Stihl FS 40 Instruction Manual page 6

English
– Use only an approved combination
of cutting attachment, deflector,
handle and harness. All parts must
be assembled properly and
securely. To reduce the risk of
injury, never use metal cutting
attachments.
– The stop switch must move easily to
0.
– Smooth action of choke lever,
throttle trigger interlock and throttle
trigger – the throttle trigger must
return automatically to the idle
position. The choke lever must
spring back from the g and <
positions to the run position F when
the throttle trigger interlock and
throttle trigger are squeezed.
– Check that the spark plug boot is
secure – a loose boot may cause
arcing that could ignite combustible
fumes and cause a fire.
– Cutting attachment Check for
correct and secure assembly and
good condition.
– Check protective devices (e.g.
deflector for cutting attachment) for
damage or wear. Always replace
damaged parts. Never operate the
unit with a damaged deflector.
– Never attempt to modify the controls
or the safety devices in any way.
– Keep the handles dry and clean –
free from oil and dirt – for safe
control of the power tool.
– Adjust the harness and handle(s) to
suit your height and reach.
To reduce the risk of personal injury,
do not operate your machine if it is
damaged or not properly assembled.

If you use a shoulder strap or full
harness: Practise removing and putting
down the machine as you would in an
emergency. To avoid damage, do not
throw the machine to the ground when
practising.
Starting the Engine
Start the engine at least 3 meters from
the fueling spot, outdoors only.
Place the unit on firm ground in an open
area. Make sure you have good balance
and secure footing. Hold the unit
securely. The cutting attachment must
be clear of the ground and all other
obstructions because it may begin to run
when the engine starts.
Your trimmer is a one-person unit. To
reduce the risk of injury from thrown
objects, do not allow other persons
within a radius of 15 meters of your own
position – even when starting.
To reduce the risk of
injury, avoid contact with
the cutting attachment.
Do not drop start the power tool – start
the engine as described in the
instruction manual.
Note that the cutting
attachment continues to
run for a short period
after you let go of the
throttle trigger – fly-
wheel effect.
Check idle speed: The cutting
attachment must not rotate when the
engine is idling with the throttle trigger
released.
To reduce the risk of fire, keep hot
exhaust gases and hot muffler away
from easily combustible materials (e.g.
wood chips, bark, dry grass, fuel).
Holding and Controlling the Unit
Always hold the unit firmly with both
hands on the handles. Make sure you
always have good balance and secure
footing.
Left hand on loop handle, right hand on
control handle, even if you are left-
handed.
During Operation
In the event of impending danger or in
an emergency, switch off the engine
immediately – move the stop switch in
the direction of 0.
