Before each use or daily
Before each use remove any buildup of grass, dirt, or
other debris from the engine screen, engine exhaust,
and the area around the engine. This helps ensure
adequate cooling and correct engine speed and
reduces the possibility of overheating and mechanical
damage to the engine.
Brake Maintenance
Adjusting the Parking
Brake
Service Interval: Every 500 hours
Note:
Make sure to follow this procedure when a
brake component has been removed or replaced.
1.
Drive the machine onto a level surface.
2.
Disengage the blade-control switch (PTO), move
the motion-control levers to the N
position, and set the parking brake.
3.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
4.
Setup the machine to be pushed by hand. Refer
to
Using the Drive-Wheel-Release Valves (page
31).
5.
Raise the back of the machine up and support
the machine with jack stands.
CAUTION
Raising the machine for service
or maintenance relying solely on
mechanical or hydraulic jacks could be
dangerous. The mechanical or hydraulic
jacks may not be enough support or may
malfunction allowing the machine to fall,
which could cause injury.
Do not rely solely on mechanical
or hydraulic jacks for support. Use
adequate jack stands or equivalent
support.
6.
Engage and disengage the parking brake and
check each drive tire to ensure that each brake
engages and disengages.
7.
If an adjustment is necessary, disengage the
parking brake. Remove the cotter pin from the
brake linkage shaft
