• To avoid head-, eye-, hand or foot injuries as well as to protect your hearing the following protective equipment and protective clothing must be used during the operation of the blower. Pay particular attention to the following regulations

• Clothing must be sturdy and snug-fitting, but allow complete freedom of movement. Avoid loose-fitting jackets, flared or cuffed pants, scarves, unconfined long hair or anything that could be drawn into the air intake. (4) Wear overalls or long pants to protect your legs.
  Do not wear shorts. (4)

• Generally, engine products are noisy and their noise may damage your hearing. Wear sound barriers (ear plugs or ear mufflers) to protect your hearing. Continual and regular users should have their hearing checked regularly. (3)

• Use of gloves when working with the blower is recommended. Wear sturdy shoes with non-slip soles. (4)

• Proper eye protection is a must. Even though the discharge is directed away from the operator, ricochets and bounce-backs can occur during blower operation. (3)

• Never operate a blower unless wearing goggles or properly fitted safety glasses with adequate top and side protection which comply with ANSI Z 87.1 and regulations in your country.

• To reduce the risk of injury associated with the inhalation of dust, use a face filter mask in dusty conditions.

Starting up the blower

• Clear the area of children, bystanders, and pets. At a minimum, keep all children, bystanders, and pets outside a 15 m (50 ft) radius; outside the 15 m (50 ft) zone, there is still a risk of injury from thrown objects. Bystanders should be encouraged to wear eye protection. If you are approached, stop the engine.

• Before operating, always check that the blower is safe for operation: Check the security of the throttle lever. The throttle lever should be checked for smooth and easy action. Check for proper functioning of the throttle lever lock. Check for clean and dry handles and test the function of the l-O switch. Keep handles free of oil and fuel.

• Start the Blower only by the instructions. Do not use any other methods for starting the engine (6).

• Use the blower and the tools supplied only for the applications specified.

• Start the blower engine only after the entire tool has been assembled. Operation of the tool is permitted only after all the appropriate accessories are attached.

• The engine is to be switched off immediately if there are any engine problems.

• When working with the blower, always wrap your fingers tightly around the handle, keeping the control handle cradled between your thumb and forefinger. Keep your hand in this position to have your machine under control at all times. Make sure your control handle is in good condition and free of moisture, pitch, oil or grease. Always ensure a safe, well-balanced footing.

• Carry the blower properly on both shoulders during the operation. Do not carry the blower with only one shoulder strap. Otherwise, personal injury may result.

• Operate the blower in such a manner as to avoid inhalation of the exhaust gases. Never run the engine in enclosed rooms (risk of suffocation and gas poisoning). Carbon monoxide is an odorless gas. Always ensure there is adequate ventilation.

• Switch off the engine when resting or leaving the blower unattended. Place it in a safe location to prevent danger to others, setting fire to combustible materials, or damage to the machine.

• Never lay the hot blower onto dry grass or any combustible materials.

• All protective parts and guards supplied with the machine must be used during operation.

• When transporting the blower, ensure that the fuel tank is empty.

• Carry the blower by its carry handle. Do not drag the blower by the nozzle, pipe, or other parts.

• When transporting the blower, bend your knee and make sure you do not damage your shoulder and lower back.

Refuelling

• Shut off the engine during refueling (7), keep well away from the open flame (8), and do not smoke.
• Avoid skin contact with petroleum 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 to prevent soil contamination (environmental protection). Clean the blower immediately after the fuel has been spilled. Allow wet cloths to dry before disposing in a properly, covered container to prevent spontaneous combustion.
• Avoid any fuel contact with your clothing. Change your clothing immediately if fuel has been spilled on it (fire hazard).
• Inspect the fuel cap at regular intervals making sure that it stays securely fastened.
• Carefully tighten the locking screw of the fuel tank. Change locations to start the engine (at least 3 meters (10 ft) away from the place of refueling) (9).
• 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.

Method of operation

• Use the blower only in good light and visibility. Beware of slippery or
  wet areas, ice and snow (risk of slipping), and narrow spaces. Always ensure a safe footing.

• Never work on unstable surfaces or steep terrain.

• Do not work from ladders or high places. Otherwise, it may result in personal injury.

• To reduce the risk of personal injury, do not direct the air blast toward bystanders, since the high pressure of the air flow could injure eyes and could blow small objects at great speed.

• Never insert any foreign object into the air intake of the machine or the nozzle of the blower. It will damage the fan wheel and may cause serious injury to the operator or bystanders as a result of the object or broken parts being thrown out at high speed.

• Pay attention to the direction of the wind, i.e., do not work against the wind.

• To reduce the risk of stumbling and loss of control, do not walk backward while operating the machine.

• Always shut off the engine before cleaning or servicing the unit or replacing parts.

BEFORE STARTING THE ENGINE

Checking and Refilling Engine Oil

1. Follow the procedure below when the engine oil is cold i.e. the blower has not been running.

   • Inspection: Set the blower down on a level surface and remove the oil cap.
     Make sure that the oil level is within the upper and lower limit marks on the oil level gauge. If the oil is not up to the 100mL level, fill up with new oil.

   • Adding Oil : Set the blower down on a level surface and remove the oil cap.
     Fill the oil up to the upper limit of the oil level gauge.

2. On average, engine oil normally needs to be added after every 20 hours of operation. This interval for every oil change corresponds to refueling the blower approximately 10-15 times.

3. Please change the oil whenever it becomes dirty or significantly changes color. (Refer to p.15 for the oil change procedure and frequency.)

• Recommended oil: Makita genuine oil or SAE10W-30 oil of API type SF grade or better (4-stroke motor oil for automobiles)
• Oil capacity: Approximately 0.22 L (220 ml)

CAUTION

• If the blower is not stored in an upright position, the oil may flow from the level gauge into the engine and give a false reading when checking the oil level. This may result in inadvertently overfilling whenever adding engine oil. Always store in an upright position.
• If the upper oil level limit is exceeded, the oil may become dirty, and white smoke may appear due to burning excessive oil.

Check Point # 1: The oil cap

• Wipe off dirt and grime around the opening before removing the oil cap.
• Remove the oil cap and place it on a clean surface so that it does not accumulate any sand, dirt, or other foreign materials. These may stick to the cap and adulterate the engine oil. Dirty oil containing sand, dirt, or foreign materials may cause excessive wear on the engine due to improper lubrication and cause a breakdown.

Check Point # 2: Oil spillage
Oil spillage on the outside of the blower may cause the engine oil to become dirty or adulterated. Therefore, please wipe off any oil spillage before starting the engine.

Fuel supply

WARNING

• When refueling the unit, be sure to observe the following instructions to prevent ignition or fire:
  • Fuel supply must be made in a place free of fire. Never bring the fire (smoking, etc.) near the place of fuel supply.
  • Stop the engine and allow the engine to cool down before refueling.
  • Open the fuel tank cap slowly. The fuel may be spilled out under internal pressure.
  • Take care not to spill the fuel. Any spilled fuel must be wiped clean.
  • Carry out fuel supply in a well-ventilated place.
• Handle the fuel with care.
  • Fuel sticking to the skin or entering an eye may cause allergies or irritation. When any physical abnormality is detected, consult the medical specialist immediately.
• DO NOT put oil in the fuel tank.

STORAGE PERIOD OF FUEL
Fuel should be used within 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 automobile gasoline (regular gasoline or premium gasoline).

Points for Fuel

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

When refueling, stop the engine and wait for the engine to cool down.

REFUELLING METHOD

• 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 fill fuel up to the top of the tank.
• After refueling, securely tighten the tank cap.
• If there is any flaw or damage on the tank cap, replace it.
• The tank cap wears out over time. Replace it every two to three years.
• DO NOT put fuel in the oil fill port.

OPERATION

Starting

WARNING

• Never attempt engine start in a place where the fuel has been supplied.
  • It may cause ignition or fire. When starting the engine, keep a distance of at least 3 m.
• Exhaust gas from the engine is toxic. Do not operate the engine in a poorly ventilated place, such as in a tunnel, building, etc.
  • Operating the engine in the poorly ventilated place may cause poisoning by exhaust gas.
• In case of detection of any abnormality in sound, odor, or vibration after starting, stop the engine immediately and carry out an inspection.
  • If the engine is operated without attending to such abnormality, an accident may occur.
• Make sure that the engine stops when the stop switch is set to the “O” position.

When the engine is cold or after refueling

2. Adjusting the control lever

   • Move the control handle along the swivel pipe to the most comfortable position.

3. Blower Operation
   While operating the blower, adjust the throttle bar so that the wind force is appropriate for the work location and conditions.

   • Low speed: Dried leaves and grass
   • High speed: Gravel and dirt

The cruise control lever allows the operator to maintain a constant engine speed without operating the trigger lever.

• Lifting the cruise control lever increases engine speed.
• Lowering the cruise control lever decreases engine speed.

Adjusting engine speed when the cruise control lever is being used:

When increasing engine speed:

• Pull the trigger lever to increase engine speed. Engine speed returns to its original setting when the trigger lever is released.
• Increasing the engine speed in this manner also increases the cruise control setting. The cruise control lever lifts simultaneously as the trigger lever is pulled, and the new cruise control setting will be maintained at the higher engine speed.

When reducing engine speed:

• Lower the cruise control lever to the low-speed position.

TRANSPORTING AND STORING THE BLOWER
Please maintain the blower in an upright position whenever transporting or storing. (Refer to Figure at right.)
Transporting or storing in a position that is not upright may cause oil to spill inside the blower engine. This may result in oil leaks and white smoke from burning oil, and the air cleaner may become dirty with oil.

DANGER: When transporting the blower, be sure to stop the engine.

• Before inspection and maintenance, stop the engine and allow it to cool down. Remove the spark plug and plug cap.
  • Otherwise, the operator may suffer a burn or serious injury due to an accidental start-up.
• After inspection and maintenance, make sure that all parts are assembled. Then, proceed to operation.

Replacement of engine oil
Deteriorated engine oil will shorten the life of the sliding and rotating parts to a great extent. Be sure to check the period and quantity of replacement.

DANGER

• In general, the engine main unit and engine oil remain hot just after the engine is stopped. In replacement of oil, make sure that the engine main unit and engine oil are sufficiently cooled down. Otherwise, there may remain a risk of scald. Allow sufficient time after stopping the engine for the engine oil to return to the oil tank to ensure an accurate reading of the oil level indicator.
• If the oil is filled above the limit, it may become dirty or may catch fire with white smoke.

Interval of replacement: After the first 20 operating hours, followed by every 50 operating hours
Recommended oil: SAE10W-30 oil of API Classification SF Class or higher (4-stroke engine oil for the automobile)

Oil Change Proced ure
Please follow these steps when changing the oil:

1. Set the blower down on a level surface.

2. Put a waste oil container under the drainage hole (1) to catch the oil as it drains out. The container should have a capacity of at least 220 ml to be able to catch all of the oil.

3. Loosen the oil drain bolt (2) to let the oil drain out. Be careful not to allow oil to get on the fuel tank or other parts.
   Caution: Be careful not to lose the gasket (aluminum washer) (3). Put the oil drain bolt (2) in a location where it will not accumulate dirt.

4. Remove the oil cap (4). (Removing the oil cap (4) allows the oil to drain easily.)
   Caution: Be sure to set the oil cap (4) down in a location where it will not accumulate dirt.

5. As the level of the oil being drained decreases, tilt the blower over on to the side with the drain so that the oil will completely drain out.

6. After the oil has completely drained out, tighten the oil drain bolt (2) securely. If the bolt is not tightly fastened, this may result in an oil leak.
   Caution: Do not forget to put the gasket (aluminum washer) (3) back on whenA reattaching the drain plug.

7. Adding oil during the oil change procedure is performed in the same man-ner as the separately explained procedure for adding oil whenever the level is insufficient. Always add oil by filling from the opening under the oil cap.
   Specified oil level: Approximately 220 ml)

8. After filling with oil, tighten the oil cap (4) securely to prevent oil leaks.

Points in replacement of engine oil

• Never discard replaced engine oil in garbage, earth or sewage ditch. Disposal of oil is regulated by law. In disposal, always follow the relevant laws and regulations. For any points remaining unknown, contact the Authorized Service Agent.
