Using The Unit - Stihl HT 56 C Instruction Manual

English
To reduce the risk of injury, always shut off the
enginebefore carrying out any maintenance or
repairs or cleaning the machine. – Exception:
Carburetor and idle speed adjustments.
Do not turn the engine over on the starter with
the spark plug boot or spark plug removed
unless the slide control / stop switch is on STOP
or 0 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 inter‐
vals.
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 con‐
dition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to hearing,
do not operate your machine if the muffler is
damaged or missing.
Do not touch a hot muffler since burn injury will
result.
Stopping the engine
– before checking chain tension.
– before retensioning the chain.
– before replacing the chain.
– before rectifying problems.
Observe sharpening instructions – keep the
chain and guide bar in good condition at all times
for safe and correct handling of the saw. The
chain must be properly sharpened, tensioned
and well lubricated.
Always change the chain, guide bar and sprocket
in good time.
Store fuel and chain lubricant in properly label‐
led, safety-type canisters only. When handling
gasoline, avoid direct contact with the skin and
avoid inhaling fuel vapour – health risk.

3.2 Cutting sequence
To allow branches to free fall, always cut the
lower branches first. Prune heavy branches
(large diameter) in several controllable pieces.
WARNING
Never stand directly underneath the branch you
are cutting – be wary of falling branches. – Note
that a branch may spring back at you after it hits
the ground – risk of injury.
3.3 Disposal
Do not throw cuttings into the garbage can – they
can be composted.
3.4 Working technique
Hold the control handle with your right hand, and
the shaft with your left hand. Your left arm should
be extended to the most comfortable position.
Always hold the shaft with your left hand in the
area of the handle hose.
The shaft should always be held at an angle of
60° or less.
The least tiring working position is a tool angle of
60°.
Any lesser angle may be used to suit the situa‐
tion.
