Extending the line for spool set
To extend the line press the spool onto the ground whilst the motor is
turning and the line will extend automatically. For most effective grass
trimming, ensure the machine is operation at full speed and then use
slow shallow sweeps of the line, ensuring that you do not overload the
machine by cutting too fast or cutting through heavy terrain.
Cutting with the spool
Make sure that the work area is free of rock, debris, lines and other
foreign objects.
Start the tool before approaching the grass to be cut.
If you need to release the line, please "bump" the spool button of the
trimmer on the ground to feed out line. If too much line is fed out and it
projects beyond the guard edge it is cut by the line cutting blade.
Cut the grass by swinging the tool from right to left and the tool inclined
forwards at an angle of about 30°. Light cuts are better than heavy cuts
as they allow the cut grass to fall away from the spool preventing the
grass from clogging the spool.
Start cutting nearest the mains power source and work away from it to
make it easier to avoid the cable.
High grass should be cut in layers always beginning from the top. Do not
cut damp or wet grass. Do not overload your tool.
Avoid wearing the line out quickly by knocking against hard objects
(stones, walls, fences etc).
Watch out for kickbacks in the events of impact with hard objects.
After finishing the cutting operation, keep the head close to ground level,
release the switch and follow the motor to come to a complete stand
still. Place the tool on the ground, switch off and remove the cable plug
from the main supply.
