SAFETY INSTRUCTIONS
•Regularly check that the muffler is securely attached to the machine.
•The muffler on your machine is equipped with a spark arrestor mesh, this should be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage.
Never use a muffler with a defective spark arrestor mesh.
Cutting equipment
•Only use cutting attachments with the guards we recommend! See the chapter on Technical data.
•Check the cutting attachment for damage or cracks. A damaged cutting attachment should always be replaced.
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
•Tighten the nut using the socket spanner.
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 as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.
Cutting equipment
IMPORTANT!
This section describes how to choose and maintain your cutting equipment in order to:
Reduce the risk of blade thrust.
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.
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! Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise the machine will generate harmful vibration.
