OPERATING CONTROLS AND FEATURES GRT9165 OPERATOR MANUAL
3-8 Published 7-23-2020, Control # 668-02
NOTE: Transmission must be shifted to four-wheel drive
(low range) before outriggers can be operated.
Hazard Lights Switch
The Hazard Lights Switch (6, Figure 3-2) is located on the
front of the steering column.
The switch is a two-position rocker switch (ON/OFF).
Push top of switch to cause the turn signal lights on the front
and back of the crane, and the turn signal indicator lights on
the steering column, to flash at the same time. Push bottom
of switch to cause these lights and indicators to go off.
Transmission Shift Lever
The Transmission Shift Lever (7, Figure 3-2) is located on
the right side of the steering column. The lever is used to
shift the transmission between forward, neutral, and reverse.
Push Transmission Shift Lever up to shift transmission to
forward gear. Push Transmission Shift Lever down to shift
transmission to reverse gear.
The lever sits in a detent when in the center neutral position.
Thus, operator must first lift up on lever before pushing it up
or down.
A shift interlock system prevents the transmission from being
shifted between forward, neutral, and reverse without first
pushing and holding the Service Brake Pedal
(2, Figure 3-26). Thus, crane must be stopped, and Service
Brake Pedal pushed and held before.shifting between
forward and reverse gears.
NOTE: Transmission Shift Lever must be in Neutral (center
position) before the following operations can be
performed:
• Shifting transmission between two-wheel drive
(high range) and four-wheel drive (low range)
• Operating the outriggers
• Reversing the driving controls (refer to
Steering Reversal Switch, page 3-14)
To shift transmission to first, second, or third gear, rotate
knob at end of the lever to I, II, or III.
The transmission has six forward gears and six reverse
gears. To use the three low gears, set Drive Axle Selector
Switch (5, Figure 3-2) to four-wheel drive. To use the three
high gears, set Drive Axle Selector Switch to two-wheel
drive.
The Direction/Gear Indicator in the Crane Information Area
(3, Figure 4-74) of the Operating Display Module (ODM)
shows the chosen direction of travel and chosen gear to
which the transmission is shifted.
The GRT9165 crane can be driven in the Standard Driving
Configuration with the boom centered over the front (single
axle) or in the Alternate Driving Configuration with the boom
centered over the rear (tandem axles).
The transmission shift lever control can be reversed to allow
it to operate intuitively when driving in either of these two
directions,
Before driving the crane in the Alternate Driving Config-
uration, with the boom centered over the rear (tandem
axles), push the Steering Reversal Switch (16, Figure 3-9)
one time to reverse all driving controls, including the
transmission shift lever control. The Steering Reversed
Indicator in the Alerts Area (1, Figure 4-74) and Crane Status
Area (4, Figure 4-74) of the Operator Display Module (ODM)
comes on to indicate that all driving controls, including the
transmission shift lever control, are reversed
.
When the boom is swung back and centered over the front
(single axle), push the Steering Reversal Switch again to set
the transmission shift lever control back to its normal
operation. The Steering Reversed Indicator on the ODM
goes off to indicate that the transmission shift control lever is
not reversed.
Before driving the crane, read, understand, and follow the
directions found in these sections of this Operator Manual:
• Steering Wheel, page 3-5
• Standard Driving Configuration, page 3-5
• Alternate Driving Configuration, page 3-6
• Turn Signal Lever and Horn Controls, page 3-6
• Transmission Shift Lever, page 3-8
• Steering Reversal Switch, page 3-14
• Rear Steer Switch, page 3-28
Ignition Switch
The Ignition Switch (8, Figure 3-2) is located on the right side
of the steering column, below the Transmission Shift Lever
(7, Figure 3-2).
The Ignition Switch is key-operated and has three positions:
0 (OFF), I (RUN), and II (START).
In the OFF(0) position, most electrical power is off. Electrical
items that continue to operate include the horn, headlights,
turn signal/hazard/stop lights, dome light, and work lights.
CAUTION
Transmission Damage!
To prevent transmission damage, shift between
two-wheel and four-wheel drive only with crane is
stopped, transmission in Neutral (center) position, and
service brake pedal pushed.
