Function Check
A functional check of all systems should be performed, once the
walk-around inspection is complete, in an area free of overhead
and ground level obstructions. First, using the ground controls,
check all functions controlled by the ground controls. Next, using
the platform controls, check all functions controlled by the plat-
form controls.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL LEVERS OR
TOGGLE SWITCHES CONTROLLING PLATFORM MOVEMENTS DO NOT RETURN TO THE
OFF 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 EMER-
GENCY STOP TO STOP MACHINE.
1. Check boom limit switches. Raise and lower the Lower
Boom. Check for smooth operation.
NOTE: Perform checks from ground controls first, then from platform
controls.
2. Raise, extend, retract, and lower the Upper Boom. Check for
smooth operation.
3. If tower boom does not rest on stop with machine in the
stowed position, this indicates upright is out of plumb.
4. Telescope boom In and Out several cycles at various degrees
of elevation lengths. Check for smooth telescope operation.
5. Swing turntable to Left and Right a minimum of 45 degrees.
Check for smooth motion.
6. Check the chassis tilt indicator located on the platform con-
trol console by driving, with the machine in stowed position,
up a suitable ramp of at least 6° slope. Check the tilt alarm,
with the machine on the ramp, raise the upper boom until it
is parallel with the chassis. DO NOT RAISE ABOVE THE PARAL-
LEL POSITION. If the light does not illuminate, return the
machine to a level surface, shut down the machine, and con-
tact a qualified technician before resuming operation.
For units equipped with optional tilt cutout, verify that the
drive function is cutout when the boom is elevated and tilt
alarm is activated.
DO NOT DRIVE ON GRADES WHICH EXCEED THE RATED GRADEABILITY OF THE
MACHINE AS INDICATED ON THE SERIAL NUMBER PLATE. DO NOT DRIVE ON SIDES-
LOPES WHICH EXCEED 5 DEGREES.
