USING JACKSHAFT WRENCH
Blades can also be installed and removed easily by using the Jackshaft
Wrench.
1. CAUTION: DISCONNECT SAW FROM POWER SOURCE.
2. The depth adjustment should be set at its highest position to allow
maximum blade exposure below the base.
3. Turn the saw over and make sure the handle rests on a rigid support.
See Fig. 3.
4. Retract the blade guard. Insert the jackshaft wrench (A), Fig. 3,
between the blade and guard and onto the flats on the jackshaft flange.
5. While holding the jackshaft wrench (A), the blade retaining bolt can
be tightened or loosened with the blade bolt wrench (C) as shown in
Fig. 3. Turn the blade retaining bolt counterclockwise to loosen and
clockwise to tighten. Tighten blade retaining bolt just enough to prevent
slippage during normal cutting.

WHEN USING ABRASIVE BLADES
Special abrasive blades are available for cutting various materials other
than wood.
When abrasive blades are used, Accessory Catalog No. 48095 “Solid
Lock-Up Screw and Washer”, must be used in place of the regular blade
retaining bolt and outer blade flange. Use the “solid lock-up screw” with
the washer (supplied with 48095 solid lock-up screw), assembled between
the solid lock-up screw head and the blade.
CAUTION: Never use the solid lock-up screw or washer with
wood cutting blades.
