Carbon Brush Replacement
● It is essential to check the carbon brush periodically. If its
length is left less than 7.5 mm resulting from wear, it is
absolute necessary to replace carbon brush immediately.
● While replacing, smoothly insert carbon brush into carbon
holder in the first place, then put brush cap into the hole.
● Before tightening the carbon brush holder, make sure to
position O-ring.
● A set of carbon brush consists 2 piece of carbon brush.
Ascertain to replace 2 pieces of carbon brush on opposite
sides of winch body at the same time.
Braking
● Braking device is composed of a mechanic brake and an electronic generated brake. The
brake distance from the time of braking until stopping completely should be within 1.5% of
rope length to the wound in during 1 minute.
● Owing to the rope speed on no load is 1.5 – 1.8 times faster than that on rated load, the
brake distance on no load will be longer, but still within 1.5% of rope length.
● It is highly recommended that any adjustments are carried out by a qualified technician at
an authorized service centre.
● Brake adjustment procedures.
