Method of operation
«Only use the brush cutter or grass trimmer in good light and
visibility. During the winter season beware of slippery or wet areas,
ice and snow (risk of slipping). Always ensure a safe footing.
e Never cut above shoulder height.
e Never stand on a ladder and run the brush cutter or grass timmer.
* Never climb up into trees to perform cutting operation with the
brush cutter or grass trimmer.
e Never work on unstable surfaces.
e Remove sand, stones, nails etc. found within the working range.
Foreign particles may damage the cutting tool and can cause
dangerous kickbacks.
e Before commencing cutting, the cutting tool must have reached
full working speed.
elf 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.
e 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)
e When operating the brush cutter, uncontrolled kickback may occur.
e This is particularly the case when attempting to cut within a blade
segment between 12 and 2 o'clock.
e Never apply this segment of the brush cutter to solids, such as
bushes and trees, etc., having a diameter in excess of 3 cm.
e The brush cutter will then be deflected at great force with the
attendent risk of injuries.
e Never apply the brush cutter within a segment between 12 and
2 o'clock.
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.
e Cutting operations within a blade segment between 11 and 12
o'clock, and between 2 and 5 o'ctock, must only be performed by
trained and experienced operators, and then only at their own risk.
e Easy cutting with almost no kickback is possible within a blade
segment between 8 and 11 o'clock.
Cuitting Tools
Employ only the correct cutting tool for the job in hand.
Nylon cutting head:
Exclusively designed for cutting along wall, fences, grass edges,
trees, posts etc. (supplementing the grass mower).
Star blade:
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).
Never use other blades including metal multi-piece pivoting chains
and flail blades. Otherwise serious injury may result.
NOTE:
For RST250, swing the machine from left to right to perform this
cutting work.
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.
e 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.
eTurn off the engine and remove spark plug connector when
replacing or sharpening cutting tools, and also when cleaning the
cutter or cutting tool.
