1. Travel Control - controls the machine travel speed and direction (forward or reverse) by adjusting the swashplate tilt angle of the wheel drive pump. This control should be at "N" whenever the machine is parked and must be at "N" whenever the engine is started.

------ WARNING! ------

IF THERE IS PRESSURE IN THE WHEEL DRIVE SYSTEM, THE MACHINE MAY LUNGE FORWARD OR BACKWARD WHEN THE EMERGENCY BRAKE IS MOVED TO "OFF" AND THEREBY CAUSE AN INJURY. BE SURE THE WHEEL PRESSURE GAUGE IS AT "O" AND THE TRAVEL CONTROL IS AT "N" BEFORE RELEASING THE EMERGENCY BRAKE.

------WARNING!--------

2. Front Steering Control - controls the hydraulic cylinder that turns the front wheels to the "Left" or "Right".

3. Rear Steering Control - controls the hydraulic cylinder that turns the rear wheel to the "Left" or "Right".


NOTICE

IN ORDER TO KEEP CUTTER WEAR TO A MINIMUM WHENEVER CUTTING, USE BOTH THE FRONT AND REAR STEERING CONTROLS WHEN TURNING. THE FRONT AND REAR WHEELS SHOULD BE TURNED THE SAME AMOUNT.


4. Emergency Brake Control - engages or disengages the brake on the front wheel if the engine is running. If the engine is not running or the accessory hydraulic system pressure falls below 180 psi (1241 kPa), the brake will automatically engage. Setting the control to "Off" directs accessory hydraulic pressure to the brake to release it. Setting the control to "On" relieves the pressure and engages the brake.
5. Accessory Pressure Gauge - shows the pressure in the accessory hydraulic system. Pressure should be 2000 psi (13 790 kPa).
6. Wheel Pressure Gauge - shows the pressure in the wheel drive hydraulic system. Maximum pressure should be 4400 to 4500 psi (30 338 to 31 028 kPa).
