9. ADJUSTMENT OF COMPONENTS
9-1. Bevel Angle Adjustment
Before the power tool is shipping from the factory, the height of 8 mm bolt (A), 8 mm bolt (B) and 8 mm set screw
is adjusted so that the saw blade section (head) will stop at 0û (right angle), 45û to the left, and 45û to the right.
To change the head stop positions, instruct the customer to adjust the height of 8 mm bolt (A), 8 mm bolt (B) and 8
mm set screw by turning them. For example, to change the 45û to the right stopper, pull set pin (A) in the direction
indicated by the arrow in Fig. 51-b, and tilt the head to the right. When setting the head to 0û position, be sure to
replace set pin (A) (insert it in the opposite direction from that indicated by the arrow in Fig. 51-b).

9-2. Ball Bushing (Linear Bearing)
(1) Structure of the ball bushing
The ball bushing is commonly called a linear
ball bearing. Inside the bearing is elongated
guide grooves in which steel balls circulate
and roll when a load is applied. (as indicated
by the arrow marks in Fig. 52). This type of
device is widely used in automated machine
tools. The advantage of the ball bushing is
that its friction coefficient remains largely
unchanged even when the load is increased,
ensuring smooth sliding movement.
Fig. 52
CAUTION: If there is any clearance between the tip of 8 mm set screw (stopper for 0û) and set pin (A),
the angle of the saw blade relative to the upper surface of the turn table may not be an
exact right angle. (8 mm bolt (A), 8 mm bolt (B) and 8 mm set screw are located at the rear
of the turn table.) Press down on holder (A) and lock it in position with the clamp lever so
that there is no clearance between set pin (A) and the 8 mm set screw.
In addition, slide pipe (B), made of bearing steel and heat treated to a high degree of hardness (HRC 62 to
65), is highly resistant to wear.
Sales persons should have a good understanding of the structure and rugged characteristics of this
exceptional mechanism to enhance sales promotion.
