CUTTING OPERATION

WARNING

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.

Keep the debris guard attached in place at all times when the unit is operated.

BLADE USAGE (OP7)

1.Always cut by guiding the head from your right to left.

2.A metal blade cut best up to the point 1/3 from the edge. Use that area for cutting shrubs, tough and thick weeds. For cutting young grass, you can use up to 2/3 from the tip of blade.

3.Adjust the engine speed according to the cutting objects. Cut the young grass at middle speed, and cut shrubs or tough and thick weeds at high speed.

OP7

(1) For branches and trees

(2) For grass and weeds

(3) Direction of cutting

(4) Direction of rotation

IMPORTANT

Operating at low speed makes it easier for grass, weeds, or twigs to become caught up in the blades, and also it makes the shaft and clutch wear down more quickly.

WARNING

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

When using this machine, read and obey the precautions and instructions described in “Safety precautions” (pages 5 to 8) of this manual.

Before shouldering the main body of the brushcutter, return the throttle lever to the idling position and make sure the blade has stopped rotating.

When shouldering the main body of the brushcutter, 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.

WARNING

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.

LINE HEAD USAGE

Always remember that the TIP of the line does cutting. You will achieve better results by not crowding the line into the cutting area. Allow the unit to trim at its own pace.

1.Hold the unit so the head is off the ground and is tilted about 20 degrees toward the sweep direction.

2.Use full throttle when cutting.

3.You can avoid thrown debris by sweeping from your left to the right.
