Working Technique
Vertical Cut
Swing the cutting blade from the bottom
upwards in an arc – lower the nose of the
blade, move along the hedge and then
swing the blade up again in an arc.
Any working position above head height
is tiring. To minimize the risk of
accidents, work in such positions for
short periods only.

Horizontal Cut
Hold the cutter bar at an angle of 0° to
10° as you swing the hedge trimmer
horizontally.
Swing the cutting blade in an arc
towards the outside of the hedge so that
the cuttings are swept to the ground.
Cuttings can be easily swept off the
hedge with the aid of the optional
catcher plate on the cutting blade.

Fuel

This engine is certified to operate on
unleaded gasoline and the STIHL two-
stroke engine oil at a mix ratio of 50:1.
Your engine requires a mixture of high-
quality gasoline and two-stroke air
cooled engine oil.
Use mid-grade unleaded gasoline with a
minimum octane rating of 89 ((R+M)/2)
and no more than 10% ethanol content.
NOTICE
Fuel with an octane rating below 89 may
increase engine temperatures. This, in
turn, increases the risk of piston seizure
and damage to the engine.
The chemical composition of the fuel is
also important. Some fuel additives not
only detrimentally affect elastomers
(carburetor diaphragms, oil seals, fuel
lines, etc.), but magnesium castings and
catalytic converters as well. This could
cause running problems or damage the
engine. For this reason STIHL
recommends that you use only quality
unleaded gasoline!
NOTICE
Gasoline with an ethanol content of
more than 10% can cause running
problems and major damage in engines
and should not be used.

The ethanol content in gasoline affects
engine speed – it may be necessary to
readjust the carburetor if you use fuels
with various ethanol contents.
