Operation
1. Turn the pump's release valve clockwise ta a closed position. IMPORTANT: Hand tighten the valve only; applying too
much force to the valve may damage the valve stem.
2. Work the pump handle up and down to sebd oil through the hose to the ram, causing the piston ta extend to the
work piece.
3. Monitor the pressure gauge while completing the application.
Note: The pump is equipped with an overload valve that wi/1 bypass oil back into the pump reservoir in an overload
situation (when the system meets maximum pressure).ln this case, continued pumping wi/1 have no effect on the sys-
tem. 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 fastthe
valve is opened. )
Bleeding Air from the System
Air can accumulate in the hydraulic system du ring 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 a lower level than the pump,with the piston end pointing down
2. Extend and retract the ram severa I times without putti ng a load on the system Air wi Il be releassd into the pump
reservoir.
3. With the ramfully retracted, the pu mp sitting level,and nopressure in the hydraulic system,remove the pump's fil Ier
screw. Fill the reservoir with approved hydraulic fluid until the fluid lev el is within ½ inch (12.7mm) from the top of the
reservoir.
Typical applications & load capacities
When offset attachments are used,the rated capacity of the hydraulic system is reduced 50%. For each extension tube
used the setup, the rated capacity is reduced another 50%. When using two or more extension tubes together,always
poslition the shortest tube farthest away from the ram.

HYDRAULIC CYLINDER KIT PRO 4T / 10T
• 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.
• Sorne 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 PRESSURE. Refer to the instructions in this document for Typical
Applications and Load Capacities.
