Instruction manual

Congratulations! You have purchased a new MAKITA brushcutter!
We thank you for your trust and hope you will be completely
satised with your new brushcutter.
Brushcutters of the series BCX3400 / 3410 are included among
the lightest brushcutters with a four-stroke engine in this class.
These brushcutters are very handy, compact and multipurpose
and can be used to cut grass, weeds and brushwood.
The considerably lower fuel consumption compared to similar
brushcutters with two-stroke engines is a highly advanced step
in terms of energy consumption and emissions.
Furthermore, the four-stroke engine is an agreeably quiet
engine.
To ensure your personal safety and to guarantee optimum
operation of the brushcutter including readiness to operate,
we kindly ask you to:
Read this instruction manual carefully
before putting the brushcutter into ope-
ration for the first time and to strict-
ly observe the safety instructions!
Nonobservance can result in serious injuries!
Proper use:
These brushcutters are intended to be used with the appropriate
and approved cutting tools for the purpose of cutting grass or
thick weeds. The brushcutter is only allowed to be used by one
person at a time and only outdoors!
Unapproved working technique:
Thicker material such as shrubs, wild plants or thickets is not
allowed to be cut using the approved cutting tools.
Unapproved users:
Persons who are not familiar with the instruction manual, child-
ren, young persons, as well as persons under the inuence of
alcohol, drugs or medication, are not allowed to operate the
machine.
