Refueling

Shut off the engine during refueling, keep away from open ames and do not – smoke.

Avoid skin contact with mineral oil products. Do not inhale fuel vapor. Always – wear protective gloves during refueling. Change and clean protective clothing at regular intervals.

Take care not to spill either fuel or oil in order to prevent soil contamination – (environmental protection). Clean the brushcutter or string trimmer immediately after fuel has been spilt.

Avoid any fuel contact with your clothing. Change your clothing instantly if –

fuel has been spilt on it (to prevent clothing catching re).

Inspect the fuel cap at regular intervals making sure that it can be securely – fastened and does not leak.

Carefully tighten the fuel tank cap. Change location to start the engine (at – least 3 meters away from the place of refueling).

Never refuel in closed rooms. Fuel vapors accumulate at ground lever (risk of – explosions).

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

3 meters

Method of operation

Only use in good light and visibility. During the winter season beware of – slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe footing.

Never cut above waist height. – Never stand on a ladder. – Never climb up into trees to perform cutting operation. – Never work on unstable surfaces. – Remove sand, stones, nails etc. found within the working range. –

Foreign particles may damage the cutting tool and can cause dangerous kick-backs.

Before commencing cutting, the cutting tool must have reached full working – speed.

When using metal blades, swing the tool evenly in half-circle from right to left, – like using a scythe.

Cutting Tools

Use an applicable cutting tool for the job in hand. – Nylon cutting heads (nylon line) are suitable for trimming lawn grass. Metal blades are suitable for cutting weeds, high grasses, bushes, shrubs, underwood, thicket, and the like.

When using metal blades, always use the approved protector, handle (with – barrier bar) and harness for use of metal blades. Otherwise blade contact may cause serious injury. See the section “Approved combination of cutting tool, protector, handle and harness.”

When using metal blades, avoid “kickback” and always prepare for an – accidental kickback. See the section “Kickback” and “Kickback prevention.”

Kickback

When operating the Brushcutter, uncontrolled kickback may occur. – This is particularly the case when attempting to cut within a blade segment –

between 12 and 2 o’clock. Never apply the Brushcutter within a segment between 12 and 2 o’clock. – Never apply this segment of the Brushcutter blade to solids, such as bushes –

and trees, etc., having a diameter in excess of 3 cm or the Brushcutter will be

deected at great force with the risk of injuries.

Kickback prevention

To avoid kickbacks, observe the following:

Operating 12 and 2 o’clock presents a hazard, especially when using metal – blades.

Cutting 11 and 12 o’clock, and between 2 and 5 o’clock, must be performed – by trained and experienced operators, and then only at their own risk. Easy cutting with almost no kickback is possible between 8 and 11 o’clock.

Maintenance instructions

The condition of the cutter, in particular of the cutting tool of the protective – devices and also of the shoulder strap must be checked before commencing work. Particular attention is to be paid to the cutting blades which must be correctly sharpened.

Turn off the engine and remove spark plug connector when replacing or – sharpening cutting tools, and also when cleaning the cutter or cutting tool.

BEFORE START OF OPERATION

Inspectionandrellofengineoil

Perform the following procedure, with the engine cooled down. – Set the engine level, remove oil cap (Fig. 1), and check to see whether or not there is oil in the range between the upper limit and lower limit –

marks of the oil pipe (Fig. 2). Fill with oil to upper limit mark if oil is insufcient (oil level is close to lower limit mark) (Fig. 3). – The area surrounding the external marks is transparent, so the amount of oil inside can be checked without having to remove the oil cap. –

However, if oil pipe becomes extremely dirty, visibility may be lost, and oil level will have to be checked against stepped section on inside of oil pipe.

For reference, the oil rell time is about 10h (10 times or 10 tanks of gas before oil needs to be relled). – If the oil changes in color or mixes with dirt, replace it with new one. (For the interval and method of replacement, refer to P 19)

Recommended oil: SAE 10W-30 oil of API Classication, Class SF or higher (4-stroke engine for automobile) Oil volume: Approx. 0.08L

NOTE: If the engine is not kept upright, oil may pool in other parts of the engine. The oil levelgauge may give an incorrect reading for oil level.

Do not ll with oil if engine is not upright. If the oil is lled above the limit, the oil may be contaminated or may catch re with white

smoke.

Point 1 in Replacement of oil: “Oil cap”

Remove dust or dirt near the oil rell port, and detach the oil cap. – Keep the detached oil cap free of sand or dust. Otherwise, any sand or dust adhering to the oil cap may cause irregular oil circulation or –

wear on the engine parts, which will result in troubles.

Oil

The area between the external upper and lower limits is transparent, so oil level can be checked externally against these marks.

(3) Securely tighten the oil cap. Insufcient tightening may cause oil leakage.

Note

Do not replace oil with the engine in a tilted position.• Filling with oil while engine is tilted leads to overlling which causes oil contamination and/or white smoke.•

Point 2 in Replacement of oil: “If oil spills out”

If oil spills out between the fuel tank and engine main unit, the oil is sucked into through the cooling air intake port, which will contaminate – the engine. Be sure to wipe out spilt oil before start of operation.

REFUELING

Handling of fuel

It is necessary to handle fuel with utmost care. Fuel may contain substances similar to solvents. Refueling must be performed in a sufciently

ventilated room or in the open air. Never inhale fuel vapor, and keep fuel away from you. If you touch fuel repeatedly or for a long time, the skin becomes dry, which may cause skin disease or allergy. If fuel enters into the eye, clean the eye with fresh water. If your eye remains still irritated, consult your doctor.

Storage period of fuel

Fuel should be used within a period of 4 weeks, even if it is kept in a special container in a well-ventilated and shaded area. Otherwise, fuel may deteriorate in one day.

STORAGE OF MACHINE AND REFILL TANK

Keep the machine and tank at a cool place free from direct sunshine. – Never keep the fuel in a car. –

Fuel

The engine is a four-stroke engine. Be sure to use an unleaded automobile gasoline 87 or higher octane ((R+M)/2). It may contain no more than 10% alcohol (E-10).

Points for fuel

Never use a gasoline mixture which contains engine oil. Otherwise, it will cause excessive carbon accumulation or mechanical troubles. – Use of deteriorated oil will cause irregular start-up. –

Refueling WARNING: Shut off the engine before refueling, keep away from

openamesanddonotsmoke.

Gasoline used: Unleaded automobile gasoline, 87 or higher octane. No more than 10% alcohol (E-10).

Loosen the tank cap a little to release the tank pressure. – Detach the tank cap, and refuel, discharging air by tilting the fuel tank so that –

the refuel port will be oriented upward. DO NOT ll fuel up to the top of the

tank. Wipe the outside of the tank cap to prevent debris from entering into the fuel –

tank. After refueling, securely tighten the tank cap. –

If there is any aw or damage on the tank cap, replace it.• The tank cap wears out in course of time. Replace it every two to three years.• DO NOT put fuel in the oil ll port.•
