5.3 Replace the blades

WARNING: Use blades and screws of
the right type. Husqvarna can only
guarantee safety when using original
blades. Only replacing the blades and
reusing the screw can result in a screw
wearing during mowing. The blades
can then be propelled from under the
body and cause serious injury.
Replace worn or damaged parts for safety
reasons. Even if the blades are intact, they
should be replaced on a regular basis for the best
mowing result and low energy usage. All 3 blades
and screws must be replaced at the same time to
obtain a balanced cutting system. Use
Husqvarna original blades embossed with the
crowned H-mark logotype, refer to
on page 55 .
