Maintenance; Maintenance Schedule - Husqvarna 445 II Manuel D'utilisation

To cut trees and branches that are in tension
1. Figure out which side of the tree or branch that is in
tension.
2. Figure out where the point of maximum tension is.
(Fig. 92)
3. Examine which is the safest procedure to release the
tension.
Note: In some situations the only safe procedure is
to use a winch and not your product.
4. Keep a position where the tree or branch can not hit
you when the tension is released. (Fig. 93)
5. Make one or more cuts of sufficient depth necessary
to decrease the tension. Cut at or near the point of
maximum tension. Make the tree or branch break at
the point of maximum tension. (Fig. 94)
WARNING: Do not cut straight through a
tree or branch that is in tension.
WARNING: Be very careful when you
cut a tree that is in tension. There is a
risk that the tree moves quickly before or
after you cut it. Serious injury can occur

if you are in an incorrect position or if

6. If you must cut across tree/branch, make 2 to 3 cuts,
1 in. apart and with a depth of 2 in. (Fig. 95)

branch bends and the tension is released. (Fig. 96)

To use the product in cold weather
CAUTION: Snow and cold weather can
cause operation problems. Risk of too low
engine temperature or ice on the air filter
and the carburetor.
1. Clothe a part of the air intake on the starter. This
increases the engine temperature.
2. For temperatures below -5°C/23°F or in conditions
with snow, a winter cover is available. Assemble the
winter cover on the starter housing. The winter cover
decreases the flow of cool air and keeps snow away
from the carburetor space. (Fig. 97)
CAUTION: Remove the winter cover if
the temperature increases above -5°C/
23°F. Risk of too high engine
temperature and damage to the engine.
