Operation
Starting and Adjusting the Elevator
You must adjust the elevator to ensure that the cover
is supported by the drum.
Close all air regulators and air valves.
Open the main air bleed valve. Pull up on the air
control valve and let the elevator rise to its full
height. Normal operation requires only a few sec-
onds for air pressure to build up or exhaust, and to
start raising or lowering the elevator.
Set a full 200 liter (55 gal.) drum against the eleva-
tor base.
WARNING
MOVING PARTS HAZARD
Moving parts can pinch or amputate your
fingers. When the pump is operating and
when raising or lowering the elevator,
keep your fingers and hands away from the eleva-
tor, pump support, drum cover, and lip of the drum.
With your hands away from the drum and the cov-
er, push down on the air control valve and lower
the elevator until the cover rests on the lip of the
drum. The support clamp recesses must be tight
against the elevator riser tube.
5. Raise the elevator 1.4 in. (6.4 mm), then tighten
the support clamp screws. This ensures that the
cover rests on the drum lip when the elevator is in
the lowered position.
6. Before operation, ensure that all fasteners and
tube connections are tightened securely.
NOTE: To increase or decrease the operating speed of
the elevator, loosen the hex nut of the restrictor valve
and turn the valve needle either in or out.

tor.
