 CUTTING OPERATION

WARNING

1  Always wear eye protection such as safety 

goggles. Never lean over the rotating cutting head. 
Rocks or other debris could be thrown into eyes 
and face and cause serious personal injury.

2  Keep the debris guard in place at all times when 

the unit is operated.

  CUTTING OPERATION

WARNING

When using a metal blade, do not cut grass with the 
right half of the blade. Otherwise, the machine might 
kick back, causing a serious injury.

(1) Area of the blade where 

the machine is prone to 
kick back

WARNING

•  When using this machine, read and obey the pre-

cautions and instructions described in “For safe 
operation” (pages 5 to 8) of this manual.

•  Before shouldering the main body of the brushcut-

ter, return the throttle lever to the idling position 
and make sure the blade has stopped rotating.

•  When shouldering the main body of the brushcut-

ter, be careful that the throttle wire does not get 
tangled, and that the blade does not touch the 
ground.

WARNING

This product employs a plot type carburetor. If the 
engine is tilted too much, the fuel in the breather or 
carburetor of the fuel tank might leak out. Do not tilt 
the engine upward or downward during cutting, or 

when storing or transporting the brushcutter.

IMPORTANT

Be careful not to hit the blade against any object during 
cutting. Hitting the blade against stones, etc. might 
damage the blade and driving unit, or bend the main 
pipe.

  WHEN USING A METAL BLADE

•  Swing the blade from right to left to cut grass.
•  To cut usual grass, use the part of the blade corre-

sponding to 1/2 of the diameter of the blade. To cut 
tough weeds such as Japanese pampas grass and 
Solidago altisima, use the part of the blade corre-
sponding to 1/3 of the diameter of the blade.

•  Adjust the rotation speed of the engine in accordance 

with the resistance of grass. Cut young grass at 
middle speed, and cut tough and thick grass such 
as Japanese mugwort and vines at high speed.

IMPORTANT

Operating the engine at low speed might cause grass, 
weeds or twigs to be caught up in the blade. It also 
wears down the clutch more quickly.

(1) Usable area of the blade
(2) Area to be used for cutting young grass
(3) Area to be used for cutting tough grass
