- Always wear protective
gloves when handling the blades.
1. To remove a blade (1), grasp it firmly and undo
the central screw (2).
To assemble a blade, tighten the screws (2) with
a torque wrench set to 47-52 Nm.
- Always wear protective gloves when handling the blades and protect
eyes when sharpening.
A badly sharpened blade causes grass to become yellow; if not balanced, excessive vibra-
tion can be caused during cutting.
1. Always sharpen both cutting edges of the blade
(1) using a medium grade grinder. Sharpening
must only be done from the rounded side, as
shown in the illustration, removing as little ma-
terial as possible.
The blade is to be replaced when
the cutting edge has worn down to 10 mm.
Carefully check the blades (1) for breakages, de-
formations or cracks on both the blade and the
fins.
- Impaired blades must al-
ways be replaced and never repaired or
straightened; to do so would cause damage
or injury in the event of breakage during use.
