THE NATURE OF HAZARDOUS SITUATIONS

The use of portable automotive lifting and support 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 and understand all instructions before operating.
•  User and bystanders must wear eye protection that meets ANSI Z87.1 and OSHA standards.
•  Inspect the engine stand before each use. Do not use if damaged, altered, modified, in poor condition, or has loose or missing 

hardware or components. Take corrective action before using the engine stand.

•  Do not use beyond rated capacity.
•  Use only on hard level surface capable of supporting the load.
•  Make sure all mounting hardware is securely tightened and setup is stable before rotating engine.
•  Always use high strength SAE grade 8 bolts for mounting engine to mounting head fingers.
•  Make sure widest set of mounting head fingers are nearest the ground when mounting engine to stand.
•  Assure the load is centered, balanced and secured to the mounting head and fingers. The engine’s weight should be balanced within 

one inch of the mounting head’s rotational axis.

•  Adequately support the vehicle before starting repairs.
•  Never loosen mounting head bolts or engine mounting bolts unless engine is supported by a crane or hoist.
•  Only attachments and/or adapters supplied by NAPA shall be used.
•  Do not use stand to dolly or transport engine.
• 

Do not crawl under engine or place any part of your body under engine at any time.

•  Refer to engine manufacturer’s service manual for proper lifting points, mounting points and bolt sizes. Mounting bolts should be 

torqued at appropriate amount to maintain load.

•  Do not use (or modify) this product for any other purpose than that for which it was designed without consulting the manufacturer's 

authorized representative.

•  This product contains 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 warnings may result in serious or fatal personal injury and/or property damage.

CONSEQUENCES OF NOT AVOIDING HAZARDOUS SITUATIONS

Failure to read this manual completely and thoroughly, failure to understand its OPERATING INSTRUCTIONS, SAFETY WARNINGS, 
MAINTENANCE INSTRUCTIONS and comply with them, and failure to comply with the METHODS TO AVOID HAZARDOUS SITUATIONS could 
cause accidents resulting in serious or fatal personal injury and/or property damage.
