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.
Mow up and down slopes (10 degrees maximum),•
not across.
Watch for holes, ruts, bumps, rocks, or other•
hidden objects. Uneven terrain could overturn the
machine. Tall grass can hide obstacles.
Choose a low ground speed so that you will not•
have to stop while on the slope.
Do not mow on wet grass. Tires may lose traction.•
Avoid starting, stopping, or turning on a slope. If•
the tires lose traction, disengage the blades and
proceed slowly straight down the slope.
Keep movement on the slopes slow and gradual.•
Do not make sudden changes in speed or
direction, which could cause machine to roll over.
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.•
Do not try to stabilize the machine by putting a foot•
on the ground.
Do not mow near drop-offs, ditches, or•
embankments. The machine could suddenly roll
over if a wheel is over the edge or if the edge
caves in.
WARNING!
When using the machine, approved personal protective equipment (shown in illustrations)
shall be used. Personal protective equipment cannot eliminate the risk of injury but it
will reduce the degree of injury if an accident does happen. Ask your retailer for help in
choosing the right equipment.
WARNING!
Do not drive up or down hills with
slopes greater than 10 degrees. And
do not drive across any slopes.

Safe Handling of Gasoline
To avoid personal injury or property damage, use
extreme care in handling gasoline. Gasoline is
extremely ammable and the vapors are explosive.
Extinguish all cigarettes, cigars, pipes, and other•
sources of ignition.
Use only approved gasoline container.•
Never remove gas cap or add fuel with the engine•
running. Allow engine to cool at least two (2)
minutes before refueling.
Never fuel the machine indoors.•
Never store the machine or fuel container where•
there is an open ame, spark, or pilot light such as
on a water heater or other appliance.
Before you begin refueling, minimize the risk of•
static electricity by touching a metal surface.
Never ll containers inside a vehicle or on a •
truck or trailer bed with plastic liner. Always place
containers on the ground away from the vehicle
when lling.
Remove gas-powered equipment from the truck•
or trailer and refuel it on the ground. If this is not
possible, 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 fueling
is complete. Do not use a nozzle lock-open device.
If fuel is spilled on clothing, change clothing•
immediately.
Never overll fuel tank. Replace gas cap and •
tighten securely.
Do not start the engine near spilled fuel.•
Never use gasoline as a cleaning agent.•
If leaks arise in fuel system, engine must not be•
started until problem has been resolved.
Check the fuel level before each use and leave•
space for the fuel to expand, as the heat from the
engine and the sun may otherwise cause the fuel
to expand and overow.

Controls in neutral locked position
Furthermore, there is a neutral position, which is
locked if the steering controls are moved outward.
When both controls are in the neutral position (N), the
machine stands still.
By moving both controls an equal amount forward
or backward, the machine moves in a straight line
forward or backward respectively.
In order, for example, to turn right while moving
forward, move the right control towards the neutral
position. The rotation of the right wheel is reduced and
the machine turns to the right.
Zero turn can be achieved by moving one control
backward (behind the neutral position) and carefully
moving the other steering control forward from its
neutral position. The rotation direction when zero
turning is determined by which steering control is
moved backward behind the neutral position. If the left
steering control is pulled backward, the machine turns
to the left. Use extra care when using this maneuver.
If the steering controls are in uneven positions when
standing still or do not t in the slots for moving the
controls outward, they can be adjusted.
