Logs under strain:
Risk of pinching! Always start relieving
cut (1) at compression side.Then make
bucking cut (2) at tension side. If the saw
pinches, stop the engine and remove it
from the log.
Only properly trained professionals
should work in an area where the logs,
limbs and roots are tangled. Working in
"blow down" areas is extremely
hazardous. Drag the logs into a clear
area before cutting. Pull out exposed
and cleared logs first.
Felling
Felling is cutting down a tree.
Before felling a tree, consider carefully
all conditions which may affect the
direction of fall.
MS 171, MS 181, MS 181 C, MS 211, MS 211 C
WARNING
There are a number of factors that may
affect and change the intended direction
of fall, e.g. wind direction and speed,
lean of tree, surrounding trees and
obstacles, sloping ground, one-sided
limb structure, wood structure, decay,
snow load, etc. To reduce the risk of
severe or fatal injury to yourself or
others, look for these conditions prior to
beginning the cut, and be alert for a
change in direction while the tree is
falling.
WARNING
Always observe the general condition of
the tree. Inexperienced users should
never attempt to cut trees that are
decayed or rotted inside or that are
leaning or otherwise under tension.
There is an increased risk that such
trees could snap or split while being cut
and cause serious or fatal injury to the
operator or bystanders. Also look for
broken or dead branches which could
vibrate loose and fall on the operator.
When felling on a slope, the operator
should stand on the uphill side if
possible.

When felling, maintain a distance of at
least 2 1/2 tree lengths from the nearest
person.
When felling in the vicinity of roads,
railways and power lines, etc., take extra
precautions. Inform the police, utility
company or railway authority before
beginning to cut.
WARNING
The noise of your engine may drown any
warning call.
