ADJUSTING BLADE GUIDES
1. Disconnect machine from the power source.
2. Loosen bolt (A, Fig. 9) and slide blade guide
assembly (E, Fig. 9), as close as, possible with-
out interference to the material being cut.
Tighten knob.
3. Loosen bolt (C, Fig. 9) and slide blade guide
assembly (D, Fig. 9), as close as, possible with-
out interference to the material being cut.

ADJUSTING BLADE TENSION
1. Disconnect machine from the power source.
2. Open blade cover and observe the position
of the blade on the wheel. If the blade is not
next to the wheel flange, adjust blade track-
ing following the steps under “Adjusting Blade
Tracking”.
3. If the blade is next to the wheel flange,
loosen the blade guide assembly lock knob and
hex head bolt (A & C, Fig.9) and slide the blade
guide assemblies as far apart as possible. Lock
in place.
4. Depress blade. Finger pressure should cause
approximately 0.004” deflection. Turn blade
tension knob (B, Fig.9) until the proper ten-
sion is achieved. Re-position guides for cutting
material.
CHANGING BLADES
1. Disconnect machine from the power source.
2. Raise the saw arm to the vertical position
and lock in place with lock lever.
3. Open blade cover by removing the small
knob found on the top side of the bow.
4. Remove red blade guards by removing two
screws.
WARNING: It is essential these two guards
be installed after the new blade has been fit-
ted. Failure to comply may cause serious injury!
5. Release tension on the blade by turning ten-
sioning bolt (A, Fig.9), and remove the blade.
6. Place new blade be-
tween the blade guide
assemblies and around
each wheel. Make sure
blade teeth are point-
ing in the proper direc-
tion (Figure 10). Ten-
sion enough to hold in
place.
7. Install red blade guards with two screws.
8. Tension blade fully, see “Adjusting Blade
Tension”.
9. Place two to three drops of lightweight oil
on the blade.
10. Connect machine to the power source.
11. Run saw and make sure blade is tracking
properly, see “Adjusting Blade Tracking”. As
a general rule, the thinner the material to be
cut, the more teeth per inch on the blade. A
minimum of three teeth should be in contact
with the material at all times during the cut. If
the teeth straddle the material, severe damage
can result to the material and the blade.
ADJUSTING BLADE GUIDE BEARINGS
1. Disconnect machine
from the power source.
2. Loosen bolt (A, Fig.
11) and adjust assembly
so that back roller bear-
ing is approximately
0.002” - 0.003” from
the back of the blade.
Tighten bolt.
3. Loosen nut (B, Fig. 11) and turn nut (C, Fig.
11) to adjust eccentric bearing to a clearance of
0.001”. Tighten nut (B, Fig. 11) to lock.
4. Connect machine to power source.
ADJUSTING BLADE TRACKING
WARNING: Blade tracking adjustment re-
quires running the saw with the back cover
open. This adjustment must be completed by
qualified persons only. Failure to comply may
cause serious injury.
