Poweramp PIT MOUNTED TRUCK SPECIALTY - Manual (Page 6)

I. RAISING THE LEVELER:
A. Press the "RAISE" button with a constant pressure until the leveler
reaches the proper height. The leveler will remain in this position until
the leveler is lowered.
II. LOWERING THE LEVELER:
A. Press the "LOWER" button with a constant pressure until the leveler
reaches the stored position.
III. SPECIAL NOTES OF INTEREST:
A. SPEED CONTROL - The lowering speed of the leveler can be
increased by turning the down speed control valve counter clockwise
(shown in diagram below), although this should have been preset
at the factory. The lowering speed can also be decreased by turning
the down speed control valve clockwise. The speed control
adjustment will have no effect on the upward travel speed of the
leveler.
B. POWER FAILURE - Should the power supply be disrupted while the
leveler is raised up the unit can be lowered to the stored position by
opening the needle valve (shown) with a 1/4" Allen wrench. The
needle valve must be closed again when the leveler is in the stored
position to assure proper operation of the unit once the power is
restored. DO NOT REMOVE THE ENTIRE NEEDLE VALVE
CARTRIDGE!
