Changing the engine oil
N O T I C E
Engine oil is toxic and must not be released into the environment. When
changing, use suitable collecting containers with sufficient volume!
Observe the manufacturer's instructions and, if necessary, contact your
local authorities for further information regarding proper disposal.
Change engine oil:
1. drain the used oil while the engine is warm. Warm oil drains quickly and
completely.
2. wipe the oil filling area clean and then remove the oil drain screw.
3. Fill with the recommended oil. Do not overfill! Wait a few minutes for the oil
to settle in the engine and only then measure the oil level.

Blade checking / changing
NOTICE
After assembly, check that the blade screws are firmly tightened. Always wear
protective gloves when working on the blade.
18.3.1
Checking the blade
1.
Tilt the mower to the right with the air filter side facing up. This helps to avoid fuel leaks
and hard starting.
2.
Check the blade for damage, cracks and excessive rust or corrosion: a blunt blade can be
sharpened, but a blade that is excessively worn, bent, cracked or otherwise damaged
must be replaced.
18.3.2
Replacing the blade
1.
Remove the screw with a socket wrench. Use a wooden block to prevent the blade from
turning when the bolt is removed. Then remove the blade.
2.
Mount the blade with the screw and special washers. Be sure to mount the special
washers with the concave side facing the blade and the convex side facing the bolt.
3.
Tighten the screw with a torque wrench. Use a wooden block to prevent the blade from
turning when the screw is tightened.
