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 beginning •
repair work.
Keep all components in serviceable condition and •
make sure all nuts, bolts and other hardware are
tight. Replace worn or damaged decals.
Be careful when checking work tools. Use gloves •
when performing maintenance work.
Never allow persons not trained in the use of the •
machine to perform service on it.
Always park the machine on even ground before •
performing maintenance or making adjustments.
Do not disassemble the engine. This can •
invalidate the engine warranty. Contact the dealer
for 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 the
engine is run too fast, damage to the machine
components can occur.
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.
The mufer is designed to maintain sound levels 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 res or burn the user.
Never use a machine with a defective mufer.•
Reduce the risk of re by removing grass, leaves •
and other debris that may have caught in the
machine.

PROTECTION EQUIPMENT
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
fulls 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 sufcient 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.
