Installation

WARNING

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.

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.

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

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.

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.

NOTICE

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

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.

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.

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.
