Checking / Replacing blades

17.3.1 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.

17.3.2 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.

For the assembly/disassembly of the blade you need a torque wrench. After
assembly, check that the blade screws are firmly tightened. Always wear
protective gloves when working on the blade.
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
filler cap/dipstick.
3. Place a suitable container next to the mower to
collect the waste oil and then tilt the mower to the
right side. The waste oil will drain through the filler
neck. Allow the oil to drain off completely.
4. Fill in the recommended oil. Do not overfill! Wait a
few minutes for the oil to settle in the engine before
measuring the oil level.
