Adjusting the Manual Brake Lever
The manual brake release is a means of releasing the multi-plate disc brake allowing the PQ 500 to descend without electrical
power. For this brake release to function properly, adjustment may be necessary to accommodate normal wear of the parts. The
following adjustment should be performed weekly in heavy use or monthly with light use:
1. Locate the proper Allen key (1/16 inch) to fit the two #8-32 set screws.
2. Hang the PQ 500 on a rope with a load of at
least 100 pounds applied.
3. Test for proper tension on the brake lever by
pressing the brake lever. The brake lever will
move about ½ inch when depressed. The first
1/16 to 1/8 inch should have little resistance
followed by higher spring force. The first spring
is just a return spring for the lever, the second
stronger spring is the brake spring. (NOTE if
there is no free play, the brake may not engage,
if there is too much free play, the brake may not
release.) Adjusting this free play is very
important to the function of the machine. This
takes a little practice to get the feel for the
operation.
4. Adjustments:
a. All adjustments should be made so that
the two set screws are generally even.
b. With slight pressure on the brake lever,
loosen one of the set screws about ¼
turn. This should increase the free play
and allow the brake lever to move
downward slightly. Loosen the second set screw a similar amount; this will further increase the free play.
