ENGINE
See Dealer Annually to
Inspect muffler and spark arrester
Replace spark plug
Replace fuel filter
Clean engine air cooling system
* Whichever comes first
** Clean more often in dusty conditions or when airborne
debris is present.
Checking Tire Pressures
Tire pressure should be checked periodically (see Figure 17),
and maintained at the levels shown in the Specifications
chart. Note that these pressures may differ slightly from the
"Max Inflation" stamped on the side-wall of the tires. The
pressures shown provide proper traction and extend tire life.
Check Mower Blade Stopping Time
Mower blades and mower drive belt should come to a
complete stop within five seconds after the electric PTO
switch is turned off.
WARNING
Unsafe Operation Hazard
If the mower blade does not come to a complete stop within
5 seconds, the blade must be adjusted. Do not operate the
machine until the proper adjustment has been performed by
an authorized dealer.
Check the mower blade for proper function. See Safety
Interlock System Tests. The blade should stop rotating in 5
seconds or less after moving the blade control to the OFF
position.
Battery Maintenance
WARNING
Explosion and Fire Hazard
When removing or installing battery cables, disconnect the
negative cable FIRST and reconnect it LAST. If not done in
this order, the positive terminal can be shorted to the frame
by a tool.
Cleaning the Battery and Cables
1. Disconnect the cables from the battery, negative cable
first (B, Figure 18).
2. Clean the battery terminals and cable ends with a wire
brush until shiny.
3. Reinstall the battery and reattach the battery cables,
positive cable first (A, Figure 18).
4. Coat the cable ends and battery terminals with petroleum
jelly or non-conducting grease.
5. Be sure to replace the terminal cover over the positive
battery terminal (A, Figure 18).
Charging The Battery
WARNING
Explosion and Fire Hazard
Keep open flames and sparks away from the battery; the
gasses coming from it are highly explosive. Ventilate the
battery well during charging.
A dead battery or one too weak to start the engine may be
the result of a defect in the charging system or other electrical
component. If there is any doubt about the cause of the
problem, see your dealer.
To charge the battery, follow the instructions provided by the
battery charger manufacturer as well as all warnings included
in the Operator Safety section of this manual. Charge the
battery until fully charged. Do not charge at a rate higher than
10 amps.
Seat And Ground Speed Lever
Adjustments
The seat and ground speed levers should be adjusted so
that the ground speed levers can be moved through their full
range of motion without contacting the operator’s legs.
Seat Adjustment
1. Raise the seat.
2. Loosen the adjustment hardware (A or B, Figure 19,
depending on seat type) under the seat base.
3. Slide the seat forward or backward to the desired
position.
4. Tighten the hardware to 80 lb-in (9 Nm).
Ground Speed Lever Adjustment
1. Loosen the ground speed lever mounting hardware (A,
Figure 20) to adjust the levers forward and backward.
2. Remove the hardware to raise or lower the levers.
3. Always be sure to adjust both levers so that they are
aligned (B, Figure 20).
4. After adjustment is complete, tighten the hardware to 13
lb-ft (18 Nm).
Speed Balancing (Tracking) Adjustment
If the rider drifts to the right or left when the ground speed
levers are in the maximum forward position, the top speed of
each of these levers can be balanced. Only adjust the speed
of the wheel that is traveling faster.
1. Tighten the knob (A, Figure 21) of the faster wheel by 1/2-
turn (clockwise) increments until the rider travels (tracks)
straight.
