4.4 RAISING AND LOWERING (LIFTING)
DO NOT RAISE PLATFORM EXCEPT ON A FIRM, LEVEL SURFACE
FREE OF OBSTRUCTIONS AND HOLES.
NOTE: This machine is equipped with a Enable Switch on
the side of the platform control console. This switch
must be depressed before activating DRIVE, LIFT, or
STEER functions from the platform control console.
Raising
NOTE: On machines equipped with leveling jacks, leveling
jacks must be in contacted with the ground for lift
system to raise above 6.7 m. (22 ft).
1. Position MAIN POWER switch to desired position
and position POWER ON (platform) or EMERGENCY
STOP (ground) switch, as applicable, to ON. If
machine has been shut down, start engine and
allow warm-up period before beginning any lifting.
2. Pull LIFT toggle switch, then move it to UP and hold
until desired elevation is achieved.
Lowering
ENSURE SIZZOR ARM AREA IS FREE OF PERSONNEL PRIOR TO
LOWERING PLATFORM.
DO NOT ‘LIFT DOWN’ WITHOUT COMPLETELY RETRACTING THE
OPTIONAL TRAVERSING DECK.
Pull LIFT toggle switch, then move it to DOWN and hold
until desired elevation is achieved or until platform is fully
lowered.
4.5 TRAVERSING PLATFORM (OPTIONAL)
The machine may be equipped with hydraulically oper-
ated traversing platforms that moves 1.2 m (4 ft) at each
end of the machine to give the operator “up and over”
access to worksites. The traversing platform is operated
by either the TRAVERSE toggle switches at platform con-
trol console or the TRAVERSE toggle switch at the ground
control switches.
TO AVOID INJURY TO GROUND PERSONNEL, RETRACT TRA-
VERSING PLATFORM COMPLETELY BEFORE LOWERING PLAT-
FORM.
4.6 STEERING

switch on the controller handle is positioned to the right
for traveling right, or to the left for traveling left.

tion steer control switch to right for traveling right, or to left
for traveling left.
When released, the switch will return to the center-off posi-
tion and the wheels will remain in the previously selected
position. To return the wheels to the straightened position,
the switch must be activated in the opposite direction until
the wheels are centered.
