1.6 TORQUE REQUIREMENTS
NOTE: JLG recommends that once any locknut is removed
from the machine it is discarded and replaced with a
new one. When maintenance becomes necessary or
a fastener has loosened, refer to Figure 1-3., Torque
Chart (SAE Fasteners - Sheet 1 of 3) to Figure 1-8.,
Torque Chart (METRIC Fasteners - Sheet 3 of 3) to
determine proper torque value.
1.7 SENSORS
Platform Stowed/Jacks Retract Limit Switch
Switch that senses when the platform is lowered to 10.5 ft
(3.2 m). Cuts out lowering function, enables drive function
when tilted, and enables outriggers retract when outrig-
gers are deployed.
High Drive Speed Cutout Limit Switch
When the platform reaches and exceeds a height of 12.1 ft
(3.7 m), the fast drive speed will be cut back to the slow
drive speed. Once the platform is completely lowered the
high drive speed is possible. The warning LED will be out
when this limit is exceeded.
Maximum Drive Height/Maximum Height
without Outriggers Limit Switch
The drive function will be disabled once the platform
reaches a height of 65 ft (19.8 m). The platform must be
lowered below the limit to enable the drive function. The
lift function is also disabled once the platform reaches a
height of 65 ft (19.8 m) when the outriggers are not
deployed.
Maximum Height Limit Switch
Once the platform has reached it's maximum height of 80
ft (24.5 m), the lifting function will be cut off by the maxi-
mum height limit switch. When maximum height is
reached, the Lift Cutout Indicator LED on the platform
control console will no longer be illuminated.
Tilt Sensor
The tilt switch cuts out lifting, driving, and steering once
the platform reaches a tilt angle (slope) beyond 3° and the
platform height exceeds 12.1 ft (3.7 m). At this point, the
warning LED on the platform control console will illumi-
nate and lowering is the only function possible.
Outrigger Sensors
Outriggers Selected - Limit switch senses ground contact
for all outriggers to enable platform to be raised.
Outriggers Not Selected - Limit switch senses when all
outriggers are retracted to enable platform to be raised
and machine to be driven.
Oscillating Axle Limit Switch
When the platform is raised above 12.8 ft (3.9 m) and the
axle inclination is >1°, the drive function is cutout by a
limit switch. When the platform is below 12.8 ft, the inclina-
tion of the axle is ignored and driving is possible.
