Operation With Blades

Metal blades are very sharp and can cause severe injuries, even 
if engine is off and blades are not moving. Avoid contact with 
blades. Wear gloves to protect hands.

Blade use demands specific brush cutter configuration. 
Operation without specified shield, barrier bar or U-handle, and 
harness can result in serious personal injury. Follow installation 
instructions.

*ANSI standards require brush cutters be equipped with a barrier bar or 
restrictive harness. U-Handle ensures a higher safety factor.

Do Not install blades on GT (Curved Shaft) model trimmers.

• Arbor diameter of upper blade plate must match arbor diameter of blades. 

• A new cotter pin is required each time a blade is installed. 

• Brushcutters over 7.5 kg (16.5 lbs.) dry weight (without fuel) require a 

double shoulder harness.
