Installation
NOTICE

WARNING
The maximum safe hydraulic input pressure to this
motor depends on the pressure rating of the displacement pump to which it is connected.

Recommended Hydraulic Oil
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.

Maximum Hydraulic Input Pressure

WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 7.
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.

NOTICE

Hydraulic Oil Working Temperature
The recommended hydraulic oil operating temperature is 80–115F (27–45C). The motor seals will
wear faster and leakage may occur if the pump is
operated at higher oil temperatures.
If the hydraulic oil temperature approaches 130F
(54C), check the hydraulic fluid supply cooling
system, filters, etc. and clean or repair as needed.
Refer to the complete pump manual for detailed installation 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.

Keep the hydraulic system clean
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.

53
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.

Pressure Relief Procedure

WARNING
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:





are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tip.

Before you start:
Be sure you have all necessary parts on hand.
1. Repair Kit 223654 is available. The kit must be
purchased separately. An asterisk behind a reference number in the parts list, for example (21*),
indicates that the part is included in the repair kit.
2. Clean all parts as you disassemble them and
inspect them for wear or damage. Replace parts
as necessary. Use Loctite TL–242 thread
sealant, or the equivalent, when thread sealant is
specified.

in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
