FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
WARNING
Always wear eye protection
when operating or perform-
ing maintenance on this
pump.
WARNING
Do not use damaged, frayed
or deteriorated air hoses
and fittings.
AIR STRAINER
Periodically, clean the Air Strainer Screen as follows:
1.
Shut off the air supply to the pump.
2.
Unscrew the Air Strainer Cap and remove the Air
Strainer Screen.
3.
Clean the Screen in a suitable cleaning solution and
allow to air dry.
IMPELLER ADJUSTMENT
For the most efficient operation of the pump, particularly
against high heads, it is necessary that proper clearance
between the Impeller and the Impeller Cover (52) be
maintained.
1.
Pumps are assembled at the factory with 0.010"
clearance. When, due to wear, this clearance has
increased to 0.032" (1/32"), remove enough Impeller
Cover Shims to obtain the original 0.010" clearance.
White is 0.025"
Green is 0.003"
2.
If decreased efficiency is noted, remove the Impeller
and take some of the Impeller Shims from the Arbor.
Replace the Impeller and tighten the Arbor Nut.

WARNING
WARNING
International Warning Label:
Order Part No. ___________
Rotate the Impeller. Repeat this procedure until
enough Impeller Shims have been removed to cause a
slight drag, then add one 0.010" Shim. Adjust the
clearance between the Impeller Cover and Impeller to
obtain the 0.010" clearance as explained in the
preceding paragraph. Tighten the Impeller Cover Cap
Screws alternately to 20 ft–lb (27.1 Nm) torque.
OILER ADJUSTMENT
The pump should use about 8 fluid ounces of oil during
each four hours of operation. The Oiler is adjusted at the
factory, but since flow rate varies somewhat with
temperature, readjustment may be necessary. The rate of
flow is regulated by an Oiler Adjusting Screw.
To regulate the Oiler:
Remove the Backhead and turn the Oiler Adjusting Screw
(slotted, brass screw). Turning the Screw clockwise
decreases the flow; turning the Screw counterclockwise
will increase the flow. Under no circumstance should the
Screw be backed out beyond the face of the Backhead.

WARNING
Always turn off the air sup-
ply and disconnect the air
supply hose before instal-
ling, removing or adjusting
any accessory on this pump,
or before performing any
maintenance on this pump.
