Selection Of Blades - Hitachi CR13V2 Handling Instructions Manual

4. Plunge cutting
With this tool, you can perform plunge cutting on
plywood panels and thin board materials. You can
carry out pocket cutting quite easily with the saw blade
installed in reverse as illustrated in Fig. 22, Fig. 24, and
Fig. 26. Use the saw blade that is as short and thick as
possible. We recommend for this purpose that you use
BI-METAL Blade No. 132 mentioned in Table 2. Be sure
to use caution during the cutting operation and observe
the following procedures.
(1) Press the lower part (or the upper part) of the base
against the material. Pull the switch trigger while
keeping the tip of the saw blade apart from the material.
(Fig. 21, Fig. 22)
(2) Raise the handle slowly and cut in with the saw blade
little by little. (Fig. 23, Fig. 24)
(3) Hold the body fi rmly until the saw blade completely cuts
into the material. (Fig. 25, Fig. 26)
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 fi rmly. 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 effi ciency 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.
