SAFETY INSTRUCTIONS
Fuel system
W ARNING!
Gasoline and gasoline fumes are
poisonous and extremely flammable.
Be especially careful when handling
gasoline, as carelessness can result
in personal injury or fire.
• Only store fuel in containers approved for that
purpose.
• Never remove the fuel cap and fill the fuel tank
when the engine is running.
• Always stop the engine when refueling.
• Do not smoke when filling the gasoline tank and
do not pour gasoline in the vicinity of sparks or
open flame.
• Never fill the fuel tank indoors.
• Before starting the machine after refueling, it
should be moved at least 10 feet (3 M) from
the location where it was filled.
• Turn off the fuel supply for storage or transport.
• If leaks arise in the fuel system, the engine must
not be started until the problem has been
resolved.
8011-205chg
Never fill the fuel tank indoors.
FUEL VALVE
8011-186
Close the fuel valve.
• Check the fuel level before each use and leave
space for the fuel to expand, because the heat
from the engine and the sun can otherwise
cause the fuel to expand and overflow .
• Avoid overfilling. If you spill gasoline on the
machine, wipe up the spill and wait until it has
evaporated before starting the engine. If you
spill gasoline on your clothing, change your
clothing.
12
8011-222chg
Fueling always poses an element of risk.
SAFETY INSTRUCTIONS
Maintenance
• Never make adjustments with the engine
running.
• Disengage the drive units, shut off the engine
and wait until all moving parts come to a
complete stop before making adjustments,
performing maintenance or cleaning the
machine.
• Disconnect the spark plug cable before

the machine to perform service on it.
• Always park the machine on even ground before
performing maintenance or making
adjustments.
8011-027

W ARNING!
Wait until all moving part s are completely
still before performing maintenance on
the machine.
• Do not disassemble the engine. This can
invalidate your engine warranty. Contact your
dealer if you have any questions regarding
service or guarantee matters. Follow all
maintenance instructions.
• Do not change the setting of governors and
avoid running the engine with overly high RPM.
If you run the engine too fast, you risk damaging
the machine components.
• Do not modify safety equipment. Check
regularly to be sure it works properly. The
machine must not be run with defective or
disassembled safety equipment.

at an approved level and keep direct exhaust
away from the user. Exhaust gases from the
engine are extremely hot and may contain
sparks that can cause fires or burn the user.
• Never use a machine with a defective muffler .
• Reduce the risk of fire by removing grass,
leaves and other debris that may have caught
in the machine.
Turn off the engine and remove the
spark plug cable.
8011-210chg
Keep the machine clean.

PROTECTIVE EQUIPMENT
Personal equipment
Consult your Husqvarna dealer when selecting
protective equipment. Our 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 in many
cases need to cut back the object with a power
saw. Hence, it is appropriate to use personal
protective equipment that fulfils 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 gives sufficient
protection when using a power saw. Thus when
using the stump grinder, we recommend using
both a wire mesh visor to protect your face and
protective glasses. Alternatively, you can use a
Plexiglas face guard, but it scratches more easily
and is more susceptible to soiling and fogging.
You require the following personal protective
equipment:
1. Protective helmet (hard hat)
2. Ear protection
3. Face guard
4. Protective trousers
5. Protective glasses
6. Breathing protection (risk of dusty work
environment)
7. Protective gloves
8. First aid kit
9. Protective boots or steel-toed shoes
