SECTION 3 - MACHINE CONTROLS AND INDICATORS
3121261 – JLG Lift – 3-13
Manual Mode:
When the boom control is positioned to Man-
ual, lift and telescope movements are con-
trolled separately by the operator and the
automatic platform leveling feature is active
only during lift functions.
NOTE: When positioned to Manual, boom functions will be stopped
when the envelope limits are reached. When this occurs, operate
a different function or select the automatic position.
NOTE: Depending upon the angle of the chassis and the angle of the
boom, swing left or swing right may be disallowed while in the
Manual mode. The BCS light will illuminate and further attempts
to swing in the disallowed direction will cause the BCS to flash.
When this occurs the only choices are to swing in the opposite
direction or switch to automatic mode.
8. Power/Emergency Stop
A two-position red mushroom shaped switch
supplies power to Platform Controls when
pulled out (on). When pushed in (off ), power is
shut off to the platform controls.
9. Start/Auxiliary Power
When pushed forward, the switch energizes the
starter motor to start the engine.
When pushed back, it energizes the electrically
operated hydraulic pump, when actuated. (Switch
must be held on for duration of auxiliary pump
use.)The auxiliary pump functions to provide suffi-
cient oil flow to operate the basic machine functions should
the main pump or engine fail. The auxiliary pump will oper-
ate platform rotate, jib lift, jib level, jib telescope, jib stow,
platform level, main boom lift, main telescope and swing.
