Page 16: Starting The Pump And Motor
STARTING THE PUMP AND MOTOR IMPORTANT: Prior to start-up: 1. Start and stop the electric motor in order to check proper rotation. There are arrows clearly marked on the motor indicating the correct rotation. If this is incorrect, check the wiring to the motor leads. 2. -
Page 17: Inching
NOTE Ram may not retract if the RELIEF VALVE has been backed out too far. INCHING Set the selector switch to JOG DOWN. Simultaneously actuate and maintain actuation of both CYCLE START buttons to the desired position of the ram. Release of either button allows the ram to stop. -
Page 18: Set-Up
SET-UP JOG the press to your desired lower stop position allowing ram to exert full pressure against a set up block or workpiece. NOTE Set-up tooling before setting pressure on the ram. Adjust the pressure by loosening the relief valve LOCKNUT and turning the relief valve KNOB on front or side of press (clockwise increases pressure, counterclockwise decreases pressure). -
Page 19: Cycling
CYCLING Simultaneously actuate and maintain actuation of both CYCLE START buttons. The ram extends until it contacts the work, achieves tonnage and reverses or until the lower proximity switch (2PRS), if included, no longer senses the RAM GUIDE BAR, and reverses. Release of the CYCLE START buttons before contacting work or making lower proximity switch (2PRS) retracts the ram to its upper stop position. - Page 21 MAINTENANCE...

Page 32: Relief Valve Operation
RELIEF VALVE OPERATION At times, the relief valve is prevented from satisfactorily operating by the presence of lint, pipe scale, or foreign matter. This may cause fluctuations of pressure or pressure failure. Quite often, this condition can be corrected by starting the pump, loosening the relief Valve Locknut, then turning the Relief Valve Knob counter-clockwise. - Page 33 NOTE When hydraulic lines and fittings have been taken loose or replaced, care must be taken to assure all lines have been securely tightened to prevent leaks and ingestion of air into the system which would cause permanent damage to the unit. NOTE When components have been removed, some additional cycling may be required to ensure the...
