Boom - JLG 800S Operation & Safety Manual

Machine Operation

4.12 BOOM

A red tilt warning light is located on the control console which lights when the
chassis is on an excessive slope. Do not swing or raise boom above horizontal when
indicator is lit.
Do not depend on the tilt warning light as a level indicator for the chassis. The tilt
warning light indicates chassis is on an excessive slope. Chassis must be level
before swinging or raising boom above horizontal or driving with the boom
elevated.
To avoid tip over if red tilt warning light lights when the boom is raised above
horizontal, lower platform to ground level. Then reposition machine so that chassis
is level before raising boom.
If the platform does not stop when a control switch or lever is released, remove
foot from footswitch or use emergency stop switch to stop the machine.
To avoid serious injury, do not operate machine if any control lever or toggle switch
controlling platform movement does not return to the 'off' or neutral position
when released.
To avoid a collision and injury if platform does not stop when a control switch or
lever is released, remove foot from footswitch or use emergency stop switch to
stop the machine.
4.12.1 Swinging the Boom
To swing boom, use Swing control switch to select Right or Left direction.
When swinging the boom make sure there is ample room for the boom to clear
surrounding walls, partitions and equipment.
Note: On CE/UKCA market machines, when boom functions are being operated there
is an interlock which prevents the use of Drive and Steer functions.
