3. Operating procedures
Fuel (Fig. 2-1)
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
• Always use branded 89 octane unleaded gasoline.
• Use Tanaka two-cycle oil or a quality two-cycle oil at mixing ratio of 25-50:1 (Gasoline (A) : Oil (B)), only for the
state of California at 50:1.
• Never use multi-grade oil (10 W/30) or waste oil.
• Always mix fuel and oil in a separate clean container.
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 trimmer at least 3 m (10 ft.) from the fueling area before starting.
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. Assembly procedures
Assembling (Fig. 1-1)
Connect the bit to drive shaft (1) of the power head and
fix it with the snap pins (2) after setting the fixing pins
(3) and washers (2 pcs. each).
Selection of a Suitable Bit
Choose an auger bit according to material to be bored.
In case of ice boring, use an ice bit. When boring the
earth, use one for earth boring.
Starting
1. Set ignition switch (1) to (RUN) position. (Fig. 2-2)
2. Pull the throttle trigger (2) and keep pushing the throttle lock (3), then slowly release the lever to be locked. (Fig. 2-2)
3. Set choke lever to (CHOKED) position. (Fig. 2-3)
4. Pull the recoil starter handle briskly, taking care to keep the handle in your grasp; and not allowing it to snap back.
(Fig. 2-4)
5. Once the engine is running, move the choke to the run-position. (Fig. 2-3)
NOTE!
At this stage if engine does not start, repeat procedure from 2 to 4.
6. After starting the engine, allow the engine about 2-3 minutes to warm up before subjecting it to any load.

TIA-340
Drilling (Fig. 2-5)
Do not touch the bit when running the engine to avoid unexpected accident. Be sure to turn off the
ignition switch before touching it.
1. Hold the handle firmly with both hands so that you may not be swung by the unit.
WARNING!
2. Locate the edge of bit right on the spot to dig, and then drive the bit.
This is an easy job thanks to the built-in centrifugal clutch.
3. Stop the engine and inspect the unit if abnormal vibration or noise is generated.
Stopping (Fig. 2-6)
Gradually decrease the engine speed to an idle speed, and then slide ignition switch (1) to STOP
position.
4. Long operation of the unit may tire you. Try to take a break from time to time.

WARNING!
The bit may be spinning during carburetor adjustments.
WARNING!
Never start the engine without the complete clutch cover and gear case 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. When the idle speed is correct, the bit will not rotate. If adjustment is
required, close (clockwise) the T-screw, with the engine running, until the bit starts to rotate. Open
(counter-clockwise) the screw until the bit stops. You have reached the correct idle speed when the engine
runs smoothly in all positions well below the rpm when the bit starts to rotate.
If the bit still rotates after idle speed adjustment, contact your service workshop.
NOTE! (Fig. 3-1)
The standard openings (returns) of L/H screws from lightly seated positions are as follows.
WARNING!
When the engine is idling the bit must under no circumstances rotate.
5. Maintenance
MAINTENANCE, REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEMS
MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.
NOTE FOR THE US MARKET!! (Fig. 3-1C)
We would like to inform that the power augers TIA-340
of the US model, which carry the following label on the
unit are different from ones for other market in
carburetor adjustment. Adjustment of Standard openings
of L/H screws are not necessary.

TIA-340
Air filter (Fig. 3-2, 2B)
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 filter daily or more often if working in exceptionally dusty areas.
Cleaning the air filter
Remove 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 by a new one. A damaged filter must always be replaced.
Spark plug (Fig. 3-3)
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 malfunc-
tion 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.

TIA-340
Transmission (Fig. 3-4)
Check transmission or gear for grease level about every
50 hours of operation by removing the grease filler plug
on the side of transmission.
If no grease can be seen on the flanks of the gears, fill
the transmission with a quality lithium based
multipurpose grease up to 3/4.
Do not completely fill the transmission.
Fuel filter (Fig. 3-5)
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 buildu
p,
re
p
lace it.
Cleaning the cylinder fins (Fig. 3-6)
When wood chips are caught between cylinder fins (1), the engine
may overheat, resulting in lower output. To avoid this, always keep
cylinder fins and fan case clean.
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.
Cleaning the muffler (Fig. 3-7)
Remove the muffler and spark arrestor (if so equipped), and clean out any
excess carbon from the exhaust port or muffler inlet every 100 hours of
operation.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until it stops.
Repair any damage which has resulted from use. Clean the unit with a
clean rag, or the use of high pressure air hose. Put a few drops of
two-cycle engine oil into the cylinder through the spark plug hole, and spin
the engine over several times to distribute oil. Cover the unit and store it
in a dry area.
