INSTALLATION NOTES WL-100
Review these requirements and procedures before installing the lift.
Contact the factory for answers to any questions that remain after reading this manual or for assistance if you
encounter difficulties during installation.
The standard model dock scissor lift is suitable for use outdoors in most industrial and commercial location
s.
-------
------------------------------------------------------------------------------------------------
Installation notes:
All pit and cement work, curb angles, bumper posts, conduit, and electrical installations, as well as the
mater
ials for the same, are the responsibility of the installer or building owner.
For a pit installation: a minimum 2” conduit installed in the pit floor or wall is recommended for allowing th
e
hose and w
ire access to the lift, and a drain should be installed.
Five minimum 18 AWG wires (or an appropriate hard service cable) are required betw
een the power unit’s
control enclosure and th
e lift’s frame. These wires, the power unit’s disconnect, and the branch circui
t
overcurrent and short-circuit prote
ction are the responsibility of the installer or building ow
ner.
The installation must be made so that it complies with all the regulations applicable to the dock, the lift, and their
locat
ion. The installer or building owner must verify that the supplied equipment is installed so it will
be suited to
the envir
onment in which it will be used, and it must be mounted onto, and anchored into, suitable concrete.
An architectural review of the planned installation is recommended.
The installation of the dock lift must be performed by suitably trained personnel with access to the
appropriate
equipment. The electrical aspect
s of the installation should be performed by an electric
ian.
-------
------------------------------------------------------------------------------------------------
Installation will require the following tools and equipment:
o A lifting boom with rigging, a fork truck with adequate fork length and capacity, or some other appropriate
hoisting means to remove the lift from the freight truck when it arrives and to set the lift into place. The models’
weights can vary from 2,800 – 6,700 pounds.
o Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s
architect or facility engineer to determine the best size and type of hardware with which to anchor the lift to the
dock approach.
o 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.
-------------------------------------------------------------------------------------------------------
Do not work underneath the platform unless the maintenance props are installed in the frame.
The dock lift must be adequately anchored into the concrete at each corner of its frame.
If the supply voltage installed for the lift is different from that originally specified for the order, the
connections of the motor leads and the control transformer’s primary wires must be changed. Consult the
electrical diagrams in this manual.
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.

INSTALLATION INSTRUCTIONS WL-100
1. For pit-mounted units, che
ck that the pit conforms to the pit diagram.
Note: If the unit is to be placed into a pit, the required electrical and hydraulic connections to the dock lift should
be made before it is set
into place.
2. Mount the p
ower unit in the desired location. The standard 8’ hose will allow th
e power unit to be mounted
im
mediately adjacent to the lift. For mounting in other locations, a longer hose will be required. (Use ½” SAE
100R2 2-wire hydraulic hose with a 3,000 psi working pressure rati
ng.)
3. Using
an appropriate wiring method, connect the power supply to the power unit’s mot
or relay. Verify that the
mot
or supply voltage is the same as that shown on the machine dataplate (located on the middle of the ri
ght
platfo
rm side). Also verify that the correct control transformer primary leads are connected to the po
wer supply
at the mot
or relay’s termin
als.
4. Remo
ve all steel strapping and shipping materials from the lift. Do not remove the lifting ta
bs.
5. Use riggin
g to pick up the unit at the two lifting tabs (one on each end of the platform) and move th
e lift into
place. Note: If the lift is being pit-mounted, guide the hose and the wires or cable into the pit (such as when a pit
conduit is present) when lowering it. Use care to avoid damage to the lift’s internal electrical and hydraulic
components from the underside. Remove the lifting ta
bs.
6. Connect the
½” hydraulic hose between
the power unit and the lift’s frame.
Note: First, either flush or blow out the hose and fittings if any contaminants are observed inside them.
7. Install a ju
mper wire from terminal #3 to terminal #4 in the power unit’s control enclosure. Verify that the
overload relay setting matches the motor’s full-load amperage at the selected supply
voltage.
8. Use the pend
ant control to raise the platform just high enough to allow the table’s safety maintenance props to be
placed into the frame. Use the manual valve to lower the platform so the leg set rests on the props. (Push down,
turn the knob CCW, and release it to open the lowering valve. Push down and turn CW to cl
ose it.)
9. Remove the jumper wire between terminal #3 an
d termin
al #4.
10. At both the li
ft’s frame junction box and the power unit’s control enclosure, connect the five wires (inc
luding the
ground
ing wire) to the limit switch and toe guard circuit wires. See the electrical diagram in this manual
.
11. Close
and secure the control enclosure door an
d put the plastic cover over the power unit.
12. Cut and remove the
plastic ties that hold the aluminum toe guard strips up during shipping. Verify th
at all the
strip
s drop down and move freely, and that the switch in the middle of each strip is not actu
ated.
13. Raise the platform to
a height of 60”, measured from the bottom of the frame. Adjust the upper limit switch arm
(mounted on the non bridge-end of the frame) so that the motor turns off at th
at height.
14. Bleed the cylinders following the air bleed procedure at the botto
m of the “Power Unit Operation” page.
Afterward, remove the maintenance props and lower the platform using the pendant control. Hold the “DOWN”
pushbutton for several seconds after t
he platform is lowered so that any air in the hose will be able to more easily
migrate to th
e reservoir.
15. While lowere
d, check the platform for proper lowered height, or that it is flus
h with the ground if pit mounted.
16. Rais
e the lift, install the maintenance props,
and lower the leg set onto them once again.
17.
Anchor the frame to the floor through each of the two 13/16” holes located near each frame co
rner.
18. Shim and/or grout under t
he full
length of the frame sides.
19. Remove the maintenance props and operate the lift through several full up/down cycles. Verify that the upper
travel limit switch (mounted in the frame) and th
e toe guard switches (around the perimeter of the platform)
function properly.
20. Check the hy
draulic oil level. It should be filled to within 3” of the top of the reservoir. If oil is need
ed, use an
anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F (ISO 32 at 40°C) or a non-synthetic automatic
tra
nsmission flui
d.
21. Clean up any debri
s or spilled oil, and verify that all of the warning and safety labels are inta
ct.
