15. WARNING: The warnings, precautions, and instructions discussed in this
manual cannot cover all possible conditions and situations that may occur. The
operator must understand that common sense and caution are factors, which

SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS

1. DO NOT EXCEED THE MAXIMUM LIFT CAPACITY (6,000 POUNDS AT 19”
ELEVATION) FOR THE CAR LIFT. Overloading the Car Lift could cause

personal injury and/or property damage. Caution: Be aware of dynamic loading!

If a weight falls onto the Car Lift, it may create for a brief instant an excess load,
which may result in damage to vehicle, Car Lift and/or personal injury.

2. OPERATION (RAISING OR LOWERING) OF THE CAR LIFT CAN BE

IMMEDIATELY STOPPED AT ANY TIME BY RELEASING PRESSURE ON THE

POWER SWITCH LOCATED ON THE MOTOR (part #1A).

(See Figure B, and Assy. Diagram A.)

3. DO NOT USE THE CAR LIFT ON ANY ASPHALT SURFACE. Make sure this
equipment is used on a dry, oil/grease free, flat, level, CONCRETE surface
capable of supporting the weight of the Car Lift, the vehicle being lifted, and
any additional tools and equipment. The concrete floor should have a minimum
thickness of 5”. The concrete must have a minimum strength of 4,000 PSI, and
should be aged at least 30 days prior to use. Do not use the Car Lift on concrete
expansion seams or on cracked, defective concrete.

4. ALWAYS EXAMINE THE CAR LIFT FOR STRUCTURAL CRACKS, BENDS,

DAMAGE TO THE HYDRAULIC HOSES AND ELECTRICAL WIRING, AND ANY
OTHER CONDITION THAT MAY AFFECT THE SAFE OPERATION OF THE
LIFT. Do not use the Car Lift even if minor damage appears.

5. MAKE SURE THE OIL TANK (part #12A) IS COMPLETELY FILLED WITH A
PREMIUM QUALITY HYDRAULIC OIL PRIOR TO OPERATING THE CAR LIFT.
(See Figure B, Assy. Diagram A, and the “INSPECTION, MAINTENANCE,
AND CLEANING” section.) Note: The hydraulic tank oil capacity is 1.5
gallons.

6. MAINTAIN A SAFE WORKING ENVIRONMENT. Keep the work area well lit.
Make sure there is adequate surrounding workspace. Always keep the work area
free of obstructions, grease, oil, trash, and other debris. Do not use the Car Lift
in areas near flammable chemicals, dusts, and vapors.

SKU 46604 PAGE 4 REV 04c, 05b, 10f

7. PRIOR TO BEGINNING A JOB, MAKE SURE THE SAFETY LOCK ASSEMBLY
(part #36B) AND ITS SAFETY CATCHES ARE IN THE PROPER POSITION.
NEVER work underneath a vehicle without using additional safety support

devices (i.e., jack stands) to support the vehicle.

(See Figure A, and Assy. Diagram B.)

8. ALWAYS KEEP HANDS, FINGERS, AND FEET AWAY FROM THE MOVING
PARTS OF THE CAR LIFT WHEN APPLYING OR RELEASING A LOAD.

Remain clear of the Car Lift when raising or lowering a vehicle.

9. USE EXTREME CAUTION WHEN APPLYING OR RELEASING A LOAD. Never
allow the load to suddenly release. Slowly and carefully apply and release the
load.

10. NEVER LEAVE THE CAR LIFT UNATTENDED WHEN THE LIFT IS UNDER
A LOAD. Whenever the Car Lift is under a load there is a very large amount
of force that has been stored in the Outside/Inside Scissors (parts #24B, #25B)
which must be controlled until the load is relaxed. (See Assy. Diagram B.)

11. BEFORE DRIVING A VEHICLE ONTO THE CAR LIFT, MAKE SURE THE LIFT
IS FULLY LOWERED. Before driving a vehicle onto the Car Lift, position the
Plates (part #42B) and Rubber Saddles (part #39B) inward. Do not hit or run
over the Plates and Rubber Saddles, as this could damage the vehicle. Make
sure the Car Lift is fully lowered before driving the vehicle off.

(See Figure A, and Assy. Diagram B.)

12. SHOULD ANY WEIGHT COMPONENT BE REMOVED FROM, OR ADDED TO
THE VEHICLE, USE A JACK STAND (not provided) TO SUPPORT THE OVER
BALANCED END DURING THE MAINTENANCE PROCEDURE. Do not

operate the Car Lift if the vehicle load tilts or binds during the up or down
movement. Always position the vehicle with the center of gravity midway
between the Rubber Saddles (part #39B). Avoid excessive rocking of the vehicle

while it is in the raised position. (See Figure A, and Assy. Diagram B.)

13. MAKE SURE TO READ AND UNDERSTAND ALL INSTRUCTIONS AND

SAFETY PRECAUTIONS AS OUTLINED IN THE MANUFACTURER’S
MANUAL FOR THE VEHICLE YOU ARE LIFTING. All four Rubber Saddles (part

#39B) of the Car Lift must be used when lifting a vehicle. Always use the vehicle
manufacturer’s recommended lifting points.

(See Figure A, and Assy. Diagram B.)

14. NEVER LIFT A VEHICLE WITH ANYONE INSIDE IT. Do not allow others in the
lift area while operating the Car Lift. Do not allow anyone to ride on the Car Lift
while it is being raised or lowered.

SKU 46604 PAGE 5 REV 05b

15. WHEN LIFTING A VEHICLE, RAISE THE RUBBER SADDLES (part #39B)

SLOWLY UNTIL THE RUBBER SADDLES SECURELY CONTACT THE

VEHICLE MANUFACTURER’S RECOMMENDED LIFTING POINTS. Then, lift

the vehicle to the desired working height. CAUTION: Always lift the vehicle high
enough for the Safety Lock Assembly (part #36B) to operate properly.

(See Figure A, and Assy. Diagram B.)

16. DO NOT USE THE CAR LIFT AS A PERMANENT STAND FOR A VEHICLE.
Use the Car Lift only while making repairs. Then, immediately remove the

vehicle from the Lift.

17. BEFORE LOWERING THE CAR LIFT, MAKE SURE TOOL TRAYS, STANDS,

AND ALL OTHER TOOLS AND EQUIPMENT ARE REMOVED FROM UNDER
THE VEHICLE.

18. MAKE SURE TO SQUEEZE AND HOLD THE BRAKE LEVER (part #13B) IN
BEFORE ATTEMPTING TO LOWER THE VEHICLE. Do not release pressure on
the Brake Lever until the Car Lift is completely lowered.

(See Figure B, and Assy. Diagram B.)

19. BEFORE REMOVING THE VEHICLE FROM THE CAR LIFT, MAKE SURE THE
PLATES (part #42B) AND RUBBER SADDLES (part #39B) ARE MOVED IN
TO PROVIDE AN UNOBSTRUCTED EXIT.

(See Figure A, and Assy. Diagram B.)

20. THERE IS A WARNING LABEL ATTACHED TO THE CAR LIFT. READ AND
FULLY UNDERSTAND THE CONTENTS OF THE WARNING LABEL. DO NOT
REMOVE THE WARNING LABEL FROM THE CAR LIFT.

21. GROUND THIS PRODUCT. This product requires the use of a UL approved, 220
Volt, grounded, 3-prong Electrical Power Plug (not provided). It is recommended
that only a qualified electrician install the Power Plug. Never remove the
grounding prong or modify the Power Plug in any way. Do not use adapter plugs
with this product. To comply with the National Electric Code, and to provide
additional protection from the risk of electrical shock, this product should only
be connected to a 220 Volt, 3-hole electrical outlet that is protected by a Ground
Fault Circuit Interrupter (GFCI). (See Figure B.)

22. IF AN EXTENSION CORD (not provided) IS USED, MAKE SURE TO USE

ONLY UL APPROVED CORDS HAVING THE CORRECT GAUGE AND
LENGTH. (See Chart, next page.)

23. NOT TO BE USED FOR AIRCRAFT PURPOSES.
