machine. When the platform rises to the level of the
fork and leaves the pressure lever of the pothole
guard, the pothole guard activates. If the pothole
guard does not activate, the alarm will sound and the

guard activates automatically when the platform lifts
to the level of the fork and leaves the pressure lever
of the pothole guard.
