Selection Of Blades - Hitachi Koki CR13VC Handling Instructions Manual

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 saber
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
