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.
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.
For Graco Displacement Pump Models 24B923
and 687055, usa a maximum of 1900 psi (13.1
MPa, 131 bar) hydraulic input pressure.
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.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
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.
CAUTION
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.
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.
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
The recommended hydraulic oil operating temperature 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.
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 temperature 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.
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.
Refer to the complete pump manual for detailed installation information or contact your Graco distributor.
