90° AND 45° BEVEL POSITIVE STOPS
The saw is equipped with adjustable positive stops at both 90° (A) Fig. 6,
and 45° (B) Fig. 6. It is recommended that the accuracy of these stops be
checked periodically and adjustments be made as necessary. These
procedures are explained fully in the following sections of this manual.
BACK CUTS
This saw can be adjusted for bevel cuts of up to 3° beyond the positive stop
at either the 45° or the 90° position. In normal operation the bevel stop
sleeve (C) Fig. 6, is aligned as shown in Fig. 6. To adjust the saw for a bevel
cut beyond the normal 45° to 90° range:
1.
2. Set saw for either a 45° or a 90° bevel cut.
3. Loosen bevel adjustment knob approximately two turns.
4. Pull out on the bevel stop sleeve (C) Fig. 6. Rotate sleeve to the position
shown in Fig. 6A and push sleeve back in.
The saw can now be adjusted for a bevel cut between the normal stop (45°
or 90°) and 3° beyond the normal stop.
5. Position saw to desired angle and firmly tighten bevel adjustment knob.
NOTE: The bevel stop sleeve must be returned to the normal
position (see Fig. 6), before the saw can be adjusted for a bevel cut
of between 45° and 90°.
