Maintenance And Inspection - Hitachi CR 24DV Handling Instructions Manual

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 4 is
engraved in the vicinity of the mounting position of
each blade. Select appropriate blades by referring to
Table 4 and 6 below.

MAINTENANCE AND INSPECTION

(mm)
CAUTION
Be sure to turned off the switch and remove the
2.5 – 6
battery before maintenance and inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will result
2.5 – 6
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
2.5 – 6
new one as soon as excessive abrasion is noted.
2. Inspecting the mounting screws:
2.5 – 6
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
2.5 – 6
to do so could result in serious hazard.
