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 Cordless 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 Cordless Reciprocating Saw.
1. Selection of HCS blades
The blade number of HCS blades in Table 4 is
engraved in the vicinity of the mounting position
of each blade. Select appropriate blades by referring
to Tables 4 and 6 below.
