19. Changing the oil
The oil must be replaced every 50 operating hours
whilst the engine is off and in warm condition. To do
so, it may be necessary to let the engine run briefly.
Place a suitable collection bucket with min. 1 litre vol-
ume under the oil drain screw (A).
First open the oil drain screw (A) and then the oil fill-
ing nozzle (B) and drain off all the engine oil using a
suitable hose or pipe.
Close the oil drain screw (A) again and fill 0.6 litres of
fresh engine oil into the oil filling nozzle (B).
Then check the oil level using the oil dipstick (B) and
correct the oil level if necessary.
Dispose of oil as per local regulations.
B
Recommended engine oil
SAE 10W-30 or 10W-40 (depending on the operating
temperature).

20. Saw blade replacement
1
Wait until stationary and allow to cool down. Pull
out the mains plug or disconnect the spark plug
connector!
Observe the max. speed specified on the saw blade
and select a saw blade suitable for your machine.
• The saw blade can only be replaced in the firewood
cutting position.
• Loosen the top and bottom screws on the protec-
tive cover approx. 5 mm and open the protective
cover.
• To lock the saw blade into place, insert the locking
pin (1) through the corresponding opening on the
saw blade guard. To do this, insert the pin com-
pletely and straight into the hole. Use the corre-
sponding hole (depending on the saw blade type)
so that the pin is at the lowest point (bottom of the
tooth).
• Loosen the saw blade with the supplied open-end
spanner.
• Remove saw blade flange and saw blade.
• Clean the clamping surfaces. The clamping surfac-
es must be free of dirt, grease, oil and water.
• Insert the new saw blade.
• Mount the saw blade flange again and tighten the
clamp screw with 90Nm. Use the open-ended
spanner supplied. Do not extend the spanner with
a tube or similar and do not tighten the screw by
hitting the open-ended spanner with a hammer.
• Remove the locking pin.
m Attention! When inserting the saw blade, make
sure the running direction is correct!
