Note: Make sure that you can not turn the locknut by
hand. Replace the nut if the nylon lining does not have a
resistance of a minimum of 1.5 Nm. The locknut must be
replaced after it has been put on approximately 10
times.
Cutting equipment
Choose and maintain the cutting equipment to:
• Obtain maximum cutting performance.
• Increase life span of the cutting equipment.
• Follow the checking, maintenance and service
instructions for the muffler.
• Always use the recommended guard for the cutting
equipment. See Technical data.
WARNING: 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 trimmer
line and the correct trimmer line diameter.
WARNING: A faulty cutting attachment may
increase the risk of accidents.
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 spark plug cap before
you start to work on it.

• Only use recommended trimmer heads and trimmer
lines.
• Only use recommended cutting attachments.
• Smaller machines requires small trimmer heads and
vice versa.
• The length of the trimmer line is important. A longer
trimmer line requires greater engine power than a
shorter trimmer line of the same diameter.
• Make sure that the cutter on the trimmer guard is
intact. This cuts the trimmer line to the correct
length.
• Soak the trimmer line in water for a couple of days
before use to increase the life length.
Grass blades and grass cutters
• Use the product with an approved grass blade. Do
not use a grass blade without proper installation of
all required parts. Make sure that the installation is
done correctly and that the proper parts are used.
Improper installation may cause the blade to fly off
and seriously injure the operator or the bystanders.
• Wear protective gloves when you handle or do
maintenance on the blade.
• Use head protection when you operate a product
with a grass blade.
• Grass blades and grass cutters are used to cut
rough grass.
• A grass blade can cause injury while it continues to
spin after the engine is stopped or the throttle trigger
is released. Make sure that the grass blade has
completely stopped rotating before any
maintenance.
• Stop the engine before you do work on the cutting
attachment. Make sure the cutting attachment fully
stops. Disconnect the lead from the spark plug.
• Only use an approved cutting attachment or a
correctly sharpened blade.
• Keep the teeth of the blade correctly sharpened.
• Do not use a damaged cutting attachment.
• Attach the transport guard to the grass blade when
you transport or store the product.
Blade thrust
• A blade thrust is a sudden movement of the product
to the side, forward or rearward. A blade thrust
occurs when the grass blade hits an object that
cannot be cut. In areas where it is not easy to see
the material being cut the risk of blade thrust
increases.
• When a blade thrust occurs, there is a risk that the
product or the operator moves out of position. A
blade that moves can hit bystanders and there is a
risk of injuries.
• If a blade is bent, has cracks, is broken or damaged,
discard the blade.
• Use a sharp blade. The risk of blade thrust increases
when a blade is not sharp.
