1.
Ensure that the parking brake is set. Remove your foot
from the traction pedal and ensure that it is in neutral.
2.
Move the throttle control to the mid-idle position.
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.
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.
Engine Cooling Fan Operation
The engine cooling fan switch has two positions for
controlling the operation of the fan. The two positions are R
and Auto. The fan has the ability to reverse to blow debris
off of the rear screen. Under normal operating conditions,
the switch will be in the Auto position. In Auto, the fan speed
will be controlled by the coolant or hydraulic oil temperature
and will automatically reverse to blow debris off of the rear
screen. A reverse cycle is automatically initiated when either
the coolant or hydraulic temperature reaches a certain point.
By pressing the fan switch forward into the R position, the
fan will complete a manually initiated reverse cycle. It is
recommended to reverse the fan when the rear screen is
clogged or prior to entering the shop or the storage area.
Checking the Interlock
Switches
CAUTION
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 the
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.
5.
Sit on the seat, start the engine and set speed range to
low. Move PTO switch forward to engage cutting units.
Important:
The center lift lever must momentarily
be pushed to the lower position to enable PTO
circuit actuation by PTO switch.
•
Raise either wing cutting unit to the transport position.
The cutting unit should turn off. If the cutting unit does
not stop, there is a malfunction in the interlock system
that should be corrected before resuming operation.
•
If the wing cutting unit is lowered again the motor should
re-start. If the cutting unit does not re-start, there is
