8.9 Installing/changing blades
Always wear gloves when
handling blades. New blades are usually
packaged in coiled position; to prevent injury
uncoil them slowly and carefully, while wearing
work gloves and safety glasses.
The JWBS-14SF band saw is designed for blades
from 1/8” to 3/4” wide.
Refer to Figures 16,17,18.
1. Disconnect machine from power source.
2. Loosen lock handle (A, Figure 16) and slide
out block (B).
Figure 16
3. Adjust upper and lower blade guides away
from blade (see sections 8.13 and 8.15).
4. Move quick tension lever to “Full Release
(Blade Change)” position.
5. Open upper and lower doors by rotating door
knobs.
6. Loosen knob (C, Figure 17) and pivot guide
post cover out of the way.
Figure 17
7. Loosen knob (D, Figure 18), pull out on lower
guard (E), then swing lower guard to the left.
Tilt table slightly if more clearance is needed to
swing guard.
8. Carefully remove blade from top wheel, then
from between upper and lower blade guides
and lower wheel. Slide blade out through slot
in table.
Figure 18
9. Guide new blade through table slot. Place
blade loosely in upper and lower blade guides.
Make sure blade teeth point down toward
table, and toward front of saw. (If the teeth will
not point down, no matter how you orient
blade, then blade is inside-out. Twist it into
correct position and re-install it.)
10. Position blade at center of upper and lower
wheels.
11. Reinstall table block (B, Figure 16) and tighten
knob (A).
12. Before operating band saw, the new blade
must be tensioned and tracked, in that order.
Find instructions for tensioning and tracking
the blade in sections 8.10 and 8.11. The blade
guides must also be set properly according to
instructions in sections 8.13 through 8.15.
8.10 Blade tension
Refer to Figure 19.
1. Disconnect machine from power source.
2. Back off upper and lower guide bearings to
eliminate any contact with blade.
3. With blade centered on wheels, move blade
tension handle to “Full Tension” position, as
shown in Figure 19. NOTE: You should feel
tension handle settle into each of its three
positions.
