ADJUSTING SAW TRAVEL SQUARE
WITH FENCE
The 12” Radial Arm Saw is equipped with 90° and
45° positive miter stops. This feature makes it possible to
produce accurate miter cuts and square cross-cuts at all
times.
To do accurate work, the saw blade travel must be 90°
to the fence. If saw blade travel is not 90° to the fence,
this means that the track arm is not properly aligned.
To check and adjust, proceed as follows:
1. DISCONNECT MACHINE FROM
POWER SOURCE.
2. Remove blade guard assembly and saw blade from
the cuttinghead assembly (A) Fig. 50, and insert wrench
(B) between arbor flanges in place of blade as shown.
Tighten arbor nut.
3. Place a steel square (C) Fig. 50, against fence as
shown, and lower cuttinghead assembly (A) so that
wrench (B) just clears the table top.
4. Pull cuttinghead assembly (A) Fig. 50, along square
(C). If wrench (B) does not travel parallel to the square
(C), the following adjustment is necessary.
5. Remove three screws (D) Fig. 51, and remove miter
scale (E).
6. Loosen three screws (F) Fig. 52, and loosen track
arm clamp handle (G).
7. To move front end of track arm to the right, loosen
set screw (H) Fig. 53, and tighten set screw (J). To move
front end of track arm to the left, loosen set screw (J) and
tighten set screw (H).
8. When the cuttinghead travels parallel to the square,
tighten three screws (F) Fig. 52. Replace miter scale (E)
Fig. 51, and replace and tighten three screws (D). Make
certain the zero graduation mark on the scale (E) lines up
with the pointer (K).
9. Replace blade and blade guard assembly.
