Driving on Slopes

Driving on slopes is one of the operations
where the risk is greatest that the driver will
lose controlor the machine will tipover,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 motion control levers.

• Be extra cautious with any additional

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

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 the 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.

OPERATION

Operation

Read “Safety Instructions” on page 7 and following pages, if you are unfamiliar with the machine.

Training

Walk behind mowers are far more manueverable t han typical riding mowers due to their unique steering
capabilities.

We recommend that this section be reviewed in it’s entirety prior to attempt to move mower under its own
power.Additionally, we suggest when first operating mower, use a reduced throttle speed and reduced
ground speed by NOT moving motion control levers t o thefurthest forward or reverse positions duringinitial
operation, or until operation becomes comfortable with controls. We also suggest first time users, or new
users to Walk behind mowers become familiar wi th the mowers movement on a hard surface, such as
concrete or blacktop PRIOR to attempting to operate on turf. Until operator becomes comfortable with
mower controls and steering capability, they may damage turf due to over aggresive maneuvers.

To move fo rw ard and backward

The direction and speed of the mowers movement is effected by the movement of the motion control
lever(s). The left control lever controls the left wheel motor. The right control the right wheel motor.

IMPORTANT INFORMATION
When control levers are in the reverse

position they return to neutral when
released, this may cause the mower to
suddenly stop.

First time users should push mower (see "Moving Machine by Hand" on page 34) to an open, flat area,
without other persons or vehicles/obstaclesnear by.In order to move unitunder itsown power, the operator
must start engine (see "Before Starting" on page 25), adjust engine speed to idle, disengage neutral bail
park brake, do not engage (turn on) blades at this time. As long as the control levers have been out of
neutral position the mower will not move. Slowly move both control levers forward sligthly,this will allow the
mower to start moving forward in a straight line. Pull back on control levers to neutral position and mower
should stop moving. Pull back slightly on control levers, this will allow mower to start moving backwards or
in the reverse direction. Let the control l evers get to the neutral position and mower should stop moving.

To turn to the right

While moving in a forward direction, pull the right lever back towards the neutral position while maintaining
the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in
that direction.

To turn to the left

While moving in a forward direction, pull the left lever back towards the neutral position while maintaining
the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in
that direction.

WARNING!
Be thoroughly familiar with all

controlstheir function andhow
to operate them before
operating the mower.

To zero turn

While moving in a foward direction, first pull both control levers back until the m ower stops dramatically.
Then turn by alternating one lever slightly to the forward position and the other in the reverse position.

To start an engine with a weak
battery

WARNING!
Lead-acid batteries generate

explosive gases. Keep sparks,
flame and smoking materials
away from batteries. Always
wear eye protection when
around batteries.

If your battery is too weak to start the engine,
it should be recharged. (See “Battery” on
page 37).

If “jumper cables” are used for emergency
starting, follow this procedure:

IMPORTANT IN FORMATION
Your mower is equipped with a 12-volt

negative grounded system. The other
vehicle must also be a 12-volt negative
grounded system. Do not use your mower
battery to start other vehicles.

To attach jumper cables

• Connect each end of the RED cable to
the POSITIVE (+) terminal on each
battery, taking care not to short against
chassis.

• Connect one end of the BLACK cable to
the NEGATIVE (-) terminal of the fully
charged battery.

• Connect the other end of the BLACK
cable to a good CHASSIS GROUND,
away from the fuel tank and battery.

IMPORTANT IN FORMATION
Do not allow the units to touch each other.

To remove cables, reverse order

• DisconnectBLACK cable first from chassis and
then from the fully charged battery.

• Disconnect RED cable last from both batteries.

OPERATION

To operate on hills

To operate on slopes is a dangerous mowing
job. Read the Safety Instructions section
“Driving on Slopes” on page 9.

WARNING!
Do n

ot drive up or down hills
with slopes greater than 10
degrees. And do not drive
across any slopes.

• The slowest speed possible should be
used before starting up or down hi lls.

• Avoid stopping or changing speed on
hills.

• Make all turns slowly.

Mowing Tips

• Observe and mark rocks and other fixed
objects in order to avoid collisions.

• The cutting deck should be properly
leveled for best mowing performance.
The blades should be parallel to the
ground or slightly tipped down in the
front.

• Only use sharp blades.

• Check tire pressure. Different pressure
can cause uneven mowing results.

• The left hand side of the deck should be
used for trimming.

• Drive so that clippings are discharged
onto the area that has been cut. Have
the cut area to the right of the mower.
This will result in more even distribution
of clippings and a more uniform cut. To
avoid clippings spraying on roads etc,
mow the first two patterns in opposite
direction.

WARNING!
Clear the lawn of stones and

other objects that can be
thrown out by the blades.

English-30

8011-409

Mowing patterns

OPERATION

• Begin with a high cutting height and
reduce it until the desired mowing result
is attained.

The average lawn should be cut to 2 1/2"
(64 mm) during the cool season and to
over 3" (76 mm) during the hot months.
For healthier and better looking lawns,
mow often after moderate growth.

For best cutting performance, grass over
6" (15 cm) in height should be mowed
twice. Make the first cut relatively high;
the second to the desired height.

• The mowing result will be best with a
high engine speed (the blades rotate
rapidly) and l ow speed (the machine
moves slowly).If the grass is not too long
and dense, the driving speed can be
increased without noticeably
depreciating the mowing result.

• The finest lawns are obtainedby mowing
often. The m owing becomes more even
and the grass clippings more evenly
distributedover the mown area. The total
time taken is not increased as a higher
drivingspeed can beused without poorer
mowing results.

• Avoid mowing wet lawns. The mowing
result is poorer because the wheels sink
into the soft lawn, clumps build, and the
grass clippings fasten under the cowling.

• Hose the mower deck with water after
each use. Hose especially underneath.

• Do not sprayhigh pressure spray directly
on top of spindles.

• Avoid getting engine too wet.

WARNING!
Never drive the machine on

terrain that slopes more than
10°.
Mow sl opes up and down,
never side-to-side. Avoid
sudden directional changes.

LUBRICATION

Lubricating the Cables

If possible, lubricate both ends of the cables and move the controls to end stop positions when lubricating.
Refit the rubber covers on the cables after lubrication. Cables with sheaths will bind if they are not
lubricated regularly. If a cable binds, it can disrupt operation.

If a cable binds, remove the cable and hang it vertically. Lubricate it with thin engine oil until the oil begins
to escape from the bottom.

Hint!: Fill a small plastic bag with oil and tape it so that it seals against the sheath and allow the cable to
hang vertically from the bag overnight. If you do not succeed in lubricating the cable, it must be replaced.

STORAGE

Storage

Winter Storage

At the end of the mowing season, the machine
should be readied for storage (or if it will not be in
use for longer than 30 days). Fuel allowed to
stand for long periods of time (30 days or more)
can leave sticky residues that can plug the
carburetor and disrupt engine function.

Fuel stabilizers are an acceptable option to
prevent sticky residues during storage. Add
stabilizer to the fuel in the tank or in the storage
container. Always use the mixing ratios specified
by the manufacturer of the stabilizer. Run the
engine for at least 10 minutes after adding the
stabilizer so that it reaches the carburetor. Do not
empty the fuel tank and the carburetor if you have
added stabilizer.

WARNING!
Never store an engine with fuel

in the tank indoors or in poorly
ventilated spaces where fuel
vapor can come in contact with
open flames, sparks, or a pilot
light such as in a boiler, hot
water tank, clothes drier, etc.
Handle the fuel with care. It is
very flammable and careless
use can cause serious personal
injury and property damage.
Drain the fuel into an approved
container outdoors and far
away from open flame. Never
use gasoline for cleaning. Use
a degreaser and warm water
instead.

To ready the machine for storage, follow these
steps:

1. Thoroughly clean the machine, especially
under the mower deck. Touch up damage to
the paint and spray a thin layer of oil on the
undersideof the mower deck in order to avoid
corrosion.

2. Inspect the machine for worn or damaged
partsand tightenany nuts or screws that may
have become loose.

3. Change the engine oil; dispose of properly.

4. Empty the f uel tanks or add a fuel stabilizer.
Start the engine and allow it to run until even
the carburetor is drained of fuel or the
stabilizer has reached the carburetor.

5. Remove the spark plugs and pour about a
tablespoon of engine oil into each cylinder.
Turn over the engine so that the oil is evenly
distributed and then refit the spark plugs.

6. Lubricate all grease zerks, joints, and axles.

7. Remove the battery.Clean, charge, and store
the battery in a cool place, but protect i t from
direct cold.

8. Store the machine in a clean, dry place and
cover it for extra protection.

Service

When ordering spare parts, please specify the
purchase year, model, type, and serial number.

Always use genuine Husqvarna spare parts.
An annual check-up at an authorized service

workshop is a good way to ensure that your
machine performs i ts best the following season.
