Check Balance and Pressure Settings

Balance and pressure settings should be checked prior to start-
up as follows:
1. Start hydraulic pump.
NOTE: The hydraulic pump must be wired to an on/off switch
device. Pump rotation is clockwise when viewed above motor.
2. Make sure Direction Valve (See Figure 19 - located on front
of unit just above bottom product outlet) is functioning
properly. It is spring loaded and is moved up for up travel of
hydraulic cylinder and down for down travel.
3. Make sure the Balance Valve (See Figure 20 - located on the
front of the unit, just above the Direction Valve) is set in
closed position, which is fully clockwise. Valve is locked in
place with a 9/16" jam nut and adjusted with a 5/32" Allen
Head set screw. It maintains pressure on hydraulic cylinder
when hydraulic pump is off or in neutral position.
4. Check hydraulic pump pressure by moving hydraulic lift foot
away from Votator II unit and running cylinder in the full up,
dead head position. At this point, it should be adjusted for a
gauge reading of 300 to 400 psig at the pump.
5. The pump pressure control (See Figure 21, Item A) should be
set to approximately 4-1/2 turns open in the counterclockwise
direction from the closed position. This adjustment controls
the system pressure and is at maximum when the setscrew is
in the closed or full clockwise position. It is adjusted by a 3/
16" Allen Head set screw and locked by a 9/16" jam nut.
