Starting And Stopping; Check Before Starting - Husqvarna 555FX Operator's Manual

Check before starting

• Check the blade to ensure that no cracks have formed
at the bottom of the teeth or by the centre hole. The
most common reason why cracks are formed is that
sharp corners have been formed at the bottom of the
teeth while sharpening or that the blade has been
used with dull teeth. Discard a blade if cracks are
found.
• Check that the support flange is not cracked due to
fatigue or due to being tightened too much. Discard
the support flange if it is cracked.
• Ensure the locking nut has not lost its captive force.
The nut lock should have a locking force of at least 1.5
Nm. The tightening torque of the locking nut should be
35-50 Nm.
• Check that the blade guard is not damaged or
cracked. Replace the blade guard if it is exposed to
impact or is cracked.
Check that the trimmer head and trimmer guard are not
damaged or cracked. Replace the trimmer head or
trimmer guard if they have been exposed to impact or are
cracked.
• Never use the machine without a guard nor with a
defective guard.
• All covers must be correctly fitted and undamaged
before you start the machine.
