Section 4
4.2 SAFETY INTERLOCK SYSTEM
The mower is equipped with a safety interlock system
that prevents the engine from starting unless the deck
drive is disengaged and the speed control is in neutral.
The interlock system shuts off the engine if the operator
leaves the seat with the speed control not in the neutral
position and/or the cutter blades are engaged. It will also
shut the engine off if the cutter deck drive is engaged and
the hopper is raised.
4.4 STARTING THE ENGINE
DO NOT USE STARTING FLUIDS. Use of starting
fluids in the air intake system may be potentially
explosive or cause a “runaway” engine condition
that could result in engine damage and/or personal
injury.
1. Be sure the fuel shutoff valve, located under the fuel
tank, is completely open. (See section 7-4.)
2. Sit in the operator’s seat and place the speed control
in the neutral position.
3. Engage the parking brake.
4. If the engine is cold, adjust the engine choke as
needed.
5. Adjust engine throttle control to about half engine
speed.
6. Turn the ignition key to the START position and
release the key as soon as the engine starts. Do not
hold the key in the START position for more than 15
seconds at a time. Allow at least 60 seconds between
each cranking attempt to prevent overheating of the
starter motor. Prolonged cranking can damage the
starter motor and shorten battery life.
7. Allow engine to warm before operating the mower.
4.5 GROUND TRAVEL AND STEERING
-IMPORTANT-
If you are not familiar with the operation of a
machine with lever steering and/or hydrostatic
transmissions, the steering and ground speed
operations should be learned and practiced in
an open area, away from buildings, fences, or
obstructions. Practice until you are comfortable
with the handling of the machine before
attempting to mow. Learn the operation on flat
ground before operating on slopes.
CAUTION:
WARNING:
Never operate the mower with the interlock
system disconnected or malfunctioning. Do not
disengage or bypass any switch; injury to
yourself and others or property damage could
result.
4.3 INITIAL RUN-IN PROCEDURES (First
Day of Use or Approximately 10 Hours)
1. Check all belts for proper tension at 2, 4 and 8 hours.
2. Change the engine oil and oil filter after the first 5
hours of operation. (See Section 7.4.)
3. Check hydraulic oil level in reservoir. (See Section
7.3.)
4. Check for loose hardware. Tighten as needed.
5. Check interlock system for proper operation. (See
Section 4.2.)
6. Check tire pressure. Inflate tires if necessary.
