SAFETY INSTRUCTIONS
5. Muffler
� Never use a machine that has a defective muffler. � Check regularly that the muffler is secure. � If your muffler is fitted with a spark arrest screen then it should be cleaned regularly. A blocked screen leads to the engine overheating with serious damage as a result. Never use a muffler with a defective spark arrest screen.
7. Blade guard
� Check that the blade guard is not damaged or distorted. � Replace the blade guard if it is bent or damaged.
6. Blades
The contact pressure between the blades is adjusted automatically by the wave-formed plate (A). The four screws with nuts (B) should be tightened (20 Nm) without regard to the contact pressure. The edges of the blade are too hard to be filed. Dull blades should be sharpened using a grinder.
