Frequently Asked Questions - TCG27EBDP Tanaka

What type of fuel to use for the Tanaka TCG27EBDP?

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

How to start the trimmer?

Set the on/off switch to the forward position, press the primer bulb several times, set the choke lever to the START (closed) position, then pull the starter cord briskly. As soon as it tries to start, move the choke to the open position and pull again.

What essential safety precautions should be followed?

Always wear a face shield, safety glasses, hearing protection, gloves, thick trousers, and sturdy shoes. Keep people and animals at least 15 meters away. Never start indoors due to toxic exhaust fumes.

How to adjust the engine idle speed?

The idle speed should be adjusted so that the cutting tool does not rotate at idle. Turn the idle adjustment screw (T) clockwise until the blade starts to rotate, then turn counterclockwise until it stops. The correct idle speed is 2,800 to 3,200 min⁻¹.

How to replace the cutting line on the semi-automatic head?

Remove the housing by pushing the locking tabs, extract the spool and discard the remaining line. Fold a new nylon line (diameter 2.4 mm) in half, hook it into the central groove, wind both halves in the same direction, then pass each end through the stop holes. Reinsert the spool and housing.

What regular maintenance is required?

Clean the air filter daily (more often in dusty conditions). Check and clean the spark plug weekly, adjust the gap to 0.6 mm. Check the angle gear grease level every 50 hours. Clean the fuel filter regularly.

What to do if the engine does not start?

Check the fuel tank: if empty, fill with fresh mixture. If the spark plug is flooded, disconnect it, dry it, and pull the starter several times to expel excess fuel. Clean or replace the spark plug if dirty. Check the fuel filter.

How to safely stop the trimmer?

Slow down the engine and let it idle for a few minutes, then set the on/off switch to the stop position. Wait for the cutting tool to stop completely before setting the machine down.

Can I use a metal wire or other non-recommended accessory?

No, use only Tanaka-recommended nylon cutting lines. Using metal wire or cable can cause dangerous projectiles and damage the machine.

What is the declared sound level guarantee?

The guaranteed sound power level is 111 dB(A) according to directive 2000/14/EC. Always wear hearing protection when using this device.

Carburetor adjustment (Fig. 21)

Fig. 21

WARNING

● The cutting attachment may be spinning during carburetor adjustments.
● Never start the engine without the complete clutch cover and tube assembled! Otherwise the clutch can come loose and cause personal injuries.

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. Be sure the cutting attachment stop turning when the engine idle. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate.

If the cutting attachment still rotates after idle speed adjustment, contact your Tanaka dealer.

NOTE

Standard Idle rpm is 2,800 - 3,200 min ^-1 .

WARNING

When the engine is idling the cutting attachment must under no circumstances rotate.

Air fi Iter (Fig. 22)

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

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

Fig. 22

Cleaning the air fi Iter

Open the air filter cover and the filter (21). 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. 23)

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.

Fig. 23

Spark plug (Fig. 24)

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 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 0.024" (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

Fig. 24

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.

Angle transmission (Fig. 25)

Check angle transmission or angle gear for grease level about every 50 hours of operation by removing the grease filler plug on the side of angle transmission.

If no grease can be seen on the fl anks of the gears, fi ll the transmission with quality lithium based multipurpose grease up to 3/4. Do not completely fill the transmission.
