Blade Selection - Echo SRM-225 Operator's Manual

SRM-225 OPERATION
Note: The Barrier Bar is used to restrict rearward movement of the unit. The Barrier Bar is NOT A HANDLE and
should not be gripped when using or carrying the unit.

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.
Plastic/Nylon Grass/Weed Blades may be used where 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 (3/4 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 (1/2 in.) diameter.
22 Tooth Clearing Blade is designed for dense thickets and
saplings up to 64 mm (2-1/2 in.) diameter.
Use Shoulder/Waist Harness Use of the Shoulder/Waist
Harness is recommended for ALL Trimmer/Brush Cutter use,
not just Blade operation. The Shoulder/Waist Harness when
used in a trimming operation with nylon line head suspends the
trimmer from the operator's shoulder and reduces operator
fatigue.
