Locking nut
• When fitting, tighten the nut in the opposite direction to the
direction of rotation of the cutting attachment. To remove
it, undo the nut in the same direction as the cutting
attachment rotates. (CAUTION! The nut has a left-hand
thread.)
• Tighten the nut using the socket spanner. 35-50 Nm (3.5-
5 kpm).
CAUTION! The nylon lining inside the locking nut must not
be so worn that you can turn it by hand. The lining should
offer a resistance of at least 1.5 Nm. The nut should be
replaced after it has been put on approx. 10 times.
WARNING! Never use a machine with faulty

safety equipment. The machine's safety
equipment must be checked and maintained

SAFETY INSTRUCTIONS
• Make sure that the blade is well supported when you file
it. Use a 5.5 mm round file with a file holder.
The filing angle is 15 ° . File alternate teeth to the right and
•
those in between to the left. If the blade has been heavily
pitted by stones it may be necessary to dress the top
edges of the teeth with a flat file, in exceptional cases. If
so, this should be done before filing with a round file. The
top edges must be filed down by the same amount for all
the teeth.
• Adjust the blade setting. This should be 1 mm.
Sharpening grass cutters and grass
blades
• See the cutting attachment packaging for correct
sharpening instructions.
• Sharpen blades and cutters using a single-cut flat file.
• Sharpen all edges equally to maintain the balance of the
blade.
Trimmer head
• Only use the recommended trimmer heads and trimmer
cords. These have been tested by the manufacturer to suit
a particular engine size. This is especially important when
a fully automatic trimmer head is used. Only use the
recommended cutting attachment. See the chapter on
Technical data.
