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 oper-
ation.

Check Tire Pressure

Tires should be checked periodically to provide the opti-
mum traction and to guarantee the best cut (see Figure
16).
NOTE: These pressures may differ slightly from the
"Maximum Inflation" stamped on the side walls of the tires.
WARNING
Explosion Hazard
Never exceed maximum inflation stamped on the side-
walls of the tires.

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
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
When removing or installing battery cables,
disconnect the negative cable FIRST and recon-
nect it LAST. If not done in this order, the posi-
tive 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 (C, Figure 17).
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 17).
4. Coat the cable ends and battery terminals with petro-
leum jelly or non-conducting grease.
5. Be sure to replace the terminal cover (B, Figure 17)
over the positive battery terminal.
