BEFORE USING THIS DEVICE, READ THIS MANUAL COMPLETELY
AND THOROUGHLY, UNDERSTAND ITS OPERATING PROCEDURES,
SAFETY WARNINGS AND MAINTENANCE REQUIREMENTS. FAILURE
TO DO SO COULD CAUSE ACCIDENTS RESULTING IN SERIOUS OR
FATAL PERSONAL INJURY AND/OR PROPERTY DAMAGE.
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 equipment
who are careful, competent, trained, and qualied in the safe operation
of the equipment and its proper use. Examples of hazards are dropping,
tipping, or slipping of motor vehicles or their components caused primarily
by improperly securing loads, overloading, off-centered loads, use on other
than hard level surfaces, and using equipment for a purpose for which it
was not designed.
It is the responsibility of the owner to make sure all personnel read this
manual prior to using this device. It is also the responsibility of the device
owner to keep this manual intact and in a convenient location for all to see
and read. If the manual is lost or not legible, contact Norco Industries, Inc.
for a free replacement. If the operator is not uent in English, the product
and safety instructions shall be read to and discussed with the operator in
the operator’s native language by the purchaser/ owner or his designee,
making sure that the operator comprehends its contents.
WARRANTY
This product is covered by a Limited Lifetime Warranty. For details see the
back cover of Norco’s product catalog.

WARNING
Inspect the engine stand before each use. Do not use if damaged,•
altered, modied or in poor condition, or has loose or missing hardware
or components. Take corrective action before using the engine stand.
Do not exceed rated capacity.•
Use only on a hard level surface.•
Consult engine manufacturer for proper mounting locations.•
Assure load is centered, balanced and secured to the mounting attachments.•
Mount the engine so its weight is balanced within one inch of the• stand’s rotational axis.
Only use the engine mounting plate and four adapter arms that• accompany the model 78125 engine stand when mounting engine
stands weighing 1,250 pounds or less.
Use grade 5, metric grade 8.8 (or better) cap screws for all mounting hardware.•
Threaded holes in adapters and engine blocks must be clean and• not damaged to insure thread engagement. A bolt or screw thread
engagement must be equal to 1-1/2 times the bolt or screw thread
diameter in order to maintain strength requirements.
Always move the stand slowly to avoid tipping of load.•
Rotate engine slowly to avoid jerking or movement of the engine which• could cause the mounting hardware to loosen.
Do not alter or modify the stand.•
Only attachments and/or adapters supplied by Norco shall be used.•
Never work under any load that is mounted to this stand.•
