WARNING!
Wait until all moving parts are
completely still before performing
maintenance on the machine. Turn
off the engine and remove the spark
plug cable.

PROTECTION EQUIPMENT
14 - HUSQVARNA
Personal Protection Equipment
Consult your Husqvarna dealer when selecting
protective equipment. Dealers have a broad
assortment of equipment for professionals (such as
forestry workers) and knowledge about occupational
environment requirements and protective levels.
Before using the stump grinder, you may need to
cut back the object with a power saw. It is therefore
practical to use personal protective equipment that
fulls requirements for working with both stump
grinders and power saws.
The main difference is that you should wear protective
glasses when operating the stump grinder while the
wire mesh visor is sufcient when using a power saw.
Thus when using the stump grinder, it is recommended
to use both a wire mesh visor to protect your face
and protective glasses. A Plexiglas face guard is an
alternative, but has been found to scratch easily and is
susceptible to soiling and fogging.
You require the following personal protective
equipment:
Protective helmet (hard hat)1.
Ear protection2.
Face guard3.
Protective trousers4.
Protective glasses5.
Breathing protection (dusty work environment)6.
Protective gloves7.
First aid kit8.
Protective boots or steel-toed shoes9.

Starter
The magnapull-type starter has spring return. To
replace the return spring or starter cord, contact an
authorized service workshop.
Starter Handle
Misuse of the starter handle can damage the starter.
Do not twist the starter cord around your hand.
Pull out the handle slowly until the gears mesh. Do not
pull out the starter cord completely and do not let go of
the starter handle when extended.
8011-127
IMPORTANT INFORMATION
Do not let the recoil cord snap back by itself.
This may damage the cord or the recoil
starter assembly.
WARNING!
Do not run the engine indoors, in
enclosed or poorly ventilated spaces.
Engine exhaust fumes contain
poisonous carbon monoxide.
8060-024
Choke Control
The choke control opens and closes the choke valve in
the carburetor. This is only used to start a cold engine.
If the engine is warm, the control should be in the far
right position.
If the engine is cold, place the lever completely or
partly to the left. Move the lever back to the right once
the engine starts. Forgetting the choke is evident if the
engine runs roughly and produces black smoke.
This also results in increased fuel consumption.
Fuel Valve
The fuel valve opens and closes the connection
between the tank and the carburetor. The illustration
shows the tank valve closed; to open, turn the lever
completely to the right. There is no middle position.
Turn off the valve when the machine is not in use
to avoid ooding the carburetor. The fuel valve is
combined with a sludge reservoir.

Air Filter
The engine air lter consists of a cyclone lter and a
ne lter.
Air is drawn in through the screen (1) on the cyclone
lter and coarser pollutants collect in the container (2).
The ne lter, consisting of a foam rubber pre-lter and
a paper lter cartridge, is located under the cowling
(3). The cowling and the cyclone lter can be removed
by removing the wing nut (4).
See Replacing the Air Filter in the Maintenance section
for cleaning instructions.
Running the machine with a dirty air lter will cause
the engine to run on partial choke and show the same
symptoms as a closed choke described above. It can
also be difcult to start. 8011-126
