causes the saw blade

to cut into the

workpiece at an

angle.

Factory

standard

(Fig. 28)

Replace the Base [74] and/

or Table [60] if deformed.

h Loose fitting of

swiveling portion of

the arm and the

angle regulator or

sluggish movement.

As a result,

components may be

deformed because of

unstable arm or

because the operator

must apply excessive

pressure during

operation.

---

Check the fitting surfaces of

the Arm [120], Angle

Regulator [32] and the

Pivot Shaft [53] for any

foreign substance (such as

cutting dust), and remove it

as necessary.

i Excessively fast

cutting speed causes

deflection of the saw

blade and inaccurate

cutting.

---

Reduce cutting speed.

Appropriately 10 seconds

for a square wood

workpiece of 60 mm

(2-3/8").

j

Excessive cutting

force (pressure) is

required because of

dull saw blade.

---

Sharpen the Saw Blade

[702] again.

k The workpiece

moves during cutting

because it is bent or

deformed.

---

Correct bend, flex or other

deformation by planing and
