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.
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
Clean any resin and plant reside from the blades using
cleaning agent 531 00 75-13 (UL22) before and after using
the machine.
• Make sure that the blade bolts are well tightened.
• The blade assembly is designed to automatically
compensate for any play between the blades.
Check the cutting edges and reform with a flat file.
Point :
1. Keep the end corner sharp.
2. Round the root of the edge.
3. Do not use water when using a grinder.
• When mounting the blade, make sure to fasten the
spacer, washer and bolt, then fasten the nut.
SHARPENING
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.
