first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench. TIGHT-
ENING TORQUE IS: 9.8–13.7 Nm (87–121 in-lbs)!
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. Note that
failing to do so may result in the engine catching on fire.
Spark arrester (MA4)
The muffler is equipped with a spark arrester to prevent red hot carbon from flying
out of the exhaust outlet. Periodically inspect and clean as necessary with a wire
brush. In some countries, it might under certain circumstances be required by law
to equip a spark arrester.
Intake air cooling vent (MA5)
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. Clean the cylinder
fins with compressed air or a brush.
IMPORTANT:
If waste gets stuck and causes blockage around the intake air cooling vent or be-
tween the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical
failure on the part of the hedge-trimmer.
Blades (MA6)
Oil blades each gas tank filling.
WARNING:
Make sure that the blade bolts are well tightened. The blade as-
sembly is designed to automatically compensate for any play between the blades.
Sharpening (MA7)
Always keep the file or sharpener at an angle of 45° to the blade, and always grind
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. Remove every burr from the edge of the blade with a slip stone.
Remove as little material as possible. Before refitting the sharpened blades, re-
move filings and then apply grease. Do not try to sharpen a damaged blade:
change it or take it to a qualified workshop.
