INTRODUCTION10 – English 1153136-49 Rev.2 2010-04-08Dear customer!Congratulations on your choice to buy a Husqvarnaproduct! Husqvarna is based on a tradition that datesback to 1689, when the Swedish King Karl XI ordered theconstruction of a factory on the banks of the HuskvarnaRiver, for production of muskets. The location was logical,since water power was harnessed from the HuskvarnaRiver to create the water-powered plant. During over 300years of continuous operation, the Husqvarna factory hasproduced a lot of different products, from wood stoves tomodern kitchen appliances, sewing machines, bicycles,motorcycles etc. In 1956, the first motor driven lawnmowers appeared, followed by chain saws in 1959, and itis within this area Husqvarna is working today.Today Husqvarna is one of the leading manufacturers inthe world of forest and garden products, with quality asour highest priority.
