Material handling is inherently dangerous. To reduce
the likelihood of operator and bystander injury:
o Each person who might operate, use, or maintain this device must
Read and understand this manual in its entirety before operating,
using or performing maintenance on the scissor dock.
o DO NOT work on this device unless it is fully lowered and unloaded
and maintenance props are in place.
o Ensure that all safety and warning labels stay in place and are
legible. See the labels page in this manual.
o The scissor dock’s frame must be securely anchored in concrete.
See the installation instructions.
o Do not use the lift if any damage or unusual noise is observed.
o Always watch the platform and any load on it carefully when the lift
is in operation.
o Do not exceed a travel rate of two feet per second when moving
across the platform.
o The platform’s load ratings must be observed at all times. See the
operation instructions.
o Do no modify the lift without the express, written authorization of
Vestil. Unauthorized modifications might make the scissor lift
unsafe to use.
o DO NOT attempt to repair this scissor lift or perform maintenance on
it unless you are trained and authorized to do so.
o Do not use brake fluid or jack oils in the hydraulic system. If oil is
needed, use an anti-wear hydraulic oil with a viscosity grade of
150 SUS at 100°F, (ISO 32 cSt @ 40°C), or Dexron transmission fluid.
o Use only replacement parts either supplied or approved by the
manufacturer.

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 curr ent r eq uir eme nts . Re fe r to the l abe ls

♦ 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.

5.) Unusual noise or binding, or evidence thereof.
6.) Proper functioning of all limit switches, including those on the perimeter pinch point guard.
(B) Inspect monthly for:
1.) The oil level. Oil should be 1½” to 2” below the reservoir’s fill hole with the lift fully lowered.
See below for the hydraulic 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.) Damage or deformity of the bridge plates (including the hinge) and the handrails.
9.) Unusual noises or movement during operation.
10.) All the information, safety, and warning labels being in place and in good condition.
11.) The need to clean off dirt and debris.
12.) Grease all pivot points.
(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.

OPERATION INSTRUCTIONS – WL-100
The Occupational Safety and Health Administration (OSHA) incorporated Commercial Standard CS202-56 into its
mass of regulation [29 CFR 1910.6(j)(1)], which instituted design and performance requirements on Dock Leveling
Devices. However, the Dept. of Commerce (DoC) withdrew CS202-56 in 1980 and replaced it with ANSI MH30.1-2000.
The DoC also recommends ANSI MH29.1 as a source of instructions about industrial scissor lift operation. MH29.1 is the
appropriate choice in this case, because our WL-100 series of products are industrial scissor tables.
Safe operation is the responsibility of the operator according to ANSI MH29.1, Section 5. In addition to
the instructions that appear in this manual, ALL end-users of this product should refer to ANSI MH29.1 for information
regarding owner/operator responsibilities for safe operation, care, and maintenance. To reduce the likelihood that
personal injuries might occur as a result of using this product, each person who might install, use, or maintain this
product must understand and follow these recommendations:
Do not exceed the maximum rated load (capacity). Permanent damage to the lift or injury to personnel could
result from exceeding the listed capacity.
Keep all personnel clear of the scissor dock when it is in operation.
Never use the scissor dock 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.
Check the operation of the perimeter pinch point guards daily. Do not use the lift if the aluminum frame bars of
the guard are bent or if the circuit does not function.
DO NOT use the lift unless all labels are readable. Contact Vestil for replacement labels as necessary.
The standard model scissor dock is suitable for use indoors or outdoors in most industrial and commercial
locations. It is intended to be used to raise and lower material handlers such as fork trucks and pallet jacks to allow
freight to be loaded and unloaded from semi trailers.
Keep all personnel clear of the lift when it is in operation. Be certain no part of any person or object is under
any part of the lift before lowering the platform.
Loading:
The load rating, in pounds, is shown on the machine dataplate located on the bevel of the bridge plate end of the
platform. It indicates the net capacity of the scissor dock with a static load that is centered and evenly distributed on
the platform.
