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 qualified 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.

OPERATING INSTRUCTIONS
- Consult the vehicle or engine manufacturer for the engine’s center of gravity. The engine’s center of gravity will have to be aligned with the rotational axis of the engine stand’s mounting head assembly.
- Remove the clutch bell housing from the engine and secure any other engine parts that might be loose or hanging from the engine.
- Remove the adjustment knob from the side of the engine stand and extend the “T” base so that it is about 6” farther than the engine when the engine is mounted to the stand. are loosely connected to the mounting plate assembly. Fasten the four engine adapter arms to the engine using the proper bolt thread size and length. Remember to use grade 5, metric 8.8 bolts or better. Do not tighten the bolts.
- Align the rotational axis of the mounting plate assembly as close as possible to the engine’s center of gravity. Tighten the four bolts that secure the engine adapter arms to the engine and the bolts, flat washers and nuts that connect the other end of the engine adapter arms to the mounting plate assembly.
- Attach an engine lifting bar or sling to the engine and raise the engine with a shop crane or lifting device with a load capacity that can adequately handle the engine weight. Once the engine is lifted to the desired height, slowly push the engine with the mounting plate assembly pointing toward the drive shaft of the engine stand. Insert the stand’s drive shaft into the receiver on the mounting plate. Turn the stand’s gear box handle until the threaded holes in the drive shaft align with the holes in the mounting plate receiver. Once aligned, secure with the bolts and lockwashers provided.
- Make sure the setup is stable and slowly and carefully remove the shop crane or engine lifting device.
REMOVING ENGINES FROM THE MODEL 78125
- Attach an engine lifting bar or sling to the engine. Connect the bar or sling to a shop crane or lifting device and slowly lift the engine just enough to take pressure off the engine stand.

- Extend the base of the engine stand to a point where the distances between the two mounting plates will accept the engine, the length of two adapter arms assemblies and a couple extra inches of free play.
- Attach an engine lifting bar or sling to the engine and raise the engine with a shop crane or lifting device with a load capacity that can adequately handle the engine weight. Once the engine is lifted to the desired height, slowly position the engine between the mounting plates. Loosely attach four adapter arms assemblies to each side or end of the engine where the arms positioned as far apart as practical for greater supporting strength.
- Loosely attach the opposite ends of the adapter arm assemblies to their respective mounting plates with the flange nuts provided. Remember to position the arms in the slots of the mounting plates where the arms are positioned as far apart as practical.
- By raising and lowering the engine, position the engine’s center of balance within one inch of the engine stand’s rotational axis. After the engine and adapter arms are correctly positioned, Torque all mounting hardware to 75 foot pounds.
- Make sure the setup is stable and secure before removing the shop crane or lifting device.
REMOVING ENGINES FROM THE MODEL 78200
- Attach an engine lifting bar or sling to the engine. Connect the bar or sling to a shop crane or lifting device and slowly lift the engine just enough to take pressure off the engine stand.
