Page 15: 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 16: Inching
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. Set the selector switch to JOG UP. -
Page 17: 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. 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 18: Cycling
CYCLING Simultaneously actuate and maintain actuation of both CYCLE START buttons. The ram extends until the lower proximity switch (2PRS) (if provided) no longer senses the RAM GUIDE BAR, and reverses or the press contacts the work, pressures up, and reverses (pressure reversal). Release of the CYCLE START buttons before lower proximity switch (2PRS) is made, retracts the ram to its upper stop position. - Page 20 MAINTENANCE...

RELIEF VALVE SERVICE... - Page 31 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.
