in order to operate
the
edger.
Releasing
the blade

edger
blade.
Primer
8lade DepthControl Lever
The primer
is used to pump
gas into the carburetor
and aid in
starting
the engine.
Use it to start a cold engine,
but do not use it
to restart
a warm
engine
after
a short
shutdown.
The blade
depth
control
lever
is located
on the right
side of
the upper
handle.
It is used to control
the depth
of the cut. The
further
forward
the blade
depth
control
lever is moved,
the
deeper
into the soil the edger
blade
will cut.
Starting the Engine
To start the edger's
engine,
proceed
as follows:
1.
Attach
the spark
plug
wire to the spark
plug.
Make certain
the metal
cap on the end of the spark plug
wire is fastened
securely
over the
metal
tip on the spark
plug.
2.
Move
the blade
depth
control
lever back to the START
position
in the adjacent
(top) notch.
3.
Depress
the primer
bulb
three
times,
pausing
two
to three
seconds
between
each
push. In cold weather
(below
50°F
/19°C), it may be necessary
to depress
the primer
bulb
four
or five times.
NOTE: Using the primer
to restart
a warm
engine
after
a
short
shutdown
is usually
not necessary.
Doing
so may
result
in a flooded
engine.
4.
Standing
behind
the edger,
depress
the blade
control
and
hold
it against
the upper
handle
with your
left hand.
i_i
WARNING!
This control
mechanism
is a safety
device.
