Adjustment Of Components; Bevel Angle Adjustment; Looseness Adjustment Of The Slide Section - Hitachi C 10FSB Technical Data And Service Manual

9. ADJUSTMENT OF COMPONENTS

9-1. Bevel Angle Adjustment

Before shipping from the factory, the height of 8-mm bolts (A),
(B) and (C) is adjusted so that the saw blade section (head) will
stop at 0˚ (right angle), 45˚ to the left, and 45˚ to the right. To
change the head stop positions, instruct the customer to adjust
the height of 8-mm bolts (A), (B) and (C) by turning them. For
example, to change the 45˚ to the right stopper, pull the fixing
pin in the direction indicated by the arrow in Fig. 50-1, and tilt
the head to the right. When setting the head to 0˚ position, be
sure to replace the fixing pin (insert it in the opposite direction
from that indicated by the arrow in Fig. 50-1).
[CAUTION]
If there is any clearance between the tip of 8-mm bolt (A)
(stopper for 0˚) and the fixing pin, the angle of the saw
blade relative to the upper surface of the turn table may
not be an exact right angle. (8-mm bolts (A), (B) and (C)
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 the fixing pin and 8-mm
bolt (A).

9-2. Looseness Adjustment of the Slide Section

After extended use, there may be some looseness between slide pipe (A) and holder (A) because of worn
bushings (slide bearings made of resin) on slide pipe (A) portion. If abnormal looseness is noted, perform
adjustment as described below. (See Figs. 51 and 52.)
(1) Loosen the two 8-mm nuts and loosen each of the two 8-mm hexagon socket set screws (
51 and 52). This will free slide pipe (A) so that it comes to rest on the lower surface of holder (A) hole [31 mm
(1-7/32") dia.].
(2) Gently tighten the 8-mm hexagon socket set
screw until it lightly contacts slide pipe (A),

then turn it two-fifths of a turn and lock it in
position by tightening the 8-mm lock nut.
(This positions slide pipe (A) in the center of
the hole.)
(3) Next, tighten and adjust the 8-mm hexagon
socket set screw

slide smoothly, and lock it in position with the
8-mm lock nut. (The pressing force required
for sliding should be within 2 to 3 kg.)
