IMPORTANT
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.

WARNING
• Make sure that the engine has stopped and is cool
before performing any service to the machine. Con-
tact with moving cutting head or hot muffler may
result in a personal injury.
BLADE
• Check the blade and the fasteners for looseness,
cracking, or bending.
• 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.
• You need not to adjust the gap between upper blade
and lower blade as this product is designed to have
optimal gap when it is properly set up.
