Operation
WARNING
Operating engine parts, especially the muffler,
become extremely hot. Severe burns can occur
on contact and debris, such as leaves, grass,
brush, etc. can catch fire.
• Allow engine parts, especially the muffler, to
cool before touching.
• Remove accumulated debris from muffler and
engine area.
• Install and maintain in working order a
spark arrester before using equipment
on forest-covered, grass-covered, or
brush-covered unimproved land.
WARNING
Engine exhaust contains carbon monoxide,
which is an odorless deadly poison that can kill
you.
Do Not run engine indoors or in a small confined
area where dangerous carbon monoxide fumes
can collect.
WARNING
Operating a Navigator tractor without an
approved Exmark front mount attachment
increases the possibility of operator entanglement
in drive wheels or forward tip over. Entanglement
or tip-over could cause serious injury or death.
When operating a Navigator tractor without
an approved Exmark front mount attachment,
observe the following:
• Keep feet and clothing away from tires.

install a different front mount attachment.

keeping away from holes and hidden hazards.
• Be sure all drives are in neutral and parking brake
is engaged before starting engine.
• Never raise deck with blades running.
• Never operate the mower with damaged guards,
shields, or covers. Always have safety shields,
guards, switches and other devices in place and in
proper working condition.
• Never mow unless there is a grass collection
system or mulch kit in place and working properly.
• Do Not change the engine governor setting or
overspeed the engine.
• Park machine on level ground. Stop engine, wait
for all moving parts to stop, remove key and
engage parking brake:
