INTRODUCTION
The 50 Handheld is intended primarily for nish cuts, scoring and decorative applications, and is
designed for ease of use and convenience. It is not intended for metal or wood cutting. Much like the entire
line of Husqvarna Soff-Cut saws, the handheld saw works in conjunction with the Husqvarna Excel Series
diamond blades and patented skid plates to allow for Ultra Early Entry cutting, which minimizes chipping
and spalling while getting the job done the same day. The patented Soff-Cut Ultra Early Entry dry cutting
system controls random cracking of concrete through the early timing of the saw cutting usually within one
to two hours after the nishing process is complete. The low dust blade guard system with integrated dust
extraction port allows the saw to cut dry and it controls the debris for little or no clean up when used with a
vacuum system.
