Travel is accomplished by pressing on travel pedals (2) and (3). Steps (1) and (4) can be used as footrests.

If you move a travel pedal farther in the forward direction, the forward travel speed will increase. If you move a travel pedal farther in a reverse direction, the reverse travel speed will increase.

Move both of the travel pedals equally in the same direction in order to travel straight.

When the travel pedals are moved in the reverse direction, the machine will always travel toward the sprockets. When the travel pedals are moved in the forward direction, the machine will always travel toward the track idlers. Release the travel pedals in order to stop the machine. When you release the travel pedals from any position, the travel pedals will return to the CENTER position.

Engine Start Switch




Illustration 37g00932572

The engine start switch is an input to the left joystick. The start switch is a three position switch. The start position is a momentary position. Once the engine has started the switch moves into the run position. The switch will remain in the run position until the switch is turned to the off position.

Throttle Control




Illustration 38g00932602

The throttle control is an input to the left joystick. The throttle control is a potentiometer with a total resistance of approximately 5000 ohms. Adjusting the position of the throttle control will adjust the engine RPM accordingly.

Travel Switch (Two Speed)




Illustration 39g00932641

The travel switch (two speed) is an input to the left joystick. The switch is a normally open, single pole, and single throw switch. In the normally open position, the machine remains in the normal operating speed mode. When the switch is closed, the machine will operate in the low speed mode.

Travel or Hood Movement Audible Indicator (Cancel Switch)




Illustration 40g00932667

The travel or hood movement audible indicator (cancel switch) is an input to the right joystick. The switch is a momentary normally open, single pole, and single throw switch. When the audible indicator is active, the cancel switch can be activated in order to turn off the indicator.

Saw (On/Off Switch)




Illustration 41g00932704

The saw on or off switch is an input to the right joystick. The switch is a single pole double throw switch. When this switch is turned off the saw will be turned off. When the saw on or off switch is turned on, the saw will be activated.

Automatic Switch (Accumulator Arm)




Illustration 42g00932735

The automatic switch (accumulator arm) is an input to the right joystick. The switch is a normally open, single pole, and single throw switch. When this switch is closed, the machine will automatically accumulate.

Reversing Fan Switch




Illustration 43g00932765

The reversing fan switch is an input to the right joystick. When the reversing fan switch is activated, the direction of the air flow through the fan will be reversed.
