BLADE THRUST
Take great care using the blade with the device. Thrust is a reaction that occurs when
the blade hits objects that it can not cut. This can make the blade stop and “push away”
the tool from the object that was unable to be cut. This reaction can be intense enough
to lose control about the object, this process can occur without a warning, as soon as the
blade hits an obstacle and stands still. It will occur in areas, where you cannot see
exactly what you are cutting. This is why you always should cut from right to left to

minimize the reactions.
When transport, this unit must be handled carefully. Do not
expose yourself or others to danger.
● Envelop the blade before storage. Keep children away from it.
● Never remove the machine’s guard.
● Do not store in a closed area where fuel vapors can reach an open
flame from hot water heaters, furnaces, etc. Store in a locked, well ventilated area only.
● Never place the machine in any places where there are flammable materials (dry
grass, etc.), combustible gasses or combustible liquids.
● When the machine is placed in storage for a long time, drain fuel from the fuel tank
and carburetor, clean the parts, move the machine to a safe place and confirm that the
engine is cooled down.
●WARNING: emission of exhaust gases
●WARNING: national regulation can restrict the use of the machine.
Kickback and Related Warnings
● Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad,
brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool to be forced in the direction
opposite of the accessory’s rotation at the point of the binding.
● For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge
of the wheel that is entering into the pinch point can dig into the surface of the material
causing the wheel to climb out or kick out. The wheel may either jump toward or away
from the operator, depending on direction of the wheel’s movement at the point of
pinching.Abrasive wheels may also break under these conditions.
● Kickback is the result of power tool misuse and/or incorrect operating procedures or
conditions and can be avoided bytaking proper precautions as given below.
a) Never place your hand near the rotating accessory. Accessory may kickback over
your hand.
b) Do not position your body in the area where power tool will move if kickback
occurs. Kickback will propel the tool in direction opposite to the wheel’s movement at
the point of snagging.
c) Use special care when working corners, sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the
rotating accessoryand cause loss of control or kickback.
