OPERATING PROCEDURE

1. Assembling Drywall
Lift

Your 2300 series Drywall lift will arrive in three sections, the
Base, the Mast and the Cradle. Complete assembly will take
less than five minutes.

To assemble your lift, first
open the legs on the base
assembly to their operating
position. Make sure the
spring loaded plungers are
fully engaged and the legs
are locked securely into
position. Next, place the
mast assembly firmly into
the base. Make sure the
mast locating ring is firmly
seated onto the base locating post.

Finally, place the cradle assembly

onto the mast. Ensure that the cradle

is locked to the mast with the locking

pin and that it is facing the proper

direction.

2. Moving Lift to Work Area

(No Load)

The lift is normally moved to the job site by rolling on its 4”

casters using the steering handle. Note: Do not pull by the

load lifting cable.

3. Moving Lift in Work Area (With Load)

Although it is best to move the unit to the

job site unloaded, light loads may be

transported as long as the unit is rolled

on the casters on a level surface. Always

have the load in the lowest possible

position before moving the unit.

If it is necessary to move the unit with an

elevated load:

 Make sure the area is clear of ob-

structions

 Keep personnel away from the load and behind the

operator’s position

 Move the unit slowly, avoiding sudden jerky starts and stops

 Make sure the load is secure and properly balanced

CAUTION

If a load is being transported, it should be secured

to the cradle to avoid shifting.

WARNING

Moving the unit with elevated loads should be

contained to short distances; i.e., 10-15 feet/4-5

meters.

9. Back Up Brake

The 2300 series drywall lift is
outfitted with a “Back Up Brake.”
This stops the lift from rolling
backward when working up against
a wall or ceiling. To engage the
brake, simply press down on it with
your foot. This will release the
brake. The brake will now prevent
the lift from rolling backward. To
place the brake back into the
stored position, lift it up
with your foot until it
locks onto the rear leg.

10. Storing and Transporting the Lift

The 2300 series lift is designed for easy
transport. The unit is easily broken down
into three sections. All
three sections are easy to
carry. The main mast
even has a carrying handle
centrally located. Prior to
transporting the main
mast, attach the mast hold
down cable to prevent the
masts from extending un­intentionally.

4. Lifting and Lowering Loads

Use the winch to crank mast up or
down into the desired position.

Any unstable load must be balanced
and secured to the cradle prior to
lifting.

Turn winch crank clockwise to
elevate the load, while watching for overhead obstruc­tions. Turn winch handle counter clockwise
to lower the load.

Each handle is equipped with two
mounting positions. With the handles
mounted in the “standard” position, the
operator can raise and lower loads as
normal. With the handles mounted in the
“high speed” position, the operator can
raise and lower the lift in half the time.
