
Use only Compac components rated specifically for the Compac repair kit used.

Do not alter or modify any Compac repair kit component.

Some setup components are rated less than the capacity of the pump and cylinder!
Installation:
1. Connect the flexible hose to the pump and cylinder. It is not necessary to use pliers to tighten
the threaded collar.
2. There are two different methods of connecting extension tubes and adopters. "Quick-Lock"
connections where extension tubes, adapters and piston slip fit together. Also threaded
connections are used. Make sure all "Quick-Lock" and threaded connections are fully engaged
before using.
3. There is a vent on some pumps. The vent screw is located in the top rear end of the pump's
reservoir. The vent screw must be opened by turning it in a counter clockwise direction two full
turns before operating the pump.
4. Sometimes air gets trapped in the hydraulic system when the hose is first hooked up to the
cylinder. An air bound hydraulic system feels spongy when pumped and sometimes the pump
will not pump in full incremental pump strokes.
Trouble shooting:
Purging air from the hydraulic system:
1. Open the release valve in the side of the hydraulic pump by turning it two full turns in a counter
clockwise direction.
2. Activate the pump handle up and down about 15 times.
3. Close the release valve by turning it in a clockwise direction until tight.
4. Activate the pump handle until the piston is extended all the way out.
5. If the condition seems better but is still detectable, repeat steps "1" through "4" until all air is
purged from the system.
Operating instruction:
Compac repair kits provide the user with an effective method to accomplish the following basic
tasks with the pilling, clamping, spreading, pushing, lifting, pressing and straightening. The basic kit
consists of a hand operated portable pump, hydraulic hose, cylinder, extension tubes and adapters.
The wide range of setup combinations for specific job requirements makes it impossible to
document every conceivable application.
1. Study the type of work to be done and determine the components (extension tubes and
adapters) needed for the setup.
2. Make sure all threaded components are free of dirt, dust, nicks, cuts, etc. Always use the
threaded protector ring on all cylinders when the threads are not being used.
3. The pump can be operated in a horizontal position or in a vertical position with the hose
pointing down. Cylinders can be used in any position provide the setup is safe and secure.
4. Once the kit components are properly connected and are positioned in the setup, turn the
pump's release valve in a clockwise direction until hand tightened. Slowly operate the pump
handle so the piston is extended to meet the load. At the same time make sure extension tubes
and adapters (in-line or off-center) are stable and secure. If the setup becomes unstable, turn
the pump's release valve in a counter clockwise direction to remove the cylinder pressure and
then adjust or change the setup accordingly. NOTE: All cylinders have return springs that return
them to their retracted positions when the pump's release valve is opened. The pump is
equipped with an overload system that will send the oil back into the pump reservoir if the
system is overloaded. Stop pumping and release the load if the system is overloaded.
5. After work is completed, turn the pump's release valve slowly in a counter clockwise direction to
release pressure from the cylinder.
