CHAIN SHARPENING
N
FIG. dalla 2 alla 10
#
Disconnect the cord from the mains supply.
#
Wear protective gloves.
#
Ensure the chain is correctly tensioned and not
too loose.
#
Engage the chain brake (10) to block the
chain on the bar when sharpening.
#
Use a round file for chain sharpening,
diameter equivalent to 1.1 times the cutting
tooth depth.
#
File at a horizontal angle, 35° to the bar.
#
File from inside towards outside of the tooth
only.
#
Sharpen each tooth equally by using the
same number of strokes.
#
File at an angle of 90° to the bar.
#
Check the safety depth gauge height every
5 chain sharpenings. Use depth gauge
measuring instrument to check the height of
the depth gauge.
12.GENERAL SUGGESTIONS FOR
CUTTING
We suggest to cut utilizing the bottom of the
bar, this way of operating diminishes the
probability of injuring. Be careful when cutting
with the top of the bar.
CUTTING LOGS
Cutting a log resting on the two extremities
N
FIG. 11
#
First cut 1/3 of a diameter from the top.
Next cut from below using the top of the bar. This
will avoid pinching of the bar in wood. Avoid
touching the ground with the bar.
Cutting from a saw horse

FIG. 12
#
First cut 1/3 of a diameter from below.
Next cut from the top using the bottom of
the bar.
FELLING A TREE
#
Before felling a tree, consider carefully all
conditions including the intended direction of
the fall, the natural lean of the tree, surrounding
trees and obstacles, the wind direction and speed.
Directional cut
N
FIG. 13
#
Cut a wedge (1/3-1/2 of tree diameter) out
of the trunk on the side which you want the
tree to fall.
Felling cut
N
FIG. 14
#
Cut into the trunk from the other side 1"- 2"/3-6
cm above the wedge.
#
Use a felling wedge to help control felling and
prevent binding the guide bar and saw chain in
the cut.
#
Safety distance is 2.5 times the height of the tree
to fell. Be sure that nobody is in the danger zone
before and during the felling.
CUTTING PREPARED TIMBER
#
When cutting prepared, use clamps or shocks
to secure wood.
