To avoid serious injury or death, read this manual carefully before operating this unit. Call customer
service at the numbers and address printed on the back cover of this manual if you have any questions.
Failure to understand and obey safety instructions may result in unsafe or improper use of this
product.
1. Use the Wireless Portable Lift System only on hard, level surfaces. Lifting on other than hard
surfaces with a slope of more than 3 degrees (5% grade) can result in lift instability and
possible loss of load.
2. DO NOT raise / lower one side of a vehicle.
3. DO NOT use the Wireless Portable Lift System to raise a vehicle by the frame or structural
member. Only use the wheels of the vehicle to lift with the lift system.
4. DO NOT raise one end of a vehicle if the opposite end is supported by stands.
5. DO NOT use the Wireless Portable Lift System in conjunction with any other equipment used
to raise a vehicle.
6. Lift only on same axle. Product is to be used only in sets of 2, 4 or 6 units, not as a single unit.
7. DO NOT place feet or any part of body between lift frame base and carriage. Personnel injury
can occur.
8. DO NOT place hands, other parts of body, or clothing between carriage slide pads and the
upright rails the carriage slides on vertically. These are potential pinch points that can injury
hands and fingers or possible grab clothing that can cause personal injury.
9. DO NOT use blocks, non-factory supplied adapters or cribbing devices with this lift.
10. Maximum capacity is listed on the ID decal. Do not use the lift as a stand to support more than
maximum capacity. DO NOT overload.

12. No alterations shall be made to this product.
13. NEVER stand under the load or vehicle when it is being lifted or lowered.
14. NEVER stand either in or on the vehicle when it is being lifted or lowered.
15. DO NOT use the hoisting equipment to reach a lifted vehicle or to reach any part of the
vehicle.
16. Keep both the material and the surrounding area clean.
17. Before lowering a raised vehicle make sure there are no obstructions under the vehicle and the
lift carriages of the Wireless Portable Lift System.
18. Always keep the covers closed on the lifts.
19. DO NOT attempt to move the load horizontally when the vehicle is raised on the Wireless
Portable Lift System by any means.
20. Whenever the lifted vehicle is propped up and the lifting units are removed, use only the stands
intended for this purpose.
21. It is recommended that proper stands be used when the vehicle will be left in the raised
3
position for extended periods of time.
22. Do not use lifts outdoors when wind speeds exceed 20 mph.
23. NEVER start the vehicle motor when the vehicle is supported by the lifts or stands. Only start
engine when vehicle is standing on the ground.
24. Make sure there is adequate clearance above highest point of vehicle before lifting. Lift raises
67”.

Operating Instructions
Using the WPLS Lift System to Raise a Vehicle
This section discusses the appropriate and safe methods for using the WPLS Wireless Portable Lift System to raise
and lower a vehicle.
WARNING
Using the WPLS Lift System to raise a vehicle requires several steps that must be
followed each and every time the lift system is used:
1. Inspect each lift for signs of wear or damage.
2. Transport the lifts to the work area.
3. Locate appropriate support stands, if needed.
4. Prepare the surrounding area before using the lift system.
5. Identify vehicle axles to lift, examine the tires, and prepare the vehicle.
6. Raise the vehicle.
7. Lower the vehicle to the Ground.
Each of these steps is discussed in detail in the following sections. Failure to follow
all of these instructions can lead to serious injury or death.
1. Inspect the Lift for Signs of Wear or Damage
Before each use, you should inspect the lift for any visible signs of wear or damage. See the “Structural
Inspection” section for details about how to inspect the lift. WARNING! If you see any signs of wear or damage,
or if there is any indication that the lift is not performing normally, immediately take it out of service and call
customer service at 800-821-7320 or 816-233-6121. NEVER use a lift that appears damaged in any way.
2. Transport the Lifts to the Work Area
Transport the lift to the work area by either (a) wheeling it or (b) lifting and transporting it using the provided
forklift pockets. The lift can be wheeled to the work area over smooth surfaces and short distances—transport the
lifts if traveling over longer distances and/or rough surfaces. WARNING! Jolting caused by the wheels catching
on uneven surfaces can cause physical strain and personal injury.
See the “Handle Operation” section for details on how to properly maneuver the lift unit.
3. Locate Appropriate Support Stands, if needed
Gray Manufacturing Company, Inc. recommends the use of appropriate support stands when the vehicle to be
lifted is to be left elevated for an extended amount of time. Gray Manufacturing Company, Inc. manufactures
support stands that are made specifically for high rise supporting.
