○ Align groove (5) on the conic pipe (6) and projection (4) on straight pipe (1) and rotate the conic pipe in place.

OPERATING PROCEDURES

Fuel (Fig. 3)

WARNING

☐ The unit/machine is equipped with a two-stroke engine. Always run the engine on fuel, which is mixed with oil.

Provide good ventilation, when fueling or handling fuel.

☐ Fuel contains highly flammable and it is possible to get the serious personal injury when inhaling or spilling on your body. Always pay attention when handling fuel. Always have good ventilation when handling fuel inside building.

Fuel

○ Always use branded 89 octane unleaded gasoline.

Use genuine two-cycle oil or use a mix between 25:1 to 50:1, please consult the oil bottle for the ratio or Hitachi dealer.

☐ If genuine oil is not available, use an anti-oxidant added quality oil expressly labeled for air-cooled 2-cycle engine use (JASO FC GRADE OIL or ISO EGC GRADE). Do not use BIA or TCW (2-stroke water-cooling type) mixed oil.
○ Never use for four-stroke engine oil or waste oil.

Always start by filing half the amount of fuel, which is to be used. Then add the whole amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of fuel.

Mix (shake) the fuel-mix thoroughly before filling the fuel tank.

Fueling

WARNING

○ Always shut off the engine and let it cool for a few minutes before refueling.
○ Slowly open the fuel tank, when filling up with fuel, so that possible over-pressure disappears.
○ Tighten the fuel cap carefully, after fueling.
○ Always move the unit at least 3 m from the fueling area before starting.
Do not smoke and/or allow flames or sparks near fuel when handling or filling fuel.
○ Always wash any spilled fuel from clothing immediately with soap.
○ Be sure to check for any fuel leakage after refueling.

Before fueling, clean the tank cap area carefully, to ensure that no dirt falls into the tank. Make sure that the fuel is well mixed by shaking the container, before fueling.

Starting

CAUTION

Do not start if the pipe and guard net is obstructed.

1. Check the switch (7) to ON position. (Fig. 4)
   * Push priming bulb (8) about ten times so that fuel flows into carburetor. (Fig. 5)
2. Set choke lever to CLOSED position. (Fig. 6)
3. Pull recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 7)
4. When you hear the engine want to start, return choke lever to RUN position (open). Then pull recoil starter briskly again.

WARNING

Never start or run the engine inside a closed room or building and/or near the inflammable liquid. Breathing exhaust fumes can kill.
○ Do not allow the rope to snap back in and always hold the unit firmly.

NOTE

If engine does not start, repeat procedures from 2 to 4.

1. After starting engine, allow the engine about 2–3 minutes to warm up before subjecting it to any load.
   * If the engine stops and is hard to restart straightaway, allow it to cool before trying again.

Operating blower (Fig. 8)

○ A low speed should be used to blow leaves and dry grass.
○ A medium speed should be used to clean wet leaves and grass.
○ A high speed should be used when moving gravel, dirt or other heavy materials.

WARNING

○ Do not direct discharge of air toward people or pet.
○ The unit should be operated in a well ventilated area.
☐ Never perform assembly or disassembly procedures with engine running or serious personal injury may result.
Never touch muffler, spark plug, or other metallic parts while engine is in running or immediately after shutting off engine.

CAUTION

This blower has been designed and adjusted to be used with all blowing pipes attached. It must never be operated without the straight pipe, and conic pipe.

Stopping (Fig. 9)

Decrease engine speed and run at an idle for a few minutes, then turn off ignition switch.

MAINTENANCE

MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

Carburetor adjustment (Fig. 10)

In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is basically adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility:

T = Idle speed adjustment screw.

Idle speed adjustment (T)

Check that the air filter is clean. If adjustment is required, turn IDLE speed Adjustment Screw (T) close (clockwise) to increase engine speed, open (counterclockwise) to decrease engine speed. Standard Idle rpm is 2800-3200rpm.

RECOMMENDATION

CARBURETOR ADJUSTMENT NEEDS THE SKILL OF EXPERIENCED OR WELL TRAINED PEOPLE, OR IS RECOMMENDED TO TAKE THE UNIT TO HITACHI DEALER.

Air fi Iter (Fig. 11)

The air filter must be cleaned from dust and dirt in order to avoid:

○ Carburetor malfunctions

○ Starting problems

○ Engine power reduction

○ Unnecessary wear on the engine parts

○ Abnormal fuel consumption

Remove the air cleaner cover by pushing and pulling back the tab on the top.

Clean the air filter daily or more often if working in exceptionally dusty areas.

Cleaning the air fi Iter

Open the air filter cover and the filter. Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced.

Fuel fi Iter (Fig. 12)

Drain all fuel from fuel tank and pull fuel filter line from tank. Pull filter element out of holder assembly and rinse element in warm water with detergent.

Rinse thoroughly until all traces of detergent are eliminated. Squeeze, do not wring, away excess water and allow element to air dry.

NOTE

If element is hard due to excessive dirt buildup, replace it.

Spark plug (Fig. 13)

The spark plug condition is influenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air fi lter
○ Hard running conditions (such as cold weather)

These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.6 mm. The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

NOTE

In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.

Maintenance schedule

Below you will find some general maintenance instructions. For further information please contact your Hitachi dealer.
