English
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.
■ INTAKE AIR COOLING VENT
• 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. (MA4)
• If waste gets stuck and causes blockage around the
intake air cooling vent or between 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
Oil blades each gas tank filling (MA5).
• Make sure that the blade bolts are well tightened.
• The blade assembly is designed to automatically
compensate for any play between the blades.
■ Sharpening (MA6)
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 all burr from the edge of the blade with a
slip stone;
• 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 a Service dealer.
