Platform Station - JLG 340AJ Operation And Safety Manual

Platform Station

(See Figure 3-4., Platform Control Console)
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL LEVERS OR
TOGGLE SWITCHES CONTROLLING PLATFORM MOVEMENT DO NOT RETURN TO THE
OFF OR NEUTRAL POSITION WHEN RELEASED.
1. Drive Speed/Torque Select
The machine has a three position switch - The forward posi-
tion gives maximum drive speed by allowing the drive pump
to go to maximum displacement and the engine to go to
maximum RPM when the drive controller is moved. The back
position gives maximum torque for rough terrain and climb-
ing grades by reducing the drive pump displacement and
keeping the engine at high RPM, when the drive controller is
moved. The center position allows the machine to be driven
as quietly as possible by leaving the engine at mid engine,
and the drive pump at a reduced displacement.
ONLY USE THE PLATFORM LEVELING OVERRIDE FUNCTION FOR SLIGHT LEVELING OF
THE PLATFORM. INCORRECT USE COULD CAUSE THE LOAD/OCCUPANTS TO SHIFT OR
FALL. FAILURE TO DO SO COULD RESULT IN DEATH OR SERIOUS INJURY.

2. Platform Leveling Override
A three position switch allows the operator to adjust the
automatic self leveling system. This switch is used to adjust
platform level in situations such as ascending/descending a
grade.
3. Horn
A push-type HORN switch supplies electrical power to an
audible warning device when pressed.
4. Power/Emergency Stop Switch
A two-position red mushroom shaped switch furnishes
power to PLATFORM Controls when pulled out (on). When
pushed in (off ), power is shut off to the platform functions.
