the winter season beware of slippery or wet areas, ice and snow (risk of
slipping). Always ensure a safe footing.

– Never stand on a ladder and run the Brush cutter/Grass trimmer.
– Never climb up into trees to perform cutting operation with the Brush cutter/

– When operating the brush cutter, 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 brush cutter within a segment between 12 and 2 o’clock.
– Never apply this segment of the brush cutter blade to solids, such as
bushes and trees, etc., having a diameter in excess of 3 cm or the brush
cutter will be deflected at great force with the risk of injuries.
Kickback prevention
To av oid kick bac k s, obse rve the fo l lowi ng:
– 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 experi-
enced 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.
Cutting Tools
Employ only the correct cutting tool for the job in hand.

underwood, thicket etc. (max. 2 cm dia. thickness). Perform this cutting work
by swinging the brush cutter evenly in half-circles from right to left (similar to

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.
