Figure 7-8: blade guide adjustment
3. Place quick tension handle in
tension
position.
4. Loosen two set screws (K, Figure 7-8) with 3mm
hex wrench, and slide entire guide bracket until
front of guide bearings are about 0.015” (1/64”)
behind blade gullet (curved area at base of
tooth). See Figure 7-9.
Figure 7-9: guide bearing position
5. Tighten set screws (K, Figure 7-8).
6. Loosen lock knob (L
1
) for either of the front
guide bearings.
7. The guide bearing rotates on an eccentric shaft.
Adjust guide bearing by rotating knurled knob
(L
2
) until guide bearing is almost touching blade.
Tip:
This blade-to-bearing gap can be quickly
set by inserting a business card, or dollar bill
folded twice (4 thicknesses), between them
then allowing the guide bearing to
lightly
contact
the card/bill.
Do not force guide bearing
against side of blade. Overtightening will
reduce bearing life. Guide bearings should
not rotate when saw is running without a
workpiece; they will generally only make
contact with blade when there is pressure
from the cutting operation.
8. Tighten lock knob (L1).
9. Repeat process for opposite guide bearing.
7.9
Upper thrust bearing
Blade teeth are sharp; use care
when working near saw blade.
Refer to Figure 7-8.
The thrust bearing prevents backward deflection of
blade during cutting.
1. Disconnect band saw from power source.
2. Loosen screws (M, Figure 7-8) with 3mm hex
wrench and raise guard plate to expose thrust
bearing.
3. Loosen screw (N) with 5mm hex wrench, and
slide thrust bearing until it almost touches back
of blade. (This blade-to-bearing gap can be set
in similar fashion as the side guides, with
business card or dollar bill.)
NOTE: On narrow blades, it may be preferable
to set thrust bearing in actual contact with
blade.
4. Tighten screw (N).
5. Lower guard plate (M) and tighten in place.
6. Make sure all screws and lock knobs on upper
guide bearing assembly are tightened when
adjustments are complete.
7.10
Lower blade guides
Blade teeth are sharp; use care
when working near saw blade.
Refer to Figures 7-10 and 7-11.
1. Disconnect band saw from power source.
2. Open lower door.
3. Adjust lower guide bearings and lower thrust
bearing below table in similar manner to that of
upper guide and thrust bearings.
Movement summary: Loosen screws on guide
bracket (P) to adjust bearing assembly (refer to
Figure 7-9). Loosen screws (R) and rotate
eccentric guide bearings in relation to blade.
The thrust bearing is moved forward and
backward by loosening set screw (S) with 4mm
hex wrench and rotating knob (T). Retighten set
screw (S) to secure position.
4. Make sure all knobs and screws are tightened
after adjustments are complete.
