2. Selection of a suitable auger

1) Choose an auger according to material to be bored. (Example) of ice boring, use an ice auger. When boring the earth, use one for earth boring. (For more information, ask your nearest dealer).

3. Filling the fuel

WARNING!

- Do not use fuel with more than 10% ethanol in this unit.

Use of fuel, such as E15 (15% ethanol), E20 (20% ethanol), E85 (85% ethanol), may cause problems including overheating, premature deterioration of fuel lines and carburetors. Use of fuel with more than 10% ethanol may result in personal injury or property damage. Use of fuel with more than 10% ethanol will void the product warranty. Check the ethanol level before purchasing fuel for this unit.

WARNING!

• The power auger 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 multi-grade oil (10 W/30) or waste oil.
• Always mix fuel and oil in a separate clean container.

(6) 1: Oil

(7) 25\~50: Gasoline

Always start by filling 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 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 (10 ft.) from the fueling area before starting.
• Always Wash any spilled fuel from clothing immediately with soap.
- Be sure to check 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.

4. Starting

1) Switch on both stop switches. (M.Parts)
2) Turn choke lever (1) to CHOKE position. (Fig. 4)
3) Pull throttle lever and push on lock-button, then slowly release the throttle lever. This will lock the throttle. Meanwhile, the other operator must keep squeezing the other throttle lever fully. (M.Parts)
4) Operator at starter handle side pulls recoil starter briskly taking care to keep the handle in your grasp and not allowing it to snap back. (Fig. 5)

(2) Starter handle

5) When you hear the engine want to start, return choke lever to RUN position (open). Then pull the recoil starter briskly again. (Fig. 4)

NOTE:

If engine does not start, repeat procedures from 2 to 5.

6) After starting the engine, pull the throttle lever to release lock button.

Then, allow the engine about 2-3 minutes to warm up before subjecting it to any load.

NOTE:

To accelerate the engine both throttle levers must be pulled at the same time. As soon as one operator releases throttle lever, it decelerates engine. (This is normal condition)

CAUTION:

It is not recommended that the cable adjuster be touched as it is factory adjusted.

5. Carburetor adjustment (Fig. 6)

WARNING!

Never start the engine without the complete clutch cover. 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 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. 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 bit still rotates after idle speed adjustment, contact Tanaka dealer.

(T) Idle adjusting screw
(3) Carburetor

WARNING!

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

NOTE!

Some models sold areas with strict exhaust emission regulation do not have high and low speed carburetor adjustments. Such adjustments may allow the engine to be operated outside of their emission compliance limits. For these models, the only carburetor adjustment is idle speed.

For models that equipped with low and high speed adjustments; carburetors are pre set at the factory

Minor adjustments may optimize performance based on climate, altitude, etc. Never turn the adjustment screws in increments greater than 90 degrees, as engine damage can result from incorrect adjustment If you are not familiar with type of adjustment-assistance Tanaka dealer.

6. Drilling

1) Both operators must hold the handle firmly with both hands and stand firmly on solid ground so that you may not be swung by the unit. (Fig. 5)
2) Locate the edge of auger right on the spot to dig and then drive the auger at full throttle for digging. This is an easy job thanks to the built-in centrifugal clutch. (Fig. 5)
3) Raise auger slightly after every few inches of digging to relieve pressure and clean out the hole.
4) The clutch is made to slip when the auger is overloaded. When this happens, raise the auger slightly to ease load.

WARNING!

While drilling, the auger may twist suddenly and forcefully if it contacts large rocks, roots, or other hidden obstacles.

Release throttle trigger immediately, and lift auger out of hole. Clear the obstacles to prevent damage, and then resume drilling.

5) When abnormal vibration or noise is generated, stop the engine and inspect the unit.

CAUTION:

Since TEA-500 is designed as a TWO-PERSON auger, never attempt to make auger work with only one throttle lever control.

6) When auger is stuck while digging, and hard to pull out from ground, stop engine and lock the auger by the lock pin which may make the job easier. (Fig. 8)

(4) Lock pin
(5) Lock pin handle

(The lock pin setting is made by turning powerhead slightly while pushing the pin. Then twist the pin handle clockwise to lock.)

7. Stopping

1) One or both of the two operators release throttle lever gradually to an idle position, then turn off stop switch or button. (M.Parts)

NOTE:

In case of an emergency, just turn off stop switch immediately.

2) Close fuel cock and drain fuel system for prolonged storage.

Maintenance

1. Periodical check

1) Clean the air cleaner element with soap and water and dry before reuse. (Fig. 9)

(1) Air cleaner cover
(2) Pull to remove air Cleaner cover
(3) Air cleaner element

2) Scrape off the carbon from the spark plug gap. (Standard gap is 0.60 mm or 0.023 in.) (Fig.10)

(4) 0.60 mm .023 in
(5) Remove carbon or oil

3) Inspect carefully for any fuel or oil leaks.
4) Check all nuts, bolts, screws, etc. making sure they are tightened.
5) Since the clutch shoes will wear after a long period of use, it should be checked occasionally.

2. Lubrication

1) Lubricate gear case by pumping multi-purpose grease through grease fitting every 50 hours of operation. (Fig. 11)

(6) Grease fitting

2) Engine speed governor is lubricated with # 30 weight oil (EP lithium). The capacity is 0.5 fl.oz. (16ml) and should be checked every 50 hours of use at the level check screw. (Fig. 12)

(7) Level check screw

When unscrewing the check screw, keep the screw side up.

3. Governor adjustment

1) Frist with the engine off, loosen screw A (1). Pull up governor outer lever (2) and push down governor spring lever (3), then at the same time retighten the screw A (Fig. 12B)

NOTE:

After above procedure, make sure the throttle (4) on the carburetor gets either of the idle position or the full open position.

2) To adjust governor, loosen screws (6) which holds control lever assembly (5) to crankcase and move the assembly left or right to obtain the maximum speed of 6500 rpm (Moving control lever assembly to left gives higher rpm and moving to right, lower rpm) (Fig. 12C)

NOTE:

Always adjust throttle wire end play before governor adjustment.

CAUTION:

Do not adjust to run more than 6500 rpm.

3) Governor hunting (Varying rpm)

• Hunting occurs with insufficient warm up of engine.
• When the governor spring, governor rod or governor rod spring moves improperly, hunting may occur. Check and clean.
• If governor rod spring becomes stretched, hunting may occur. Handle with care or replace.
• If the gosoline and oil mix ratio is not correct, hunting may occur. Ratio should be from 25:1 to 50:1.
• When fuel tank or petcock is clogged with dirt or old fuel, hunting may occur. Check and clean.
• When there is insufficient oil in the governor, the weights will not operate properly, resulting in hunting. Check and refill with gear oil.
• If the high speed screw on the carburetor is improperly adjusted, hunting may occur. Adjust properly.

4. Other features

1) By folding the handle bars upward, they can be used as a carrying handle. (Fig. 13)
2) By folding the handle downward, they become a stand for storage. (Fig. 14)
