Section 4
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 alignment and wear after
the initial 2, 4, and 8 hours of operation. The belt
systems are self adjusting therefore tension
adjustment is not necessary.
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.
4.4 STARTING THE ENGINE
3. If the engine is cold, adjust the engine choke as
needed.
4. Adjust engine throttle control to about half engine
speed.
5. 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.
6. 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.
-IMPORTANT-
Start practice with a slow engine speed and slow
forward travel.
Do not push the steering control levers forward
when traveling forward. They are only used to
steer the mower and to travel in reverse by pulling
back on the levers.
Learn to operate the mower with the left hand on
the steering levers and the right hand on speed
control as shown in Figure 4-4. Using both hands
on the steering levers often causes overcontrol.
Learn to feather the steering controls to obtain a
smooth operating action. Jerky movements tend
to place extreme force on the drive pumps and
axles, as well as damage the lawns.
Practice operating the mower until you can make
it go exactly where you are aiming.
CAUTION:
WARNING:
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 on top of the
left fuel tank, is completely open. (See Section 7.4)
2. Sit in the operators seat and place the speed control
in the neutral position and engage the parking brake.
