indicates the severity of the hazard. The message
after the signal word provides information for preventing or avoiding the hazard.
Immediate hazards which, if not avoided, WILL result
in severe injury or death.
Do not operate the pump if the impeller blades are
exposed. Do not operate the pump without the
base legs and base plate in place.
Failure to observe this warning can result in
severe injury or death.
Do not inspect, adjust, or clean tool when it is
connected to a power source. Accidental startup
can result in serious injury.
Hazards which, if not avoided, COULD result in severe
injury or death.
Hazards or unsafe practices which, if not avoided,
MAY result in injury or property damage.
Before operating this tool, see the safety information
and operating instructions in the Operation Manual.
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

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.
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.
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.
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 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.
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.
