1. 'Off' Position
2. 'On' Position
3. Heat Position
4. Starter Position
Turning the key right to the "ON" position
activates the warning lights and instruments.
The pre-heat system is activated when the key
is turned further to the right to the "HEAT"
position, and the engine starts when the key is
turned to the extreme right. The key spring
returns to the "ON" position when released.
PRE-HEATING THE SYSTEM
Your CM mower has a diesel engine. Before
starting a cold engine, the precombustion
chambers must be heated.
To pre-heat the engine, turn the key switch to
the "HEAT" position and hold the key in this
position for approximately 5 seconds. The glow
plugs heat the precombustion chambers during
this time, and the engine will start.
The starting circuit can only be activated when:
1. Operator is seated.
2. HST foot pedals are released.
3. PTO lever is in the "OFF" position.
4. Brake pedal is depressed or parking brake
lever is locked.
For safe operation, always check to make
certain the lift control lever is in neutral before
attempting to start engine. Refer to page 2-7 for
complete starting instructions.
IMPORTANT: The key start switch must remain
in the "ON' position while operating the engine.
The warning lights and battery charging system
will not function with the switch in the "OFF"
position.
