– Only transport and store fuel in approved containers. Make sure stored fuel is
not accessible to children.
Method of operation
– Only use the brush cutter/string trimmer in good light and visibility. During the
winter season, beware of slippery or wet areas such as icy or snow-covered
areas (risk of slipping). Always ensure you are on safe footing.
– Never cut above waist height.
– Never stand on a ladder while using the brush cutter/string trimmer.
– Never climb up into trees to use with the brush cutter/string trimmer.
– Never work on unstable surfaces.
– Remove sand, stones, nails etc. found within the working range.
Foreign objects may damage the cutting tool and can cause dangerous kick-
backs.
– Before starting to cut, make sure the cutting tool has reached full working
speed.
– If grass or branches get caught between the cutting tool and guard, always
stop the engine before cleaning. Otherwise unintentional blade rotation may
cause serious injury.
– Take a rest to prevent loss of control caused by fatigue. We recommend to
take a 10 to 20-minute rest every hour.
Kickback (blade thrust)
– When operating the brush cutter, uncontrolled kickbacks may occur.
– Kickbacks occur frequently when attempting to cut with the 12 to 2 o’clock
section of the blade.
– Never apply the 12 to 2 o’clock section of the brush cutter blade.
– Never apply this section of the brush cutter blade to solid objects, such as
bushes or trees etc. that have a diameter greater than 3 cm. Doing so will
cause the brush cutter to deflect with a large amount of force, which is
extremely dangerous and may cause injury.
Kickback prevention
To avoid kickbacks, remember the following:
– Using the 12 to 2 o’clock section of the blade is extremely hazardous,
especially when using metal cutting tools.
– Cutting operations using the 11 to 12 o’clock section and 2 to 5 o’clock section
of the blade must only be performed by trained and experienced operators,
and then only at their own risk.
The optimum cutting section for easy cutting with almost no kickback is
between the 8 to 11 o’clock section of the blade.
Cutting Tools
– Use an applicable cutting tool for the job in hand.
Nylon cutting heads (string trimmer heads) are suitable for trimming lawn
grass.
Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs,
underwood, thicket, and the like.
Never use other blades including metal multi-piece pivoting chains and flail
blades. Otherwise serious injury may result.
– When using metal blades, avoid “kickback” and always prepare for an
accidental kickback. See the section “Kickback” and “Kickback prevention”.
Maintenance instructions
– Have your equipment serviced by our authorized service center, always using
only genuine replacement parts. Incorrect repair and poor maintenance can
shorten the life of the equipment and increase the risk of accidents.
– Always check the condition of the cutter, in particular the cutter protective
devices and shoulder strap, before commencing work. Particular attention
should also be paid to the cutting blades, which must be correctly sharpened.
– Turn off the engine and remove the spark plug connector when replacing or
sharpening cutting tools, and also when cleaning the cutter or cutting tool.
