XRead this manual carefully
You should carefully read and understand this manual before operating it.
Careless hoist operation may result in personal injury hazards or property
damage.
XInformation requesting or parts ordering
Please specify the following information:
．Hoist PN ．Part description
．Serial number ．Replacement part number
．Quantity for each part
Installation
Before using the hoist, make sure all electrical components have no corrosion
or damaged; the environment should be clear and dry.
Attach fix plates to the foot of motor/gearbox support racks securely.

XWire Rope Replacement
．Feed the end of the wire rope into No. 1 anchor hole in the
drum and wind about 1/4 wrap of rope on the drum. Insert
the wire rope into No. 2 hole and tighten the set screw
securely.
．Make sure the first layer of wire rope is tight and maintain
a freeboard at least 1.5 x rope diameter.
．Wire rope shall be wound in an under-wound orientation
only.
．To compensate for uneven spooling and the decrease in
line pull capacity as the drum fills up, use as short a wire
rope as practical.
XWiring Diagram
Attach the black lead firmly to the negative (–)battery terminal and red lead to
the positive (+) battery terminal. The voltage drop for the hoist motor must not
exceed 10% of the nominal voltage of 12/24V DC.
．Recommended battery: 650 CCA minimum for hoisting
