Fuel

WARNING

This unit 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 terious personal injury when inhaling or spilling on your body.
Always pay attention when handling fuel. Always have good ventilation when handling fuel inside the building.

(Fig. 3)

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 the 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 mix fuel and oil in a separate clean container.

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 overpressure disappears.
Tighten the fuel cap carefully, after fueling.
Always move the unit at least 10 ft (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 leaking 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.

Check the switch (7) to the ON position. (Fig. 4)

Push the priming bulb (8) several times so that fuel flows through the bulb or return pipe (9). (Fig. 5)
Set the choke lever to the CLOSED position. (Fig. 6)
Pull the recoil starter briskly, taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 7)
When you hear the engine want to start, return the choke lever to the RUN position (open). Then pull the 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 the engine does not start, repeat procedures from 2 to 4.
After starting the 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 the discharge of air toward people or pets.
The unit should be operated in a well-ventilated area.
Never perform assembly or disassembly procedures with the engine running or serious personal injury may result.
Never touch the muffler, spark plug, or other metallic parts while the engine is running or immediately after shutting off the 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 blow head.

Hitachi Gas Powered Leaf Blower RB24EAP MAINTENANCE

MAINTENANCE, REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS MAY BE PERFORMED BY ANY NONROAD 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.

carburetor_adjustment_hitachi_gas_powered_leaf_blower_rb24eap.png

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

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

Air filter

(Fig. 11)

The air filter must be cleaned from dust and dirt 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 filter

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 fi lter must always be replaced.

Fuel filter

(Fig. 12)

fuel_filter_hitachi_gas_powered_leaf_blower_rb24eap.png

Drain all fuel from the fuel tank and pull the fuel fi lter line from the tank. Pull the filter element out of the holder assembly and rinse the element in warm water with detergent. Rinse thoroughly until all traces of detergent are eliminated. Squeeze, do not wring, away excess water, an allow the 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 infl uenced 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 diffi culties. If the engine is low on power, diffi cult to start or runs poorly at idling speed, always check the spark plug fi rst. If the spark plug is dirty, clean it and check the electrode gap. Re-adjust if necessary. The correct gap is 0.024˝ (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.
