Stihl HS 87, Instruction Manual

Page: 6 / 24

If the hedge is very dusty or dirty, spray the cut‐
ting blades with STIHL resin solvent from time to
time during cutting. This will significantly reduce
blade friction, the aggressive effects of sap and
the build-up of dirt particles.
The dust which is generated during operation
may be harmful to health. Wear a respirator in
very dusty conditions.
Before you leave the machine: Shut the engine
off.
Check the cutting blades at regular short inter‐
vals during operation or immediately if there is a
noticeable change in cutting behavior:
–
Shut off the engine
–
Wait for cutting blades to come to a standstill
–
Check the condition and firm seat, watch out
for fine cracks
–
Ensure that the cutting blades are sharp
Always clean plant residue, chips, leaves and
excess lubricant off the engine and muffler – risk
of fire!
2.8 After finishing work
Always clean dust and dirt off the machine – do
not use any grease solvents for this purpose.
Spray the cutting blades with STIHL resin sol‐
vent. Run the motor briefly so that the solvent is
evenly distributed.
2.9 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.
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 cir‐
culation (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.
2.10 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 per‐
formed by a servicing dealer.
STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized 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
power tool. If you have any questions in this
respect, consult a servicing dealer.
STIHL recommends the use of original STIHL
replacement parts. They are specifically
designed to match your model and meet your
performance requirements.
To reduce the risk of injury, always shut off the
engine before 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 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.
Vibration behavior is influenced by the condition
of the AV elements – check the AV elements at
regular intervals.
