Checking The Blades; Removing The Bioclip Plug - Husqvarna PF 21 Operator's Manual

Checking the blades

To achieve the best mowing results it is important that the
blades are undamaged and well-sharpened.
Check that the blades' attachment screws are tight.
IMPORTANT INFORMATION Replacing or sharpening the
blades should be conducted by an authorised service
workshop.
The blades should be balanced after sharpening.
Damaged blades should be replaced when hitting obstacles
that result in a breakdown. Let the servicing dealer judge
whether the blade can be repaired/ground or must be
discarded.
