Figure 4.6 – Upper Controls
The entry gate allows for access to the platform. The gate
must be closed except when personnel are entering or
leaving the platform.
Tilt Alarm
An alarm will sound if the aerial platform chassis is out of
level more than two degrees side-to-side or two degrees
front-to-rear when the platform is raised.
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. Do not position the aerial platform for elevated
use near any drop-off, hole, slope, soft or uneven
ground, or other tip-over hazard.
Completely lower the platform and move to a level surface
when the tilt alarm sounds.
The tilt alarm is for added protection and does not justify
operating on anything other than firm, flat, level surfaces.
Lift Level Sensor Interlock
The aerial platform lift functions are interlocked through
a level sensor system. The lift level sensor interlock
operates when the platform is elevated approximately
6′ (1.8 m).
If the chassis is tilted more than 2 degrees side-to-side
or more than 2 degrees front-to-rear, the lift functions will
not operate and an alarm will sound.
Lower the platform and move to a level surface when the
lift level sensor alarm sounds.
The lift level sensor system is for added protection and
does not justify operating on anything other than firm,
flat, level surfaces.
Lowering Alarm
When a platform control button is pressed to lower the
platform, the alarm emits a loud beeping sound to warn
personnel in the work area to stand clear.
Danger
Pinch points exist on the scissors structure. Death
or serious injury will result if the scissors structure
lowers onto personnel within the scissors arms or
under the raised platform. Stand clear while raising
and lowering the platform.
Be careful when lowering the platform. Keep hands and
fingers away from the scissors structures components.
Emergency Lowering System
The emergency lowering system may be used to lower
the platform if there is a malfunction in the hydraulic or
electrical system.
On PUSH PRO 6, 8, 10 machines the lowering lever
is at the rear of the aerial platform (refer to Figure 4.4).

Safety Props
The safety props (refer to Figure 4.5) are used to support
the scissors structure when access to the scissors arm
components or the chassis is required. Always use the
safety props when the platform is raised during inspection
and maintenance.
