OPERATING THE MACHINE
OPERATING A NEW MACHINE
How a new machine is operated and maintained will
determine the operating life of the machine.
A new machine just off the factory production line has
been tested, but the various parts are not accustomed
to each other, so care should be taken to operate the
machine for the first 50 hours at a slower speed and
avoid excessive work or operation until the various
parts become
“broken-in” . The manner in which the
machine is handled during the “breaking-in” period
greatly affects the life of your machine. Therefore, to
obtain the maximum performance and the longest
operating life of the machine, it is very important to
properly break-in your machine. In handling a new
machine, the following precautions should be observed.
1. Changing lubricating oil for new
machine
The lubricating oil is especially important in the case of
a new machine. The various parts are not
“broken-in”
and are not accustomed to each other. Small metal grit
may develop during the operation of the machine and
this may wear out or damage the parts. Therefore, care
should be taken to change the lubricating oil a little
earlier than it would ordinarily be required.
Details regarding normal service intervals can be found
in a different section.
(See SERVICE INTERVALS on page 40.)
2. Engine break-in
Z231BR-AU , Z251BR-AU
After the first 5 hours of operation, change the engine
oil.
Z231KH-AU , Z251KH-AU
No engine oil change.
(See SERVICE INTERVALS on page 40.)
Machine break-in
After the first 100 hours of operation, change the
transaxle fluid and oil filter.
(See EVERY 100 HOURS on page 53.)
DANGER
To avoid serious injury or death:
• Do not operate the mower without the discharge
deflector in the down position.
WARNING
To avoid serious injury or death:
• The machine relies upon the engine driven
transmission for speed, direction, and motion
control. If the engine is not running, the
machine cannot be driven or controlled.
If the engine stops when operating on a slope,
apply the parking brake immediately to prevent
a machine runaway.
• Do not allow anyone other than the driver to
ride on the machine.
• Do not drive the machine close to the edges of
ditches or banks which may collapse under the
weight of the machine, especially when the
ground is loose or wet.
• When making a turn, be sure to reduce the
travel speed and operate the motion control
levers carefully.
• To avoid tip-over accidents, operate across
slopes, not up and down. Avoid sudden starts
and stops on slopes. Slow down and use extra
caution when changing direction on a slope.
Park the machine on a firm and level surface.
• Watch where you are going at all times. Watch
for and avoid obstacles. Be alert at curbs, near
trees, and other obstructions and hidden
hazards.
• Do not mow near drop-offs, ditches or
embankments. The mower could turn over if a
wheel is over the edge of a cliff or ditch, or if an
edge caves in.
• Do not drive the machine on streets or
highways. Watch for traffic when you cross
roads or operate near roads.
• Look to the rear before and when backing. Make
sure the area immediately behind you is clear of
obstructions or holes, and small children. Use
extra caution when the machine is equipped
with a grass catcher.
• Keep bystanders, especially children, and
animals away from the mowing area.
• Clear the work area of objects which might be
picked up and thrown by the blades.
• Do not direct the opening of the discharge
deflector at bystanders or animals. Ejected
objects may cause injury. Plan your mowing
carefully before starting operation.
• Be sure to disengage the PTO and sit on the
operator's seat before starting the engine.
