1. See torque wrench instructions for amount of pressure required to produce desired torque.
2. Loosen lock nut and back out relief valve to prevent unintended pressure builds up.
3. Turn pump on. Press and hold the "ADVANCE" switch, and read pressure gauge.
4. While holding the switch, turn relief valve in (clockwise) to increase pressure or out
(counter-clockwise) to decrease maximum pressure. Repeat until correct pressure is obtained.
5. Tighten lock nut on the relief valve to maintain setting.
6. Run pump several times to test this setting before setting tool on the nut.
AFTER COMPLETING THE JOB
Before disconnecting hoses, fittings, etc., first be sure the tool is unloaded and retracted, then
unplug the power cord. The pump is designed to cycle the valve upon powering off to release
pressure.
PERIODIC MAINTENANCE
Completely change the hydraulic oil and clean the intake screen and magnet (located in
the reservoir) twice a year. If equipped, change the external oil filter twice a year (Use the
manufacturer oil only, Model # AO1, 1 gallon). Change the oil more frequently when used
in extremely dusty areas or when the oil has been overheated. Using oil other than the
manufacturer Brand may void the pump's warranty.
The following conditions require more frequent oil changes.
•Rigorous duty, where oil temperature may reach 150˚ F.
•High humidity environment and extreme changes in temperature that can result in
condensation inside the reservoir.
•Dirty or dusty environments that may contaminate the oil.
•Frequent connection and disconnection of hydraulic hoses and components.
WARNING: The electrical power cord must be disconnected from electrical outlets before
performing maintenance or repair procedures.
MAINTAIN OIL LEVEL
Check hydraulic oil level every 30 hours of operation (sight gauge should be completely
covered in oil when all tools are retracted. Add the manufacturer oil (Model # AO1 – 1 gallon)
when necessary. Oil level should be no more than 1" from top of reservoir plate – with cylinders
retracted and motor off.
CLEAN OIL INTAKE SCREEN ONCE A YEAR
Loosen and remove reservoir plate bolts. Lift pump unit off the reservoir, being careful not to
damage the gasket.
