5. Maintenance

THB-2500/THB-2510/TBL-4600/4610,TBL-505

Owner’s Manual

MAINTENANCE, REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEM MAY BE
PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

Carburetor adjustment (Fig. 3-1, 1 B, IC)

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)

To adjust, turn IDLE Adjustment Screw (T) in (clockwise) to increase engine speed, out (counterclockwise) to
decrease engine speed.

Standard Idle rpm is 2500-3000rpm.

CAUTION!

The above adjusting procedure must be followed when adjustment is MADE or DAMAGE to engine will occur because of
the incorrect condition.

RECOMMENDATION:

CARBURETOR ADJUSTMENT NEEDS THE SKILL OF EXPERIENCED OR WELL TRAINED PEOPLE. IT IS RECOMMENDED TO
TAKE THE UNIT TO YOUR NEAREST DEALER.

THB-2500/THB-2510/TBL-4600/4610,TBL-505

Air filter

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. (Fig. 3-2)

Owner’s Manual

Cleaning the air filter

Clean the cleaner element every day or every 8 hours of operation. More frequent cleaning is recommended under
very dusty conditions. Wash the element in liquid detergent and water. Squeeze the element to remove the dirt. Press
the element in a dry rag until it is completely dry. Saturate the element in 2-cycle oil or the equivalent. Squeeze the
element to distribute the oil completely and to remove any excess oil. Replace the element and install the cover. (Fig.

3-2B, 2C)

Fuel filter (Fig. 3-3, 3B)

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.

Owner’s Manual

Spark plug (Fig. 3-4)

The spark plug condition is influenced by:

• An incorrect carburetor setting.

• Wrong fuel mixture (too much oil in the gasoline)

• A dirty air filter.

• 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. Readjust if necessary. The correct gap is 0.6 mm (.024”). 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.

Muffler (Fig. 3-5, 5B,5C)

Remove the muffler and clean out any excess carbon from the exhaust port or muffler inlet every 100 hours of
operation.

Cylinder (Engine cooling) (Fig. 3-6, 6B)

The engine is air cooled, and air must circulate freely around engine and over cooling fins on cylinder head to prevent
overheating.

Every 100 Operating hours, or once a year (more often if conditions require), clean fins and external surfaces of engine
of dust, dirt and oil deposits which can contribute to improper cooling.

NOTE!

Do not operate engine with engine shroud or muffler guard removed as this will cause overheating and engine damage.

Spark arrestor

If your unit comes with spark arrestor screen and yet your local regulation requires use of spark arrestor for prevention
against a possible fire, please attach it to the muffler by removing muffler protector and other related parts.

(The spark arrestor meets the regulation of SAE J335-SEP90 and CSA CAN3-Z62. 1 -M77)
