GENERAL RECOMMENDATIONS AND ADVICE
EVERY TIME A SAFETY HOIST IS SET UP FOR OPERATION YOU MUST:
1. REMEMBER THAT THE HOIST TRACK IS NOT A
LADDER! IF USED AS A LADDER INJURY MAY OCCUR.
2. THIS LADDER SHOULD NEVER BE USED TO
TRANSPORT A PERSON FROM ONE ELEVATION TO
ANOTHER!!
3. NEVER OPERATE HOIST IN WET WEATHER
CONDITIONS.
4. Check condition of the electric hoist before connecting the pendant and the power cords.
5. Inspect winch drum and cable assembly for obvious damage or misalignment. Inspect winch drum to make sure
that cable is wound smoothly with no crossovers. If there are any, use the pendant to run the hoist in reverse and
pull off enough cable to eliminate the crossovers. Then, with a leather glove, carefully use the pendant to wind the
cable back onto the drum to prevent cable kinking.
6. Inspect the pendant and power cables to make sure they are in good condition with no cuts or tears. Make sure
no oil or mud has gotten onto the connector assemblies which will cause the hoist to malfunction.
7. Test the brake. Put one bundle of shingles (or about 70 to 100 pounds) on the platform. Only lift it two or three
feet to make sure the brake is working properly, and then lower the load. Do this before trying to lift
a load heavier than the test load. Once you are certain the brake will hold, raise the load you are trying to lift up a
few feet. Stop raising the load and wait a minute to make sure the load does not slip.This will verify that the brake
is working properly for the full load weight.

Operator’s Manual EH-500 Electric Material Hoist
GENERAL SAFETY INSTRUCTIONS
The safety instructions and warnings in this section and throughout this manual must be read carefully before
assembling or operating the hoist. These safety instructions and warnings are not substitutes for routine accident
prevention measures which must also be immplemented to eliminate potential risks and hazards. Failure to obey
these safety warnings may result in injury to you or others, or damage to the hoist or other property.
A. UNPACKING YOUR HOIST
-When unpacking, carefully inspect for any damage that may have occured during transit.
DO NOT ASSEMBLE OR USE THE HOIST IF ANY PART OR PARTS ARE DAMAGED!!
Return the damaged part or parts to place of purchase for replacement.
B. SAFETY LABELS
-Observe all labels and instructions attached to the various parts of the hoist.
C. PROPER PARTS
-For your safety, use only attachments and accessories approved by the manufacturer for use with the
hoist. Using substitute parts will void the warranty.
D. SAFETY CHECK
- Check assembled parts (splice plates, bolts, engine mounting, pulleys, hoist cable, etc.) for proper
tightness and t before using the hoist, and during frequent periods of use, be certain the equipment
is in safe working condition. Recheck for bolt tightness after every 4 hours of operation.
E. TRANSPORTING
- To avoid damage, handle hoist component parts with care when transporting. Secure hoist to truck bed with
cord rope or bungee cord. Damaged parts MAY make hoist not SAFE to operate. NOTE: Transporting hoist
in the rain may cause damage to the electric motor. Cover electrical components with a plastic sheet and
inspect prior to use. See page 6 - HowTo Assemble Your Hoist.
F. BRACING YOUR HOIST
- Never place or operate the hoist on a slippery surface and make certain it is properly secured at
the base to prevent slippage or unexpected movement. Make sure the hoist is braced against a building
or solid surface at the correct angle as described herein.
G. HOUSEKEEPING
- Clear the area around the base of the hoist to avoid slipping, tripping, or falling against the hoist.
H. SECURING YOUR HOIST
- Secure track to the roof with a rope.Tie the rope to a rung or the peak and then secure other end of rope
to the building. Do not tie to the rail because the rope will interfere with the travel of the carriage.

ELEVATION TO ANOTHER!!!!
C. MAXIMUM CAPACITY
-THE MAXIMUM CAPACITY OF THE HOIST IS 500 POUNDS. DO NOT
OVERLOAD!!
D. WARNING
- Keep hands, feet, other body parts and clothing away from the track and moving or rotating parts of the
hoist when operating the hoist.
E. MOLTEN SUBSTANCES
- Do NOT use the hoist to lift buckets of hot asphalt or any other hot or liquid substance, unless contents are
in a closed and sealed container.

on the ground
- See page 4 for specications of included parts
and materials.
2. Lay the base track section on the ground with the
rung short-side facing down.
- Attach carriage stops at this time. NOTE:There are right
and left handed carriage stops.

FIGURE 9
11. Attach the thimble on the cable to the back of
the carriage using the 1/2 - 13 x 1.5 bolt washer
thimble washer nut.
SEE FIGURE 8.
12. You are now ready to lift the hoist into place
- WARNING:When setting up your hoist please take note
of all overhead obstructions and/or electrical wires. Select
a location that is free of trafc and pedestrians.
13. Lay the assembled hoist alongside the wall where
the hoist is to be used
14. Place hoist against building at the correct angle.
