SAFETY INSTRUCTIONS
Driving on Slopes
Driving on slopes is one of the operations
where the risk is greatest that the driver will
lose controlor the machine willtip over,which
can result in serious injury or death. All
slopes require extra caution. If you cannot
reverse up a slope or if you feel unsure,
do not mow the slope.
Do as follows
• Remove obstacles such as stones,
tree branches, etc.
• Watch out for and avoid driving over
furrows, holes, and bumps. On uneven
terrain, the machine can tip more easily.
Long grass can hide obstacles.
• Mow up and down, not side-to-side.
• If machine stops while going uphill,
disengage blades and back down slowly.
• Drive evenly and slowly. Use small
movements of the steering controls.
• Be extra cautious with any additional
equipment, which can alter the
machine’s stability.
Do not
• Do not make sudden changes in speed
or direction.
• Do not drive the machine on terrain that
slopes more than 10°.
• Do not mow near verges, ditches, or
banks. The machine can suddenly spin
around if a wheel goes over the edge of
adroporditch,orifanedgegivesway.
• Do not mow wet grass. It is slippery,and
the tires can lose their grip, so that the
machine slides.
• Avoid unnecessary turns on slopes, and
if it proves necessary, turn slowly and
gradually downward, if possible.
8011-634
Mow up and down, not side-to-side
8011-635
Be extra cautious when driving on slopes
• Avoid starting or stopping on a slope. If
the tires begin to slip, shut down the
bladesand drive slowly straightdown the
slope.
English-9
SAFETY INSTRUCTIONS
Children
• Serious accidentsmay occur if you fail to
be on guard for children in the vicinity of
the machine.Children are often attracted
to the machine and mowing work. Never
assume that children will stay put where
you last saw them.
• Keepchildrenawayfromthemowing
area and under close supervision by
another adult.
• Keep an eye out and shut off the
machine if children enter the work area.
• Beforeand during a reversing maneuver,
look backward and downward for small
children.
• Never allow a child to ride with you.
They can fall off and injure themselves
seriously or prevent risk-free
maneuvering of the machine.
• Never allow children to operate the
machine.
• Be particularly cautious near corners,
bushes, trees, or other objects that block
your view.

SAFETY INSTRUCTIONS
Maintenance
WARNING!
The engine must not be started when the protective plate for the mower deck’s
drive belt is removed.
• Stop the engine. Prevent the engine from
startingby removing the spark plug cables from
the spark plugs or by removing the ignition key
before making any adjustments or performing
maintenance.

• If leaks arise in the fuel system, the engine
must not be started until the problem has been
resolved.
• Store the machine and fuel in such a way that
there is no risk of leaking fuel or fuel vapor
leading to damages.
• 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 overflow.
• Avoid overfilling. If you spill fuel on the
machine, wipe up the spill and wait until it has
evaporated before starting the engine. If you
have spilled fuel on your clothing, change your
clothing.

1. Recoil Starter Grip
IMPORTANT INFORMATION
Do not let recoil cord snap back by itself.
This may damage the cord or the recoil
starter assembly.
Pull the recoil starter grip slowly until you feel
compression, then pull it briskly.
Normally this engine will not backfire. If you
get backfires, contact your Husqvarna dealer
for service.
2. Ground Speed Lever
Located in the center of the console. Controls
the forward speed of the mower. Push the
lever forward if you want to go faster, pull it
back to go slower or pull it all the way back to
the stop postion.
To begin motion, the operator must move the
ground speed lever forward before
disengaging the neutral lock bail.
Ground Speed Lever Stop is the adjustment
screw placed on the front edge of the driver´s
panel. It is used to insure ground speed lever
does not over travel drive levers into reverse.

3. Motion control levers
The machine’s speed and direction are
continuously variable using the two motion
control levers.
When both controls are in the neutral position,
the machine stands still. The controls can be
locked in neutral position by the Neutral bail
By moving both controls an equal amount the
machine moves in a straight line forward.
WARNING !
The machine can turn very
rapidly if one steering control
is moved much further than the
other.
In order, for example, to turn right while
moving forward, move the right control
towards the handle (neutral position). The
rotation of the right wheel is reduced and the
machine turns to the right.

5. Operator Presence Lever
Located on the handle. As an additional
safety feature, these mowers are equipped
with an Operators Presence System. This is
an electrical interlock safety system which is
activated by depressing either one or both of
the Operator Presence Levers at the handle
grips.
Releasing both Operators Presence Levers
while mowing or transporting will break the
electrical circuit and cause the engine and
mower to stop. The mower will not stop
immediately after releasing the O.P. levers,
some travel does occur.
One or both levers must be pressed against
the handle for the engine to remain running,
when the blades are engaged or neutral lock
bail is not locked in drive levers.
8011-661

6. Throttle Control
The throttle control regulates the engine
speed and thereby the rate of rotation of the
blades, assuming the control switch for
engaging the mower deck is pulled out, see
Engaging the Mower Deck.
In order to increase or decrease the engine
speed, the control is moved forward or
backward respectively.
Avoid idling the engine for longer periods, as
there is a risk of the spark plugs fouling.

1. Drive, used when operating the machine.
2. Parking, parking brake applied.
3. Bypass, used when moving the machine
by hand.

Parking Brake
The parking brake on IZT machines is applied
when the Brake/Bypass lever is set in
position 2. The parking brake must only be
used to brake a machine which is standing
still. Be careful if you release the parking
brake on sloping ground. The machine is
heavy and can move uncontrolled, especially
if the lever is set to the bypass position (3).
8. Blade Engagement Switch
In order to engage the blades, pull the knob
out. The blades are disengaged when the
knob is depressed.
