Check Tire Pressure

7).
NOTE:
These pressures may differ slightly from the “Maxi
-
mum Inflation” stamped on the side walls of the tires.
Check Mower Blade Stopping Time
WARNING
If the mower blade does not come to a complete stop
within 5 seconds, the clutch 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.

WARNING
U
nintentional 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.
