damaged, excessively worn of dull
cutting tools immediately. Such tools
may shatter at high speed and cause
serious or fatal injury.
!Warning!
A loose blade may cause the blade to
vibrate, crack, break or come off the
electric edger, which may result in
serious or fatal injury. Make sure that the
blade is properly tightened. Use the
wrench supplied or one of sufficient
length to obtain the proper torque. If the
blade loosens after being properly
tightened, stop work immediately. The
retaining nut may be worn or damaged
and should be replaced. Never use
unauthorized parts to secure the blade.
Failure to use the proper parts may
cause the blade to fly off and seriously
injure the operator or bystanders. If the
blade continues to loosen, see your
STIHL dealer. Do not attach any blade to
a unit without proper installation of all
required parts. Never use an electric
edger with a loose blade.

Your elektro edger is designed to
produce sharp contoured borders
around lawns and flower beds. It will cut
almost all types of grass, weeds and soft
green plants.
Preparations
If the soil is very dry, spray it with water
before you start work: this softens the
soil a little and also reduces the amount
of dust created. Slightly damp green
plants are easier to cut.
: Inspect the work area and clear
away any obstacles (stones, gravel,
glass, etc.) to reduce the risk of
injury from thrown objects.
: Plan the best route for edging, i.e.
starting point, changes in direction,
etc. Always hold and operate your
edger on the right-hand side of the
body.
Adjusting the depth of cut
: Shut off the engine and wait for the
cutting blade to come to a complete
standstill.
: Loosen wingnut (1)
counterclockwise
: Adjust wheel (2):
Upwards
to increase depth of cut (A).
Downwards
to reduce depth of cut (A).

241BA002 KN
Adjust correctly
The depth of cut varies, depending
on unevenness of the ground, your
height and the way you hold the
edger.
: Use the following procedure:
Adjust the wheel (2) so that the
cutting blade (3) just touches the
ground or breaks the surface of the
soil by no more than 5 mm (0,2“) (B)
in the normal working position.
15EC 70
Page 17
