Residual risks
Even if you use this product in accordance with all safety requirements, the potential risk of injury
and damage remains. The following hazards may arise:
- There are harmful health consequences resulting from the emission of vibrations if the product
is used for prolonged periods of time or not managed adequately and properly maintained. The
vibrations can produce the so-called “white finger” disease. If any of the symptoms of "white
finger" syndrome appear, see a doctor immediately. Symptoms of the "white finger" include
numbness, loss of sensitivity, tickling, tingling, pain, loss of strength, colour changes, or skin
condition. These symptoms usually appear on the fingers, hands, or wrists. The risk increases
at low temperatures. To reduce this risk, please wear gloves and keep your hands warm. Limit
the operating time.
- There is a risk of hearing loss during prolonged use if you do not wear hearing protection.
Always wear hearing protection and limit the operating time.
- Cuts if no suitable protective clothing is worn.
-Inhalation of particles and exhaust gases if a mask of protection is not worn.
-Contact with projected objects.
-Burns when touching with hot surfaces.

c. Grass trimmer operation
◼Trimming
Tilt the head slowly to direct debris away from you. If cutting up to a barrier such as fence,
wall or tree, approach from an angle where any debris ricocheting off the barrier will fly away
from you, Move the line head slowly until the grass is cut right up the barrier, but do not jam
(overfeed) the line into the barrier. If trimming up to a wire mesh or chain linked fence be
careful to feed only up to wire. If you go too far the line will snap off around the wire.
Trimming can be done to cut through weed stems one at a time. Place the trimmer line head
near the bottom of the weed-never high up which could cause the weed to chatter and catch
the line. Rather than cut the weed right through, just use the very end of the line to wear
through the stem slowly.
◼Scalping and edging
Both are done with the line head tilted at a steep angle Scalping is removing top growth
without damaging the ground.
Edging is trimming the grass back where it has spread over a sidewalk or driveway. During
both edging and scalping, hold the unit a steep angle and in a position where the debris,
and any dislodging dirt and stones, will not come back towards you even if it ricochets off
the hard surface. Although the picture shows how to edge and scalp every operator must
find for himself the angles which suits his body size and cutting situation.
d. Brushcutter operation
-Do not the brushcutter for cutting trees
-Do not cut with dull, cracked, or damaged blade.
-Before cutting growth, inspect for obstructions such as boulders, metal stakes or strands of wire
from broken fences. If an obstruction cannot be removed, mark its location so that you can
avoid it with the blade. Rocks and metal will dull or damage a blade. Wire can catch on the
blade head and flap around or be thrown into the air.
-Use the shoulder harness always adjust both harness and harness clamp on the unit so that the
unit hangs a few inches above ground level. The cutting head and the debris shield should be
level in all directions. Harness the unit on the right side of your body.
-Cut only with the side of the blade that the debris is moving away from you.
-If kickback occurs, the blade may be dull, or the material so thick and hard that you should use
other tool instead of this machine.
-Do not force the blade to cut. Do not change the angle of cut after into the wood. Avoid using
any pressure or leverage which could cause the blade to bind or crack.
16

◼Scything weeds
This is cutting by swinging the blade in a level arc. It can quickly clear areas of field grass
and weeds. Scything should not be used to cut large, tough weeds or woody growths.
Scything can be done in both directions, and just in one way which results in the debris
being thrown away from you.
That is using the side of the blade that it is rotating away from you. Tilt down the blade
slightly on this same side. You will be hit by some debris if you scythe in both directions.
Cut only with the side of the blade that the debris is moving away from you.
If kickback occurs, the blade may be dull, or the material so thick and hard that you should
use other tool instead of this machine.
Do not force the blade to cut. Do not change the angle of cut after into the wood. Avoid
using any pressure or leverage which could cause the blade to bind or crack.
6. MAINTENANCE & CARE
