Interlock
System
WARNING: Safety interlock system failure and
improper operation of unit can result in death or
serious injury. Test this system each time the unit is
operated. If this system does not function as
described, do not operate until repairs are made.

Check Tires
CAUTION: Avoid injury! Explosive separation of tire
and rim parts is possible when they are serviced
incorrectly:
•
Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
•
Do not inflate the tires above the recommended
pressure.
•
Do not weld or heat a wheel and tire assembly. Heat
can cause an increase in air pressure resulting in an
explosion. Welding can structurally weaken or deform
the wheel.
•
Do not stand in front or over the tire assembly when
inflating. Use a clip-on chuck and extension hose long
enough to allow you to stand to one side.
See SPECIFICATIONS on page 40 for correct tire pressure.
Clean Unit
Clean engine, battery, seat, mower deck, etc. of dirt and
debris. Do not use solvents, hard cleaners, or abrasives.
Do not spray the unit with water, especially when the unit is
warm from operation. Water can seep into bearings and
damage them.
NOTE: Protect painted surfaces with automotive type wax.
