PROBLEMA CAUSA CORRECCIÓN
SOLUCIÓN DE PROBLEMAS - Vea la sección apropiada en el manual amenos que
esté dirigido a un centro de servico Husqvarna.
Cambie el envase de la gasolina si se emp-
ieza a oxidar. La oxidación y/o la mugre en
su gasolina producirán problemas.
Si es posible, guarde su unidad en un recinto
cerrado y cúbrala para protegerla contra el
polvo y la mugre.
Cubra su unidad con un forro protector
adecuado que no retenga la humedad. No
use plástico. El plástico no puede respirar, lo
que permite la formación de condensación,
lo que producirá la oxidación de su unidad.
IMPORTANTE: Nunca cubra la segadora
mientras el motor y las areas de escape todavia
estan calientes.
PRECAUCIÓN: Nunca almacene la
segadora con gasolina en el estanque dentro
de un edifi cio en donde los gases pueden
alcanzar una llama expuesta o una chispa.
Permita que se enfríe el motor antes de
almacenarla en algún recinto cerrado.

LAWN MOWER
Always observe safety rules when per-
form ing any main te nance.
TIRES
• Keep tires free of gasoline, oil, or insect
control chemi cals which can harm rubber.
Avoid stumps, stones, deep ruts, sharp
objects and other hazards that may
cause tire damage.
DRIVE WHEELS
Check rear drive wheels each time be fore
you mow to be sure they move freely.
The wheels not turning freely means trash,
grass cuttings, etc. are in the drive wheel area
and must be cleaned to free drive wheels.
If necessary to clean the drive wheels, be
sure to clean both rear wheels.
BLADE CARE
For best results, blade must be kept
sharp. Re place a bent or dam aged blade.
CAUTION: Use only a replacement
blade approved by the manufacturer of
your mower. Using a blade not approved
by the manufacturer of your mower is haz-
ardous, could damage your mower and
void your warranty.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Turn lawn mower on its side. Make
sure air fi lter and carburetor are up.
3. Use a wood block between blade and
mower hous ing to prevent blade from
turning when re mov ing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth.
4. Remove blade bolt by turning counter-
clockwise.
5. Remove blade & attaching hard ware
(bolt, lock wash er & hardened wash er).
TO REPLACE BLADE
1. Position blade on the blade adapter
aligning the two (2) holes in the blade
with the raised lugs on the adapter.
2. Be sure the trailing edge of blade (oppo-
site sharp edge) is up toward engine.
3. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
4. Use block of wood between blade and
lawn mower housing and tighten the
blade bolt, turning clockwise.
The recommended tightening torque is
35-40 ft. lbs.
IMPORTANT: Blade bolt is heat treated.
If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts
section of this manual.

TO SHARPEN BLADE
NOTE: We do not recommend sharp-
en ing the blade - but if you do, be sure the
blade is balanced. An un bal anced blade
will cause eventual damage to mower or
engine.
The blade can be sharp ened with a fi le
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail ex posed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
GRASS CATCHER
The grass catcher may be hosed with
water, but must be dry when used.
Check your grass catcher often for dam-
age or de te ri o ra tion. Through normal
use it will wear. If catcher needs replac-
ing, replace only with ap proved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
GEAR CASE
To keep your drive system working
properly, the gear case and area around
the drive should be kept clean and free
of trash build-up. Clean under the drive
cover twice a season.
The gear case is fi lled with lubricant to
the proper level at the factory. The only
time the lubricant needs attention is if
service has been performed on the gear
case.
If lubricant is required, use only Texaco
Starplex Pre mi um 1 Grease, Part No.
750369. Do not substitute.
