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 pull the joystick
backward until the desired height is reached.
To lower the platform, push the joystick forward.
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 exten-
sion handle locks are disengaged. Personal injury may
result from accidentally extending or retracting the
deck. Make certain both extension handle locks are
fully engaged when the deck is extended in the work-
ing 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. While facing the front of the platform, firmly grasp
each of the extension handles and squeeze firmly to
unlock the extension deck. Push the extension deck
forward to the desired position, mid or fully extended.
Release the handles to lock the platform in position
(refer to Figure 9.3).
