OPERATION INSTRUCTIONS
• Consult ANSI MH29.1, Section12 for the owner’s / user’s responsibilities regarding the operation, care, and
maintenance of the scissor dock.
• Ensure that all employees involved in the operation of this lift understand and follow these instructions!
§ 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.
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.
When not fully lowered, the lift’s maximum single axle load is 60% of the rated capacity for side loading, and 75% for
end loading. (The hydraulic hose and bridge plates are at the lift’s “ends.”)
In the fully lowered position, cross-traffic loads must not exceed two times the platform’s load rating.
Do not exceed a rate of two feet per second when moving loads across the platform.
Note: The addition of any ancillary equipment to the scissor dock by third parties must be taken into account when
determining the maximum working load to be placed on the platform.
Warning: Do not exceed the scissor dock’s load ratings. Permanent damage to the lift 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 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.
Caution: Always carefully watch the platform and any load on it when the lift is in operation.
§ The scissor dock is furnished with a constant-pressure (dead-man style) pushbutton control on a coil cord.
•
Pressing the “UP” pushbutton will turn on the power unit to raise the platform. The platform will raise only while
the control is pressed. Upon releasing the control, the platform will stop and hold its position.
•
Pressing the “DOWN” pushbutton will energize the lowering valve to allow the platform to descend by gravity (the
motor does not run). Releasing the control button, or the operation of the pinch point guard, will stop the platform
movement and the unit will hold its position.
§
To lower the platform in the event of a malfunction or power outage, remove the power unit cover and locate the
colored, knurled knob on the end of the lowering valve. Be certain there are no obstructions or personnel under the
lift! Push the knob in, twist the knob counterclockwise 180°, and release it. When the platform has been lowered,
push the knob in again, twist the knob clockwise 180°, and release it.
Safety:
Warning: Do not exceed the scissor dock’s load ratings as indicated above.
Warning: Keep all personnel clear of the scissor dock when it is in operation.
Caution: 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 guard’s aluminum bars are
bent or if the circuit is not functional.
§ Ensure that all safety and warning labels stay in place and are legible. Refer to the labels page.
