WARNING
Disconnect machine from the power source
before adju sting or changi ng vise po sition!
Failure to compl y may cause seri ou s in ju ry!
Adjusting Vise Square to the Blade
Position A
1. Place a machinist' s square on the bed
against the blade and the vise. The square
should lie along the entire length of the vise
and blade without a gap.
2. If adjustm ent is necessary, loosen bolts (A,
Fig. 5) holdi ng the vise and adjust vise so
square lines up properl y . Tighten bolts.
3. You may want to perform a test cut. Cut off
the end of the stock. Make anot her cut so
that you have an accurat e sect ion to
measure. Measure thic k ness wit h c alipers.
Adjusting Vise for Miter Cuts
Position B
1. Move the vi se into the second set of
threaded holes (B, Fig. 5) by removing hex
cap bolts (A, Fig. 5).
2. When angle has been set ti ghten bolts.
3. Adjust other jaw.
4. There is an angle label on the backside of
the bed. This is for ref er enc e only. Chec k
angles with a machi nist’s prot r ac tor.
For your own safety: only use position B for
miter cuts. Vise square to the blade, in position
B would expose more of the blade, ri ght of the
vise, than is necessary for the cut.
Positioning Vise
To position the m ov eable v ise:
1. Pull up on the rack block (C, Fig. 5).
2. Move vise to desired l oc ation by sliding
along bed.
3. Tighten vi se by turning handwheel, found at
the left end of the bed, cloc k wise.
4. Loosen vise by turning handwheel counter-
clockwise so you can pull up on the rack
block.
