9. Notes on working with the
machine
9.1 General
Risk of injury!
Untangle any knots in the cable
10
immediately.
Guide the electric cable behind you
when mowing. Electric cables can
be inadvertently cut when mowing
and present a tripping hazard. They
therefore involve a high accident
risk. For this reason, mow so that
the electric cable is always visible
in the area of grass that has already
been cut.
To ensure a perfect, thick lawn, mow
regularly and keep the grass short.
Do not cut the lawn too short in hot, dry
conditions as it will dry out or burn in the
sun and become unsightly.
The cutting pattern will be better with a
sharp blade than with a blunt one; the
blade should therefore be sharpened
regularly (VIKING specialist dealer).
