs to ensure that all are tight.
