Figure 2 – Mount the Lift Securely
Please read and follow this
instruction manual, including
all safety instructions and
precautions, carefully and
completely.
INSTALLATION INSTRUCTIONS
Preparation
1. Before you start to install the lift, check for local codes
and ordinances that may apply. It is your responsibility to
obtain any necessary permits.
2. Read all of these installation instructions carefully.
Be sure to read and understand all of the warnings!
3. If your unit is designed to be installed in a pit, check the
pit before you start to install the lift. Measure the length and
width of the lift table, then measure the pit, and be sure the
pit allows adequate clearance, there is a 3/4'' or less gap
between the platform and the pit wall all the way around. Does
the pit have 90° angles at each corner? To check, measure
across the opposite corners of the pit. The measurement
on each diagonal should be the same, within 1/2 inch. The
walls of the pit should be vertical. Check with a carpenter's
square.
4. If the power unit will be mounted away from the lift
("external power unit"), check the mounting arrangement
for the power unit. The power unit must be sheltered from
the weather. It should be mounted within 30 feet of the lift to
minimize the pressure drop in the hydraulic system. Be sure
the hydraulic lines have been installed properly.
Protect the power unit from rain or moisture.
If the electrical parts in the power unit get wet,
workers may be hurt by electrical shock. The
electrical parts may fail if they are wet.
The electric motor in the lift can create sparks.
Do not install the power unit in an area where
flammable gases may be present.

WARNING!
WARNING!
5. If the power unit is mounted within the lift ("internal power
unit"), you will need these tools:
• A crane or lift truck that can lift the unit safely.
• Shims and lag bolts – see the pit plan if the lift will be
mounted in a pit. Concrete grout may be required, see
figure 2.
• A masonry drill and bit to drill the holes for the lag bolts.
• A power supply with the specified voltage, including fuses
or circuit breakers as specified in Figures 16 through 20.
If the power unit will be mounted away from the lift ("external
power unit"), you will also need:
• A compressed air source for clearing the hydraulic lines.
• Extra hydraulic oil for flushing the underground lines and
refilling the tank. See Table 1 for the oil specifications.
Positioning the Lift
6. Remove the shipping material and unskid the lift. On the
front of this manual, write down the model number, serial
number, and date the lift is placed in service. You can find
the model number and serial number on the name plate as
shown in Figure 10. You cannot see the name plate without
lifting the table top. Use an overhead crane or fork truck to
do this. Lift the hinged end of the table top.
7. Move the lift into position, supporting the base of the lift.
Install the lift as shown in Figure 2. Unless the lift is mounted
on casters, lag the lift to the floor.
Do not hang the lift from the table top. This can
damage the lift.
WARNING!
If the lift is mounted on an unstable surface, it may
tip over when it is in use. You may be hurt, and the
lift and load may be damaged.
Use lag bolts to hold
the unit down
(unless it is mounted
on casters)
Mount the lift on a rm,
level surface
After leveling, grout the area
under each roller track, leg
set, hinged end, platform roll
over supports and down stops.
Lag plates
If necessary, insert shims
to level the lift
CAUTION!
