Grass Cutting
– fig 12
Cut the grass ,like if you were in a corridor of 1.5 meters ,wide ,move step by step balancing the
machine right and left,and vice-versa.Make sure at each step that you are still well balance on
your feet .If you are using the 3 teeth blade for the grass ,always cut your right to left and leave a
pile of cut grass on the left for later gathering.
If possible, avoid stones even small ones,piles of earth,small piece of wood or anything that could
be hidden or poorly visible in the grass.If you hit a large object by accident,or if you block the
cutting tool due to overloading ,or overload of grass or stringy vegetal material wrapped in the
cutting tool,you must : reduce the speed to the idle speed and disengage the clutch .Make sure
that the cutting tool is stopped by pushing tile stop button .
Put the brush cutter on the ground and check that the cutting tool has not been damaged such as
breakage of teeth for the blade,cracking.If necessary ,change the cutting tool,If the tool is only
wrapped by vegetal material,with your pair of gloves remove the vegetal materials and clean the
cutting tool.
Brush cutter transmit vibrations to the user during operation. Even the machine is equipped with
an anti-vibrating device,the vibration can generate an increased tiredness.For this reason,we
recommend taking regular pauses during work..We recommend as well that after a few hours of
work,to take a pause (a few minutes) and leave the engine at idle rpm in order to cool down by the
air current created by the flywheel.
Stop the engine
Allow the engine to operate at idle speed.
Position switch (7) on the control handle to "0"
CAUTION: The cutting head stops rotating seconds after stopping the engine;
tight hold both handles up to the completely stop of the cutter.

Change nylon line
Remove the wire guard by rotating the cover.
Remove the coil wire with debris and compression spring
Hold the new coil wire and remove each 10 cm of both threads,
Place the conical spring coil on both threads and go through the eye of the round metal coil
housing
Place the new spool and turn it so that it overlaps the cover ears springs bobbin case.

Cleaning and maintenance
Our machines have been designed to operate over a long period of time with a minimum of
maintenance. Continuous satisfactory operation depends upon proper machine care and regular
cleaning.
