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

Mowing Tips

OPERATION

• 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.

• 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 l ooking lawns,
mow often after moderate growth.

For best cutting performance, grass over
6" (15 cm) i n 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 t oo 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.

WARNING!
Clear the lawn of stones and

other objects that can be
thrown out by the blades.

8011-409

Mowing patterns

English-28

OPERATION

• 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 spray high 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.

8011-514

Clean mower deck after each use

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 a sticky residue that can foul the
carburetor and disrupt engine function.

Fuel stabilizers are an acceptable option as
regards 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 tighten any 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. 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.
