OPERATING PROCEDURES

GRT8120 OPERATOR MANUAL

4-18

Published 3-22-2021, Control # 702-02

Four-Wheel Drive Operation

If more traction is required due to slipping or spinning
wheels, engage the rear axle drive as follows: 

1.

Stop crane by pressing Service Brake Foot Pedal.

2.

Position Transmission Shift Lever to neutral (N) position.

3.

Position Drive Axle Selector Switch to four-wheel drive.

NOTE:

If Drive Axle Selector Switch is positioned to
four-wheel drive, Service Brake Foot Pedal is not
pressed, and Transmission Shift Lever is not in
neutral (N) position Four-Wheel Drive Indicator will
flash and four-wheel drive function will not engage.

4.

Select gear speed and direction of travel with Transmission 
Shift Lever and Knob.

5.

Drive crane following 

Traveling — Forward

, page 4-16.

6.

Return Drive Axle Selector Switch to two-wheel drive
position as soon as two-wheel traction will suffice and
crane motion has stopped. Service Brake Foot Pedal
must be pressed and Transmission Shift Lever must be
in Neutral (N) position to shift from four-wheel drive to
two-wheel drive.

Differential Lock Operation

NOTE:

Differential lock will not operate unless Drive
Selector Switch is in four-wheel drive position.

General

The purpose of the differential lock is to provide maximum
traction and control on poor road or highway surfaces. When
differential locks are actuated, the clutch collar completely
locks the differential case, gearing, and axle shafts together,
maximizing traction to both wheels of each axle. The lock
position will also protect against spinout. 

When normal driving conditions exist (during periods of good
traction), differential locks should not be actuated. Axles
should be allowed to operate with differential action between
both wheels.

Obey the following precautions when engaging/disengaging
the differential lock function.

1.

Lock/unlock differentials only when vehicle is standing
still or moving at a constant low speed with wheels not
slipping. 

2.

When traveling with differentials locked, do not deviate
from a straight path more than absolutely necessary. 

3.

Locked differentials cause crane’s turning radius to
increase, creating an understeer condition. Use caution,
good judgment, and drive at low speeds when operating
vehicle with locked differentials.

4.

Lock differentials only when maximum traction is
needed on poor road or highway surfaces. 

5.

Always unlock differentials when the need for maximum
traction has passed or when traveling on good road or
highway surfaces.

Operation

The differential lock function should preferably be engaged
when crane is stationary but may be engaged when moving,
if the following conditions are met:

•

Crane is moving very slowly (creep speed).

•

Wheels are not slipping at time of engagement.

CAUTION

Machine Damage Hazard!

Do not tow or pull in 1st gear with Drive Axle Selector

Switch in two-wheel drive position. Severe damage to

drivetrain will result. Always engage four-wheel drive.

CAUTION

Possible Machine Damage!

Before shifting from two-wheel drive to four-wheel drive
(or from four back to two), crane travel must be stopped.

CAUTION

Unexpected Operation!

When using differential lock, steering characteristics may
be affected.
Try to use four-wheel drive to gain adequate traction
before using differential lock.
Do not operate differential lock when traveling downhill; at
speeds above 16.1 km/h (10 mph); on hard, dry surfaces;
and/or during axle spin-out.

CAUTION

Possible Machine Damage!

When driving on hard, dry surfaces with differentials
locked, do not turn the wheels. Damage to drive line
components can result.
Do not lock differentials when wheels are slipping.
Damage to differentials can result.

 CAUTION

Possible Loss of Vehicle Stability!

Do not lock differentials when vehicle is traveling down
steep grades and traction is minimal.
