4. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, move the PTO switch to the
OFF (down) position, and start the engine. With the
engine running, engage the PTO switch to the ON
(up) position, and rise slightly off of the seat. The
engine should shut off.
5. Sit in the seat in the operating position, engage the
parking brake, place the steering control levers in
the neutral lock position, move the PTO switch to the
OFF (down) position, and start the engine. With the
engine running, move either steering control lever
out of the neutral lock position. The engine should
shut off. Repeat for the other steering control lever.
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.
4.4 INITIAL RUN-IN PROCEDURES
FIRST DAY OF USE OR APPROXIMATELY 20 HOURS
1. Check all belts for proper alignment and wear at 2, 4
and 8 hours.
2. Change the engine oil and oil filter after the first 20
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. Adjust pressure if necessary.
(See Section 7.10.)
4.5 STARTING THE ENGINE
CAUTION
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 behind and to
the left of the operator's seat, is completely open.
2. Sit in the operator’s seat and place the steering
control levers in the neutral position.
3. Engage the parking brake.
4. Place the PTO switch in the disengaged position.
5. If the engine is cold, choke the engine as needed.
6. Move the engine throttle control to about half engine
speed.
7. 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.
8. Allow engine to warm before operating the mower.
4.6 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.
Learn the operation on flat ground before operating
on slopes.
Start practicing with a slow engine speed and slow
forward travel.
Learn to feather the steering controls to obtain a
smooth operating action.
