CAUTION: The saw blade guard and spreader assembly
must be aligned properly to the saw blade in
order to prevent kickback.
Mount the saw blade guard assembly, which includes the
spreader and anti-kickback pawls (see Fig. 10-d).
(1) Mounting the spreader
1 Loosen the saw blade tilt lock handle, move the saw blade
tilting mechanism to the left and set the saw blade to 0˚ by
means of the stopper. Tighten the saw blade tilt lock
handle to lock it in position.
2 Turn the wheel fully clockwise and set the saw blade to the
maximum cutting height (see Fig. 10-a).
3 Put a 6 mm spring washer and a D13 flat washer on to the
6 x 90 mm and 6 x 110 mm bolts.
4 Tentatively fasten the spreader on the rear section of the
body using the cushion and two 6 mm bolts mentioned
above (see Fig. 10-b and Fig. 10-d). (The guard bracket
must be attached to the spreader in advance.)
(2) Adjusting the spreader
1 Use a straight-edge to align the spreader with the saw
blade (see Fig. 10-c).
Tighten the two 6 x 16 mm bolts (see Fig. 10-d) with a
wrench to lock the spreader.
2 Check clearance between saw blade tip and the spreader.
It should be less than 1/2" (12.7 mm) at all positions. If not,
loosen the two 6 x 16 mm bolts securing the spreader to
the guard bracket with a wrench and move the spreader up
and down. After adjustment of the spreader is complete,
firmly retighten the two 6 x 16 mm bolts with a wrench (see
Fig. 10-d).
