Personal Safety Equipment
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.
Make sure rst aid equipment is close at •
hand when using the machine.
Never use the machine when barefoot. •
Always wear protective shoes or boots,
preferably with steel toe caps.

hearing.
SAFETY
WARNING!
Never use the machine on terrain that
slopes more than 10 degrees.
Mow slopes side to side, not up
and down. Avoid sudden directional
changes.
Slope Operation
Slopes are a major factor related to loss of control or
machine tip-over accidents, which can result in severe
injury or death. Operation on all slopes requires extra
caution. If you cannot reverse up the slope or if you
feel unsure, do not mow it.
Mow across slopes (10 degrees maximum), •
not up and down.
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.
8011-670a
Personal protective equipment
Husqvarna-9
SAFETY
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 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.
Children
Tragic accidents can occur if the operator is not alert to
the presence of children. Children are often attracted
to the machine and the mowing activity. Never assume
that children will remain where you last saw them.
Keep children out of the mowing area and in •
the watchful care of a responsible adult other
than the operator.
Be alert and turn machine off if a child enters •
the area.

SAFETY
WARNING!
The engine must not be started when
the protective plate for the mower
deck’s drive belt is removed.
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 overll 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
overow.
8011-637
Never ll the fuel tank indoors
WARNING!
The engine and the exhaust system
become very hot during operation.
There is risk for burns if touched.

CONTROLS
Ignition Switch
The ignition key switch is located on the control panel
at the lower right.
WARNING!
The machine can turn very rapidly if
one steering control is moved much
further forward than the other.
Drive Levers
The machine’s speed and direction are continuously
variable using the two motion control levers.
By releasing both controls an equal amount the
machine moves in a straight line forward.
In order, for example, to turn right while moving
forward, squeeze the right control upward toward
the handle (neutral position). The rotation of the right
wheel is reduced and the machine turns to the right.
To stop forward travel, pull both drive levers up into the
neutral position.
When both controls are in the neutral position, the
machine stands still. The controls will be locked in
neutral position when both neutral locks are engaged.
