10. Slowly lower the blade by moving the Raise/Lower Switch forward. For
more details on controlling the lowering speed see section Hydraulic
System (page xx). Do not force the blade in to the cut!! Step Cutting
provides the best performance (fastest cut and longest blade life) for
additional information see section E. Cutting Techniques (page 22).
Never saw deeper than 4” per pass as deeper passes will shorten the
blade life and places higher stresses on the saw. Never twist, rotate, or
bend the blade while in the cut. Do not attempt to cut in a circle or arc as
the blade may be damaged.
