cover before inserting the saw blade. If the blade clamp
lever is in fixed position, rotate the blade clamp lever in
the direction of the arrow so that it can be locked at the
released position . (Fig. 4)
Insert the saw blade into the blade clamp as far as it will
go. The blade clamp lever rotates and the saw blade is
fixed. Make sure that the saw blade cannot be extracted
even though you try to pull it out. (Fig. 5)
NOTE:
• If you do not insert the saw blade deep enough, the
saw blade may be ejected unexpectedly during opera-

OPERATION (Fig. 7)
CAUTION:
• Always press the shoe firmly against the workpiece
during operation. If the shoe is removed or held away
from the workpiece during operation, strong vibration
and/or twisting will be produced, causing the blade to
snap dangerously.
• Always wear gloves to protect your hands from hot fly-

• Be sure to always wear suitable eye protection which
conforms with current national standards.
• Always use a suitable coolant (cutting oil) when cutting

Press the shoe firmly against the workpiece. Do not allow
the tool to bounce. Bring the blade into light contact with
