MAINTENANCE SCHEDULE

Action
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. See Safety
Interlock System on page 13.
Engage parking brake. Push unit. If unit rolls adjust parking
brake (see Parking Brake Adjustment on page 32).
See Checking Hydraulic Oil Level on page 33.
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 39 for correct tire pressure.
Clean engine, battery, seat, mower deck, etc. of dirt and
debris. Do not use solvents, hard cleaners, or abrasives.
IMPORTANT: 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.
Perform scheduled engine maintenance. Refer to Engine
Manual for detailed instructions.
GB - 20
