Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. When
these symbols appear in the body of this manual, refer back to these Warnings. Additional, product-specific warnings
may be found throughout the body of this manual where applicable.
WARNING
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system
component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request MSDS from distributor or retailer.
• Do not leave the work area while equipment is energized or under pressure. Turn off all equipment
and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only.
• Do not alter or modify equipment.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulations.
BURN HAZARD
Equipment surfaces and fluid that’s heated can become very hot during operation. To avoid severe
burns:
• Do not touch hot fluid or equipment.
PERSONAL PROTECTIVE EQUIPMENT
You must wear appropriate protective equipment when operating, servicing, or when in the operating
area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to:

Disassembly
1. Relieve pressure. See system manual for pressure
relief instructions.
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 maximum hydraulic oil operating temperature is
160 °F (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 160 °F
(71 °C), check the hydraulic fluid supply cooling system, filters, etc. and clean or repair as needed.
Keep the hydraulic system clean
To reduce the risk of damaging the hydraulic driver,
verify that the hydraulic power supply fluid lines and
reservoir are clean and free from contaminants.
2. Remove vertical hydraulic driver from system. See
system manual for instructions.
3. Use two people to lift and clamp the cylinder (1) in a
vise.
4. Remove elbow fittings (4) and pipe plugs (5) from
seal housings (2).
NOTICE
To prevent damage to the driver, avoid getting dust
or dirt in the driver during service.

5
Carefully follow the manufacturer’s recommendations on reservoir and filter cleaning, flushing, and
periodic changes of hydraulic fluid.
Always plug the hydraulic inlets, outlets and lines
when disconnecting them to avoid introducing dirt
and other contaminants into the system.
5. Place a waste container below the seal housing (2)
Required Tools
• Vise with soft jaws
• Set of adjustable wrenches
• O-ring pick
• 1/2 in. hex key
• Rubber mallet
• 18 in. pipe wrench
• Torque wrench
• Anti-seize lubricant
