Safety  
DANGER  
DANGER  
In certain conditions gasoline is extremely  
flammable and vapors are explosive.  
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.  
A fire or explosion from gasoline can burn  
you, 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.  
• Check that the operator’s presence controls,  
safety switches, and shields are attached and  
functioning properly. Do Not operate unless they  
are functioning properly.

can occur on contact and debris, such as  
leaves, grass, brush, etc. can catch fire.  
• Never mow with the discharge deflector raised,  
removed or altered unless there is a grass  
collection system or mulch kit in place and  
working properly.  
• Allow engine parts, especially the muffler,  
to cool before touching.  
• Do Not change the engine governor setting or  
overspeed the engine.  
• Remove accumulated debris from muffler  
and engine area.  
• Stop engine, wait for all moving parts to stop,  
remove key and engage parking brake:  
• Install and maintain in working order a  
spark arrester before using equipment  
on forest-covered, grass-covered, or  
brush-covered unimproved land.  
– Before checking, cleaning or working on the  
mower.  
– After striking a foreign object or abnormal  
vibration occurs (inspect the mower for  
damage and make repairs before restarting  
and operating the mower).  
WARNING  
Engine exhaust contains carbon monoxide,  
which is an odorless deadly poison that can  
kill you.  
– Before clearing blockages.  
– Whenever you leave the mower.  
• Stop engine, wait for all moving parts to stop, and  
engage parking brake:  
Do Not run engine indoors or in a small  
confined area where dangerous carbon  
monoxide fumes can collect.  
– Before refueling.  
– Before dumping the grass catcher.  
WARNING  
WARNING  
Operating a FrontRunner tractor without an  
approved Exmark front mount attachment  
increases the possibility of forward tip over.  
Tip-over could cause serious injury or death.  
Hands, feet, hair, clothing, or accessories can  
become entangled in rotating parts. Contact  
with the rotating parts can cause traumatic  
amputation or severe lacerations.

without an approved Exmark front mount  
attachment, observe the following:  
• Do Not operate the machine without  
guards, shields, and safety devices in  
place and working properly.  
• Limit operation to minimum required to  
install a different front mount attachment.  
• Keep hands, feet, hair, jewelry, or clothing  
away from rotating parts.  
• Minimize speed and use extreme caution.  
• Only operate on a flat level surface.  
NEVER carry passengers. DO NOT operate  
the mower when people, especially children, or  
pets are in the area.  
• Do Not operate up or down a trailer ramp.  
• Avoid sudden acceleration or deceleration.  
• Be alert, slow down and use caution when making  
turns. Look behind and to the side before  
changing directions.  
• Operate only in daylight or good artificial light,  
keeping away from holes and hidden hazards.  
• Stop the blades, slow down, and use caution when  
crossing surfaces other than grass and when

Slope Operation  
Figure 3  
Use Extreme caution when mowing and/or turning  
on slopes as loss of traction and/or tip-over could  
occur. The operator is responsible for safe operation  
on slopes.  
1. Safe Zone-Use the mower here on slopes less than 15  
degrees  
2. Danger Zone-Use a walk behind mower and/or hand  
trimmer near drop-offs and water.  
3. Water  
DANGER  
• Remove or mark obstacles such as rocks, tree  
limbs, etc. from the mowing area. Tall grass can  
hide obstacles.  
Operating on wet grass or steep slopes can  
cause sliding and loss of control. Wheels  
dropping over edges, ditches, steep banks, or  
water can cause rollovers, which may result  
in serious injury, death or drowning.  
• Watch for ditches, holes, rocks, dips and rises that  
change the operating angle, as rough terrain could  
overturn the machine.  
• Do Not mow slopes when grass is wet.  
• Do Not mow near drop-offs or near water.  
• Avoid sudden stops when mowing downhill  
because the mower may tip forwards.  
• Do Not mow slopes greater than 15  
degrees.  
• Be aware that loss of traction may occur going  
uphill. Weight transfer to the rear wheels may  
cause drive wheels to slip and cause loss of  
braking and steering.  
• Reduce speed and use extreme caution  
on slopes.  
• Avoid sudden turns or rapid speed  
changes.  
• Always avoid sudden starting or stopping on a  
slope. If tires lose traction, disengage the blades  
and proceed slowly off the slope.  
• See inside the back cover to determine the  
approximate slope angle of the area to be mowed.  
• Follow the manufacturer’s recommendations for  
wheel weights or counter weights to improve  
stability.  
• Use a walk behind mower and/or a hand trimmer  
near drop-offs, ditches, steep banks or water.  
(Figure 3).  
• Use extreme care with grass catchers or  
attachments. These can change the stability of the  
machine and cause loss of control.
