Installation
1. Place the unit in the desired location, making sure
to have adequate clearance for plumbing while the
unit is being raised or lowered. Overall height of
the unit when raised is 94” (2930 mm) See
Dimensions on page 8.
2. Level the base, using metal shims if necessary,
and bolt the unit to the floor using the mounting
holes provided in the elevator base.
3. If desired, the elevator base can be repositioned to
permit raising the pump from one drum, pivoting
180, and lowering it into another drum. See
Fig. 1. The support bracket swivels 360on the
elevator riser tube.
4. Loosen the elevator clamps and slide the support
bracket down over the elevator riser tube. See
Fig. 1. Temporarily position the bracket high
enough to permit mounting the pump, and loosely
clamp the bracket to the elevator riser tube.
5. Place the pump in the pump mounting bracket,
and secure it with the provided screws.
6. Loosen the elevator clamps, and slide the bracket
and pump down until the pump intake valve rests
on the floor.
7. Mount the elevator control valves on the wall, and
connect them to the elevator and air supply as
shown in the Parts Drawing on page 6. Connect
the fluid lines and air lines to the pump.

Operation
See Fig. 2. To raise the elevator, pull out on the knob
of the push-pull valve. The speed at which the elevator
raises can be adjusted at the restrictor valve: Loosen
the locknut, and turn the restrictor valve screw clock-
wise to decrease the speed, and counterclockwise to
increase the speed. Tighten the locknut when adjust-
ment is complete.
Position an opened drum of material against the eleva-
tor base. Loosen the setscrews holding the pump
mounting plates to support the bracket and position the
pump to line up with the drum opening. Tighten the
setscrews.
Push in on the knob of the push-pull valve, and guide
the pump into the drum.
Lubrication
Every two to six weeks, lubricate the elevator as
follows: Disconnect the air supply, and relieve the air
pressure; remove the elevator cap (19), and lubricate
the inner surface of the elevator riser tube (14) and
leather cup (10) with a few drops of lightweight,
high-grade motor oil. See Fig. 3.

Service
Elevator Service
To disassemble the elevator for service, unscrew and
remove the elevator riser tube (14), unscrew the piston
cap screw (20) from the piston body (11), and unscrew
the guide tube (13) from the piston body . Clean and
inspect all parts for wear or damage and reassemble,
using new parts as needed.
When reassembling, use plastic thread sealer on all
threads, and coat the inner surface of the riser tube
(14) with no. 2 lithium-base grease.
Push-Pull V alve Service
Worn washers, gaskets, or seals may cause valve
failure. Shut off the air supply and remove the valve
from the mounting bracket. Place the valve body in a
vise and disassemble. Replace any worn parts and
reassemble using the parts drawing on page 6 as a
guide.
