3. Turn the ignition key to the Run position. The
glow indicator will light.
4. When the glow indicator dims, turn the
ignition key to the Start position. Release the
key immediately when the engine starts and
allow it to return to the Run position. Allow
engine to warm up at mid speed (without load),
then move the throttle control to the desired
position.
Important: Do not run the starter
motor more than 15 seconds at a time or
premature starter failure may result. If the
engine fails to start after 15 seconds, turn
the key to the Off position, recheck the
controls and procedures, wait 15 additional
seconds, and repeat the starting procedure.
When the temperature is less than 20°F
(-75C), preheat glow plugs twice prior to initial
cranking attempt. The starter motor can be
run for 30 seconds on then 60 seconds off for
2 attempts.
5. When the engine is started for the first time, or
after an overhaul of the engine, transmission,
or axle, operate the machine in forward and
reverse for one or two minutes. Also operate
the lift lever and PTO lever to ensure proper
operation of all parts. Turn the steering wheel
to the left and right to check steering response.
Then shut the engine off and check for oil
leaks, loose parts, and any other noticeable
difficulties.
Shut the engine off and wait for all
moving parts to stop before checking
for oil leaks, loose parts, and other
malfunctions.
6. To stop the engine, move the throttle control
backward to the Slow position, move the PTO
lever to the Off position, set the parking brake,
and rotate the ignition key to Off. Remove
the key from the switch to prevent accidental
starting.
Important: Allow engine to idle for 5
minutes before shutting it off after a full
load operation. Failure to do so may lead to
turbo-charger trouble.
Checking the Interlock
Switches
If safety interlock switches are disconnected
or damaged the machine could operate
unexpectedly causing personal injury.
• Do not tamper with the interlock
switches.
• Check the operation of the interlock
switches daily and replace any damaged
switches before operating the machine.
The machine has interlock switches in the electrical
system. These switches are designed to stop the
engine when operator gets off of the seat when the
traction pedal is depressed. However, the operator
may get off of the seat while the engine is running
and the traction pedal is in neutral. Although the
engine will continue to run if the PTO lever is
disengaged and the traction pedal is released, it is
strongly recommended that the engine be stopped
before rising from the seat.
To check the operation of the interlock switches,
perform the following procedure:
1. Drive the machine slowly to a large, relatively
open area. Lower the cutting unit, stop the
engine, and apply the parking brake.
2. Sit on the seat and depress the traction pedal.
Try to start the engine. The engine should
not crank. If the engine cranks, there is a
malfunction in the interlock system that should
be corrected before beginning operation.
3. Sit on the seat and start the engine. Rise from
the seat and move the PTO lever to On. The
PTO should not engage. If the PTO engages,
there is a malfunction in the interlock system
that should be corrected before beginning
operation.
4. Sit on the seat, engage the parking brake and
start the engine. Move the traction pedal out
of the neutral position. The engine should
kill. If the engine does not kill, there is a
malfunction in the interlock system that should
be corrected before beginning operation.
