Platform
Use care when entering and exiting the platform to avoid
slipping and/or falling. Securely close the entry doors
when the platform is occupied.
Raising and Lowering
The raise speed is proportional to the joystick position.
The farther the joystick is moved, the faster the platform
raises. There is only one lowering speed.
1. Place the drive/lift selector switch (refer to Figure 9.2)
in the lift position.
2. Squeeze and hold the interlock switch against the
joystick.
To raise the platform, slowly push the joystick
forward until the desired height is reached.
To lower the platform, pull the joystick backward.
Extending
The platform can be extended and securely locked into
position.
Use the following procedure to extend the platform:
1. Enter the platform and secure the doors.
Caution
The extension deck is free to move when the snapper
pins are removed, the latch handles are raised and the
locks are disengaged. Personal injury may result from
accidentally extending or retracting the deck. Make
certain both latch handles are fully lowered, the snap-
per pins are in place and the locks are fully engaged
when the deck is extended in the working position
and when it is stowed. Do not attempt to extend or
retract the platform unless the aerial platform is on a
level surface.
2. Release the latch from each of the snapper pins.
While facing the front of the platform, firmly grasp
each of the latch handles and raise them to unlock
the extension deck. Push the extension deck forward
to the desired position, mid or fully extended. Fully
lower the handles to lock the platform in position and
replace the snapper pins (refer to Figure 9.3).
