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

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.
