Cutting Operation
Metal Blade Usage

• Always cut by guiding the head from your right to left.
• A .metal blade cut best up to the point 1/3 from the edge. Use that area for shrubs, tough and thick weeds. For cutting young grass, you can use up to 2/3 from the lip of blade.
• 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.
  (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.

Nylon Cutter Usage

• Nylon cord consumes large power. Please note that the engine rotation speed in operation should be 50% as large as when using metal blade.
• Nylon cutter cuts grass with the power of cord rotation. If you try to cut grass for the length of cord at one time, rotation speed becomes lower due to resistance and you can’t cut well. In ease of large resistance, get the nylon cutter away from grass once, make the rotation speed higher, and cut a small amount of grass at one time.
• If you try to cut grass by swinging the brush cutter in the reverse way(from left to right), scraps fly in the direction away from the body. You can avoid getting your clothes dirty

Fuel Filter
Take the filter out of the fuelling port using a small wire hook. Disconnect the tiller assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with gasoline.

Important
A clogged fuel filler may cause poor acceleration or the engine.

Spark Plug
Remove and inspect the spark plug and clean the electrodes as necessary with Brush.
The spark plug gap should be adjusted to 0.6-0. 7mm. (F15)

Gear Case
Supply multi-purpose grease at every 25 hours of use. Remove the cutter holders to arrange for old grease to exit. (F16)
