Stihl HT 105 Instruction Manual page 9

If working on a slope, always stand uphill
or to the side of the branch which is to be
sawn. Watch out for rolling branches.
Note when reaching the end of a cut that
the power tool is no longer supported by
the guide bar in the cut. The user must
bear the weight of the machine – risk of
loss of control!
Always pull the power tool out of the cut
with the saw chain running.
Use the power tool for limbing and
pruning only, not for felling – Risk of
accidents!
Keep the saw chain away from any
foreign objects: Stones, nails, etc. may
be ejected and damage the saw chain.
If a rotating saw chain hits a stone or
another hard object, sparks may be
generated which may ignite easily
flammable materials under certain
conditions. Also dried-out plants and
brushwood are combustible, above all in
hot and dry weather. If there is a risk of
fire, do not use your pole pruner near
easily flammable materials, dry plants or
scrub. It is mandatory that you ask the
responsible forestry office about the
current fire hazard.
Before you leave the machine: Shut the
engine off.
Vibrations
Prolonged use of the power tool 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.
HT 105, HT 134, HT 135
The period of usage is prolonged by:
Hand protection (wearing warm
–
gloves)
Work breaks
–
The period of usage is shortened by:
Any personal tendency to suffer
–
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
Low outside temperatures.
–
The force with which the handles
–
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and Repairs
Service the machine regularly. Do not
attempt any maintenance or repair work
not described in the instruction manual.
Have all other work performed by a
servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer. STIHL dealers are
regularly given the opportunity to attend
training courses and are supplied with
the necessary technical information.
Only use high-quality replacement parts
in order to avoid the risk of accidents
and damage to the machine. If you have
any questions in this respect, consult a
servicing dealer.
STIHL recommends the use of genuine
STIHL replacement parts. They are
specifically designed to match your
model and meet your performance
requirements.
To reduce the risk of injury from
unintentional engine startup, always
shut off the engine and disconnect the
spark plug boot before performing any
repairs, maintenance or cleaning work. –
Exception: Carburetor and idle speed
adjustments.
Do not turn the engine over on the
starter with the spark plug boot or spark
plug removed since there is otherwise a
risk of fire from uncontained sparking.
To reduce the risk of fire, do not service
or store your machine near open flames.
Check the fuel filler cap for leaks at
regular intervals.
Use only a spark plug of the type
approved by STIHL and make sure it is
in good condition – see "Specifications".
Inspect the ignition lead (insulation in
good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire, do not operate
your machine if the muffler is damaged
or missing – there is also a risk of
hearing damage.
Do not touch a hot muffler since burn
injury will result.
Shut off the engine
before checking chain tension.
–
before retensioning the chain.
–
before replacing the chain.
–
before rectifying problems.
