WARNING  
Maximum Hydraulic Input Pressure  
The maximum safe hydraulic input pressure to this  
motor depends on the lower displacement pump to  
which it is connected.  
CAUTION  
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.  
With Graco Displacement Pump Models 207474,  
207655, 210208, 217527, 217339, 222796,  
222801, 222803, 222805, 222810, and 222811  
use a maximum of 1500 psi (10 MPa, 103 bar)  
hydraulic input pressure.  
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  
Models 217022 and 217338  
For Graco Displacement Pump Models 24B923  
and 687055, usa a maximum of 1900 psi (13.1  
MPa, 131 bar) hydraulic input pressure.  
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.  
Never exceed 1000 psi (7 MPa, 70 bar) hydraulic  
input pressure with the motor connected to any  
displacement pump other than those listed above;  
serious injury or damage to the equipment may  
result.  
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.  
Models 235435, 262818, and 24W139  
The recommended hydraulic oil operating tempera-  
ture is 80 – 160_F (27 – 71_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 8.  
If the hydraulic oil temperature approaches 180_F  
(82_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 (57) 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 (40) and torque as needed.  
Then tighten the seal (57) against the motor to provide  
a secure seal. See Fig. 1.  
CAUTION  
Keep the hydraulic system clean  
40  
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.

substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of  
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,

transportation.
