NOTE:Once themotor pulley 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 misalignment which must be
corrected before the compressor is run. To correct a pulley
misalignment,
use the following procedure.
1.
Remove the front of the bettguard by removing the 5 screws
using a Phillips head screwdriver.
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.-tbs.
6.
Adjust the proper belt tension.
7.
Retighten the motor mounting bolts to 130-180 in.-tbs.
8.
Reinstall the belt guard. All moving parts must be
guarded.

DRIVE BELT REPLACEMENT
__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.
1.
Remove the front of the bettguard by removing the 5 screws
using a Phillips head screwdriver.
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.-tbs.
7.
Check to ensure that the tension remained correct.
8.
Reinstall the belt guard. All moving parts must be guarded.
TO REPLACE OR CLEAN CHECK VALVE
__This
unit starts automatically.
r 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.
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).
3.
Making note of the

head -4-_
orientation for reassembly, unscrew the check valve from
the tank (counterclockwise)
using a 7/8" open end wrench.
4.
Using a pencil or screwdriver, carefully
push the valve disc up and down. If the
valve disc does not move freely up and
down, the check valve needs to be
cleaned or replaced.
5.
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.
6.
Apply thread sealant to the check valve
threads and reinstall into the tank by
turning clockwise.
7.
Replace the transfer tube and tighten
compression
nuts.

8.
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.
