Install the Hand-Operated Hydraulic Pump
When space permits, the hand-operated hydraulic pump can be mounted to the
sheet metal base of the load unit. If not, other mounting arrangements will need
to be devised. As a minimum, mount the pump on a board or on an adjacent
tabletop.
Note In order for the pump to operate, the reservoir end of the pump assembly
must be higher than the output end (or at least the same elevation).
1. Mount the pump. The preferred location is on the base of the load unit.
2. Connect hoses between the pump and the grips. Tighten both of the hoses at
the pump end. At the grip ends, leave the hoses connected, but loose
3. With the reservoir end of the pump pointed up, fill the reservoir with Quaker
Quintolubric hydraulic fluid, or equivalent. If the level is ever low, add more
hydraulic fluid.
4. With the hoses loose at the grip ends, close the pump’s pressure release
valve and actuate the pump until all air is expelled from the hoses, and then
tighten the hose fittings at the grips.
5. Apply 13.8 MPa (2000 psi) pressure to the grips and check for leaks at all
fittings.
6. After ensuring that all connections are leak free, open the pressure release
valve to release the pressure in the grips.
