Kickback
– When operating the Petrol Brushcutter, uncontrolled kickback may occur.
– This is particularly the case when attempting to cut within a blade segment
between 12 and 2 o’clock.
– Never apply the Petrol Brushcutter within a segment between 12 and 2
o’clock.
– Never apply this segment of the Petrol Brushcutter blade to solids, such as
bushes and trees, etc., having a diameter in excess of 3 cm or the Petrol
Brushcutter will be deflected at great force with the risk of injuries.
Kickback prevention
To avoid kickbacks, observe the following:
– Operation within a blade segment between 12 and 2 o’clock presents positive
hazards, especially when using metal cutting tools.
– Cutting operations within a blade segment between 11 and 12 o’clock, and
between 2 and 5 o’clock, must only be performed by trained and experienced
operators, and then only at their own risk.
Easy cutting with almost no kickback is possible within a blade segment
between 8 and 11 o’clock.
Maintenance instructions
– The condition of the cutter, in particular of the cutting tool of the protective
devices and also of the shoulder strap must be checked before commencing
work. Particular attention is to be paid to the cutting blades which must be
correctly sharpened.
– Turn off the engine and remove spark plug connector when replacing or
sharpening cutting tools, and also when cleaning the cutter or cutting tool.
