– Watch for limbs which are under
tension.
– Never attempt to cut several limbs
at once.
When cutting small logs
– Use a sturdy and stable support –

Always start relieving cut at the
compression side (1).
Make relieving cut and then perform
bucking cut at the tension side (2) –
the saw will otherwise pinch or kick
back.
If not otherwise possible, make the
bucking cut from the bottom upwards
(underbuck) – be wary of pushback.
Do not cut a lying log at a point where it
is touching the ground because the saw
chain will otherwise be damaged.
Vibrations
Prolonged use of the unit may result in
vibration-induced circulation problems in
the hands (whitefinger disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
– Hand protection (wearing warm
gloves)
– breaks
The period of usage is shortened by:
– Any personal tendency to suffer
from poor circulation (symptoms:
frequently cold fingers, itching).
– Low outside temperatures.
– Gripping force (a tight grip hinders
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear, seek medical advice.
