LOADING INSTRUCTIONS

SEQUENCE OF OPERATION

The load capacity rating as inscribed on the
nameplate of your unit designates the net capacity,
assuming the load is centered. This capacity must
never be exceeded, as permanent damage or injury
may result.

INSTALLATION TOOLS REQUIRED

A fork truck or some means to lift the table.
An adequately-sized power circuit with the specified
voltage, including a disconnecting means with fuses
or a circuit breaker. See the electrical section and
refer to the NEC and local codes.

INSTALLATION

• Check local codes for requirements pertaining to

your application.

• Blow out any hoses that arrive unconnected in

order to remove any potential contamination.

• Set the machine in place with a fork truck, crane,

etc. (If it is to be pit-mounted, connect power to the
table and raise the platform before setting it into
the pit.)

This machine is furnished with a constant­pressure, or dead-main, style push-button control.
Pressing the "LIFT RAISE" button will turn on the
power unit and cause the table to lift straight up. It
will continue to more as long as you hold the button
or until the lift reaches its maximum raised height.
When the button is released, the platform stops and
holds at that particular height.

Pressing the "LIFT LOWER" button
energizes the lowering solenoid's coil and lowers
the platform at a controlled rate of descent. Upon
releasing the button, the platform stops and holds at
that height.

Pressing the "TILT RAISE" button turns on
the power unit and causes the platform to slide in
toward the center of the table and tilt at the same
time. It will continue to tilt until the either the operator
releases the button or the platform reaches its
maximum tilt angle. When the button is released,
the platform stops and holds its position.

Pressing the "TILT LOWER" button also turns
on the power unit and causes the platform to tilt
down toward the horizontal position until either the
button is released or the platform is lowered to the
horizontal position.

• Connect the proper power supply to the table
using personnel qualified to work with electricity.

• Raise the platform to its full raised height using the
push-button control. Install the maintenance props
(one on each side of the frame) and lower the
platform using the push-button control until it rests
on the maintenance props.

• Anchor the frame to the floor using 1/2" concrete
anchors adequate for the floor on which the table
is resting. Shim or grout under the frame sides so
that the entire length of each frame side is
supported.

• Operate the lift through several cycles, verifying
that the "platform raised," "platform tilted," and
"platform level" limit switches all work properly.
Verify the operating of the perimeter pinch point
(toe) safety guard.

• Clean up any spilled oil or debris.

OPERATOR TIPS

• Read and understand all warning labels on the lift
before operating it.

• Stand clear and to the side of the unit when it is
moving.

• Don't use the lift if you suspect it is in need of
repairs or if it is malfunctioning.

• Notify maintenance personnel in the event that
you notice anything out of the ordinary, such as
binding, odd pump noises, etc.

• Don't continue to press either of the "LIFT" buttons
if the platform doesn't move. Doing so could cause
damage to the pump or motor.
