BEFORE USING THIS DEVICE, READ THIS MANUAL COMPLETELY AND THOROUGHLY UNDERSTAND ITS OPERATING 
PROCEDURES, SAFETY WARNINGS AND MAINTENANCE REQUIREMENTS.

It is the responsibility of the owner to make sure all personnel read this manual prior to using the device. It is also the responsibility of

THE NATURE OF HAZARDOUS SITUATIONS

The use of portable automotive lifting devices is subject to certain hazards that cannot be prevented by mechanical means, but only 
by the exercise of intelligence, care, and common sense. It is therefore essential to have owners and personnel involved in the use and 
operation of the equipment who are careful, competent, trained, and qualified in the safe operation of the equipment and its proper 
use. Examples of hazards are dropping, tipping or slipping of loads caused primarily by improperly secured loads, overloading, 
off-centered loads, use on other than hard level surfaces, and using equipment for a purpose for which it was not designed.

METHODS TO AVOID HAZARDOUS SITUATIONS

• Read, study, understand and follow all instructions before operating this device.
• Inspect the jack before each use. Do not use jack if damaged, altered, modified, in poor condition, leaking hydraulic fluid, or

unstable due to loose or missing components. Make corrections before using.

• Consult the vehicle manufacturer for the transmission's center of balance.
• Secure the transmission to the jack's saddle with the anchorage restraint system provided before raising or lowering

the transmission.

• Center load on saddle. Be sure setup is stable before working on vehicle.
• Never use a power tool to activate the saddle tilt screws. Operate by hand or socket wrench.
• Support the engine with a stand before unbolting the transmission from the engine.
• Wear eye protection that meets ANSI Z87.1 and OSHA standards (users and bystanders).
• Do not use jack beyond its rated capacity. Do not shock load.
• Use only on a hard level surface.
• Adequately support the vehicle before starting repairs.
• Use of this product is limited to the removal, installation and transportation in the lowered position, of transmissions, transfer

cases and transaxles.

• Do not use any adapters unless approved or supplied by Sunex.
• Always lower the jack slowly and carefully.
• Do not use (or modify) the product for any other purpose than that for which it was designed without consulting the

manufacturer's authorized representative.

• This product may contain one or more chemicals known to the State of California to cause cancer and birth defects or other

reproductive harm. 

Wash hands thoroughly after handling.

• Failure to heed these markings may result in serious or fatal personal injury and/or property damage.
