Foot Switch Adjustment; Platform Control Enable System - JLG 600SC Service And Maintenance Manual

SECTION 4 - BOOM & PLATFORM
4. The first attempt to remove debris from inside the boom
must be to utilize pressurized air to blow the debris
toward the nearest exiting point from the boom. Make
sure that all debris is removed before operating the
machine.
5. If pressurized air cannot dislodge debris, then water
with mild solvents applied with a pressure washer can
be used. Wash debris toward the nearest exiting point
from the boom. Make sure all debris is removed, no
"puddling" of water has occurred, and boom internal
components are dry before operating machine. Make
sure you comply with all federal and local laws for dis-
posing of wash water and debris.
6. If pressurized air or washing boom does not dislodge
and remove debris, disassemble boom following
instructions outlined in the JLG Service & Maintenance
Manual to remove debris.

4.18 PLATFORM CONTROL ENABLE SYSTEM

The platform controls use a time dependant enable circuit to
limit the time availability of "live" or enabled controls. When
the footswitch is depressed, the controls are enabled and the
operator has 7 seconds to operate any control. The controls
will remain enabled as long as the operator continues to use
any function and will remain enabled 7 seconds after the last
function has been used. While the controls are "live", the
enabled light will be illuminated in the platform display panel.
When the time limit has been reached, the enabled light will
turn off and the controls will be disabled. To continue use of
the machine the controls must be re-enabled to start the timer
system over again. This is done by releasing all functions, then
releasing and re-depressing the footswitch.
