• Slide the slotted hole of the guide rail (16) over the
two protruding pins.
• Place the saw chain (17) over the teeth of the chain
wheel (26). Insert the saw chain (17) accurately in
the direction indicated on the guide rail (16). In the
tip of the guide rail (16) there is a guide wheel into
whose teeth the saw chain (17) must be inserted.
• Pull slightly on the guide rail (16) to slightly pre-ten-
sion the saw chain (17).
• Fit the chain cover (22) back on. Make sure that
the internal chain tensioning pin (23) fits into the
matching hole (25) in the guide rail (16) (see Fig.
S). If necessary, adjust the chain tensioning screw
(21) with the spark plug wrench / slotted screwdriv-
er (31) (see Fig. T).
• Screw on the two fastening nuts (20) by hand. How-
ever, make sure that you do not tighten them yet.
• Use the spark plug wrench / slotted screwdriver
(31) to turn the chain tensioning screw (21) clock-
wise until the lower part of the saw chain (17) slides
into the guide rail (16). The saw chain (17) must be
in contact with the underside of the bar. When the
chain brake is released, it must be possible to pull
the saw chain (17) over the guide rail (16) by hand
(see Fig. U).
Note
A new saw chain (17) stretches and needs to be
re-tensioned more often.
• Tighten the two fixing nuts (20) with the spark plug
wrench / slotted screwdriver (31).
8.2 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 (30) (see "Fuel mixing ta-
ble"). Then shake the mixing container (30) well.
8.2.1 Fuel mixing table
Mixing process: 40 parts petrol to 1 part oil
Petrol ...................................................... 2-stroke oil
0.5 litres ......................................................... 12.5 ml
8.3 Filling with fuel (Fig. R)
m WARNING
Only fill the fuel when the engine is switched off and
has cooled down. There is a risk of fire!
• 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 purpose.
• Lay the device on its side with the fuel tank cap (13)
facing upwards.
• 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.
• Pour the fuel mixture into the fuel tank. Do not spill
fuel when refuelling and do not fill the fuel tank to
the brim.
• Wipe up spilled fuel immediately.
• Turn the fuel tank cap (13) clockwise to close it.
NOTE
Also check the chain oil after each fuel fill.
8.4 Filling with chain oil (Fig. Q)
m WARNING
Only fill the saw chain oil when the engine is switched
off and has cooled down. There is a risk of fire!
Never work without chain lubrication! If the saw chain
runs dry, the set of blade and saw chain will be irrep-
arably destroyed 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.
• Always clean the area around the chain oil fuel cap
(14) before filling so that no dirt falls into the chain
oil tank. Use a dry, lint-free cloth for this purpose.
• Lay the device on its side with the chain oil fuel cap
(14) is facing upwards.
• Turn the chain oil fuel cap (14) anti-clockwise and
open it. The chain oil fuel cap (14) is connected to
an anti-loss device in the chain oil tank and thus
cannot fall off.
• Pour the provided 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.
• Wipe up spilled chain oil immediately.
• Turn the chain oil fuel cap (14) clockwise to close it.
