Frequently Asked Questions - TRB24EAP HiKOKI

How to start the TRB24EAP blower?

Make sure the switch is ON. Press the primer bulb about 10 times. Set the choke to closed. Pull the starter cord vigorously. At the first sputter, move the choke to open and pull again.

What type of fuel to use?

Use a mixture of unleaded gasoline (octane rating 89) and 2-stroke engine oil (JASO FC or ISO EGC quality) at a ratio of 25:1 to 50:1. For California, 50:1 ratio only.

How to adjust idle speed?

Adjustment is done with the carburetor T screw. Turn it clockwise to increase speed or counterclockwise to decrease. Normal idle is 2,800 to 3,200 rpm. Call a professional if needed.

How to clean the air filter?

Remove the filter cover by pushing the tab. Wash the filter in warm soapy water, rinse and dry completely before reinstalling. Replace if damaged or very dirty.

How to replace the spark plug?

Disconnect the spark plug wire. Use a spark plug wrench to remove it. Check the electrode gap: 0.6 mm. Replace with a NGK BMR7A or equivalent spark plug. Tighten by hand then 1/4 turn.

What safety precautions to take?

Wear safety glasses, helmet and hearing protection. Keep people at least 15 m away. Do not direct the blast at people. Do not touch hot surfaces. Use outdoors only.

How to assemble the blower tubes?

Align the tab of the straight tube with the groove of the housing, push in and turn clockwise to lock. For the tapered tube, align its groove with the tab of the straight tube and turn to secure.

What to do if the engine does not start?

Check the switch (ON position), fuel (correct mixture), spark plug (clean and gap), air filter (clean). If the engine stalls, let it cool for a few minutes before trying again.

How to store the unit?

Empty the fuel tank. Let the engine cool. Clean the unit. Store in a dry place, out of reach of children. Make sure the switch is on STOP.

What is the sound power of the blower?

The sound power level (LwA) is 109 dB(A) according to directive 2000/14/EC. The sound pressure level (LpA) is 87 dB(A) according to CEN standard.

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 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 Tanaka dealer.
○ Only for the state of California at 50:1.
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 fi ling 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

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.

T

Fig. 10

Idle speed adjustment (T)

Check that the air fi Iter 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, IR IS RECOMMENDED TO TAKE THE UNIT TO Tanaka DEALER.

Air fi Iter (Fig. 11)

The air fi lter 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 fi lter daily or more often if working in exceptionally dusty areas.

Fig. 11

Cleaning the air fi Iter

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

Fuel fi Iter (Fig. 12)

Drain all fuel from fuel tank and pull fuel fi lter line from tank. Pull fi lter 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.

Fig. 12

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 Iter
○ 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.

0.024" (0.6 mm)

Fig. 13

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.
