REPAIR & ADJUSTMENTS
7. Using a 1/4” allen wrench, adjust the minimum volume control adjusting screw.
Turn the screw clockwise to increase the amp reading or counterclockwise to de-
crease the amp reading. Make adjustments in 1/4 turn increments.
8. Use the allen wrench to prevent the adjustment screw from turning and tighten the
locknut.
9. Allow the pelletizer to operate normally for approximately one hour and check the
load amperage again. If necessary readjust the minimum volume control.
10.Stop the pelletizer operation and lock out electrical power to the pelletizer.
11.Disconnect the amp meter and close the electrical panel.
High Capacity Hydraulic Unit Set-up & Operation
Note: The following applies to tandem pump units only.
The hydraulic unit has a tandem Oilgear pump assembly driven at 1800 RPM by a 50
HP electric motor. One Oilgear pump delivers approx. 60 gallons of fluid per minute
and has a two pressure compensating control device. The other pump has a control de-
vice that lets you shift from an adjustable high flow set point (approx. 25 GPM) to an
adjustable low flow set point (approx. 18 GPM) simply by energizing a solenoid control.
The hydraulic unit has electric solenoid operated directional control valves and electric
solenoid operated decompression excess flow and dump valves.
The hydraulic unit has a return line heat exchanger (air-cooled) and return line contami-
nation filter.
Set-up The pump closest to the electric motor is the 60 gal high volume low pressure
compensating pump and is referenced as pump #1. The other pump (farthest from the
electric motor) is the solenoid controlled two volume (adjustable fixed displacement)
pump and is referenced as pump #2.
