NOTICE
WARNING
Recommended Hydraulic Oil
Maximum Hydraulic Input Pressure
The maximum safe hydraulic input pressure to this
motor depends on the pressure rating of the dis-
placement pump to which it is connected.
Use Graco-approved Hydraulic Oil, Part No. 169236
(5 gal) or 207428 (1 gal)) or a premium, ISO grade
46 petroleum-based hydraulic oil containing rust and
oxidation inhibitors and anti-wear agents.
Refer to the lower manual and the pump manual
for the maximum fluid working pressure and the
ratio. Never exceed the maximum fluid working
pressure of the pump. Serious injury or damage to
the equipment may result.
Before using any other type of oil in this motor,
contact your Graco distributor. Unauthorized use of
lesser grade oil or substitutes may void the warranty.
Hydraulic Oil Working Temperature
The recommended hydraulic oil operating tempera-
ture is 80–115_ F (27–45_ C). The motor seals will
wear faster and leakage may occur if the pump is
operated at higher oil temperatures.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
If the hydraulic oil temperature approaches 130_ F
(54_ C), check the hydraulic fluid supply cooling
system, filters, etc. and clean or repair as needed.
Be sure you always shut off the supply line shutoff
valve (E) first, and then the return line shutoff
valve. This is to prevent overpressurizing the motor
or its seals. When starting up the hydraulic system,
open the return line shutoff valve first.
Refer to the complete pump manual for detailed instal-
lation information or contact your Graco distributor.
NOTE: A 1 in. npt seal (7) is supplied in a plastic bag
with the motor. Thread the seal onto the threads of
your hydraulic return line fitting (A). Thread the fitting
into the upper housing (53) and torque as needed.
Then tighten the seal (7) against the motor to provide a
secure seal. See Fig. 1.
NOTICE
Keep the hydraulic system clean
53
To reduce the risk of damaging the hydraulic power
supply, blow out all hydraulic lines with air, flush
thoroughly with solvent, and then blow out with air
again before connecting the lines to the motor.
A
Always plug the hydraulic inlets, outlets and lines
when disconnecting them to avoid introducing dirt
and other contaminants into the system.
Carefully follow the manufacturer’s recommendations
on reservoir and filter cleaning, and periodic changes
of hydraulic fluid.

motors.
7. Any pails used when flushing: Use only metal,
grounded pails when flushing. Make firm metal-to-
metal contact between the metal part of the spray
gun and the pail. Use the lowest possible pres-
sure.
Proper grounding is an essential part of maintaining a
safe system.
8. To maintain grounding continuity when flushing or
relieving pressure, always hold a metal part of the
gun firmly to the side of a grounded metal pail, and
then trigger the spray gun.
To reduce the risk of static sparking, ground the pump.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment. Be
sure to ground all of this equipment:
1. Pump: use a ground wire and clamp as shown to
the right. Loosen the locknut (A) of the grounding
lug and washer. Insert one end of the wire (B) in
the grounding lug (14) and tighten the locknut
securely. See Fig. 2. Connect the other end of the
wire to a true earth ground, as recommended by
your local code. Order Part No. 237569, Ground

ence number in the parts list, for example (21*),
indicates that the part is included in the repair kit.
SKIN INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
