To Cut Trees And Branches That Are In Tension; To Use The Product In Cold Weather - Husqvarna 439 Manual Del Usuario

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

7. Continue to cut more into the tree until the tree/
branch bends and the tension is released.
8. Cut the tree/branch from the opposite side of the
bend, after the tension is released.
