CHAIN: Check tension regularly. A new chain will require more frequent adjustment. Loosen retention nuts. adjust chain (see assembly instructions). Tighten retention nuts.

1 BAR

-Clean the bar groove (K) and check the lubrication holes (L) in the bar to ensure that they are not clogged.

-Grease sprocket periodically. Rotate sprocket and repeat.

-Rotate bar periodically to maximise bar life.

2 AIR FILTER

-A dust clogged air filter may cause carburetor problems. This may prevent the engine from reaching its maximum r.p.m. and cause high fuel consumption.

-Remove cover.

-Wash filter in petrol (do not use fuel which is mixed with oil).

-The filter can also be cleaned with compressed air.

-Replace filter if damaged or if it does not seal tightly in the air box.

3 SPARK PLUG

Remove and clean the spark plug every 30 hours. Check the electrode gap (0,5/0,6 mm).

-Replace spark plug about every 100 working hours or whenever it is extremely encrusted.

-Heavily encrusted electrodes can result from an incorrect carburetor setting or from wrong fuel mixture (too much oil in the fuel mix) or a poor quality of oil in the fuel mix. Check and correct.

4OIL FILTER

The oil filter is end of the oil suction hose inside the oil tank .To clean and replace the filter pull it out through the oil tank filter opening. Use a piece of bent wire or long forceps. To remove deposits from the oil tank half fill it with kerosene or petrol and shake thoroughly. Drain off and fill the tank with fresh saw chain oil. Never use waste oil.

5FUEL FILTER

To change fuel filter remove the tank cap and pull out the filter with a piece of bent wire or long forceps. Replace the filter as shown in the illustration and reposition it.

It is recommended to replace the fuel filter at least once a year.

CHAIN BRAKE

WARNING: Contact your service dealer if anything appears wrong with your chain brake. Do not disassemble or manipulate the mechanism of the chain brake.

-Clean the brake mechanism periodically (without disassembling it) and control the wear of the band visually.

PERIODICALLY: It is important to clean the saw thoroughly particularly around cylinder fins to avoid overheating of the engine.

LONG STORAGE: Empty fuel and run engine until dry.

ICHAIN BRAKE

TESTING

Your chainsaw is fitted with an automatic safety chainbrake designed to stop the chain in milliseconds in case of kickback. Always hold the saw firmly in both hands.

The chain brake does not provide total protection if the machine is used without taking the necessary precautions or carrying out proper maintenance. The chain brake can also be engaged manually by pushing the chain brake lever forwards.The manual use of the chain brake is recommended only at idle.

Always test the chain brake before using your saw. Do this at idle by engaging the brake (see below).

Always release the brake before starting. Kickback may occur if the end of the bar (see illustrated angle) touches any solid object or if the top of the bar becomes pinched in the wood. Never attempt to start a cut with the end of the bar.

Kickback is a violent upward or rearward movement of the bar and may cause you to lose control of the machine.

Always keep a firm grip on the saw with both hands because,in case of kickback, it is the contact of the left hand with the brake lever which will help to engage the brake.

CAUTION: Initial contact with the wood may occasionally cause the chain to buck, and if the chain teeth are not correctly sharpened, the chain may skate on the wood.

TESTING THE CHAIN BRAKE :

1The chain brake is disengaged when brake lever is pulled back and locked (chain can move).

2The chain brake is engaged when brake lever is in forward position (chain is stopped).
