NOTE:Once themotor p ulley h asbeen moved f rom itsfactory
setlocation, thegrooves ofthe flywheel andpulley m ust
bealigned t owithin 1/16" toprevent excessive belt w ear,
Tocheck p ulley a lignment, remove thebelt g uard andplace
astraightedge
(see A)against thepump flywheel (see B)(See
Fig. 9). 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 misatignment
which must be
corrected before the compressor is run. To correct a pulley
misatignment, use the following procedure.
1.
Remove the front of the bettguard by removing the 4 screws
(turn counter-clockwise
using T25 Torx wrench) and 4
washers.
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 ).
5.
Retighten the motor pulley setscrew to 85-90 in.-Ibs.
6.
Adjust the proper belt tension.
7.
Retighten the motor mounting bolts to 130-180 in.-lbs.
8.
Reinstall the belt guard. All moving parts must be
guarded.

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.

2.
Loosen the motor mounting bolts.
3.
Shift the motor towards the pump to the point where the belt
can be easily removed and installed.
4.
Remove and replace belt. NOTE: The belt must be centered
over the grooves on the flywheel and motor pulley.
5.
Shift the motor back to the point where the correct deflection
exists (see "Drive Belt Tension Adjustment").
6.
Retighten the motor mounting bolts to 130-180 in.-Ibs.
7.
Check to ensure that the tension remained correct.
8.
Reinstall the belt guard. All moving parts must be guarded.

LWAYS 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.
1.
Turn air compressor off,
remove the power cord from
the outlet or lock out the
power supply and relieve all
the air pressure from the tank
(refer to "Shutdown" in
Operating Instructions).
Make sure the compressor
has cooled down before
servicing.
2.
Using the appropriately
sized wrench, loosen the
compression
nuts (A) on the
check valve (B) and pump
head (C). Remove the
transfer tube (D).

4.
Making note of the orientation for reassembty, unscrew the
check valve from the tank (counterclockwise)
using a 1-3/16"
open end wrench.
5.
Using a pencil or screwdriver, carefully
Screwdriver
or
push the valve disc up and down. If the
pencil
valve disc does not move freely up and
down, the check valve needs to be
cleaned or replaced.
6.
Clean the check valve with warm soapy
water and make sure to dry thoroughly
before reinstalling. If the disc valve still
does not move freely up and down, it will
need to be replaced.
7.
Apply thread sealant to the check valve
threads and reinstall into the tank by
turning clockwise. Make sure it is the
same orientation as when it was

removed.
8.
Replace the bleeder tube and tighten compression
nut.
9.
Replace the transfer tube and tighten compression nuts.
10. Perform the "Break-in of the pump" procedure in the
Operating Instructions to make sure there are no leaks and
the check valve is working properly.
