Uncrating and Assembly
1. Finish uncrating the bandsaw. Contact your
distributor if any damage has occurred during
shipping.
2.
Remove any preservative with kerosene or
diesel oil. Do not use gasoline, paint thinner,
or any cellulose-based product. These will
damage painted surfaces.
3. Remove two hex cap screwsfrom left side of
the vertical column. Attach shear assembly
(A) to column by inserting hex cap screws.
Figure 1.
4. Place rip fence onto table and lock.
Installation
1. Remove four nuts and washers holdingthe
bandsawto the shipping crate bottom.
2. Usingthe lifting ring located onthe top of the
saw, lift the bandsawinto it's permanent
location. For best performance, the bandsaw
should be bolted to the floor after a level
position has been found.
3. Using a square, adjust the table 90 degrees to
the blade both front to back and side to side.
Loosenthe hex cap screws belowthe table to
move it andtighten to hold the table in place.
If necessary, adjust the pointers to zero should
they read different oncethe table is
perpendicular to the blade in both directions.
A-
4. To level the machine, place a machinist's level
on the table and observe in both directions.
5. Use metal shims underthe appropriate hold
down screw. Tighten screw and recheck for
leveL
6. Adjust with additional shims, as required, until
the table is level when all mounting screws (or
nuts) aretight.

1. Turn blade tracking knob (A, Fig. 10) clockwise
to track blade toward front of blade wheel.
2. Turn counter-clockwise to track blade toward
rear of blade wheel. Blade should betracked
as close to the center of the top blade wheel as

Blade Guide Adjustment
Lt CAUTION
Blade guides must be properly adjusted or
damage may occur to the blade and/or the
guides.
Lt WARNING
Air nozzle has been removed to show detail.
Always operate saw with the air nozzle in place
and properly adjusted. Failure to comply may
cause serious injury!
1. Loosen lock knob (A, Fig. 9) and turn blade
guide handwheel (B, Fig. 9) until blade guide
assembly is half way betweentable and head,
then tighten lock knob (A, Fig. 9).
2. Loosen screw (A, Fig. 11) andslide blade guide
assembly away from the blade until it stops.

3. Loosenscrew (A, Fig. 12). Slide blade stop (B,
Fig. 12)toward blade until a gap of 1/32"
remains. Tighten screw (A, Fig. 12).
4. Slide blade guide assembly toward blade until
blade guides are behind gullets as in Fig. 13.
Tighten screw (A, Fig. 13)
5. Open the upper access door and rotatethe
blade wheel by hand until the weld portionof
the blade is betweenthe two fingers.
