!Warning!
A worn or damaged muffler is a fire 
hazard and may cause loss of hearing. 
Check to see that the muffler is in good 
condition. The edger must not be 
operated if the muffler is not functioning 
properly or has been removed. 
Remember that the risk of forest fires is 
greater in hot weather. 
Use the spark arresting muffler supplied 
with the unit. Never touch a hot muffler 
or burn will result.
!Warning!
In order to reduce the risk of fire, do not 
modify or remove any part of the muffler 
or spark arrestor.
Tighten all nuts, bolts and screws except 
the carburetor adjustment screws after 
each use.
Keep spark plug and wire connection 
tight and clean. The spark plug electrode 
gap should be checked with a feeler 
gauge at least every 50 operating hours 
and reset if necessary. Fit a new spark 
plug if the electrodes are badly pitted.
Additionally, the daily maintenance 
schedule for your edger set forth in your 
STIHL Owner's Manual should be 
strictly followed.
For any maintenance please refer to the 
maintenance chart and to the warranty 
statement near the end of this manual. 
Store edger indoors in a dry, high or 
locked location out of reach of children.
Before storing for longer than a few 
days, always empty the fuel tank.
Never store the machine with fuel in the 
fuel tank inside a building where fumes 
may reach an open flame or sparks, or in 
a confined area such as a car trunk.
Your power 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.
