IMPORTANT SAFETY INFORMATION
SAFETY
ALERT
SYMBOL
Skin injection hazard:
• Do not use hands to check for
leaks.
• Do not hold hose or couplers while
the hydraulic system is pressurized.
• Depressurize the hydraulic system
before servicing.
Oil under pressure easily punctures
skin, causing serious injury, ­gangrene,
or death. If you are injured by escaping oil, seek medical attention
immediately.
This symbol is used to call your attention to hazards
or unsafe practices which could result in an injury or
property damage. The signal word, defined below,
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.
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection could
result in serious eye injury from flying
debris or hydraulic oil.
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.
Use chains with the following characteristics:
• 7.1 mm (9/32") link thickness
• Alloy steel material
• 64 kN (14,400 lb) minimum breaking strength
An underrated chain may break during operation.
Failure to observe this warning could result in severe
injury or death.
Read and understand all of the
instructions and safety information
in this manual before operating or
servicing this tool. Refer also to the
Instruction Manual, which is listed
under “Other Publications.”
Failure to observe this warning could
result in severe injury or death.

IMPORTANT SAFETY INFORMATION
Do not exceed the following hydraulic power source
maximums:
• Hydraulic flow: 22.7 l/min (6 gpm)
• Pressure relief: 138 bar (2000 psi)
• Back pressure: 13.8 bar (200 psi)
Failure to observe this warning could result in severe
injury or death.
Do not reverse hydraulic flow. Operation with
­hydraulic flow reversed could cause tool malfunction.
Connect the pressure (supply) hose and tank (return)
hose to the proper ports.
Do not change accessories, inspect, adjust, or
clean tool when it is connected to a power source.
Accidental start-up can result in serious injury.
Failure to observe this warning could 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 could cause serious burns.
Procedure for connecting or disconnecting hydraulic
hoses, fittings, or components:
1. Move the flow lever on the hydraulic power
source to the OFF position.
2. Stop the hydraulic power source.
3. Follow the sequence under “Hose Connections”
in the Instruction Manual to prevent pressure
buildup. In case some pressure has built up,
loosen hoses, fittings, or components slowly.
Note: Keep all decals clean and legible, and replace
when necessary.
When disposing of any components (hydraulic hoses,
hydraulic fluid, worn parts, etc.), do so in accordance
with federal, state, and local laws or ordinances.
