10. Safety devices
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Risk of injury!
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; STIHL recommends STIHL
specialist dealers.
10.1 Safety devices
The lawn mower is equipped with safety
devices, which prevent inadvertent contact
with the mowing blade and with ejected
clippings.
These include the housing, discharge flap,
grass catcher box and correctly installed
handlebar.
10.2 Two-hand operation
The motor can only be switched on by
pressing and holding the ON button with
the right hand and then pulling the
motorstop lever to the handlebar with the
left hand.
10.3 Motor run-down brake
When the motorstop lever is released, the
mowing blade comes to a complete
standstill in less than three seconds.
An integrated motor run-down brake
shortens the run-down time until the blade
stops.

Measuring run-down time
Following motor start-up, the blade rotates
and a wind noise is audible. The run-down
time corresponds to the duration of the
wind noise after the motor stops. This can
be measured using a stopwatch.
11. Operating the machine
11.1 Electrical connection
Danger of electric shock!
Observe the safety instructions in
the section "For your safety"
( 4.8).
If using a cable drum, the
connection cord must be unwound
completely, otherwise electrical
resistance may cause loss of power
and overheating.
Only cables which are no lighter than the
following rubber sheathed cables may be
used as electric cables:
H07 RN-F DIN/VDE 0282
Minimum cross-section:
up to 25 m length: 3 x 1,5 mm²
up to 50 m length: 3 x 2,5 mm²
The connectors of the electric cables must
be made of rubber or have a rubber cover
and conform to the following standard:
DIN/VDE 0620
The mains voltage and mains frequency
must correspond to the information on the
rating plate and the information contained
in the section "Technical specifications"
( 18.).
The power cable must be adequately
protected by fuse ( 18.).
This machine is intended for operation with
a power supply having a system
impedance of Z at the transfer point
max
(house connection) of maximum
0,49 ohms (at 50 Hz).
The user must ensure that the machine is
only operated with a power supply which
meets this requirement. If necessary, this
information can be obtained from the local
electric power company.
11.2 Strain relief
During working, the strain relief
prevents any unintentional
disconnection of the electric cable and any
resulting damage to the mains connection
on the machine.
For this reason, the electric cable must be
fed through the strain relief.
● Form a loop in the power cable (1) and
guide it through the opening (2).
● Then push the loop over the hook (3)
and pull it tight.
11.3 Switching on lawn mower
Do not switch on the lawn mower in
tall grass. Select a higher cutting
height setting if the motor is difficult
to start.
● Press and hold down ON button (1).
Pull motorstop lever (2) to handlebar
and hold.
● The ON button (1) can be released
once motorstop lever (2) is pressed.
