Blade Selection
The type of blade used MUST be matched to the type and size of 
material cut. An improper or dull blade can cause serious 
personal injury. Blades MUST be sharp. Dull blades increase the 
chance of kick-out and injury to yourself and bystanders.  Never 
use an edging blade, circular saw blade, or any other type of 
unapproved blade.
3-Tooth Grass/Weed Blades may be used wherever the nylon line head is 
used. DO NOT use this blade for heavy weeds or brush.
8 Tooth Weed/Grass Blade is designed for grass, garden debris and thick 
weeds up to 19 mm (0.75 in.) diameter. DO NOT use this blade for brush or 
heavy woody growth.
80 Tooth Brush Blade is designed for cutting brush and woody growth up 
to 13 mm (0.5 in.) diameter.
22 Tooth Clearing Blade is designed for dense thickets and saplings up to 
64 mm (2.5 in.) diameter.
A trimmer-brushcutter with a metal blade can cause serious 
injuries if handled improperly.
Always use extreme care when 
carrying or handling the equipment 
to avoid contact with the cutting 
edges of the blade. Use the optional 
blade cover when unit is not in use.
Keep blades in protective packaging 
until ready to install. Store blades 
safely after removal to prevent injury 
from accidental contact. 
Use blade protectors to protect 
blade teeth during unit 
transportation.
