MAINTENANCE
This unit starts automatically.
ALWAYS shut off the main power disconnect, and
bleed all pressure from the system before servicing
the compressor, and when the compressor is not in
use. Do not use the unit with the shrouds or belt
guard removed. Serious injury could occur from
contact with moving parts.
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
Drain the moisture from the tank (for instructions, see
“Shutdown” in the operating instructions section).
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. Wear protective eyewear.
Check the level of oil in the pump with the sight glass. The
pump oil level must be between A and B. Do not overfill or
underfill.
NOTE: Use synthetic blend, nondetergent air compressor oil.
Remove the oil plug ( C) and drain the oil until it slows to a
drip, then close. Unscrew the oil fill plug ( D) and add compressor
oil (refer to parts manual) until it is between full ( A) and add (B).
Replace the oil fill plug. Never overfill or under fill the pump.
NOTE: The compressor is pre-filled with synthetic oil. Use
synthetic blend, non-detergent air compressor oil.
NOTE: Drive belt tensioning and pulley alignment are done
at the same time. They are discussed separately for clarity.
This unit starts automatically.
ALWAYS shut off the main power disconnect, and
bleed all pressure from the system before servicing
the compressor, and when the compressor is not in
use. Do not use the unit with the shrouds or belt
guard removed. Serious injury could occur from contact
with moving parts.
Proper belt tension and pulley alignment must be maintained
for maximum drive efficiency and belt life. The correct tension
exists if a deflection (see A) of 1/2” (13 mm) occurs by placing
10 lbs. (4.6 kg) of force (see B) midway between the motor
pulley and the pump flywheel (See Fig. 8). This deflection can
be adjusted by the following procedure. The pulley should be
carefully aligned with the flywheel, and all setscrews should be
kept tight.
1. Remove the front of the beltguard by removing the screws
and washers using a Torx T25 bit.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct deflection exists
(A & B).
4. Retighten the motor mounting bolts to 130-180 in.-lbs.
5. Check to ensure that the tension remained correct.
6. Reinstall the belt guard. All moving parts must be guarded.
NOTE: Drive belt tensioning and pulley alignment are done at the
same time. They are discussed separately for clarity.
