Stihl MSE 170 C Instruction Manual page 10

English
Be especially careful with small,
–
tough limbs, undergrowth and
offshoots – the saw chain may
become caught in them
Never cut several limbs at once
–
Do not lean too far forward
–
Do not cut above shoulder height
–
Use extreme caution when re-
–
entering a previous cut
Do not attempt plunge cuts if you
–
are not experienced in this cutting
technique
Be alert for shifting of the log or
–
other forces that may cause the cut
to close and pinch the chain
Always cut with a correctly
–
sharpened, properly tensioned saw
chain – the depth gauge setting
must not be too large
Use low-kickback saw chains as
–
well as narrow-radius guide bars
Pull-in (A)
When the chain on the bottom of the bar
– overbucking – is suddenly pinched,
caught or encounters a foreign object in
the wood, the chain saw may suddenly
8
be drawn forward toward the log – to
avoid this, engage the bumper spike
firmly in the wood.
Pushback (B)
When the chain on the top of the bar –
underbucking – is suddenly pinched,
caught or encounters a foreign object in
the wood, the chain saw may suddenly
be driven straight back toward the
operator – to avoid this:
Do not allow the top of the guide bar
–
to become jammed
Do not twist the guide bar in the cut
–
Be very careful
With freely hanging limbs
–
With trunks that are under tension
–
between other trees because they
fell unfavourably
When working in windbreaks
–
A
In these cases, do not use a chain saw –
use a hoist, winch or dragline instead.
Pull out trunks that are lying about and
have been cut free. Whenever possible,
deal with them in open areas.
Dead wood (brittle, rotten or dead wood)
poses a significant, highly unpredictable
hazard. It is extremely difficult or even
practically impossible to recognise the
danger. Use aids such as winches or
draglines.
When felling close to roads, rail lines,
power lines, etc., work with particular
care. If necessary, notify police, power
companies or railway authorities.
