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 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 engines or their components caused primarily by improperly
securing loads, overloading, off-centered loads, use on other than
•
Inspect the engine stand before each use. Do not use the
engine stand if it is damaged, altered, modified, in poor
condition, leaking hydraulic fluid, or has loose or missing
hardware or components. Take corrective action before using
the engine stand.
•
Do not use the engine stand beyond its rated capacity. The
maximum capacity (6000 lbs.) is determined at a point where
the center of the engine is located no more than 13" from the
mounting hub surface. The engine stand is equipped with
a universal adapter that bolts to the mounting hub surface.
Center lines of engines weighing 5000 lbs. can be mounted no
more than 20" from the mounting hub surface and center lines
of engines weighing 4000 lbs. can be mounted no more than
25" from the mounting hub surface.
•
Use only on a hard level surface.
•
Wear approved eye protection.
•
Assure load is centered and secured to mounting adapters.
Consult the engine manufacturer for the proper engine
mounting hole locations.
•
Use only grade 8 bolts in all adapter and engine mounting
applications. Before handling and/or starting repairs, make sure
all hardware is tight and secure.
1.
This engine stand is equipped with a universal adapter which
can be configured to fit certain engines or certain optional engine
adapters. Determine the correct adapter for the engine you are
working on and tighten all hardware that attaches the adapter to
the engine stand's mounting hub.
2.
Sometimes air gets trapped in the hydraulic jack that controls
the angle of the mounting hub. An air bound hydraulic system feels
spongy when pumped and sometimes the jack will not pump in full
incremental strokes.

•
Threaded holes in adapters and engine blocks must be clean
and not damaged to insure thread engagement. A bolt thread
engagement must be equal to 1-1/2 times the bolt thread
diameter in order to maintain strength requirements.
•
Lock the rotating gear drive by engaging the crank handle with
the locking fork before applying a load to the engine stand and
working on the engine.
•
Avoid unsafe, off-balance loads by aligning the engine's center
of balance (rotational axis of the engine) with the rotational axis
of the engine stand's gear drive shaft. The center of balance
is generally a few inches above the crankshaft. The alignment
should not be off more than two inches. Consult the engine
manufacturer to determine the exact center of balance.
•
Keep body from underneath engine when being lifted or
suspended.
•
The engine stand's hydraulic jack is only used to gain engine
clearance when rotating the engine. Keep the jack at its lowest
possible position when working on an engine in order to avoid
tipping. Always release the jack slowly and carefully when
lowering a load.
•
No alterations should be made to this product.
•
Only attachments and/or adapters supplied by Norco shall be
used.
