Refueling

-Always stop the engine during refueling, keep away from open flames and do not smoke.

-Always wear protective gloves during refueling. Change and clean protective clothing at regular intervals.

-Be careful not to spill either fuel or oil for environmental protection. Clean the Brush Cutter/String Trimmer imme-

diately if fuel is split.

- Avoid any fuel contact with your clothing. Change your clothing immediately if fuel is split on it to prevent clothing catching fire.

- Inspect the fuel cap regularly to make sure that it is securely fastened and does not leak.

- Always tighten the fuel tank cap securely. Change the location to start the engine (at least 3 meter away from the place of refueling).

-Never refuel in closed rooms. Fuel vapors accumulate, which may cause explosions.

-Only transport and store fuel in approved containers. Make sure the fuel stored is not accessible to children.

Method of operation

-Only use the Brush Cutter/String Trimmer in good light and visibility. During the winter season, always be aware of slippery or wet area, ice and snow. Ensure a safe footing.

-Never cut above waist height.

-Never operate the Brush Cutter/String Trimmer standing on a ladder.

-Never use the Brush Cutter/String Trimmer climbing up into trees.

-Never work on unstable surfaces.

-Remove sand, stones, nails etc. within the working range. Foreign materials may damage the cutting tool and cause dangerous kick-back.

-The cutting tool must have reached full working speed before contact with the grass.

Kickback

-When operating the brush cutter, uncontrollable kickback may occur.

-This is particularly the case when attempting to cut within a blade segment between 12 and 2 o’clock.

-Never use the brush cutter within a segment between 12 and 2 o’clock.

-Never apply the blade of brush cutter to solids, such as bushes and trees, etc., having a diameter in excess of 3 cm or the brush cutter will be deflected at great force with the risk of injuries.

Kickback prevention

To avoid kickback, ensure the following :

-Operation within a blade segment between 12 and 2 o’clock presents positive hazards, especially in using metal cutting tools.

-Cutting operations within a blade segment between 11 and 12 o’clock, and between 2 and 5 o’clock, must only be performed by trained and experienced operators, and then only at their own risk.

Easy cutting with almost no kickback is possible within a blade segment between 8 and 11 o’clock.

Cutting Tools

Use only the correct cutting tool.
