Safety
DANGER
DANGER
In certain conditions gasoline is extremely
flammable and vapors are explosive.
A fire or explosion from gasoline can burn
you, others, and cause property damage.
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite gasoline vapors. A fire or
explosion from gasoline can burn you and
others and cause property damage.
• Fill the fuel tank outdoors in an open
area, when the engine is cold. Wipe up
any gasoline that spills.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Never refill the fuel tank or drain the
machine indoors or inside an enclosed
trailer.
• Do Not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• Do Not fill the fuel tank completely
full. Add gasoline to the fuel tank until
the level is 1/4 to 1/2 inch (6–13 mm)
below the bottom of the filler neck. This
empty space in the tank allows gasoline
to expand.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• Never smoke when handling gasoline,
and stay away from an open flame or
where gasoline fumes may be ignited by
spark.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• Store gasoline in an approved container
and keep it out of the reach of children.
• If a gasoline dispenser nozzle must be
used, keep the nozzle in contact with the
rim of the fuel tank or container opening
at all times until fueling is complete.
• Add fuel before starting the engine.
Never remove the cap of the fuel tank or
add fuel when engine is running or when
the engine is hot.
WARNING
• If fuel is spilled, Do Not attempt to start
the engine. Move away from the area of
the spill and avoid creating any source of
ignition until fuel vapors have dissipated.
Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused
cancer in laboratory animals. Failure to use
caution may cause serious injury or illness.
• Do Not operate without entire exhaust
system in place and in proper working
condition.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas
tank/container opening.
• Keep away from eyes and skin.
• Never siphon by mouth.
6
Safety
• Check that the operator’s presence controls,
safety switches, and shields are attached and
functioning properly. Do Not operate unless they
are functioning properly.
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 buzzer sounds to prevent clogging of the
blower or deck.
Use a heavy-duty trailer or truck to transport the
machine. Lock brake and block wheels. Securely
fasten the machine to the trailer or truck with straps,
chains, cable, or ropes. Be sure that the trailer or truck
has all necessary lighting and marking as required by
law. Secure a trailer with a safety chain.
2. Disengage PTO, move speed control to neutral,
set park brake and dismount unit to dump hopper.
3. Make sure unit is on a dry level surface.
4. Lift the rear door up and allow it to rest on top
of hopper.
CAUTION
This unit does not have proper turn
signals, lights, reflective markings, or a
slow moving vehicle emblem. Driving on a
street or roadway without such equipment
is dangerous and can lead to accidents
causing personal injury. Driving on a street
or roadway without such equipment may also
be a violation of State laws and the operator
may be subject to traffic tickets and/or fines.
5. Dump hopper by firmly grasping one of the
hopper handles on either side of the unit and
lifting the hopper.
Clearing Hopper Screen
Screen may be removed by firmly lifting screen
handles (see Figure 5).
Pull screen towards the back to remove. Gently tap
debris from the screen as needed.
Do Not drive a unit on a public street or
roadway.

the front removable screen panel can be turned and
reinstalled under the primary screen to allow free air
flow from the hopper.
19
Operation
WARNING
Loading a unit on a trailer or truck increases
the possibility of tip-over. Tip-over could
cause serious injury or death.
• Use extreme caution when operating a
unit on a ramp.
• Use only a single, full width ramp; Do
Not use individual ramps for each side
of the unit.
• If individual ramps must be used, use
enough ramps to create an unbroken
ramp surface wider than the unit.
• Do Not exceed a 15° angle between ramp
and ground or between ramp and trailer
or truck.
• Avoid sudden acceleration while driving
unit on a ramp.
Loading a Unit
Use extreme caution when loading units on trailers
or trucks. One full width ramp is required. If it is
not possible to use one full width ramp, use enough
individual ramps to simulate a full width continuous
ramp.
Ramp should be long enough so that the angles
between the ramp and the ground and the ramp and
the trailer or truck do not exceed 15°. A steeper angle
may cause mower deck components to get caught as
the unit moves from ramp to trailer or truck. Steeper
angles may also cause the unit to tip. If loading on or
near a slope, position the trailer or truck so it is on
the down side of the slope and the ramp extends up
the slope. This will minimize the ramp angle. The
trailer or truck should be as level as possible.
Important: Do Not attempt to turn the unit
while on the ramp, you may lose control and
drive off the side.
Avoid sudden acceleration when driving on a ramp.

DANGER
Battery electrolyte contains sulfuric acid,
which is poisonous and can cause severe
burns. Swallowing electrolyte can be fatal or
if it touches skin can cause severe burns.
3. Clean all debris from around engine, drive belts,
and exhaust system area.
Remove Engine Shrouds and
Clean Cooling Fins
• Wear safety glasses to shield eyes, and
rubber gloves to protect skin and clothing
when handling electrolyte.
Service Interval: Every 80 hours
• Do Not swallow electrolyte.

All implied warranties of merchantability (that the
product is fit for ordinary use) and fitness for use (that the
product is fit for a particular purpose) are limited to the
duration of the express warranty.
Some states do not allow exclusions of incidental or
consequential damages, or limitations on how long an
implied warranty lasts, so the above exclusions and
limitations may not apply to you.
Instructions for Obtaining Warranty Service
The product must be registered with original proof of purchase
by an Exmark Service Dealer before obtaining any warranty
service.
Contact any Exmark Service Dealer to arrange service at their
dealership. To locate a dealer convenient to you, access our
website at www.exmark.com. U.S. or Canada customers may
also call 402-223-6375.
This warranty gives you specific legal rights, and you may
also have other rights which vary from state to state.
