BRACKET AS-MOUNTING 4E9716 - Caterpillar

The All Wheel Steer (AWS) has three steering modes: All Wheel Steer, Two-Wheel Steer and an Independent Rear Maneuvering mode. When you operate the machine for the first time, become familiar with the three modes by trying each one. This should be done in an area that is clear of personnel and of obstacles.

The All Wheel Steer mode consists of the following components:
an All Wheel Steer switch (1) that allows the operator to choose from the three modes
a rear axle position gauge (2)
an alert indicator (3)
an independent rear maneuvering switch (4) Three modes provide maximum machine performance under various conditions at the job site.

Two-Wheel Steer - The Two-Wheel Steer mode (5) offers the capability to operate the machine on the road. The Two-Wheel Steer mode is used when additional maneuvering capability is not needed. Only the front axle is used to steer the machine. Use this mode when you are roading the machine. When you are operating the machine in this mode the indicator light (3) will not be on.
All Wheel Steer - The All Wheel Steer mode (6) allows the operator to choose independent rear maneuvering for positioning the rear axle and for controlling the rear axle. The switch that is located on the loader control lever is used for positioning and for controlling the rear axle. When you are operating the machine in the All Wheel Steer mode, the indicator light (3) will be on.

Circle Steer Mode - The Circle Steer Mode (7) provides reduced turning radii and tighter operation in confined spaces. The front and rear axles are used to steer the machine. When you are operating the machine in the Circle Steer mode, the indicator light (3) will come on.
Before changing from one steering mode to another, always center both the front and rear wheels.
Before you return to the Two-Wheel Steer mode or to the Circle Steer mode, the front wheels and rear wheels must be centered. Observe the rear axle position gauge (2) on the front console. Use the independent rear maneuvering switch (4) to center the rear wheels until the zero position is obtained. Then, move the All Wheel Steer switch to the desired mode.
