Risk of injury!
Stop the engine and wear protective
gloves whenever working on the guide
bar and on the saw chain.
Loosen the retaining nut (55) by max. 1 turn.
Slightly lift the guide bar tip and turn the chain
stretching screw (57) clockwisely until the correct chain
tension is reached.
saw chain is correctly stretched when it can be
The
lifted in the centre of the chain guide by appr. 3 – 4 mm.
Turn the chain stretching screw anti-clockwise when the
saw chain is stretched too much.
Check that the chain links are positioned correctly in
the guiding groove of the guide bar.
Re-tighten the locking nut (55).
Check the saw chain tension
before start of work
after the first steps
during sawing regularly all 10 minutes
Only with a correct clamped saw chain and a sufficient
lubrication you can influence the durability.
Pay attention to the following:
a new saw chain must be restretched more frequently.
in case of heating of chain to operating temperature it
expands and needs to be reclamped.
After finishing the sawing works release tension of saw
chain as in case of cooling too high tensions would emerge
in the saw chain.
if chain flackers or comes out of the guide clamp it again
immediately.

Fuelling
Utmost care is required when handling fuel and
oil. Keep away smoke and open flames (risk of
explosion).
This product is operated by a mixture from regular
gasoline (unleaded) and two-stroke engine oil.
Petrol: Octane number at least 91 ROZ unleaded
• Do not fill in leaded gasoline, diesel or other non-approved
fuels.
• Do not use gasoline having a smaller octance number than
91 ROZ. This may lead to severe engine damages due to
increased engine temperatures.
• If you frequently operate the product at high speeds, you
should use gasoline with a higher octane number.
The use of unleaded gasoline is recommended for
environment protection reasons.

Two-stroke engine oil:
acc. to JASO FC or ISO EGD specifications
• Do only use two-stroke engine oil for air-cooled engines.
Ratio of mixture 40:1
Gasoline
1 litres
2 litres
5 litres
10 litres
• Measure the oil quantity accurately as a small deviation of it
has a large effect on the ratio of mixture in particular for small
fuel quantities.
• Do not change the ratio of mixture. This will lead to more
residues of combustion, a higher fuel consumption, a
decrease of output or damages to the engine.
Mix petrol and oil in the supplied fuel mixing can (27).
• Fuels have only a limited shelf-life. Outdated fuels and fuel
mixtures may result in starting problems. Therefore, mix only
that quantity of fuel which you can use within a month.
• Only store fuels in containers approved and identified for this.
Keep fuel containers in a dry and safe area.
• Make sure that fuel containers are kept out of the reach for
children.
Make sure to dispose of fuel remainders and liquids used
for cleaning according to relevant regulations and in an
environmentally compatible manner.

• Stop the engine and allow it to cool down.
• Wear protective gloves.
• Avoid eye and skin contact.
• Strictly follow the instructions under "Safe
handling with fuels".
Clean the area around the filler neck. Contamination in the
tank may result in malfunction.
Carefully open the tank cap (19) to allow possible
overpressure to relax.
Shake the container once more before pouring the fuel
mixture into the tank.
Carefully fill the fuel mixture up to the lower edge of the filler
neck. Avoid spilling of fuel or oil. Clean the device
immediately when you have spilled fuel or oil.
Make sure that no fuel can come into the soil.
Carefully close the tank cap after fuelling and check that it
does not get loose during operation.
Check that there is no leakage on the tank cap and fuel lines.
If there are leaks this product may not be started.
Clean the tank cap and the area around it.
Go away at least three metres from the fuelling place to
start the chain saw.
