PRESENTATION Dear customer! Customer responsibilities Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the water-powered plant.
PRESENTATION Steps before using a new lawn mower • Please read the operator’s manual carefully. • Check that the cutting equipment is correctly fitted and adjusted. See instructions under the heading Assembly. • Fill with fuel and oil in the engine. A container with sufficient oil quantity is supplied with the machine. See the instructions under the heading fuel handling. ! WARNING! Under no circumstances may the design of the machine be modified without the permission of the manufacturer.
