CONTROLS
3. Motion Control Levers
The machine’s speed and direction are
continuously variable using the two steering
controls. The steering controls can be moved
forward or backward about a neutral 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.
8011-789
Steering controls
WARNING !
The machine can turn very
rapidly if one steering control
is moved much further forward
than the other.
If the steering controls are in uneven
positions when standing still or do not fit in
the slots for moving the controls outward,
they can be adjusted.
Tracking
If the mower is not tracking straight, check
the air pressure in both rear tires.
Recommended air pressure is 15 psi. (1 bar)
Tracking must be checked on a flat and level
concrete or blacktop surface. If the unit still
does not track straight contact your
Husqvarna workshop for adjustments.

The engine will run on a minimum of 85octane unleaded gasoline (no oil mix).
Environmentally adapted alkylate gasoline
can be used beneficially. See also Technical
Data concerning ethanol fuel. Methanol fuel is
not allowed.
WARNING!
Gasoline is highly flammable.
Observe caution and fill the
tank outdoors
(see the safety rules).
WARNING!
Fill to bottom of filler neck. Do
not overfill. Wipe off any
spilled oil or fuel. Do not store,
spill or use gasoline near an
open flame.

(0° C.), use fresh, clean winter grade gasoline
to help insure good cold weather starting.
8011-761
Fuel tank
IMPORTANT INFORMATION
Experience indicates that alcohol
blended fuels (called gasohol, ethanol or
methanol) can attract moisture which
leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine
while in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
the next season. See Storage
Instructions for additional information.
Never use engine or carburetor cleaners
in the fuel tank or permanent damage
may occur.
