Interlock System See Parking Brake Interlock System on page 12.
Check Hydraulic Fluid Check hydraulic oil level mark on cap/dipstick. Add
20W50 engine oil as needed. Do not overfill. See
Check Hydraulic Fluid Level on page 19.
Check Tires See Specifications on page 31 for correct tire
pressure.
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.
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.
NOTE: Protect painted surfaces with automotive
type wax.
