injury from the rakes and tines moving while the

engine is idling.
Keep the rakes and tines clear of foreign objects

– such objects may be caught and thrown and

damage the rakes and tines.
Check the rakes and their tines at regular short

intervals or immediately if there is a noticeable

change in the tool's behavior:

Shut off the engine, hold the machine

securely.

Check the condition and firm seat, watch out

for fine cracks

Replace damaged parts immediately, even if

they have only superficial cracks.

Shut off the engine and remove the spark plug

boot before replacing the tines or rake with

tines – risk of injury!.

Never continue using or attempt to repair dam‐

aged or cracked rakes or tines.

2.8

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.

2.9

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

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, 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

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.
Vibration behavior is influenced by the condition

of the AV elements – check the AV elements at

regular intervals.
