Muffler
WARNING! Inspect periodically the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the
machine and have it repaired immediately. Failure to do so may cause the engine to catch fire.
Spark arrester (Fig. 12)
The muffler is equipped with a spark arrester (1) to prevent red hot carbon from flying out of the exhaust outlet. Periodically inspect and clean as necessary
with a wire brush.
Intake air cooling vent (Fig. 13)
Clean the cylinder fins with compressed air or a brush.
(1) Cylinder
(2) Intake air cooling vent
WARNING! Never touch the cylinder, muffler, or spark plugs with your bare hands immediately after stopping the engine. The engine can become
very hot when in operation, and doing so could result in severe burns.
If debris gets stuck and forms a blockage around the intake air vent or between the cylinder fins, it can cause the engine to overheat, resulting
in mechanical failure of the hedge trimmer.
Blades (Fig. 14)
Oil blades after each gas tank filling.
The blade assembly is designed to automatically compensate for any play between the blades.
WARNING! Make sure that the blade bolts are well tightened.
Sharpening (Fig. 15)
Always hold the file or sharpener at a 45° angle to the blade. Always sharpen in the direction of the cutting edge.
Note:
• Files cut only in one direction. Lift the file from the blade when returning to start a new pass.
• Use a grindstone to remove any burr from the edge of the blade.
• Remove as little material as possible.
• Before refitting the sharpened blades, remove filings and then apply grease.
• Do not try to sharpen a damaged blade, change it or take it to an authorised service center.
