I. EVERY TIME SET UP INSTRUCTIONS
***IMPORTANT***
EVERY TIME A SAFETY HOIST IS SET UP FOR OPERATION:
1. CHECK OIL IN ENGINE AND GEAR BOX BEFORE STARTING ENGINE. REMEMBER
TO CHANGE THE OIL IN THE ENGINE AT LEAST EVERY 50 TO 100 HOURS
MAXIMUM.
2. INSPECT WINCH DRUM AND BRAKE ASSEMBLY FOR OBVIOUS DAMAGE OR
MISALGMENT. INSPECT WINCH DRUM TO MAKE SURE THAT CABLE IS WOUND
SMOOTHLY WITH NO CROSSOVERS. IF THERE ARE ANY, RELEASE THE BRAKE
AND PULL OFF ENOUGH CABLE TO ELIMINATE THE CROSSOVERS. THEN WITH A
LEATHER GLOVE, CAREFULLY WIND THE CABLE BACK ONTO THE DRUM TO
PREVENT CABLE KINKING.
3. INSPECT THE BRAKE BAND OR MULTISEGMENT BRAKE TO MAKE SURE IT’S IN
GOOD CONDITIONS WITH NO CUTS OR TEARS. MAKE SURE NO OIL OR MUD HAS
GOTTEN ONTO THE BRAKE ASSEMBLY WHICH WILL CAUSE THE BRAKE TO SLIP.
4. 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 CLEAN AND WORKING PROPERLY, AND THEN LOWER THE LOAD
SLOWLY. DO THIS AT LEAST SIX TIMES BEFORE TRYING TO LIFT A LOAD
HEAVIER THAN THE TEST LOAD. ONCE YOU ARE CERTAIN THE BRAKE WILL HOLD
THEN RAISE THE LOAD YOU ARE TRYING TO LIFT A FEW FEET.STOP RAISING
THE LOAD. WAIT A MINUTE TO MAKE SURE THE LOAD DOESN’T SLIP. THIS WILL
VERIFY THAT THE BRAKE IS WORKING PROPERLY FOR THE FULL LOAD WEIGHT.

II. GENERAL SAFETY INSRUCTIONS
A. These safety instructions and warnings are not substitutes for routine
prevention measures which must also be observed to avoid
potential risks and hazards. Failure to obey these safety warnings may
result in injury to you or others, or damage to the hoist.
1. WARNING… DO NOT USE OR PLACE THIS METAL HOIST IN ANY AREA
WHERE IT COULD COME IN CONTACT WITH ELECTICAL WIRING OR
OTHER HAZARDS CAUSING INJURY OR DEATH!!!
2. Avoid damage to Hoist operating parts by securing hoist to truck bed with cord
rope or bungee cord. Damaged parts MAY make hoist not SAFE to operate.
Note: Transporting hoist in rain may cause road oils to be deposited on brake
band and or brake pulley. Cover brake area with plastic sheet and inspect prior
to use. See Section III, How to Assemble your Hoist.
3. When unpacking a new Hoist, inspect parts carefully for any damage that may
have occurred during transport. DO NOT ASSEMBLE OR USE THE HOIST IF ANY
PARTS ARE DAMAGED!! Return the damaged part to the place of purchase for
replacement.
4. Observed all labels and instructions attached to various parts of the Hoist.
5. For Safe Operation use only parts, attachments and accessories
supplied by the Manufacturer for use with this Hoist. Using substitute
parts will void the Warranty.
6. Check assembled parts (splice plates, bolts, engine mounting, belts, pulleys,
hoist cable, etc.) for proper tightness and fit 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.
7. Never place the Hoist on a slippery, uneven or unstable surface. Make sure the
Hoist is properly braced against a building or solid abutment at the correct angle
as described herein. Base of hoist should be one (1) foot away from the building
for every (4) four feet of building height. Top of hoist must be tied off for safety
operation. Tie to rungs not side rails.
8. Keep the area around the base of the Hoist clear of debris to avoid
slipping, tripping or falling against the Hoist.
9. Handle fuel with care. It is extremely flammable and highly explosive
under certain conditions.
a. Never smoke or allow open flames or sparks to be present in the vicinity of
the when the fuel tank is being filled.

III.HOW TO ASSEMBLE YOUR HOIST
1. Unpack all parts of the hoist and lay them out on the ground.
MAJOR PARTS LIST
3-8ft. track sections with splice plate’s attached and 1-4ft. track section with splice
plates attached
1-VHPeak assembly
1-VHCarriage Flap (Flap Assembled on Carriage)
1-Carriage with 1/2” bolt, washers and lock nut (Bolt Assembled on Carriage) 1-
Steel base section with winch drum, brake, cable and drive belt
1-Brake release handle with hitch pin
1-Power Pack (engine bolted onmotor base)
Note that the engine is shipped without gas or oil. Oil needs to be added in the
crank case and the gear reduction unit, please refer to the instruction manual for
the engine for oil type and quantity.
2. Prepare hoist assembly by standing base section on its side with Brake Drum UP
and Brake spring away from assembler.
3. Slide an 8-ft. track section onto the base section with rung short side facing
towards assembler and secure each leg with two 3/8” carriage bolts and lock nuts.
Figure 1

Continue adding additional sections to reach the desired length of the hoist (See
Chart Page 7). The track sections are attached using the splice plates as noted
below with 3/8”x 3/4" carriage bolts and lock nuts. The splice plates must be
installed on the outside of the track section. See Figure 2
Figure'2'
4. Lay the hoist down on the ground with the brake spring towards the ground.
5. Slide the carriage onto the track section from the “Top” of hoist, with the flat
surface of the carriage facing away from the base section. See Figure 3

Figure 3
6. Slide the carriage along the track to base section so that the bumpers rest on the
base section. Make sure carriage slides smoothly on track.
7. Slide the peak assembly (CH-B) onto the end of the track and secure it with two
(2) 3/8”x 3/4" carriage bolts and lock nuts. See Figure 4
Figure 4
10. Slide the brake release handle over the brake bar and secure it with the hitch pin.
See Figure 5

11. Turn the hoist up on its side with brake drum up.
12. Push forward on the brake handle to release the brake. (Note you will only need
to have it rotate 10-15 degrees, 1 – 2”, to release the brake).
13. While the brake is released, pull out cable from the winch drum. Draw out enough
cable to run up the back side of the track, thru the peak pulley and back down to
the carriage on the front side (The carriage side). See Figure 6
Figure 6
14. Attach the thimble on the cable to the back of carriage using the 1/2" bolt, nut
and washers. Put 2 1/2" washers between thimble and carriage and 1 1/2"
washer on other side of thimble. Pass the bolt thru the washers, thimble and
then thru the bumper side angle then center hole on carriage. Tighten the 1/2"
bolt so it passes thru the nut, but not so tight as to stop the thimble from
rotating on the bolt. See Figure 7
