wind line onto spool until
about 13 cm (5 in.) of each

Sharpening Metal Blades

Three styles of metal blades are
approved for use on the ECHO Brush
Cutter. The 8-tooth blade can be
sharpened during normal maintenance.
The clearing blade and 80 tooth blade
require professional service.
Before sharpening, CLOSELY inspect
blade for cracks (look at the bottom of
each tooth and the center mounting hole
closely), missing teeth and bending. If
ANY of these problems are discovered,
replace the blade.
When sharpening a blade, always remove the same amount of materials from
each tooth to maintain balance. A blade that is not balanced will cause unsafe
handling due to vibration and can result in blade failure.
