Emissions Control
Maintenance, replacement, or repair of the emissions control
devices and systems may be performed by any non-road
engine repair establishment or individual. However, to obtain
"no charge" emissions control service, the work must be
performed by a factory authorized dealer. See the Emissions
Warranty.
Check Mower Blade Stopping Time
WARNING
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.

Check Tire Pressure
Tires should be checked periodically to provide the optimum
traction and to guarantee the best cut (see Figure 3).
NOTE: These pressures may differ slightly from the "Maximum
Inflation" stamped on the side walls of the tires.
WARNING
Unintentional sparking can result in fire or electric
shock.
Unintentional start-up can result in entanglement,
traumatic amputation, or laceration.
Before performing adjustments or repairs:
•
Disconnect the spark plug wire and keep it away from the
spark plug.
•
Disconnect battery at negative terminal (only engines with
electric start).
•
Use only correct tools.
•
Do not tamper with governor spring, links, or other parts
to increase engine speed.
•
Replacement parts must be of the same design and
installed in the same position as the original parts. Other
parts may not perform as well, may damage the unit, and
may result in injury.
•
Do not strike the flywheel with a hammer or hard object
because the flywheel may shatter during operation.
