INSTALLATION INSTRUCTIONS – MODEL ZLTT

Review this entire page before installing the lift. Consult the factory

in the event there are any questions or problems at the time of installation.

The lift-and-tilt table must be removed from the shipping wood and securely anchored to the floor before use!

• The standard model ground-clearance lift-and-tilt table is suitable for use indoors in most industrial locations
and many commercial locations, and is typically provided as a turnkey system. Anchoring the unit to the
floor and an electrical supply to the remote power unit is typically all that is required for installation.

• Modifications or additions to the lift without prior manufacturer’s authorization may void the lift’s warranty
(see ANSI MH29.1, Safety Requirements for Scissor Lifts, section 12.6.) The addition of ancillary equipment
to the platform may necessitate that its load capacity be reduced.

• The installation must be made so that it complies with all the regulations applicable to the machine and its
location. The end-user must verify that the supplied equipment is installed so it will be suited to the
environment in which it will be used.

• Installation must be performed by suitably trained personnel with access to the appropriate equipment. The
electrical aspects of the installation should be performed by an electrician.

----------------------------------------------------------------------------------------

For a standard installation you will need the following:

1. A smooth, level concrete surface on which to mount the lift.

2. A fork truck with fork extensions, or a hoisting means to unload the lift and its power unit from the freight
truck and set it into place.
Caution: To prevent damage to the unit, careful consideration must be used when choosing a lifting
method.

Note: The unit must only be lifted when in the level and fully lowered position and fully supported
underneath, across its width.

3. Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, steel shims, and tools to square up the
frame before anchoring. Consult the building’s architect or facility engineer to determine the best size and
type of hardware with which to anchor the machine to the floor.

4. A power supply circuit and disconnect matching the motor voltage and current requirements. Refer to the
labels on the control enclosure and to the electrical section in this manual for more information. The end­user is responsible for supplying the branch circuit’s required overcurrent and short-circuit protection.

---------------------------------------

1. Move the lift into place with forks placed under the unit’s frame from the side. Use fork extensions if
necessary. Use care to avoid damage to the electrical and hydraulic components mounted to the lift.

Note: The lift must only be lifted when in the lowered position and fully supported underneath, across its
width.

2. Temporarily connect the power supply to the pigtail cord supplied with the table, and raise the platform so
the table’s safety maintenance props can be utilized. Lower the platform so the unit is supported by the
props.

3. Square the frame to ensure the frame sides are parallel and square with each other.

4. Use appropriate concrete fasteners to anchor the lift’s frame to the floor, at each corner.

5. Shim and/or grout under the full length of the frame sides.

6. Make permanent connection to the power supply, using an appropriate wiring method.

7. Raise and tilt the unit through several full up/down cycles. Verify that the upper travel limit switches
(lifting and tilting) and the toe guard switch function properly.

8. Check the hydraulic oil level. It should be filled to within 1” to 1½” of the reservoir’s fill hole. If oil is
needed, use an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F (ISO 32 at 40°C) or a non­synthetic automatic transmission fluid.

9. Clean up any debris or spilled oil, and verify that all of the warning and safety labels are intact.

OPERATION INSTRUCTIONS – MODEL ZLTT

o Ensure that all employees involved in the operation of this lift-and-tilt understand and

follow these instructions!

Loading:

The load rating, in pounds, is shown on the machine dataplate located on the torsion rod at

the operator’s right side corner. It indicates the net capacity of the ZLTT with the load
centered and evenly distributed.

Warning: The vertical center-of-gravity of the load on the platform should be at least 12”

inside the main box pivot point when the platform is tilted.

Note: The addition of any ancillary equipment to the platform by third parties must be

taken into account when determining the maximum working load.

Warning: Do not exceed the platform’s load ratings. Permanent damage to the equipment

or injury to personnel could result from exceeding the listed capacity.

Operation:

Inspect the perimeter pinch point guards’ operation daily.
Warning: Keep all personnel clear of the machine when it is in operation. Be certain no part

of any person or object is under any part of the platform before lowering the unit.
Caution: Always carefully watch the platform and any load on it when it is in operation.
The ground-clearance lift-and-tilt table is furnished with either a constant-pressure (dead-

man style) pushbutton (standard) or dual twin foot switch (optional) control.
Pressing either the “LIFT RAISE” or “TILT RAISE” pushbutton or foot switch will turn on the

power unit to raise or tilt the platform, respectively. The platform will move only while

the control is pressed. Upon releasing the control, the platform will stop and hold its

position.
Pressing the “LIFT LOWER” or “TILT LOWER” pushbutton or foot switch will energize the

corresponding lowering valve to allow the platform to descend by gravity (the motor

does not run). Again, releasing the control will stop the platform movement, and the

unit will hold its position.
Caution: Never use the lift if any damage or unusual noise is observed, if it is in need of

repairs, or if it seems to be malfunctioning. Notify your supervisor or maintenance

personnel if you notice anything out of the ordinary.
Ensure that all safety and warning labels stay in place and are legible. Refer to the labels

page in this manual.

ROUTINE MAINTENANCE & SAFETY CHECKS – ZLTT

o Warning: Care should be taken to identify all potential hazards and comply with

applicable safety procedures before beginning work.

o Warning: Raise the platform and install the maintenance props before beginning any

inspections or work on the unit.

o Only qualified individuals trained to understand mechanical devices and their associated

electrical and hydraulic circuits should attempt troubleshooting and repair of this
equipment.

(A) Before each use inspect for the following:

1.) Frayed wires.

2.) Oil leaks.

3.) Pinched or chafed hoses.

4.) Damage or structural deformation to the structural members, cylinder brackets, etc.

5.) Unusual noise or binding, or evidence thereof.

6.) Proper functioning of all limit switches, including those on the loading-side pinch point

guard or photoswitch.
(B) Inspect monthly for:

1.) The oil level. Oil should be 1½” to 2” below the reservoir’s fill hole with the lift in the

fully raised position. See below for oil specification.

2.) Worn or damaged hydraulic hoses and electrical wires.

3.) Pivot point wear.

4.) Rollers’ looseness and wear.

5.) Integrity of the retaining rings on all rollers and on all pivot point pins.

6.) The integrity of the frame anchor bolts, and for cracks in the concrete around them.

7.) Proper functioning of any hand- or foot-operated mechanisms.

8.) Unusual noises or movement during operation.

9.) All the information, safety, and warning labels being in place and in good condition.

10.) The need to clean off dirt and debris.
(C) Yearly inspection

The oil should be changed if the oil darkens, becomes gritty, or turns a milky color
(indicating the presence of water). Replace with an anti-wear hydraulic oil with a
viscosity grade of 150 SUS at 100°F, (ISO 32 at 40°C). Ex: AW 32 or HO 150 hydraulic oil,
or a non-synthetic transmission fluid. You may use a synthetic transmission fluid if you
flush the system with the synthetic fluid before filling the reservoir.
