The blade guides must be properly adjusted to prevent
the blade from twisting during operation. The upper
blade guides and blade support bearing should be
adjusted only after the blade is tensioned and tracking
properly. To adjust, proceed as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Loosen screw (A) Fig. 21, and remove blade guard
(B) from guide assembly.
2. The upper guide bracket (C) Fig. 22, is assembled to
the lower end of the guide post (D) by screw (E). Loosen
screw (E) and move the guide bracket (C) in or out until
the front edge of the guides (F) are just behind the blade
“gullets” (bottom of saw teeth) while making sure the
guides are flat with the blade then tighten screw (E).
3. The upper blade guides are held in the guide bracket
with set screws (G) Fig. 21. Loosen set screws (G) and
adjust blade guides as close as possible to the sides of
the saw blade being careful not to pinch the saw blade.
Then tighten screws (G).
4. The upper blade support bearing (H) Fig. 21,
prevents the blade from being pushed back too far while
cutting which could damage the set in the saw teeth.
The upper support bearing (H) should be adjusted
approximately 1/64" behind the blade by loosening set
screw (J), moving the support bearing in or out until it is
1/64" behind the back of the blade and tightening set
screw (J).
5. MAKE CERTAIN TO REPLACE BLADE GUARD
THAT WAS REMOVED IN STEP 1.
ADJUSTING LOWER BLADE
GUIDES AND BLADE
SUPPORT BEARING

The lower blade guides and blade support bearing
should be adjusted at the same time as the upper guides
and bearing as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Loosen screw (A) Fig. 23, and move the guide
bracket (B) in or out until the front edge of the guides (C)
are just behind the blade “gullets” (bottom of saw teeth)
while making sure the guides are flat with the blade then
tighten screw (A).
