Angle drive
Lubricate the angle drive with STIHL
gear lubricant for brushcutters – see
"Special Accessories".
N
Check the lubricant level at regular
intervals of about every 25 hours of
operation. Unscrew the filler
plug (2) – if no grease can be seen
on the inside of the filler plug, screw
the tube of grease into the filler hole.
N
Squeeze up to 1/5 oz (5 g) grease
into the gearbox.
NOTICE
Do not completely fill the gearbox with
grease.
N
Unscrew the tube of grease from the
filler hole.
N
Refit the filler plug and tighten it
down firmly.
When cutting performance and behavior
begin to deteriorate, i.e. blades
frequently snag on branches:
Resharpen the cutting blades.
It is best to have the cutting blades
resharpened by a dealer on a workshop
sharpener. STIHL recommends a STIHL
servicing dealer.
It is also possible to use a flat crosscut
sharpening file. Hold the sharpening file
at the prescribed angle (see
"Specifications").
N
Only sharpen the cutting edge – do
not file blunt projecting parts of the
cutting blade or the cutting blade
guard (see "Main Parts and
Controls")
N
Always file towards the cutting
edge.
N
The file only sharpens on the
forward stroke – lift it off the blade
on the backstroke.
N
Use a whetstone to remove burr
from cutting edge.
N
Remove as little material as
possible.
N
After sharpening, clean away filing
or grinding dust and then spray the
cutting blades with STIHL resin
solvent.
NOTICE
Do not operate your machine with dull or
damaged cutting blades. This may
cause overload and will give
unsatisfactory cutting results.
For periods of 3 months or longer
N
Drain and clean the fuel tank in a
well ventilated area.
N
Dispose of fuel properly in
accordance with local
environmental requirements.
N
Run the engine until the carburetor
is dry – this helps prevent the
carburetor diaphragms sticking
together.
N
Clean the cutting blades, check
condition and spray with STIHL
resin solvent.
N
Fit the blade scabbard.
N
Thoroughly clean the machine – pay
special attention to the cylinder fins
and air filter.
