Cutting Attachment - Stihl MS 150 TC Instruction Manual

Make sure your saw does not touch any
foreign materials: Stones, nails, etc. may
be flung off and damage the saw chain.
The saw may kick back unexpectedly –
risk of accidents.
If the rotating chain makes contact with
a rock or other solid object there is a risk
of sparking which may cause easily
combustible material to catch fire under
certain circumstances. Dry plants and
scrub are also easily combustible,
especially in hot and dry weather
conditions. If there is a risk of fire, do not
use your chainsaw near combustible
materials, dry plants or scrub. Always
contact your local forest authority for
information on a possible fire risk.
Warning! To avoid risk of
electrocution, take extra
precautions when cutting
near power lines. Have
the power switched off
before starting cutting
work in the immediate
vicinity of power lines.
Do not underbuck freely hanging limbs
because the chain may get pinched and
cause kickback and loss of control.
Take care when cutting scrub and young
trees. The saw chain may catch and
throw thin shoots in your direction.
To reduce the risk of injury, take special
care when cutting shattered wood
because of the risk of injury from slivers
being caught and thrown in your
direction.
After finishing a cut, activate the chain
brake to lock the chain or shut off the
engine before moving the saw to
another position in the tree.

Cutting techniques:
Always start the cut with the engine at
full throttle.
Always pull the saw out of the cut with
the chain running.
Cut straight through thin limbs
–
In case of thick limbs, first perform
–
relieving cut from below (approx. 1/5
of diameter), then buck from above
Support and secure heavy
–
branches with ropes.
If the saw gets pinched in the cut:
Shut off the engine and secure the
–
saw to the tree – in direction of
trunk.
Carefully free the saw from the cut,
–
using another saw if necessary.
Limbs under tension:
Always start relieving cut (1) at the
N
compression side (A).
Make relieving cut (1) and then
N
perform bucking cut (2) at the
tension side (B) – 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.

Cutting Attachment

A cutting attachment consists of the saw
chain, guide bar and chain sprocket.
The cutting attachment that comes
standard is designed to exactly match
the chain saw.

a
The pitch (t) of the saw chain (1),
–
chain sprocket and the nose
sprocket of the Rollomatic guide bar
must match.
The drive link gauge (2) of the saw
–
chain (1) must match the groove
width of the guide bar (3).
If non-matching components are used,
the cutting attachment may be damaged
beyond repair after a short period of
operation.
