Overload Cutout; Lubricating The Gearbox - Stihl HLE 71 Instruction Manuals

Overload Cutout

The machine is equipped with an
overload cutout.
The overload cutout disconnects the
power supply in the event of mechanical
overload, e. g., due to
Excessive feed effort
–
"Killing" of the motor speed
–
Pinching of the trimmer blades in
–
the cut
If the overload cutout has disconnected
the power:
Remove the trimmer blades from
N
the cut
Wait for approx. 3 minutes until the
N
overload cutout has cooled down
Do not switch on the machine during this
time, because this substantially extends
the cooling down period.
Once the machine starts again:
Let the machine run for approx.
N
15 seconds without load – this cools
the windings of the motor and
substantially delays renewed
triggering of the overload cutout
