THICK LOG, LARGER THAN GUIDE BAR LENGTH

Begin by cutting on the opposite side of the log. Pull the

chain saw towards you, followed by previous procedure.

Make a boring cut if the log is close to the ground. Finish

with a top cut. (Fig. 31)

WARNING

KICKBACK DANGER

Do not attempt a boring cut if you are not properly

trained. A boring cut involves the use of the nose of the

guide bar and can result in kickback. (Fig. 32)

IF THE CHAIN SAW GETS STUCK

Stop the engine. Raise the log or change its position, using

a thick branch or pole as a lever. Do not try to pull the chain

saw free. If you do, you can deform the handle or be injured

by the saw chain if the chain saw is suddenly released.

MAINTENANCE

Carburetor adjustment (Fig. 33)

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 ﬁ lter 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 cutting attachment still rotates after idle speed

adjustment, contact Tanaka dealer.

WARNING

When the engine is idling the cutting attachment must

under no circumstances rotate.

NOTE

Do not touch the High speed adjustment (H) and the Low

speed adjustment (L).

Those are only for Tanaka dealer.

If you rotate them, it will cause a serious damage to the

machine.

Air ﬁ lter (Fig. 34)

The air ﬁ lter (39) 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.

Remove the air ﬁ lter cover (40) and the ﬁ lter (39).

Rinse them in warm soap suds. Check that the ﬁ lter is dry

before reassembly. An air ﬁ lter that has been used for some

time cannot be cleaned completely. Therefore, it must

regularly be replaced with a new one. A damaged ﬁ lter must

always be replaced.

Spark plug (Fig. 35)

The spark plug condition is inﬂ uenced by:

○ An incorrect carburetor setting.

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

○ A dirty air ﬁ lter.

○ 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. Readjust

if necessary. The correct gap is 0.6 mm. The spark plug

should be replaced after about 100 operation hours or earlier

if the electrodes are badly eroded.

Oiler port (Fig. 36)

Clean the chain oiler port (41) whenever possible.

Guide bar (Fig. 37)

Before using the machine, clean the groove and oiler port

(42) in the guide bar.

Side case (Fig. 38)

Always keep the side case and drive area clean of saw dust

and debris. Periodically apply oil or grease to this area to

protect from corrosion as some trees contain high levels of

acid.

NOTE

Pull up the front hand guard towards you and release the

brake to remove or install the side case.

Fuel ﬁ lter (Fig. 39)

Remove the fuel ﬁ lter (43) from the fuel tank and thoroughly

wash it in solvent. After that, push the ﬁ lter into the tank

completely.

NOTE

If the fuel ﬁ lter (43) is hard due to dust and dirt, replace it.

Chain oil ﬁ lter (Fig. 39)

Remove the oil ﬁ lter (44) and thoroughly wash it in solvent.

After that, push the ﬁ lter into the tank completely.

NOTE

If the oil ﬁ lter (44) is hard due to dust and dirt, replace it.

Icing protection system (Fig. 40)

This system is to protect carburetor from icing when the unit

is operated in winter time.

1. To activate the icing protection system, remove air

ﬁ lter cover (40). Pull out the shutter (45) from inside the

air ﬁ lter cover and reinstall it in winter time position by

ﬂ ipping the shutter. (Fig. 40-b) This will allow heated air

to ﬂ ow from cylinder side to carburetor cabin through the

opening (46).

NOTE

When spring arrives and carburetor will not suﬀ er from

icing, make sure that the shutter is reinstalled in ordinary

position. (Fig. 40-a)

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.

CHAIN SHARPENING

WARNING

○ Gloves should be used when sharpening chain.

○ Be sure to round oﬀ the front edge to reduce the chance

of kickback or tie-strap breakage.
