Husqvarna 325HE4 Operator's Manual page 9

In countries that have a warm and dry climate there is a
significant risk of fire. We therefore fit certain mufflers with
a spark arrestor mesh. Check whether the muffler on your
machine is fitted with this kind of mesh.
For mufflers it is very important that you follow the
instructions on checking, maintaining and servicing your
machine.
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to
the machine.
If the muffler on your machine is fitted with a spark
arrestor mesh this must be cleaned regularly. A blocked
mesh will cause the engine to overheat and may lead to
serious damage.
WARNING! Mufflers fitted with catalytic
!
converters get very hot during use and
remain so for some time after stopping.
This also applies at idle speed. Contact
can result in burns to the skin.
Remember the risk of fire!
GENERAL SAFETY PRECAUTIONS
WARNING! The inside of the muffler
!
contain chemicals that may be
carcinogenic. Avoid contact with these
elements in the event of a damaged
muffler.
WARNING! The exhaust fumes from the
!
engine are hot and may contain sparks
which can start a fire. Never start the
machine indoors or near combustible
material!
Blades
Turn off the motor. Disconnect the HT lead from the spark
plug.
To ensure good cutting results it is important that the
contact pressure between the blades is correct. The
contact pressure is adjusted by turning the screws on the
underside of the bar clockwise as far as they will go. Then
turn the screws anticlockwise a 1/4 turn. Lock the screws
using the locking nut on the top of the bar. Check that the
screws are loose enough to allow the washers under the
screw heads to slide sideways.
When the blades are correctly adjusted the play between
the blades should be 0,2–0,4 mm, measured at the
screws.
The edges of the blades are too hard to be filed. Dull
blades should be sharpened using a grinder.
Replace the blades if they are bent or damaged.
Gear
The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear
housing.
