2. Pull the choke lever out to the On position (when
starting a cold engine) and the throttle lever to the
Slow position.
Important:
When operating the machine in
temperatures less than 32°F (0°C) allow the
machine time to warm up before using. This
prevents damage to the hydrostat and the
traction loop.
3. Insert the key into the ignition switch and rotate it
clockwise to start the engine. Release the key when
the engine starts. Regulate the choke to keep the
engine running smoothly.
Important:
To prevent overheating of the
starter motor, do not engage the starter longer
than 10 seconds. After 10 seconds of continuous
cranking, wait 60 seconds before engaging the
starter motor again.
Important:
When the engine is started for the
first time, or after an overhaul of the engine,
operate the machine in forward and reverse for
1 to 2 minutes. Also operate the lift lever to be
sure of proper operation of all parts.
4. To stop the engine, move the throttle control to the
Slow position and rotate the ignition key to Off.
Engage the parking brake and remove the key from
the switch to prevent accidental starting.
5. Close the fuel shutoff valve before storing the
machine.
CAUTION
Shut the engine off and wait for all moving
parts to stop before checking for oil leaks, loose
parts, and other malfunctions.
Checking the Interlock System
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 purpose of the interlock system is to prevent the
engine from cranking or starting unless the traction
pedal is in the neutral position.
1. Check the interlock operation in a wide open area
free of debris and bystanders. Stop the engine.
2. Sit on the seat and engage the parking brake.
3. Depress the traction pedal in forward and reverse
while trying to start the engine.
4. If the engine cranks, there may be a malfunction in
the interlock system. Repair it immediately.
5. If the engine does not crank, the system is operating
correctly.
6. With the operator in the seat, traction pedal in
neutral and parking brake on, the engine should
start. Lift off the seat and slowly depress the
traction pedal, the engine should stop in one to
three seconds. Correct problem if not operating
properly.
7. With the operator on the seat, the parking brake
engaged and the engine running, Depress the
traction pedal in forward and reverse. The engine
should stop within 2 seconds. If the engine does not
stop, there may be a malfunction in the interlock
system. Repair it immediately. If the engine does
stop, the system is operating correctly.
Towing the Machine
In case of emergency, the machine can be towed for a
short distance. However, we do not recommend this
as a standard procedure.
Important:
Do not tow the machine faster than
2–3 MPH (3–5 km/h) because the drive system
may be damaged. If the machine must be moved
a considerable distance, transport it on a truck
or trailer. The tires may lock up if the machine
is towed too fast. If this occurs, stop towing the
machine and wait for the traction circuit pressure
to stabilize before resuming towing at a slower
speed.
Break-in Period
Only 8 hours of operating time is required for the
break-in period.
Since the first hours of operation are critical to future
dependability of the machine, monitor its functions
and performance closely so that minor difficulties,
which could lead to major problems, are noted and can
be corrected. Inspect the machine frequently during
break-in for signs of oil leakage, loose fasteners, or any
other malfunction.
Operating Characteristics
Refer to the attachment operator’s manual for specific
operating instructions for the attachment.
