CLEANING
U/SIDE
OF
MOWER
Stop engine and turn fuel tap
"Off".
Disconnect spark
plug lead and wedge the terminal between cylinder head
fins. Ensure throttle control
is
set in
"Stop"
position
to
eliminate fire risk, before attempting
to
clean mower. The
underside
of
your
mower
should be cleaned
to
remove
clogged dirt
or
grass
which
if
allowed
to
build
up
will af-
fect
the
grasscatching performance. It should always be
cleaned immediately after
mowing,
especially
if
an area
has just been dressed
with
sulphate
of
ammonia
or
fer-
tiliser,
to
prevent baseplate corrosion.
A hose may
be
used on
the
underside
of
your
mower
only and special care
must
be taken NOT
to
get
water
in-
to
the engine area
of
your mower,
as
damage may be
done to
the
magneto,
or
water
could get
into
the fuel
system.
If
it
is cleaned regularly
the
baseplate remains
easy
to
clean, because
the
dirt and grass does
not
get
a
chance
to
clog.
NOTE:
When
mowing
in
dusty
conditions ensure
the area
is
lightly watered beforehand
to
eliminate dust.
