SAFETY INSTRUCTIONS
Cutting equipment
Filing the saw blade
• 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.
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.
• 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.
!
WARNING! Using an incorrect cutting
attachment or an incorrectly sharpened
blade increases the risk of kickback.
IMPORTANT!
Always ensure the trimmer cord is wound tightly and evenly
around the drum, otherwise the machine will generate
harmful vibration.
!
WARNING! Always stop the engine before
doing any work on the cutting attachment.
This continues to rotate even after the
throttle has been released. Ensure that the
cutting attachment has stopped completely
and disconnect the HT lead from the spark
plug before you start to work on it.
