AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these sub-

stances repeatedly and for an extended period of time, it will desiccate. Various skin

deseases may result. In addition, allergic reactions are known to occur. Eyes can be

irritated by contact with oil. If oil comes into your eyes, immediately wash them with

clear water.

If your eyes are still irritated, see a doctor immediately!

Chain oil

Use an oil with adhesive additive for lubricating the chain and guide

bar. The adhesive additive prevents the oil from being flung off the

chain too quickly.

We recommend the use of chain oil which is bio-degradable in order to

protect the environment. The use of bio-degradable oil may even be

required by local regulations.

The chain oil BIOTOP sold by DOLMAR is made of special vegetable oils and is

100% bio-degradable. BIOTOP has been granted the “blue angel” (Blauer Umwelts-

chutz-Engel) for being particularly environment-friendly (RAL UZ 48).

BIOTOP chain oil is available in the following sizes:

1 l order number 980 008 210

5 l order number 980 008 211

Bio-degradable oil is stable only for a limited period of time. It should

be used within 2 years from the date of manufacture (printed on the

container).

Important note on bio-degradable chain oils:

If you are not planning to use the saw again for an extended period of time, empty the

oil tank and put in a small amount of regular engine oil (SAE 30), and then run the

saw for a time. This is necessary to flush out all remaining bio-degradable oil from the

oil tank, oil-feed system, chain and guide bar, as many such oils tend to leave sticky

residues over time, which can cause damage to the oil pump or other parts.

The next time you use the saw, fill the tank with BIOTOP chain oil again. In case of

damage caused by using waste oil or inappropriate chain oil the product guarantee

will be null and void.

Your salesman will inform you about the use of chain oil.

NEVER USE WASTE OIL (Fig. 38)

Waste oil is very dangerous for the environment.

Waste oil contains high amounts of carcinogenic substances. Residues in waste oil

result in a high degree of wear and tear at the oil pump and the sawing device.

In case of damage caused by using waste oil or unappropriate chain oil the product

guarantee will be null and void.

Your salesman will inform you about the use of chain oil.

Refuelling (Fig. 39)

FOLLOW THE SAFETY PRECAUTIONS!

Be careful and cautious when handling fuels.

The engine must be switched off!

Thoroughly clean the area around the caps, to prevent dirt from getting into the fuel or

oil tank.

Unscrew the cap and fill the tank with fuel (fuel/oil mixture) or chain oil as the case

may be. Fill up to the bottom edge of the filler neck. Be careful not to spill fuel or chain

oil!

Tighten the fuel caps far as it will go.

Clean screw cap and tank after refuelling.

Lubricating the chain

During operation there must always be sufficient chain oil in the

chain-oil tank to provide good chain lubrication. One filling is suffi-

cient for about one half-hour of continuous operation. When working,

check that there is still sufficient chain oil in the tank and top up if

necessary. Check only when the engine is switched off!

1 fuel/oil mixture

2 chain oil

Adjusting the chain lubrication (Fig. 40)

The engine must be switched off.

You can adjust the oil pump feed rate with the adjusting screw (1).

The amount of oil can be adjusted using the universal wrench.

To ensure troublefree operation of the oil pump the oil guide groove

at the housing (2) and the oil inlet bore in the guide bar (3) must be

cleaned regularly. (Fig. 41)

Checking the chain lubrication (Fig. 42)

Never work with the chain saw without sufficient chain lubrication. Otherwise the ser-

vice life of the chain and guide bar will be reduced.

Before starting work check the oil level in the tank and the oil feed.

Check the oil feed rate as described below: Start the chain saw (see “Starting the

engine”).

Hold the running chain saw approx. 15 cm above a trunk or the ground (use an appro-

priate base).

If the lubrication is sufficient, you will see a light oil trace because oil will be flung off

the sawing device. Pay attention to the direction the wind is blowing and avoid unnec-

essary exposure to the oil spray!

NOTE:

After the saw has been turned off it is normal for residual chain oil to drip from the oil

feed system, the guide bar and the chain for a time. This does not constitute a defect!

Place the saw on a suitable surface.

Starting the engine (Fig. 43)

Do not start the saw until it has been completely assembled and inspected!

Move at least 3 m away from the place where you fuelled the saw.

Make sure you have a good footing, and place the saw on the ground in such a way

that the chain is not touching anything.

Engage the chain brake (lock).

Grasp the rear handle firmly in one hand and hold the saw firmly against the ground.

Press with one knee on the rear handle.

IMPORTANT: The choke lever (5) is coupled to the throttle lever (1). It will revert to its

original position automatically once the throttle lever has been pressed.

If the throttle lever is pressed before the engine starts, then the choke lever (5) will

have to be reset to the appropriate position. (Fig. 44)

Cold start:

Push the short-circuit switch (3) forward.

Turn the choke lever (5) to position . Push primer pump 7 – 10 times.

Slowly pull out the starter cable (4) until you notice resistance (the piston is positioned

before the top dead centre). (Fig. 44)

Now continue to pull quickly and powerfully. The engine will start after 2 to 4

attempts and will continue to run (at low temperatures, several starting pulls might be

necessary).

CAUTION: Do not pull out the starter cable more than approx. 50 cm, and lead it back

by hand. For efficient starting, it is important to pull the starter cable quickly and pow-

erfully.

As soon as the engine is running smoothly, gently press the throttle lever (1) once

(grasp the handle, the safety locking button (2) will release the throttle lever) this will

cause the choke lever (5) to spring back to its original position and the engine will

then run at idling speed. (Fig. 44)

Now release the chain brake

Warm start:

Proceed as described under cold start, but place the choke lever (5) to

position

. (Fig. 44)

Important: If the fuel tank has been completely emptied and the engine has stopped

due to lack of fuel, press the primer pump 7 – 10 times. (Fig. 44)

Stopping the engine

Put the short-circuiting switch (3) in position “STOP”. (Fig. 44)

Checking the chain brake (Fig. 45)

Do not work with the chain saw without first checking the chain brake!

Start the engine as described (make sure you have a good footing, and place the

chain saw on the ground in such a way that the guide bar is free of contact).

Grasp the tubular handle firmly with one hand and hold the grip with the other.

With the engine running at moderate speed, press the hand guard (6) in the direction

of the arrow with the back of your hand until the chain brake engages. The chain

should stop immediately.

Immediately release the throttle and release the chain brake.

IMPORTANT: If the chain does not stop immediately in this test, do not under

any circumstances proceed with work. Contact a DOLMAR service center.

Adjusting the carburetor (Fig. 46)

The carburetor eliminates the need to adjust the idle and main nozzles, and no such

adjustment is possible.

If necessary, the idle speed can be adjusted using the adjustment screw (11).

As installed, the carburetor has fixed nozzles for the air pressure

at sea level. At heights above 1000 m /3300 feet it may be neces-

sary to replace the carburetor nozzles.

Adjust the carburettor using the screwdriver (7, which has a blade

width of 4 mm).

Before undertaking the adjustment, run the engine for 3 – 5 minutes to warm it up, but

not at high speed!

Set idle speed

Turning the adjusting screw (11) in (clockwise): increases the idle speed.

Turning it out (counterclockwise): lowers the idle speed.

Caution: In no case should the chain move.
