Hitachi CR 13VBY Technical Data And Service Manual page 8

Do not use any saw blade with a worn-out blade hole
The saw blade may come off if the blade hole is worn out. Replace such saw blade with new one. If the
new saw blade comes off even after replacement, the holder pin may be worn out. Replace the holder pin
with new one.
(5) Saw blade can be mounted in either direction, upward or downward
The Model CR 13VBY is convenient for cutting materials on the floor or near the wall, and also for plunge
cutting on plywood panels because the saw blade can be mounted in reverse.

(6) Swing cut mechanism
Cutting operation is selectable between smooth "straight cut mode" and efficient "swing cut mode" by
switching the change lever. When the swing cut mode is selected, the rear of the plunger (reciprocating shaft)
moves up and down along the slope of the counter weight in the gear case through the swing roller to
powerfully cut into a workpiece. The amount of rebound is less than the conventional orbital cutting, and soft
wood workpieces can be cut efficiently in this mode. Moreover, the swing cut mode is selectable even if the
saw blade is mounted in reverse. This is an innovative cutting mechanism. (Note that the swing cut mode is
not selectable if the saw blade is mounted in reverse for the Model CR 13VBY shipped to the U.S.A. and
Canada.)
