Method of operation
– Only use the brush cutter in good lighting and visibility. During the winter
season beware of slippery or wet areas, ice and snow (risk of slipping).
Always ensure a safe looting.
– Never cut above the shoulder height.
– Never stand on a ladder and run the brush cutter.
– Never climb up trees to perform cutting operation with the brush cutter.
– Never work on unstable surfaces.
– Remove sand, stones, nails etc. found within the working range.
Foreign particles may damage the cutting tool and can cause dangerous
kick-backs.
– Before commencing cutting, the cutting tool must have reached full working
speed.
Kickback
– 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 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.
Cutting Tools
Employ only the correct cutting tool for the job in hand.
Nylon cutting head:
Exclusively designed for cutting along walls, fences, grass edges, trees, posts
etc. (supplementing the grass mower). Perform this cutting work by swinging
the grass trimmer evenly in half-circles from left to right.
Cutter blade (Star Blade (4 teeth), Eddy Blade (8 teeth), Brush Blade (3
teeth)):
For cutting thick materials, such as weed, high grass, bushes, shrubs,
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
using a scythe).
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.
