SAFETY
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.
For hedge trimmers:
Always check hedges and bushes for foreign objects before trimming.
