See Parking Brake Interlock System on page 12.
Check Hydraulic Fluid
Check hydraulic oil level mark on the expansion
tank. Add 20W50 engine oil as needed. Do not
overfill. See Check Hydraulic Fluid Level on
page 21.
Check Tires
See Specifications on page 36 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.
NOTE: Protect painted surfaces with automotive
type wax.
IMPORTANT: Do not spray the unit with water,
especially when the unit is warm from operation.
Water can seep into bearings and damage them.
