X7732278302

Hold trimmer head while turning

knob clockwise to wind line

onto spool until about 13 cm

(5 in.) of each line remains

exposed.

Trimmer head is now fully loaded

and ready for operation.

When the wear indicators
located at the bottom of the
Speed-Feed® head are worn
smooth, or if holes appear,
replacement of the cover or the
entire Speed-Feed® head is
required.

Sharpening Metal Blades

Several styles of metal blades are

approved for use on the

Brushcutter. 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.
