6.1 Introduction - maintenance

WARNING:
switched off before any maintenance is
done.
WARNING:
For better operation and longer service life, make sure
to clean the product regularly and replace worn parts.
All maintenance and servicing must be done according
to Husqvarna's instructions. Refer to
55 .
When the product is first used, the blade disc and
blades should be inspected once a week. If the amount
of wear during this period has been low, the inspection
interval can be increased.
It is important that the blade disc rotates easily. The
edges of the blades should not be damaged. The
lifetime of the blades varies immensely and depends for
instance on:
• Operating time and size of the work area.
• Type of grass and seasonal growth.
• Soil, sand and use of fertilizers.
• The presence of objects such as cones, windfalls,
toys, tools, stones, roots and the like.
The normal life is 3 to 6 weeks when used under
favorable conditions. Refer to
blades on page 37 on how to replace the blades.
Note:
Working with blunt blades gives a poorer
mowing result. The grass is not cut cleanly and more
energy is needed resulting in the product not mowing
such a large area.
