Always carry out checks before use and with the en-
gine switched off.
1. Before tensioning, loosen the fixing nuts (16) a lit-
tle with the spark plug wrench (20).
2. Turn the chain tensioning screw (23) clockwise
with the slotted screwdriver (20) to increase the
tension.
3. Tighten the fixing nuts (16) with the spark plug
wrench (20).
4. The saw chain (1) must be in contact with the un-
derside of the saw bar. Check whether the saw
chain (1) can be pulled over the guide rail (2) by
hand (with the chain brake released, pull the front
hand guard (3) back).
NOTE
A new saw chain (1) stretches and needs to be re-ten-
sioned more often.
9.3 Mixing fuel
The engine must be operated with a fuel mixture of
petrol and engine oil.
m WARNING
Avoid direct skin contact with fuel and inhalation of
fuel vapours.
Use only a mixture of unleaded petrol (min. RON 95)
and special 2-stroke engine oil (JASO FD/ISO - L -
EGD). Mix the fuel mixture as per the fuel mixing ta-
ble.
Put the correct amount of petrol and 2-stroke oil into
the enclosed mixing bottle (22) (see "Fuel mixing ta-
ble"). Then shake the mixing container (22) well.
9.3.1 Fuel mixing table
Mixing process: 40 parts petrol to 1 part oil
Petrol ...................................................... 2-stroke oil
0.5 litres ......................................................... 12.5 ml
9.4 Filling in fuel (Fig. 8)
m WARNING
Only fill the fuel when the engine is switched off and
has cooled down. There is a danger of fire!
1. Always clean the area around the fuel tank cap
(13) before filling to prevent dirt from falling into
the fuel tank. Use a dry, lint-free cloth for this pur-
pose.
2. Lay the device on its side with the fuel tank cap
(13) facing upwards.
3. Turn the fuel tank cap (13) anti-clockwise and
open it. The fuel tank cap (13) is connected to an
anti-loss device in the fuel tank and thus cannot
fall off.
4. Pour the fuel mixture into the fuel tank. Do not spill
fuel when refuelling and do not fill the fuel tank to
the brim.
5. Wipe up spilled fuel immediately.
6. Turn the fuel tank cap (13) clockwise to close it.
NOTE
Also check the chain oil after each fuel fill.
9.5 Drain the fuel
Only empty the fuel tank outdoors or in well-ven-
tilated rooms. Make sure that no fuel gets into
the soil (environmental protection). Use a suita-
ble base.
1. Hold a collection container under the fuel tank.
2. Unscrew and remove the fuel tank cap (13) of the
fuel tank.
3. Drain the petrol/oil mixture completely.
4. Screw the fuel tank cap (13) back on by hand.
9.6 Fill in chain oil (Fig. 8)
m WARNING
Only fill the saw chain oil when the engine is switched
off and has cooled down. There is a danger of fire!
Never work without chain lubrication! If the saw chain
(1) runs dry, the cutting gear will be irreparably de-
stroyed in a short time.
Always check chain lubrication before working.
NOTE
Use only saw chain oil. Preferably biodegradable. Do
not use waste oil, engine oil, etc.
Check during work that the chain lubrication is work-
ing.
1. Always clean the area around the chain oil fuel
cap (11) before filling so that no dirt falls into the
chain oil tank. Use a dry, lint-free cloth for this pur-
pose.
2. Lay the device on its side with the chain oil fuel
cap (11) is facing upwards.
3. Turn the chain oil fuel cap (11) anti-clockwise and
open it. The chain oil fuel cap (11) is connected to
an anti-loss device in the chain oil tank and thus
cannot fall off.
4. Pour the bio chain oil into the chain oil tank. Do
not spill chain oil when refuelling and do not fill the
chain oil tank to the brim.
5. Wipe up spilled chain oil immediately.
6. Turn the chain oil fuel cap (11) clockwise to close
it.
