Blade Selection - Echo 99944200418 Instruction Sheet

Blade Selection

Please note if using a blade conversion kit you
MUST use a 20 mm blade. All blade conversion kits
have 20 mm arbors. Blade conversion kit is required
for metal blades.
Not all blades are compatible with all trim-
mers. 8 in. blades are not to be used with a
SRM-3020/T/U and SRM-410X/U. Visit www.
echo-usa.com to find compatible blades.
The type of blade used MUST be matched to
the type and size of material cut. An improp-
er 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 wher-
ever 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.) diam-
eter.
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.
Use Shoulder/Waist Harness
Use of the shoulder/waist harness is recommended
for all trimmer/brushcutter use, not just blade oper-
ation. The shoulder/waist harness when used in a
trimming operation with nylon line head suspends
the trimmer from the operator's shoulder and reduc-
es operator fatigue.
During blade operation, the same fatigue reduction is
achieved. Safety to the operator is also enhanced by
reducing the possibility of blade contact with the oper-
ator's hands and feet by restricting trimmer movement.
Make sure the warning sign on the back of the
shoulder harness can be read easily.
NOTE: In case of emergency, disconnect the trim-
mer/brushcutter from the harness.
