transportation to avoid damage. – When transporting the brush cutter, ensure that the fuel tank is completely empty, to avoid fuel leakage. – If the equipment gets heavy impact or fall, check the condition before continuing work. Check the fuel system for fuel leakage and the controls and safety devices for malfunction. If there is any damage or doubt, ask our authorized service center for the inspection and repair. Refueling

– Avoid skin contact with petroleum products. Do not inhale fuel vapor. Always wear protective gloves during refuelling. Change and clean protective clothing at regular intervals. – Take care not to spill either fuel or oil. Always wipe unit dry before starting engine. Allow wet cloths to dry before disposing in proper, covered container to prevent spontaneous combustion. – Avoid any fuel contact with your clothing. Change your clothing immediately if fuel has spilled on it (danger hazard). – Inspect the fuel cap at regular intervals making sure that stays securely fastened. – Carefully tighten the locking screw of the fuel tank. Change locations to start the engine (at least 10ft. or 3 meters away from the place of refueling). – Never refuel in closed rooms. Fuel vapors accumulate at ground level (risk of explosions). – Only transport and store fuel in approved containers. Make sure stored fuel is not accessible to children. – Do not attempt to refuel a hot or a running engine. – When mixing gasoline with two-stroke engine oil, use only gasoline which contains no ethanol or methanol (types of alcohol). This will help to prevent damage to fuel lines and other engine parts.5 Caution: Kickback Diagrammatic

Method of operation – Use the brush cutter only in good light and visibility. During cold seasons beware of slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe footing. – Do not overreach. Keep proper footing, balance and hand control of the unit at all times. – Never cut above waist level. – Never stand on a ladder while running the brush cutter. – Never climb up into trees to perform any cutting operation with the brush cutter. – Never work on unstable surfaces or steep terrain. – Remove all objects such as stones, nails, broken glass, wire, etc. found within the working ares. Foreign articles may damage the cutting tool, can cause dangerous kickbacks, or could be thrown about dangerously. – Before commencing cutting the cutting tool must have reached full working speed. – Never operate this tool while it is turned upside-down or when it is at an extreme angle. – WARNING! – The cutter area is still dangerous while the machine is coasting to a stop. – If grass or branches get caught between the cutting tool and guard, always stop the engine before cleaning. Otherwise unintentional blade rotation may cause serious injury. – Take a rest to prevent loss of control caused by fatigue. We recommend to take a 10 to 20-minute rest every hour. Kickback (blade thrust) – When operating the brush cutter, uncontrolled kickback can occur. – This particularly is the case when attempting to cut within a blade segment between 12 and 2 o’clock as viewed from the operator’s position. – Never touch this segment of the brush cutter to solid objects, such as bushes, stumps, trees, etc., with a diameter greater than 3 cm.

potential risk of serious injuries. – Never operate the brush cutter using the blade segment between the 12 and 2 o’clock position. Kickback prevention To avoid kickbacks, observe the following: – Operation within the blade segment between 12 and 2 o’clock can cause serious potential hazards, especially when using metal cutting blades. Use of this brush cutter utilizing blade segment positions from 11 to 12 o’clock and 2 to 5 o’clock can still cause a likely potential for some kickback. – Cutting operations attempted within the blade segments between 11 and 12 o’clock, and between 2 and 5 o’clock, should only be performed by trained and experienced operators, and only at their own risk. Smooth and easy cutting with almost no kickback is possible using the blade segment between 8 and 11 o’clock. Cutting Tools
