Starting Procedure
Normal Starting
Safety Interlocks
The safety interlocks are as follows:
• Operator must be in the seat.
• Seat belt must be latched.
• Cutter Wheel is Off.
The engine will not start unless the safety interlocks are
engaged. Once the engine is running, if any of these interlocks
are disengaged, the engine will remain running; however, all
machine movement will be interrupted.
Set the throttle control to SLOW or medium-slow position.
Insert the key and turn the key switch to ON; check indicator
lamps for malfunctioning bulbs.
Turn the key switch to START; release the key switch once
the engine has started.
Allow the engine to warm up before increasing throttle.
Pre-Operation Warm-Up
Allow a cold engine to warm up at a low idle for at least five
minutes. To help the hydraulic systems to warm up faster,
cycle the controls. Raise the mower to its upper limit and
continue pulling the mower control joystick back. This cycles
oil through the control valves at system relief pressure and will
shorten the time required to warm up the oil. Cycle the mower
in this fashion for periods of ten seconds on, ten seconds off.
Look at the gauges and indicator lamps frequently during
warm-up and operation.
Under cold conditions, the hydraulic filter restriction indicator
lamp may come on. Under extremely cold conditions, the
hydraulic filter may shut down the track transmissions and all
hydraulic functions. As the hydraulic oil warms up, the track
functions should return and the hydraulic filter restriction
indicator lamp should go out. If, after the oil has warmed up,
the lamp does not go out, the machine should be shut down
and the cause determined. The most likely cause would be
that the filter element needs serviced.
• Cycle all controls to allow warm oil to circulate into all
lines and cylinders.
• Allow the machine to warm up for 15 minutes in
temperatures above 0°C (32°F).
• Allow the machine to warm up for 30 minutes in
temperatures below 0°C (32°F).
• More time may be required below -18°C (0°F).
Operation
NOTICE
Do not operate the starter for more than 10
seconds at a time. If the engine does not start,
allow a 60-second cool-down period between
starting attempts. Failure to follow these guidelines
may burn out the starter motor.
If the key switch is released before the engine
starts, wait until the starter and the engine stops
turning before trying again. This will prevent pos si-
ble dam age to the starter and/or flywheel.
