CAUTION:
The piping between the compressor and the
air receiver should be no smaller than the compressor outlet. Do
not under any circumstances install any kind of shut-off valve
between the compressor and the air receiver. A check valve must
be installed between the compressor and the air receiver.
DRIVE BELT TENSION ADJUSTMENT
NOTE: Drive belt tensioning and pulley alignment are done at the same
time. They are discussed separately for clarity.
WARNING:
compressor, remove the plug from the outlet, 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 5 lbs. (2.3 kg) of
force (see B) midway between the motor pulley and the pump flywheel
(See Fig. 2). 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.
MAINTENANCE
WARNING:

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 air
compressor pump 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.
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. Do not overfill or
under fill.
NOTE: Use full synthetic, non-detergent air compressor oil.

ASSEMBLY AND INSTALLATION

RISK OF INJURY. ALWAYS shut off the
1. Loosen the motor mounting bolts.
2. Shift the motor to the point where the correct deflection exists
(A & B).
3. Retighten the motor mounting bolts to 130-180 in.-lbs.
4. Check to ensure that the tension remained correct.
5. Reinstall the belt guard. All moving parts must be guarded.
PULLEY ALIGNMENT
NOTE:
Once the motor pulley has been moved from its factory set
location, the grooves of the flywheel and pulley must be aligned
to within 1/16" to prevent excessive belt wear.
To check pulley alignment, place a straightedge (see A) against the
pump flywheel (see B) (See Fig. 3). Measure and record the distance
from the straightedge to the edge of the drive belt at point C. Then
measure the distance from the straightedge to the edge of the drive belt
again at points D and E. Both distances should be the same as at point
C. If D or E are different from C, there is a misalignment which must be

corrected before the compressor is run. To correct a pulley misalignment,
use the following procedure.
1. Loosen the motor mounting bolts.
2. Align the motor pulley with the pump flywheel (C-D-E must be equal ).
3. Adjust the proper belt tension.
4. Retighten the motor mounting bolts to 130-180 in.-lbs.
5. Reinstall the belt guard. All moving parts must be guarded.
1. Remove the belt guard.
2. Loosen the motor mounting bolts.
3. Loosen the setscrew on the motor pulley.
4. Align the motor pulley with the pump flywheel (C-D-E must
be equal ).
6. Retighten the motor pulley setscrew.
7. Adjust the proper belt tension.
8. Retighten the motor mounting bolts to 130-180 in.-lbs.
9. Reinstall the belt guard. All moving parts must be guarded.
BREAK-IN OF THE PUMP
After installation is complete, start the unit and run the pump without
load for 30 minutes to lubricate and break in the internal parts.
MAINTENANCE
CHANGING THE OIL
Remove the oil plug (C) and drain the oil until it slows to a drip, then
close. Unscrew the oil fill plug (E) and add compressor oil (approx. 11.35
oz.) until it is between full (A) and add (B). Replace the oil fill plug. Never
overfill or under fill the pump.
NOTE: Use full synthetic, non-detergent air compressor oil.
