Test and Adjust
CAUTION:
When adjusting the timing of the hoist, always make small
incremental adjustments. Do not adjust the timing by more than a total of 1/2
turn in either direction. If the noise persists after adjustments, contact
ETC Technical Services.

As noted earlier, the direction in which
you adjust the timing and the degree of
rotation to which you adjust the timing
can have varying effects on the hoist
noise. Once you have performed the first
adjustment, you should notice a
difference and can determine what steps
to take:
•
If you rotated 1/8 turn
counterclockwise and the noise is
worse, try rotating 1/4 turn
clockwise
•
If you rotated 1/8 turn
counterclockwise and the noise is
better but still present, try rotating
another 1/8 turn counterclockwise
The image to the right shows a
transparent screw end with the screw
end anchor screw holes identified. There
are three additional screw holes on the
side of the anchor not shown.
Note:
When adjusting the timing using a clockwise rotation, the screw end anchor
(and hoist internals) will shift out of the end of the hoist and away from the motor. To
realign the M5 screw holes on the screw end anchor, use your hands to push everything
back in place.
Adjust SafeStop Device Position for Fleet Angle
If adjusting the timing of the hoist has not resolved the thumping noises, you can attempt to
identify any specific SafeStop devices from which the noise is originating and adjust them
individually. You can adjust the fleet angle by repositioning the SafeStop device over the
extrusion from which the lift lines exit the drum.
It is recommended that you run your hoist through the full range of travel to determine if and
when these noises occur, while at the same time, identifying which SafeStop devices are
affected. If you identify an issue, you can attempt to adjust the SafeStop device and in turn, the
fleet angle of the lift lines running through that device.
