See the cutting attachment packaging for correct 
sharpening instructions. A correctly filed 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.

Adjust the blade setting. This should be 1 mm.

 

•

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.

 

•

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.

•

Smaller machines generally require small trimmer heads 
and vice versa. This is because when clearing using a 
cord the engine must throw out the cord radially from the 
trimmer head and overcome the resistance of the grass 
being cleared.

•

The length of the cord is also important. A longer cord 
requires greater engine power than a shorter cord of the 
same diameter.

•

Make sure that the cutter on the trimmer guard is intact. 
This is used to cut the cord to the correct length.

•

To increase the life of the cord it can be soaked in water 
for a couple of days. This will make the line tougher so that 
it lasts longer.

IMPORTANT!

This section describes how to choose and maintain your 
cutting equipment in order to:

Reduce the risk of kickback.

Obtain maximum cutting performance.

Extend the life of cutting equipment.

Only use cutting attachments with the guards we 
recommend! See the chapter on Technical data.

Refer to the instructions for the cutting attachment to check 
the correct way to load the cord and the correct cord 
diameter.

Keep the teeth of the blade correctly sharpened! Follow our 
recommendations. Also refer to the instructions on the 
blade packaging.

Maintain the correct blade setting! Follow our instructions 
and use the recommended file gauge.

 

IMPORTANT!

Always ensure the trimmer cord is wound tightly and evenly 
around the drum, otherwise the machine will generate 
harmful vibration.
