SECTION 4 - MACHINE OPERATION
3121110 – JLG Lift – 4-3
Platform Extension
The machine is equipped with a mechanically extendable
deck, which adds 3 feet (0.9 meters) to the front of the
platform, giving the operator better access to worksites.
To extend the deck, pull out handle from latch and swing
up, then use the handles and handrail to push the extend-
able deck out. To retract the deck, pull out the handles
from latch and swing up, use the handles and handrail to
pull and retract the deck. Be sure the lock pin is locked in
place after the deck is retracted. Maximum capacity of the
deck extension is 250 lb (120 kg).
DO NOT ‘LIFT DOWN’ WITHOUT COMPLETELY RETRACTING THE
PLATFORM EXTENSION.
4.5 STEERING
To steer the machine, the thumb operated steer control
switch on the controller handle is positioned to the right
for traveling right, or to the left for traveling left. When
released, the switch will return to the center-off position
and the wheels will remain in the previously selected posi-
tion. To return the wheels to the straightened position, the
switch must be activated in the opposite direction until the
wheels are centered.
