Rider Maintenance Items
WARNING
Move the ground speed levers to START/PARK
positions, turn the mower blades OFF, turn the
ignition switch OFF, and wait for all moving parts
to stop before accessing the engine compartment
or performing any maintenance procedures.
ACCESSING THE ENGINE
COMPARTMENT
Lift up on the back edge of the seat deck to access the
engine compartment.
CLEAN DEBRIS FROM RIDER AND
ENGINE COMPARTMENT
Service Interval: Before each use.
CAUTION: If debris is not removed from the engine
compartment and other hot surfaces, it creates a fire
hazard. Before starting the unit at the beginning of the
mowing session, remove any grass clippings, dirt,
leaves, or other debris from the unit. Also clean out the
engine compartment.
CLEAN DEBRIS FROM ENGINE
COOLING AREAS AND AIR FILTER
Service Interval: Before each use.
CAUTION: If debris is not removed from the engine
compartment and other hot surfaces, it creates a fire
hazard. Before starting the unit at the beginning of the
mowing session, lift the seat deck and clean any debris
from the intake screen on top of the engine (A, Figure
13), exposed engine cooling fins, and around the air filter
assembly. Also open the air filter cover (B) and remove
any debris that has accumulated in the air filter
compartment.
CHECK TIRE PRESSURE
Service Interval: 25 Hours.
Tire pressure should be checked periodically, and
maintained at the levels shown in Figure 14. Note that
these pressures may differ slightly from the "Max
Inflation" stamped on the side-wall of the tires. The
pressures shown provide proper traction, improve cut
quality, and extend tire life.
