WARNING
Safety
DO NOT attempt to make any changes to any of the component
parts or accessories when connected to the power source.
DO NOT adjust, inspect, or clean tool while the tool is connected
to the power source. The tool could accidentally start up and
cause serious injury.
DO NOT lock the tool in the On Position. In an emergency,

Safe Operation & Care
USE THIS TOOL FOR ITS INTENDED PURPOSE ONLY
Any other use can result in injury or property damage.
INSPECT TOOL BEFORE USE. Replace any worn, damaged or
missing parts. A damaged or improperly assembled tool may
malfunction, injuring operator and/or nearby personnel.
INSPECT HYDRAULIC HOSES AND COUPLINGS before each use.
Repair or replace if any cracking, leakage, wear or damage is is
found. Worn or damaged hoses may fail resulting in personal
injury or property damage.
CLEAR WORK AREA of all bystanders and unnecessary personnel
before operating this tool.
KEEP ALL PARTS OF THE BODY AWAY FROM MOVING PARTS.
Failure to observe this warning could result in serious injury.
WARNING
Oil Injection Injury
Hydraulic oil or fluid under the skin is a serious injury. Oil under
pressure can penetrate the skin and may cause dismemberment
or loss of life. Seek medical assistance immediately if such an
injury should occur.
Always wear safety gloves, eye protection and all required
safety equipment when operating or handling this tool.
DO NOT use fingers or hands to attempt to locate a leak.
DO NOT handle hoses or couplers while system is pressurized.
NEVER open or service the system before depressurizing.
WARNING
8
Safe Handling
HYDRAULIC FLUID MAY CAUSE SKIN IRRITATION.
Prevent hydraulic fluid from making contact with skin.
IN THE EVENT OF SKIN CONTACT immediately wash thoroughly.
Failure to observe this warning could result in injury.
CAUTION
Vibration Hazard
Apply just enough pressure to control the tool operation. Applying
excess pressure to the tool may cause operator discomfort or
temporary numbness.
Failure to observe this warning could result in serious injury.
CAUTION
Electrical Shock Hazard
Use only certified nonconductive hoses and fittings. Always
wear and use the necessary clothing, equipment and safety
practices to protect against electrical shock. Failure to follow
these rules can result in serious personal injury or death.
WARNING
CAUTION
General Safety
Ensure that all fellow employees and bystanders are clear
and protected from possible injury caused by this tool or the
operations being performed. Persons in close proximity could
be injured and property damaged if the tool were to malfunction.
This tool should always be used within the limits and purposes
stated by the product manufacturer. Abuse or usage beyond the
manufacturers’ intended purposes could cause damage to the
tool and severe injury to the operator.
Burn Hazard
Do Not connect or disconnect tool, hoses or fittings while power
source is running or while hydraulic fluid is hot. Hot hydraulic
fluid may cause serious burns.
Failure to observe this warning could result in serious injury.
WARNING
9
HOSES AND FITTINGS
There exists the potential for shock in using anything other than
certified nonconductive hoses and hydraulic oil with dielectric
properties, when using system components near energized
electrical lines. Failure to recognize these conditions could
cause electrocution.
Hoses and fittings used with this tool must comply with S.A.E. J1273 which
covers recommended practice for selection, installation, and maintenance of hose and
hose assemblies. The correct hoses and fittings are available from your supplier.
WARNING: Failure to comply with these warnings could result in severe bodily injury.
WARNING
UNIT/HOSE CONNECTIONS
ALWAYS SHUT OFF pump/power source and move flow selector
to OFF before connecting or disconnecting system components.
ALWAYS DEPRESSURIZE hydraulic system before slowly
disconnecting this unit or any of the systems components.
ALWAYS TIGHTEN couplings completely. Loose or improperly
tightened couplings will not allow fluid to pass through the
hose creating a blockage in the supply or return line.
ALWAYS INSPECT HOSES AND CONNECTORS before connection
to tool. Replace or repair if any leakage is evident. Leakage is a sign
of deterioration in component parts. Worn or leaking parts must be
repaired or replaced, or tool damage or severe injury could result.
WARNING
HOSE INSTALLATION
Care must be taken to assure the correct connection of the hoses
to the pressure and return ports.
Connect the return hose to the return port on the power source,
then to the return port on the tool.
Connect the pressure hose to the pressure port on the tool, then
to the pressure port on the power source.
Operation with hydraulic flow reversed can cause malfunction.
Failure to fully comply can result in severe injury or death.
CAUTION
10
HOSES AND FITTINGS
Care must be exercised in the use of hose and fi ttings for use on hydraulic tools, especially
in confined areas. Any obstruction or abrasive surrounding could damage the hose and cause a
serious accident. Always use the recommended hose for the tool that is being used. Always consult
the dealer or distributor for the correct hoses and purchase from him to ensure, from a safety
standpoint that the materials used in the manufacture of the hoses is to the correct specification
for the application. Fittings must meet the standards established by the industry to adequately
assure safety. Poor quality or low rated fittings are not to be used. They invite a serious accident.
Length: Hose must be the correct length for the general use of the tool or for the specific function it is
to provide. Pressure surge is an important factor in the selection of hoses. The hose should be rated
above the expected surge pressure to ensure adequate safety. Hoses that are too long will have a
tendency to coil, kink, or move in multiple directions creating a safety hazard. Hoses that are too long
will rub or chafe against the ground or projecting objects, seriously shortening the life of the hose. It
may be advisable to carefully restrain a hose which is temporarily too long for the current application.
Pressure surge can cause whipping, and seriously damage the hose. Always keep the hose length
as short as possible for the operation which is it intended.
Size: The hose must be large enough to carry the pressurized flow of fluid to the end application
without creating undue heat generation or excessive turbulence. These factors could cause excessive
wear to the hose from any or all of the above reasons.
Pressure: Hose selection must be made so that the recommended maximum operating pressure is
greater than the system pressure. A surge or sudden drop in pressure will cause the hose to deteriorate
faster if the maximum pressure of the hose is significantly below the surge pressure. A hose with a
top rate of pressure as the line pressure of the installation is not an accepted safety practice. Always
err on the side of safety.
Temperature: Hose can be seriously damaged by passing over or near hot objects. Avoid any situation
that will heat the hose. Serious damage and/or failure will occur.
Unusual Applications: Careful thought and research should precede installation of hoses. Thorough
and protected testing, with appropriate safety guards, must be done to avoid injury before general use.
Connections: Hoses must have the proper end fittings in order to mate correctly with connectors.
Worn or damaged connectors and worn end fittings on the ends of the hose can cause a failure.
Pressure surge can cause a slow or sudden failure at the connection causing serious damage or injury.
Safety Check: Before using any installation, perform a thorough checkout to determine if any of the
above or unforeseen problems occur. Initial testing with safety guards is an invaluable safety precaution.
Always consult the distributor or manufacturer for the correct specifications regarding any of
the items discussed above. The correct hoses and fitting are available from your supplier.
There exists the potential for SHOCK in using anything other than certified non-conductive hoses
and hydraulic oil with dielectric properties when using system components near ENERGIZIZED
ELECTRICAL LINES. Failure to recognize these conditions could cause ELECTROCUTION.
Hoses and fittings used with this tool must comply with S.A.E.
J1273 recommended practice for selection, installation, and
maintenance of hose assemblies.
FAILURE TO COMPLY WITH THESE WARNINGS
COULD RESULT IN SEVERE BODILY INJURY.
