Stihl FS 40 Manual De Instrucciones página 13

Warning!
This trimmer is normally to be used at
ground level with the cutting attachment
parallel to the ground. Use of a trimmer
above ground level or with the cutting
attachment perpendicular to the ground
may increase the risk of injury, since the
cutting attachment is more fully exposed
and the power tool may be more difficult
to control.
Warning!
During cutting, check the tightness and
the condition of the cutting attachment
at regular short intervals with the engine
and attachment stopped. If the behavior
of the attachment changes during use,
stop the engine immediately, wait until
the cutting attachment stops, and check
the nut securing the attachment for
tightness and the head for cracks, wear
and damage.
Warning!
A loose head may vibrate, crack, break
or come off the trimmer, which may
result in serious or fatal injury. Make
sure that the cutting attachment is prop-
erly tightened. Use the wrench supplied
or one of sufficient length to obtain the
proper torque. If the head loosens after
being properly tightened, stop work
immediately. The retaining nut may be
worn or damaged and should be
replaced. If the blade or head continues
to loosen, see your STIHL dealer. Never
use a trimmer with a loose cutting
attachment.

Warning!
Replace a cracked, damaged or worn-
out head or a cracked, bent, warped,
damaged, dull or worn out blade imme-
diately, even if damage is limited to
superficial cracks. Such attachments
may shatter at high speed and cause
serious or fatal injury.
Warning!
If the head, blade or deflector becomes
clogged or stuck, always shut off the
engine and make sure the cutting
attachment has stopped before clean-
ing. Grass, weeds, etc. should be
cleaned off the blade or from around the
head at regular intervals.
Warning!
To reduce the risk of unintentional rota-
tion of the cutting attachment and injury,
always shut off the engine and remove
the spark plug boot before replacing the
cutting attachment. To reduce the risk of
injury, always shut off the engine before
adjusting the length of the nylon line on
manually adjustable mowing heads.
Warning!
The gearbox becomes hot during oper-
ation. To reduce the risk of burn injury,
do not touch the gear housing when it is
hot.
Warning!
Never modify your muffler. Any modifi-
cation could cause an increase in heat
radiation, sparks or sound level, thereby
increasing the risk of fire, burn injury or
hearing loss. You may also permanently
damage the engine. Have your muffler
serviced and repaired by your STIHL
servicing dealer only.
Warning!
The muffler and other parts of the
engine (e.g. fins of the cylinder, spark
plug) become hot during operation and
remain hot for a while after stopping the
engine. To reduce risk of burns, do not
touch the muffler and other parts while
they are hot. Keep the area around the
muffler clean. Remove excess lubricant
and all debris such as pine needles,
branches or leaves. Let the engine cool
down sitting on concrete, metal, bare
ground or solid wood (away from any
combustible substances.
Warning!
An improperly mounted or damaged cyl-
inder housing or a damaged/deformed
muffler shell may interfere with the cool-
ing process of the muffler. To reduce the
risk of fire or burn injury, do not continue
work with a damaged or improperly
mounted cylinder housing or a dam-
aged/deformed muffler shell.
Your muffler is furnished with a spark
arresting screen designed to reduce the
risk of fire from the emission of hot
particles. Never operate your unit with a
missing or damaged spark arresting
screen. If your gas/oil mix ratio is correct
