Blade Replacement; Bow Stop - Jet HBS-814GH Operating Instructions And Parts Manual

Blade Replacement

A general-use variable-tooth blade is provided
with this metal cutting band saw. Additional
blades can be used and are available from your
JET distributor.
The choice of blade pitch is governed by the
thickness of the work to be cut: the thinner the
workpiece, the more teeth advised. A minimum
of 3 teeth should engage the workpiece at all
times. If the teeth of the blade are so far apart
that they straddle the work, severe damage to
the workpiece and to the blade can result.
1. Disconnect machine from power source.
2. Loosen the handle (Figure 17) and move
the blade guides away from the wheel, as
shown in Figure 19.
3. Raise the bow, making sure the hydraulic
cylinder is closed so the bow will remain
stationary.
4. Open the back cover, by loosening the two
knobs and the four screws on the brackets.
5. Loosen tension on the blade.
6. Remove the blade from between the guides
and from around the wheels. (Use gloves
when handling sharp blades!).
7. Install new blade on wheels, making sure
the teeth point downward in the proper
cutting direction. See Figure 20; also notice
the blade direction arrow on the front of the
bow.
8. Increase blade tension just enough to hold
the blade on the wheels. Make sure back of
blade rests lightly against the shoulder of
both wheels.
9. Twist blade slightly to allow it to slip into the
guides.
10. The blade should be tensioned and tracked
properly before use. See "Blade Tension"
and "Blade Tracking" above.

Bow Stop

The stop screw (Figure 21) controls the depth of
fall of the bow to prevent the blade from hitting
the bed casting. The stop screw has been set at
the factory. If future adjustment is needed,
loosen the hex nut and rotate the screw, then re-
tighten the hex nut.
