a Inaccurate

squareness between

the turn table and the

of the saw blade

(Excessive vibration)

c Inaccurate

squareness between

the fence (A), fence

(B) and the saw blade

d Inaccurate surface

flatness of the fence

(A) and fence (B)

causes workpiece to

move irregularly,

causing poor

squareness of cut

surface.

e Loose fitting of

swiveling portion of

the hinge and the

gear case or sluggish

movement. As a

result, components

may be deformed

because of unstable

gear case or because

the operator applies

excessive pressure

during operation.

f The workpiece moves

during cutting

because it is bent or

deformed.

• Check the fitting surfaces of

the Hinge Ass'y [43], Gear

Case [246] and Shaft (B)

[168] for any foreign

substances (such as cutting

dust), and remove it as

necessary.

• Correct bend, flex or other

deformation by planing and

try cutting.
