Test the Drive Brakes
BALLYMORE/ DINGLI requires that this
procedure be performed every 250 hours or
quarterly, whichever comes first.
Proper brake action is essential to safe
machine operation. The drive brake function
should operate smoothly, free of hesitation,
jerking and unusual noise.
Hydraulically-released individual wheel brakes
can appear to operate normally when not fully
operational.
Perform this procedure with the machine on a
firm level surface that is free of obstructions,
with the platform extension deck fully retracted
and the platform in the stowed position.
1 Mark a test line on the ground for
reference.
2 Turn the key switch to platform control and
turn the red Emergency Stop button
clockwise to the on position at both the
ground and platform controls.
3 Lower the platform to the stowed position.
