GENERAL SAFETY PRECAUTIONS
Cutting equipment
Saw blades are intended for cutting fibrous types of wood.
Grass blades and grass cutters are intended for cutting 
coarse grass.
A trimmer head is intended for trimming grass.
General rules
Only use cutting attachments with the guards we 
recommend! See the chapter on Technical data.
Keep the teeth of the blade correctly sharpened! Follow our 
instructions and use the recommended file gauge. An 
incorrectly sharpened or damaged blade increases the risk of 
accidents.
Keep the correct setting on the saw blade! Follow our 
instructions and use the recommended setting tool. An 
incorrectly set saw blade increases the risk of jamming and 
kickback, and damage to the saw blade.
Check the cutting attachment for damage or cracks. A 
damaged cutting attachment should always be replaced.
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.
Sharpening the saw blade
See the cutting attachment packaging for correct 
sharpening instructions.
A correctly sharpened blade is essential for working efficiently 
and to avoid unnecessary wear to the blade and clearing saw.
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.
!
WARNING! Always discard a blade that is 
bent, twisted, cracked, broken or damaged 
in any other way. Never attempt to straighten 
a twisted blade so that it can be reused. Only 
use original blades of the specified type.
