from holes and hidden hazards.
Slope Operation
Slopes are a major factor related to loss of
control and tip-over accidents, which can
result in severe injury or death. Operation on
all slopes requires extra caution. If you
cannot back up the slope or if you feel
uneasy on it, do not mow it.
DO NOT operate on slopes of more than
20°. This maximum degree of operation is
without attachments.
Do not operate on slopes of more than 10°
with attachments such as grass catchers
installed.
Mow across slopes, not up and down.
DO NOT operate the mower on slopes at all
when the grass is wet.
DO NOT operate on slopes steeper than
you can feel secure about the traction of the
tires and the stability of the mower.
Watch for holes, ruts, bumps, rocks, or other
hidden objects. Uneven terrain could
overturn the machine. Tall grass can hide
obstacles.
Do not mow on moist or wet grass. Tires
may lose traction causing a loss of control.
Use extra care while operating machine with
grass catchers or other attachments; they
can affect the stability of the machine. Do
not use on steep slopes.
Slow down and use caution when making
turns and when changing directions on
slopes. Keep all movements on the slope
slow and gradual. Sudden changes in speed
or direction could cause the machine to roll
over.
Avoid starting, stopping, or turning on a
slope. If the tires lose traction, disengage
the blade(s) and proceed slowly straight
down the slope.
Operation on slopes may lead to loss of
steering control. When operating on slopes
be prepared to react to an emergency
situation:
• Return steering levers to neutral position.
• Immediately set parking brake.
• Turn off PTO and engine.
DO NOT try to stabilize the machine by
putting your foot on the ground.
DO NOT park on slopes unless necessary.
When parking on slope always chock or
block wheels. Always set parking brake.
Choose a low ground speed so you will not
have to stop or shift while on a slope.
Slow down and use extra care on hillsides.
Be sure to travel in the recommended
direction on hillsides. Turf conditions can
affect the machine’s stability. Use caution
while operating near drop-offs.
DO NOT operate near drop-offs, ditches, or
embankments. Unit can suddenly turn over if
a wheel is over the edge of a cliff or ditch, or
if an edge caves in.
Do not bypass transmission or allow
transmission to free-wheel when on a slope.

EN - 8
Fuel
To avoid personal injury or property damage,
use extreme care in handling gasoline.
Gasoline is extremely flammable and the
vapors are explosive.
Ethanol blends must not exceed E10. Higher
ethanol content may cause your
machine to run hotter and damage your
engine.
Replace fuel cap securely and clean up
spilled fuel before starting engine.
Extinguish all cigarettes, cigars, pipes, and
other sources of ignition.
Use only an approved fuel container.
Never store the machine or fuel container
where there is an open flame, spark, or pilot
light such as on a water or space heater or
other appliances.
Never fill containers inside a vehicle or on a
truck or trailer bed with a plastic liner.
Always place containers on the ground away
from your vehicle before filling.
Never refuel the machine indoors.
Never remove fuel cap or add fuel with the
engine running. Allow engine to cool before
refueling.
Fuel is highly flammable and its vapors are
explosive. Handle with care. Use only an
approved gasoline container with an
appropriately sized dispensing spout.
NO smoking, NO sparks, NO flames.
Remove equipment from the truck or trailer
and refuel it on the ground. If this is not
possible, then refuel such equipment with a
portable container, rather than from a
gasoline dispenser nozzle.
Keep the nozzle in contact with the rim of
the fuel tank or container opening at all
times until the fueling is complete. Do not
use a nozzle lock open device.
Never overfill fuel tank. Replace fuel cap
and tighten securely.
If fuel is spilled on clothing, change clothing
immediately.
DO NOT OVERFILL! This equipment and/or
its engine may include evaporative
emissions control system components,
required to meet EPA and/or CARB
regulations, that will only function properly
when the fuel tank has been filled to the
recommended level. Overfilling may cause
permanent damage to evaporative
emissions control system components.
Filling to the recommended level ensures a
vapor gap required to allow for fuel
expansion. Pay close attention while filling
the fuel tank to ensure that the
recommended fuel level inside the tank is
not exceeded. Use a portable gasoline
container with an appropriately sized
dispensing spout when filling the tank. Do
not use a funnel or other device that
obstructs the view of the tank filling process.
Towing
Do not attach towed equipment or
accessories.This vehicle is not designed to
tow.
Accessories
Follow the manufacturer’s recommendation
for wheel weights or counterweights
Attachments reduce the maximum operating
slope angle. DO NOT operate on slopes
over 10° when operating with attachments.
Check grass catcher components and the
discharge guard frequently and replace with
the manufacturer’s recommended parts,
when necessary.

evaporative emissions control system
components, required to meet EPA and/or
CARB regulations, that will only function
properly when the fuel tank has been filled to
the recommended level. Overfilling may
cause permanent damage to evaporative
emissions control system components. Filling
to the recommended level ensures a vapor
gap required to allow for fuel expansion. Pay
close attention while filling the fuel tank to
ensure that the recommended fuel level
inside the tank is not exceeded. Use a
portable gasoline container with an
appropriately sized dispensing spout when
filling the tank. Do not use a funnel or other
device that obstructs the view of the tank
filling process.
4. Replace fuel cap and tighten.
5. ALWAYS clean up spilled fuel.
GASOLINE
Use fresh unleaded fuel with an octane rating
of at least 87. DO NOT use E85 blended
fuels; the engine is not E20 / E30 / E85
compatible. The maximum recommended
ethanol content is 10%.
NOTICE: All gasoline is not the same. If the
engine experiences starting or performance
problems after using a new gasoline, switch
to a different fuel provider or fuel brand.
IMPORTANT: Excessively oxygenated or
reformulated fuels (fuels blended with
alcohols or ethers) can damage the fuel
system or cause performance problems. If
any undesirable operating problems occur,
use a gasoline with a lower percentage of
alcohol or ether.
