1. Two-way Valve

Pumps with a two-way valve are for use with singleacting cylinders.

A. 1. To extend the cylinder, turn the valve knob counterclockwise to a closed (seated) position. Note:

B. 2. To release pressure, open the valve slowly by turning the knob clockwise to control the load.

Pumps with a three-position, four-way valve are for use with double-acting cylinders. The hose

connection for extending a cylinder can be made to either port. With the handle in the forward position, the

The operator should always release the pressure slowly.

Apply lubricant regularly to all pivot and rubbing points.

Use a good grade of No. 10 motor oil or grease. Do not use dry lubricants.

Air can accumulate in the hydraulic system during the initial set-up or after prolonged use, causing the

cylinder to respond slowly or in an unstable manner. To remove the air:

A. Position the cylinder at a lower level than the pump, and turn the cylinder rod end down.

B. Extend and retract the cylinder several times without putting a load on the system. Air will be released

trapped air from the pump. If this is not done the pump will not function properly (will not build pressure or

has very spongy operation).

To bleed air from the pump, turn the pressure control knob counterclockwise (CCW) (turn lever down or

clockwise on P460 models) and operate the pump handle up and down approximately twenty times. Turn

the pressure control knob clockwise (CW) to its full stop position (turn lever up or CCW on P460 models).

The pump should now be bled of air and ready to use.
