Operation
WARNING
To reduce the risk of serious injury, including pinch-
ing or amputating your fingers, or splashing fluid in
the eyes or on the skin, always follow these pre-
cautions when using the elevator.
1. Relieve the air and the fluid pressure in the
pump before raising the pump to prevent
unexpected cycling of the pump.
2. Keep your fingers away from the top of the
drum and the bottom of the drum cover when
lowering the pump into the drum. Grasp the
pump bracket or pump motor when guiding the
pump into the drum.
3. Never use the elevator to lift a pump which
weighs more than 100 lb (45 kg). The elevator
may not be able to hold up a heavier pump,
and the pump could drop unexpectedly, caus-
ing personal injury as well as property damage.
4. Keep the restrictor valve in the restricted
position to avoid excessive speed when raising
the elevator.
Adjusting the Elevator Speed
Before regular operation of the elevator, check the
elevator speed.
1. Loosen the locknut (301) of the restrictor
valve (114) located at the top of the elevator. Turn
the adjusting needle (304) fully clockwise to de-
crease speed. See Fig. 2.
2. Connect the air line to the elevator pin fitting.
Slowly turn the adjusting needle (304) counter-
clockwise to raise the pump. When adequate
speed is obtained, tighten the locknut (301).
Raising and Lowering the Pump
1. With the elevator speed adjusted, connect the air
line coupler to the elevator pin fitting (108). The
pump will rise. See page 3.

2. Leave the air line connected to the elevator while it
is in the raised position.
3. Position a drum against the base of the elevator.
4. Disconnect the air line coupler; the pump will
lower. Check and adjust the elevator speed, if
necessary. See the section to the left.
5. As the pump is lowered, place your hands on top
of the drum cover or on the pump air motor to
guide the pump into the drum.
Changing Drums
1. Shut off the air supply to the pump and relieve all
air and fluid pressure.
2. Raise the pump, leaving the air line connected,
and change drums.
Shutdown
1. Never leave the elevator in the raised position
when not in use. Shut off the air supply to lower
the elevator.
2. For overnight shutdown or longer, and before
servicing the elevator, pump, or any system com-
ponents, disconnect the air line coupler from the
elevator pin fitting. Relieve all air and fluid pressure
in the pump and system.
3. If possible, keep the pump submerged in lubricant
to avoid contaminating the system. If that is not
possible, lower the pump into a clean, empty drum.
