3. SAFETY PRECAUTIONS

■

WARNING CONSIDERING

HANDLING OF FUEL a. The engine of this product is designed to run on a mixed fuel which contains highly flammable gasoline. You should never store cans of fuel or refill the fuel tank in any place where there is a boiler, stove, wood fire, electrical sparks, welding sparks, or any other source of heat or fire which might ignite the fuel.

b. Smoking while operating the hedge-trimmer or refilling its fuel tank is extremely dangerous.

Always be sure to keep lit cigarettes away from the hedgetrimmer at all times.

c. When refilling the tank always turn off the engine first and take a careful look around to make sure that there are no sparks or open flames anywhere nearby before refueling.

d. If any fuel spillage occurs during refueling, use a dry rag to wipe up spills before turning the engine back on again.

e. After refueling, screw the fuel cap back tightly onto the fuel tank and then carry the hedge-trimmer to a spot 3m or more away from where it was refueled before turning on the engine.

■

THINGS TO CHECK BEFORE

USING YOUR HEDGE-TRIMMER a. Before beginning work, look around carefully to get a feel for the shape of the land, or grass to be trimmed, and whether or not there are any obstacles which might get in the way while working, and remove any obstacles which can be cleared away.

b. The area within a perimeter of

15m of the person using the hedge-trimmer should be considered a hazardous area into which no one should enter while the hedge-trimmer is in use, and when necessary yellow warning rope, warning signs should be placed around the work area.

When work is to be performed simultaneously by two or more

13

14

English

3. SAFETY PRECAUTIONS persons, always check the presence and locations of others so as to maintain a distance each person sufficient to ensure safety.

c. Make sure that there are no loose screws or bolts, fuel leaks, ruptures, dents, or any other problems which might interfere with safe operation. Be especially careful to check that there is nothing wrong with the blades or with the joints by which the blades are attached to the hedgetrimmer.

d. Never use blades that are bent, warped, cracked, broken or damaged in any way.

e. Keep the blade always sharp.

f. Filing the cutting edges, keep the end corner sharp and round the root of the edge.

g. Check the bolt to fasten the blade and be sure the blade turns smoothly without abnormal noise.

■

NOTES ON STARTING THE

ENGINE

1. Take a careful look around to make sure that no obstacles exist within a perimeter of 15m or less around hedge-trimmer.

2. Place the body of the hedgetrimmer onto the ground in a flat clear area and hold it firmly in place so as to ensure that neither the blades nor the throttle come into contact with any obstacles when the engine starts up.

3. Place the throttle into the idling position when starting the engine.

4. After starting up the engine, if the blades continue to rotate even after the throttle has been moved fully back, turn off the engine and check the throttle wire and other parts.

3. SAFETY PRECAUTIONS

■

KICKBACK SAFETY PRECAUTIONS

• A dangerous reaction may occur when the spinning blade contacts a solid object in the critical area.

It is called Kick back. As a result, the operator can lose control of the unit which can cause serious or fatal injury.

Avoid kickback, observe the safety precautions below strictly.

1. Keep the cutting blades clear of fances, posts, wires, and rocks to prevent kickback and damage to the blades.

2. When using your hedge-trimmer, do not grip other parts except the handles.

3. When using your hedge-trimmer, never take your eyes off. If you need to, place the throttle into the idling position.

4. When using your hedge-trimmer, do not let the unit get closer to your feet nor raise the unit above your waist.

■

NOTES ON TRANSPORTATION a. Make sure the appropriate blade cover is in place.

b. When transporting by car, fix the unit firmly using a rope. Do not transport by bicycle or motorbike because it is dangerous.

c. Never transport the hedgetrimmer over rough roads over long distances without first removing all fuel from the fuel tank, as doing so might cause fuel to leak from the tank.

■

OPERATION SAFETY PRECAUTIONS a. Grip the handles of the hedgetrimmer firmly with both hands. If you suspend the work, place the throttle into the idling position.

b. Always be sure to maintain a steady, even posture while working.

c. Maintain the speed of the engine at the level required to perform cutting work, and never raise the speed of the engine above the level necessary.

English

3. SAFETY PRECAUTIONS d. If the grass gets caught in the blade during operation, or if you need to check the unit or refuel the tank, always be sure to turn off the engine.

e. If the blade touches a hard object like a stone, immediately stop the engine and check if something is wrong with the blade. If so, replace the blade by new one.

f. If someone calls out while working

,always be sure to turn off the engine before turning around.

g. Never touch the spark plug or plug cord while the engine is in operation. Doing so may result in being subjected to an electrical shock.

h. Never touch the muffler, spark plug, or other metallic parts of the engine while the engine is in operation or immediately after shutting down the engine. Doing so may result in serious burns.

i. When you finish cutting in one location and wish to continue work in another spot, turn off the engine and turn the unit as the blade faces away from your body.

■

4. FUEL

WARNING

• Gasoline is very flammable.

Avoid smoking or bringing any flame or sparks near fuel.

• Wipe up all spills before starting the engine.

• Make sure to stop the engine and allow it cool before refueling the unit.

• Keep open flames away from the area where fuel is handled or stored.

IMPORTANT

• Never use oil for 4 cycle engine use or water cooled 2-cycle engine.

• Never use "FUEL WITH NO OIL

(RAW GASOLINE)".

• Never use fuel laced with water.

• Mixed fuels which have been left unused for a period of one month or more may clog the carburetor or result in the engine failing to operate properly. Put remained fuel into an air-tight container and keep it in the dark and cool room.

• Please ask for “mixed gasoline for air-cooled 2-cycle engines” at your nearest gas station, or use fuel made by putting unleaded gasoline for automobiles and aircooled 2-cycle engine oil into a mixing container in accordance with the following ratios and then shaking to mix well.

Mixing ratios:

When using Zenoah genuine 2-cycle oil (FC grade):

50:1 (100 ml of oil for every 5 liters of gasoline)

When using commercially available

2-cycle oil (FB grade):

25:1 (160 ml of oil for every 4 liters of gasoline)

CUTTING WORK

WARNING

• Weather conditions and altitude may effect carburation.

• Do not allow anyone to stay close to the hedge-trimmer while working or while adjusting the carburetor.

■

HOW TO USE

HANDLE [eHT601D only] (F5)

To reduce fatigue when trimming hedges, the handle can be swivelled through 90° to the left or right.

Do not press the throttle during this operation!

Proceed as follows:

1. Free the handle by pressing the locking lever.

2. Turn the handle until the locking lever clicks into place.

3. When the handle is locked in its new position, you can apply the throttle again.

(1) Handle

(2) Locking lever

• Use only as much throttle as is needed to do the job. Excessive engine speed is unnecessary.

• Avoid cutting thick branches, for which will damage the blades and shorten the life of drive systems.

• Tilting the trimmer 5 to 10° to the cutting object will make the job easy and bring a good result.

• Always keep your body to the carburetor side of your trimmer, never on the muffler side.

• When a new machine is first operated, in the first few minutes grease may come out of the gear case. But, since this is excess grease, there is no cause for alarm. Just wipe it off with the engine stopped for next use.
