•Operator must be in seat when PTO is engaged, brake is disengaged, or motion control levers are moved in or engine will stop.

•Engine will stop if either the left, the right, or both levers are moved from neutral lock position while brake is engaged.

Engine Overheat Protection System

PTO will disengage, an alarm will sound, and the coolant temperature gauge will be in the red area when the engine temperature reaches an overheat condition. The PTO will not re-engage until the engine has cooled and the PTO switch is manually shut-off and re-engaged.

Note: If the engine coolant level is below the indicator line on the overflow bottle when the engine is cold, the coolant temperature gauge may not register correctly during operation and/or the warning buzzer may not sound if the engine overheats. Refer to Check Engine Coolant Level in Maintenance.

Cooling System

•Fan: Electric with continuous operation with engine running.

•Coolant Liquid: 50/50 mix of DexCool© extended life antifreeze and water.

•Coolant Capacity: 4 quarts

Operator Controls

•Steering and Motion Control:

Note: Motion control levers are adjustable to two heights.

–Separate levers, on each side of the console, control speed and direction of travel of the respective drive wheels.

–Steering is controlled by varying the position of the levers relative to each other.
