CAUTION
Avoid plunge cutting for metallic materials. This can
easily damage the blade.
Never pull the switch trigger while the tip of the
saw blade tip is pressed against the material. If you
do so, the blade can easily be damaged when it
collides with the material.
Make absolutely sure that you cut slowly while
holding the body firmly. If you apply any
unreasonable force to the saw blade during the
cutting operation, the blade can easily be damaged.

SELECTION OF BLADES

To ensure maximum operating efficiency and results, it
is very important to select the appropriate blade best
suited to the type and thickness of the material to be cut.
NOTE:
Dimensions of the workpiece mentioned in the table
represent the dimensions when the mounting
position of the base is set nearest to the body of
the reciprocating saw. Caution must be exercised
since dimensions of the workpiece will become
smaller if the base is mounted far away from the
body of the reciprocating saw.
1. Selection of HCS blades
The blade number of HCS blades in Table 1 is
engraved in the vicinity of the mounting position
of each blade. Select appropriate blades by referring
to Tables 1 and 3 below.
