Control Valves:

a. 4-Way Valve for Single and Double Acting Tools Pressing pendant control switch directs

pump output to right-hand port.

Releasing pendant control switch directs pump output to left-hand port.

Left hand port output pressure is limited to 3,000 psi.

3-2.

Before starting the pump, make sure that the solenoid valve pendant control switch is not

being accidentally pressed by storage position or wrapping of the control cord. The valve

is designed to direct oil to the 3,000 psi side of the valve when the pendant switch is not

being pressed. Attempting to start the engine with the pendant switch pressed increase the

pull on the starting rope and make the engine hard to start.

3-3.

Bleeding the hydraulic system air can be removed from the system by fully operating and retracting the hydraulic tool several

times with the pump elevated so its reservoir is higher than the tool. Single-acting tools should be inverted. When the trapped air

is removed from the hydraulic circuit, the tool will advance and retract smoothly. Sluggish tool action is usually the first sign of air

in the system.

3-4.

Press the pendant control switch to activate the tool. Releasing the switch automatically releases the tool.

3-5.

Never operate the pump at 10,000 psi without tool movement for more than 1 minute because this could overheat the oil.

4-1.

Maintain Oil Level -- check hydraulic oil level every 30 hours of operation. Add SIMPLEX hydraulic oil when necessary. Oil level

should be no more than 1" from top of reservoir plate with tool retracted and motor off.

Completely change oil at least twice a year. The following conditions require more frequent oil changes :

a. Rigorous duty, where oil temperature may reach 140 F .

b. High humidity environment and extreme changes in temperature that can result in condensation inside the reservoir.

c. Dirty or dusty environments may contaminate the oil.

4-2.

Clean Oil Filter screen Once a Year

a. Loosen and remove reservoir plate bolts . Lift pump unit off the reservoir, being careful not to damage the gasket.

b. Remove debris from screen with a tooth brush.

c. Blow dry and inspect, repeat cleaning as needed.

4-3. Keep areas around pump unobstructed to provide good air flow around the motor and pump. Keep the motor and pump as

clean as possible.
