Safety Interlock System
• PTO must be disengaged, brake engaged, and
motion control levers out (neutral lock) to start
engine. (It is not necessary for the operator to be
in the seat to start the engine.)
• 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 overow 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.
