WARNING

• Study, understand and follow all instructions.

• Do not overload ram beyond its rated capacity.

• When attachments are used, bowing of extension tubes or
slipping attachment often indicates overloading.

• Always reduce the overall capacity of your set by 50% for
each extension tube used.

• Never operate this equipment without using some type of
force measuring equipment to verify the applied load.

• Make certain that attachments are positively engaged before use.

• Do not use this product for any purpose other than that
for which it is intended.

• Failure to heed these warnings may result in loss of load,
damage to the kit, and/or failure resulting in personal injury
and/or property damage.

• Do not remove or obscure this label.

• Make sure the lift point is stable and properly centered on the ram.

• Please keep this equipment away from excessive heat or fire.

• Please refill with hydraulic fluid only and be sure that no dirt gets
into the hydraulic system

• For safety sake, please read owner’s manual carefully.

SAFETY PRECAUTIONS

HOSE

• Before operating the pump, tighten all hose connections using
the correct tools. Do not over tighten; connections need only be
secure and leak-free. Over tightening can cause premature
thread failure or high pressure fittings to split at pressures lower
than their rated capacities.

• Should a hydraulic hose ever rupture, burst, or need to be
disconnected, immediately shut the pump OFF, and open the
control valve to release all pressure. NEVER grasp a leaking,
pressurized hose with your hands; the force of escaping
hydraulic fluid could cause serious injury.

• Do not subject the hose to any potential hazard such as fire,
extreme cold or heat, sharp surfaces, or heavy impact. Do not
allow the hose to kink, twist, curl, or bend so tightly that the fluid
flow within the hose is blocked or reduced. Do not use the hose to
move attached equipment. Periodically inspect the hose for wear
because any of these conditions can damage the hose and
result in personal injury.

• Hose material and coupler seals must be compatible with the
hydraulic fluid used. Hoses also must not come in contact with
corrosive materials such as creosote impregnated objects and
some paints. Consult the manufacturer before painting a hose.
Never paint couplers. Hose deterioration due to corrosive
material can result in personal injury.

PUMP

• Do not exceed the maximum capacity of the pump or tamper with
the internal high pressure relief valve. Creating pressure beyond
the rated capacity can result in personal injury.

• Completely retract the ram before opening the filler screw on the
pump to add hydraulic fluid. An overfill can cause personal injury
due to excess reservoir pressure created
when rams are retracted.

Ram

• Do not exceed the maximum capacity of the ram. Creating
pressure beyond the rated capacity can result in person injury.

• Do not set poorly-balanced or off-center loads on a ram.
The load may tip and cause personal injury.

OPERATION INSTRUCTIONS

Setup

The pump may be operated in a horizontal
position or in a vertical position with the
head pointing down as shown.

1. Assemble the hose between the pump and ram.

2. Determine the appropriate attachment for your
application; assemble the attachment to the ram piston.

IMPORTANT

• The use of extension tubes or off-center attachments greatly
reduces the capacity of the hydraulic system. When using
extension tubes, put the shortest tubes on the ends of the
setup; never put the shortest tubes in the middle of the setup.

• Some components in this set do not match the maximum
pressure rating of the pump and ram. USE A PRESSURE
GAUGE IN THE SYSTEM TO MONITOR HYDRAULIC PRE
SURE. Refer to the instructions in this document for Typical
Applications and Load Capacities.

Operation

1. Turn the pump’s release valve clockwise to a closed position.

IMPORTANT: Hand tighten the valve only; applying too much
force to the valve may damage the valve system.

2. Work the pump handle up and down to send oil through the hose
to the ram, causing the piston to extend to the work piece.

3. Monitor the pressure gauge while completing the application.

Note: The pump is equipped with an overload valve that will
bypass oil back into the pump reservoir in an overload
situation (when the system meets maximum pressure). In
this case, continued pumping will have no effect on the
system. If an overload situation commonly occurs, a higher
capacity set is needed.

4. To release pressure, slowly turn the release valve
counterclockwise. (The release speed is controlled by how fast
the valve is opened.)

BLEEDING AIR FROM THE SYSTEM

Air can accumulate in the hydraulic system during the initial
setup or after prolonged use, causing the ram to respond slowly
or in an unstable manner. To remove the air:

1. Place the ram at lower level than the pump, with the piston
end pointing down.

2. Extend and retract the ram several times without putting a load
on the system. Air will be released into the pump reservoir.

3. With the ram fully retracted, the pump at sitting level, and no
pressure in the hydraulic system, remove the pump’s filler screw.
Fill the reservoir with approved hydraulic fluid until the fluid level
is within 1/2” (12.7mm) from the top of the reservoir.
