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.
Check Tire Pressure
Tires should be checked periodically to provide the
optimum traction and to guarantee the best cut (see Figure
7).
NOTE: These pressures may differ slightly from the
"Maximum Inflation" stamped on the side walls of the tires.
