SAFETY
ALERT
SYMBOL
IMPORTANT SAFETY INFORMATION
Skin injection hazard:
Oil under pressure easily punctures
skin causing serious injury, gangrene
or death. If you are injured by
escaping oil, seek medical attention
immediately.
• Do not use fingers or hands to
check for leaks.
• Do not hold hose or couplers while
operating the power source.
• Depressurize the hydraulic system
before servicing.
Do not inspect, adjust, or clean tool when it is
connected to a power source. Accidental start-up
can result in serious injury.
Do not operate the pump if the impeller blades
are exposed. After assembly, install the inlet
screen before operating the pump.
Failure to observe this warning can result in
severe injury or death.
Before operating this tool, see the safety information
and operating instructions in the Operation Manual.

IMPORTANT SAFETY INFORMATION
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection can
result in serious eye injury from
flying debris or hydraulic oil.
Note: Keep decals clean and legible. Replace decals
when necessary—see the decals listed in the
Parts and Specifications manual.
Do not disconnect tool, hoses, or fittings while
the power source is running or if the hydraulic fluid
is hot. Hot hydraulic fluid can cause serious burns.
Do not reverse hydraulic flow. Operation with
hydraulic flow reversed can cause tool malfunction.
Connect the supply (pressure) hose and return
(tank) hose to the proper tool ports.
Hydraulic oil can cause skin irritation.
•Handle the tool and hoses with care to prevent
skin contact with hydraulic oil.
•In case of accidental skin contact with hydraulic
oil, wash the affected area immediately to remove
the oil.
Failure to observe these precautions can result
in injury.
Do not exceed the maximum hydraulic flow,
pressure relief or back pressure listed in the
Specifications and Parts manual.
Failure to observe this warning can result in
severe injury or death.
Procedure for disconnecting hydraulic hoses, fittings
or components:
1. Move the flow lever on the hydraulic power
source to the OFF position.
2. Stop the power source.
3. Follow the sequence under Disconnecting
Hoses to prevent pressure buildup. In case
some pressure has built up, loosen hoses,
fittings or components slowly.

into bearings. Spin shaft. If shaft does not spin
smoothly, replace bearings and drive shaft.
2. Motor Cap (12) and Motor Body (1): Inspect mating
surfaces, gear cavities, oil passageways, etc. for
grooves or nicks. If any component shows wear or
damage, replace the component as an assembly
with the bearings already pressed in.
3. Inspect all other disassembled components for
cracks, grooves, or nicks.

surfaces which they must slide over.
When installing an O-ring which must slide over sharp
surfaces, use a rolling motion and be careful not to
damage the O-ring.
Wherever the assembly results in metal-to-metal
contact, coat the surfaces with hydraulic fluid or O-ring
lubricant.
