Poor cut surface
Parallelism a =
0.02/63
a) Large run out of saw
blade. (Large run out
results in poor cut
grain.)
(Dummy disc)
• Same as item No. 1, (b).
b) Poor parallelism of
washer (A) due to
dents or flaws.
Washer (A)
(Fig. 42)
• Remove dents or flaws on
Washer (A) [75], or replace.
c) Cutting speed too fast.
------
• Slow down the cutting speed.
d) During cutting, the
material becomes
rough because of its
curvature, bend, etc.
------
• Eliminate the curvature, bend,
etc. in the material by planing.
a) Cutting speed too fast.
---
• Slow down the cutting speed.
b) Thin extension cord.
------
The usable extension cords are
as follows:
c) Excessive force is
applied because of a
dull saw blade.
------
• Shapen the Saw Blade [704].
• Replace the Saw Blade [704].
d) Wrong selection of
saw blade.
------
• Use a genuine Hitachi saw
blade.
• The higher the number of teeth
of a saw blade, the more
cutting resistance increases.
Where a saw blade with many
teeth is used, cut slowly.
e) During cutting, the
material binds the saw
blade because of a
deformation such as
curvature and bend.
---
• Eliminate the curvature, bend,
etc. in the material by planing.
