Proper maintenance can prolong the life of
unit. The following chart shows the
recommended service schedule. More
frequent service may be required due to
working conditions (heavy loads, high
ambient temperatures, dusty conditions, or
airborne debris).
See the maintenance instructions in the
Engine Manual for additional information.
MAINTENANCE SCHEDULE
WARNING: AVOID INJURY. Read
and understand entire Safety
section before proceeding.
Interval Task Action
Each Use
Check Safety
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. See Safety Interlock System on
page 16.
Check Parking
Brake
Engage parking brake. Push unit. If unit rolls adjust parking
brake (see Parking Brake Adjustment on page 34).
Check Hydraulic
Oil Level
See Checking Hydraulic Oil Level on page 35.
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 39 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.
IMPORTANT: Do not spray the unit with water, especially when
the unit is warm from operation. Water can seep into bearings
and damage them.
NOTICE: Protect painted surfaces with automotive type wax.
Exhaust
Systems
Frequently clean dust and debris away from areas near and
around exhaust systems.
IMPORTANT: More frequent cleaning may be required in dusty
and drycontidions.
