PORTABLE HYDRAULIC POWER KIT SETUP INSTRUCTIONS
SETUP
This is the Safety Alert Symbol used for the SETUP INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.
1. Refer to the parts list and drawing in this manual to identify parts mentioned in this setup procedure.
Before installing the force gage (P39) remove the plug A in the hose end of the pump (01). Thread the gage into the gage fitting
2.
(P41) and connect with the receiver (P42) by turning it clockwise. Make sure the connection is tight to prevent leakage.
3. Open the release valve (P29) by turning it counterclockwise until it stops, then pump the handle 4 or 5 full incremented pump
strokes to purge air from the hydraulic system.
4. Install ram (02) or spreader (03) at the end of hose (P30) and secure the quick disconnect fittings together by hand tightening the
threaded sleeve (R15) on the ram female coupler (R16) to the male coupler (P31) at the end of the hose (P30).

OPERATING INSTRUCTIONS
This is the Safety Alert Symbol used for the OPERATING INSTRUCTIONS section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.
Study the work to be done in order to determine the type ram and other attachments you will be using. Consult the enclosed chart
1.
titled "Applicable force for component set ups" in order to determine the maximum allowable force to be used in your specific
setup. All rams have female hose disconnects attached to them, and the end of the hose has the male quick disconnect attached to it.
Insert the end of the hose (P30) all the way in to the ram's female quick disconnect (S11). Slide the female connector's threaded sleeve
(S10) on to the threads at the end of the hose (P30) and hand tighten. Never use any tools to tighten this connection.
2.
Consult this Owner's Manual section titled APPLICABLE FORCE FOR COMPONENT SET UPS for typical attachment and extension tube
setups and pay very close attention to the corresponding load ratings of certain attachment connections. The use of extension tubes,
ram or plunger toes greatly reduces the hydraulic system's capacity. When using extension tubes, put the shortest tubes on the ends of
the setup.
3.
The pump (1) may be operated in the horizontal or vertical position but the pump (1) must point down when used in the vertical position.
4.
Make sure all hydraulic and attachment connections are fully engaged and tight so ram force is straight in order to avoid off-center load
conditions.
5.
During setup, make sure the hose routing avoids kinks, twists, curls or bends that will impede hydraulic fluid flow. Do not use the hose
(P30) as a means to carry the kit components. Do not subject the hose (P30) to any hazards such as fire, extreme heat or cold, sharp sur-
faces, or heavy impact. IF A HOSE (P30) RUPTURES, BURSTS, OR NEEDS TO BE DISCONNECTED, IMMEDIATELY SHUT THE PUMP
(1) OFF AND OPEN THE RELEASE VALVE (P29) TO RELEASE HYDRAULIC PRESSURE. NEVER GRASP A LEAKING PRESSURIZED
HOSE, FITTING OR COMPONENT WITH YOUR HANDS OR SUFFER SERIOUS INJURY.
6.
Always use the pressure gauge (14) to make sure you are within the required force range when operating the system.
7.
In order to pump the ram (2), it will be necessary to turn the release valve knob (P29) in a clockwise direction until tight. Tighten by hand
only.
8.
Pumping the handle (P34) up and down transfers the hydraulic fluid from the pump's reservoir (P6), through the hose (P30), in to the
cylinder and extends the ram with each incremental pump stroke.
9.
To release the pressure and return the ram (2) back in to its cylinder (R14) , turn the release valve knob (P29) in a counterclockwise direc-
tion very slowly. Turning the release valve knob (P29) slowly will determine the speed in which the ram (2) will retract back into its cylinder
(R14).
IMPORTANT: The pump includes an overload valve that will activate at the pump's rated capacity only. If the setup requires a reduced
rating, the operator is responsible for using the gauge to determine when to stop pumping since the overload valve is set to a higher rat-
ing.
10. Make sure the ram (2) is completely retracted inside its cylinder (R14) before disconnecting the hose from the cylinder.
11. The the hose (P30) and the ram (2) are repeatedly disconnected and exposed to shop or work place floors that are covered with dirt and
debris. It is important to use the dust caps (P32) provided to prevent contaminants from entering the air and hydraulic systems.
12. Based on continuous engagement and disengagement of the hose (P30) from the cylinder (R14), eventually it will become necessary to
add hydraulic fluid to the pump's reservoir (P6). Completely retract the ram before adding hydraulic fluid. Do not overfill in order to avoid
personal injury and hydraulic malfunction. Use only hydraulic jack oil, Chevron Hydraulic Oil AW ISO 32 or its equivalent Unocal Unax
AW 150. Other fluids will cause damage to the hydraulic seals.
