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.

Slope Operation
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.
Figure 3
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 on slopes greater than 15 degrees, near
drop-offs and water.
DANGER
3. Water
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.
• Remove or mark obstacles such as rocks, tree
limbs, etc. from the mowing area. Tall grass can
hide obstacles.
• Do Not mow slopes when grass is wet.
• Do Not mow near drop-offs or near water.
• Watch for ditches, holes, rocks, dips and rises that
change the operating angle, as rough terrain could
overturn the machine.
• Do Not mow slopes greater than 15
degrees.
• Avoid sudden starts when mowing uphill because
the mower may tip backwards.
• Reduce speed and use extreme caution
on slopes.
• Be aware that operating on wet grass, across steep
slopes or down hill may cause the mower to lose
traction. Loss of traction to the drive wheels may
result in sliding and loss of braking and steering.
• Avoid sudden turns or rapid speed
changes.
• Keep the roll bar in the raised and locked
position and use seat belt.
• 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.
