Mowing Tips
Observe and mark rocks and other xed objects in •
order to avoid collisions.
Properly level the cutting deck for best mowing •
performance. The blades should be parallel to the
ground or slightly tipped down in the front.
Use only sharp blades.•
Check tire pressure. Different pressure can cause •
uneven mowing results.
Use the left hand side of the deck for trimming.•
Mow so 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
rst two patterns in opposite direction.
Begin with a high cutting height and reduce it until •
the desired mowing result is attained.
Cut the average lawn to 2½" (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 15 cm •
(6") in height should be mowed twice. Make the
rst cut relatively high; the second to the desired
height.
Use a high engine speed (the blades rotate •
rapidly) and low ground speed (the machine
moves slowly) for the best mowing results. If the
grass is not too long and dense, the ground speed
can be increased without noticeably depreciating
the mowing result.
Mow often to obtain the nest lawn. Mowing •
becomes more even and grass clippings more
evenly distributed over the mown area. The total
time taken is not increased, as a higher driving
speed can be used without inferior mowing results.
Avoid mowing wet lawns. The mowing result is •
inadequate because the wheels sink into the soft
lawn. Clumps build and the grass clippings will
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.
Do not spray water directly on a hot mower. Allow •
it to cool to a safe temperature before cleaning.

LUBRICATION
Cables
If possible, grease both ends of the cables and move
the controls to end stop positions when lubricating.
Ret 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 light engine oil until the oil
begins to escape from the bottom.
Tip: 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.
Front Wheel Mount1.
Lubricate with a grease gun, one zerk for each wheel
mount, until the grease is forced out. Use only good
quality bearing grease. Grease from well-known brand
names (petrochemical companies) usually maintains a
good quality.
Front Wheel Bearings2.
Lubricate with a grease gun, one zerk for each set of
wheel bearings, until the grease is forced out. Use only
good quality disulphide grease.
Throttle and Choke Cables3.
Lubricate the cable ends at the carburetor with the oil
can. Move the controls to the end points and lubricate
again.

STORAGE
Winter Storage
At the end of the mowing season (or if it will not be
in use for longer than 30 days), the machine should
be readied for storage. 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 as regards to
the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage
container. Always use the mixing ratios specied 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 ames, sparks,
or a pilot light such as in a boiler, hot
water tank, clothes drier, etc. Handle
the fuel with care. It is very ammable
and can cause serious personal injury
and property damage. Drain the fuel
into an approved container outdoors
and far away from open ame. Never
use gasoline for cleaning. Use
a degreaser and warm water instead.
To ready the machine for storage, follow these steps:
Thoroughly clean the machine, especially 1.
under the mower deck. Touch up damage
to the paint and spray a thin layer of oil on
the underside of the mower deck to avoid
corrosion.
Inspect the machine for worn or damaged 2.
parts and tighten any nuts or screws that may
have become loose.
Change the engine oil; dispose of used oil 3.
properly.
Empty the fuel tanks or add a fuel stabilizer. 4.
Start the engine and allow it to run until the
carburetor is drained of fuel or the stabilizer
has reached the carburetor.
Remove the spark plug and pour about a 5.
tablespoon of engine oil into the cylinder.
Turn over the engine so that the oil is evenly
distributed. Ret the spark plug.
Lubricate all grease zerks, joints, and axles.6.
Store the machine in a clean, dry place and 7.
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 checkup at an authorized service workshop
is a good way to ensure that the machine performs its
best the following season.
