N Use a sharpening file (special
accessory) to sharpen dull cutting
attachments. In case of more
serious wear or nicks: Resharpen
with a grinder or have the work done
by a dealer – STIHL recommends a
STIHL servicing dealer.
N Resharpen frequently, take away as
little material as possible: two or
three strokes of the file are usually
enough.
N Resharpen the cutters (1) uniformly
– do not alter the contour or the
parent blade (2) in any way.
See cutting attachment packaging for
additional sharpening instructions.
Balancing
N After resharpening about 5 times,
check the cutting attachment for
out-of-balance on a STIHL balancer
(special accessory) or have it
checked by a dealer and re-
balanced as necessary – STIHL
recommends a STIHL servicing
dealer.
Always check the mowing head for signs
of wear before replacing the nylon line.
If there are signs of serious wear,
replace the complete mowing head.
The nylon mowing line is referred to as
"nylon line" or "line" in the following.
The mowing head is supplied with
illustrated instructions for replacing the
nylon line. You should therefore keep
the instructions for the mowing head in a
safe place.
Adjustment of the nylon line is described
below.
Preparing the machine for replacing
nylon line
N Shut off the engine.
To reduce the risk of injury, always shut
off the engine before replacing nylon
line.
N Put the power tool on the ground
with the mowing head facing up.
N If necessary, remove the mowing
head.
Adjusting Nylon Line
AutoCut mowing head
N With the engine running, hold the
rotating mowing head above the
grass surface.
N Tap it on the ground once – fresh
line is advanced and the blade on
the deflector trims it to the right
length.
Fresh line is advanced every time the
mowing head is tapped on the ground.
For this reason observe the mowing
head's cutting performance during
operation. If the mowing head is tapped
on the ground too often, the line limiter
blade will unnecessarily cut off unused
lengths of nylon line.
Line feed operates only if both lines are
still at least 2.5 cm (1 in) long.
TrimCut mowing head
N Shut off the engine.
To reduce the risk of injury, always shut
off the engine before adjusting the nylon
line by hand.
N Pull the spool up – rotate it about 1/6
turn counterclockwise until it
engages – and allow it to spring
back.
N Pull ends of the lines outward.
Repeat the above procedure as
necessary until both lines are about 13
cm (5 in) long.
Rotating the spool from one stop to the
next advances about 4 cm (1 1/2 in) of
fresh line.
