2. TROUBLESHOOTING GUIDE:
The circled numbers in the descriptions below correspond to the item numbers in the Parts List and exploded
assembly diagram.
Item
Phenomenon
1.
Inaccurate cutting.
(Unable to obtain accurate
perpendicularity of cut
surface.)
(Mitered joints cannot be
accurately aligned.)

Possible Cause (s)
A. Improper perpendicularity
between Vise (B) [82] and the
Base Ass'y [103] causes
inclined bevel cutting, resulting
in inaccurate angles.
B. Improper perpendicularity
between Saw Blade and Turn
Table [87] causes Saw Blade
Perpendicu-
to cut into Workpiece at
larity
Standard:
inclined angle.
0.2/90
C. Excessive deflection of the
Saw Blade.
(Excessive vibration)
D. Turn Table [87] is not
properly fixed with the Side
Handle [116], and moves
during the cutting operation.
E. Surface of Vise (B) uneven
(worn or damaged) and
causes uneven cutting of the
workpiece.
F. Surface of Turn Table [87]
uneven (worn or damaged)
and causes uneven cutting of
the workpiece.
G. Excessive looseness or ex-
cessive tightening of the turn
connection between the Hinge
[119] and Gear Case [53]
which causes either vibration
or irregular movement of the
Saw Blade, and subsequent
uneven cutting.
H. Excessively fast cutting
operation speed causes
deflection of the Saw Blade,
and subsequent uneven
cutting.
I. Excessive pressure is
applied because of a dull Saw
Blade.

(All Dimensions in Millimeters)
Countermeasure (s)
Adjust or replace Vise (B) [82].
•
Adjust M12 Nut [93] and M12
Lock Nut [92] to eliminate gap
and vibration between Hinge
[119] and Gear Case [53].
•
Replace Hinge [119].
(If Hinge damaged or deformed)
•
Replace Gear Case [53].
(If Gear Case damaged or deformed)
•
Replace Turn Table [87].
(If Turn Table damaged or de-
formed)
•
Replace the Saw Blade.
•
Replace Washer (A) [28] and/or
Washer (B) [29].
Securely fix the Turn Table [87]
with the Side Handle [116] and
recheck after next cutting.
Replace Vise (B) [82].
Replace the Turn Table [87].
•
Check for material (chips, dust,
etc.) in the joints of the Hinge
[119], Gear Case [53] and
Hinge Shaft [102], and clean as
necessary.
•
Readjust M12 Nut [93] and M12
Lock Nut [92] to ensure proper
movement of the Gear Case
[53].
•
Reduce cutting operation
speed.
(Appropriate cutting time for a
100 mm (4") workpiece is 10 ---
15 seconds.
•
Use a Tungsten Carbide Tipped
Saw Blade for wood or alumi-
num (Code No. 959024).
•
Resharpen or replace the Saw
Blade.
