De-reeve the wire rope:
Re-insert the rope about 12" (30 cm)
into the hoist.
Holding the wire rope firmly, pull it out
quickly
. If the overspeed brake is working
correctly, it will grip and hold the wire rope in
less than 4" (10 cm).
Run the hoist
UP and release the
overspeed brake by turning the overspeed
brake RESET lever clockwise in the
UNLOCK direction. The overspeed brake
ACTIVATION lever should return to its
vertical, locked position.
Repeat this test at least 3 times.
If the overspeed brake does not operate
correctly every time, DO NOT USE THE
HOIST. Return the hoist to your supplier.
