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 all movement on the slopes slow and gradual. Do not make sudden changes in speed or direction, which could cause the 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 your 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.

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 appliances.
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 your
vehicle when lling.
Remove gas-powered 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 fueling is complete. Do not use a nozzle lock­open 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, because the heat from the engine and the sun may otherwise
cause the fuel to expand and overow.
WARNING! The engine must not be started when the
driver’s oor plate or any protective plate for
the mower deck’s drive belt is removed.
