GENERAL
RECOMMENDATIONS
Always observe safety rules when performing any maintenance.
The warranty on this
trimmer
mower does
not
cover items
that
have
been subjected
to
operator abuse
or
negligence.
To
receive full value
from
the
warranty,
the
operator must maintain
the
trimmer
mower
as
instructed here.
Changing engine-governed speed voids engine warranty.
All adjustments should
be
checked
at
least once each season.
Periodically check
all
fasteners and make sure these are tight.
GENERAL
LUBRICATION
Lightly lubricate
all
moving parts
of
the
machine
at
the
end
of
the
season
or
every
25
operating hours.
