TROUBLESHOOTING (continued)
PROBLEM CAUSE SOLUTION
Load is easing down slowly
The brake on the winch need to
be set when the load is at the de-
sired height
When load is in position, crank
winch handles forward a half turn
towards the lift to set the brake.
You have serviced the winch
and now the brake does not
work at all
The brake ratchet or ratchet dog
are not installed correctly
Check the winch drawing in this
manual and correct the
installation problem
The brake is over-engaged See illustration and instructions
below
The brake will not disengage See illustration and instructions
below
The idler gear is displaced Make sure that the idler rotates
freely and the teeth on the idler
gear are not worn
Safety brake will not release
Unit may not be in the vertical
position
Place unit in vertical position and
wind mast sections up to full
extension.
Unit is vertical and brakes will
not release
Mast section or carriage is too
close to mast stop and does not
have enough clearance between
mast stops for brakes to release
Use release hook to manually
disengage safety brakes
Unit is being serviced or unit
is not in vertical position
Brakes will engage if unit is
horizontal or tilted off center
Use release hook to disengage
brakes
The winch is hard to crank
down
For proper adjustments on the EVENTER Lift winch, the pinion and drive shaft must be in the
position shown when the lock nut is tightened against the O.D. brake disc to 15 ft. lbs.
*Correct alignment is only visible when load is applied to lift.
