GENERAL SAFETY PRECAUTIONS

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.

Adjust the blade setting. This should be 1 mm.

Trimmer head

IMPORTANT!

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

•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.
