■ Pothole Protector Skids
The pothole protector skids automatically lower
when the platform is elevated approximately 24
″.
Ground clearance is reduced from 4
″ to about
1 1
4
″ when the skids lock into position (refer to
Figure 4.3).
Figure 4.3—Pothole Protector Skids
The aerial platform can tip over if it becomes
unstable. Death or serious injury can result
from a tip-over accident. Do not drive or
position the aerial platform for elevated use
within four feet of any drop-off, hole, or other
tip-over hazard.
This protection system limits the tilt angle if a
wheel is driven into a drop-off or hole. This
greatly reduces the likelihood of the aerial
platform tipping over.
The pothole protection system is for added
protection and does not justify operating near
drop-offs or holes.
■ Drive/Lift Pothole Protector Interlock
The aerial platform drive and lift functions are
interlocked through a limit switch that senses
whether or not the pothole protection linkage is
locked into position. The drive/lift pothole interlock
operates when the platform is elevated
approximately seven feet.
If an obstruction under the skids, or some other
impairment prevents the skids from locking into
position, the drive and lift functions will not
operate and an alarm will sound.
Lower the platform and remove the obstruction
when the drive/lift pothole protector interlock
alarm sounds.
■ Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are
interlocked through a level sensor system. The
drive/lift level sensor interlock operates when the
platform is elevated approximately seven feet.
If the aerial platform chassis is tilted more than
two degrees side-to-side or four degrees
front-to-rear, the drive and lift functions will not
operate and an alarm will sound.
Lower the platform and drive to a level surface
when the drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added
protection and does not justify operating on
anything other than firm, flat, level surfaces.
■ Guardrails
The guardrail system includes a top rail, mid rail,
and toeboards around the sides of the platform
(refer to Figure 4.4).
Figure 4.4—Guardrails
A safety chain or an optional swinging gate
allows for access to the platform. The swinging
gate closes automatically after entering or exiting
the platform. The chain or gate is part of the
guardrail system and must be securely fastened
after entering the platform.
■ Emergency Lowering Handle
The emergency lowering handle may be used to
manually lower the platform if there is a
malfunction in the hydraulic or electrical system.
The handle (refer to Figure 4.5) is mounted at the
front of the aerial platform.
