The

RON.
In
case

A

will
arise
from

To
obtain
optimum
engine
operation
and
to
protect
your
health
and
the
environment,
only
unleaded
fuel
should
be
used!
For

For
preparing
the
fuel-oil
mixture
first
mix
the
entire
oil
quantity
with
half
of
the
fuel
required,
then
add
the
remaining
fuel.
Thoroughly
Shake
the
mixture
before
filling

trimmer
tank
It
is
not
wise
to
add
more
engine
oil
than
specified
to
ensure
safe
operation.
This
will
only
result
in
a
higher
production
of
combus-
tion
residues
which
will
poliute
the
environment
and
clog
the
exhaust
channel
in
the
cylinder
as
well
as
the
muffler.
In
addition,
the
fuel
consumption
will
rise
and
the
performance
will
decrease.
The engine must be switched off!
