Use and Care Manual

5. Loosen lock knob and slide left blade guide
arm (B) to the right as far as possible.
6. Remove old blade from both wheels and out of
each blade guide.
Even dull blades are sharp
to the skin. Use extra caution handling
band saw blades.
7. Install new blade making sure teeth are
pointed downward in the proper cutting
direction. If necessary, turn blade inside out.
8. Position blade on band wheels and tighten just
enough to hold blade on wheels. Make sure
back of blade rests lightly against the wheel
flange of both wheels. Twist blade slightly to
allow it to slip into guides.
9. Tension blade to approximately 25,000 lbs. of
blade tension, as indicated on the blade
tension indicator found on the tension wheel
shaft housing.
10. Attach wire brush to the wire brush post with
screw and washer. Adjust wire brush post so
that brush just comes into contact with blade
teeth.
11. Close all covers and guards and fasten
securely. Connect machine to power and run
freely for approximately two minutes.
12. Turn power off and re-check blade tension and
wire brush adjustment. If further adjustment is
necessary, disconnect saw from power source,
make adjustments, and re-connect to power.
12.5 Blade tracking adjustment
Blade tracking has been set at the factory and
should not require adjustment. If a tracking
problem occurs, adjust the machine as follows:
Tracking adjustment is done
with the wheel covers open to observe the
blade. Use extreme caution so that you do not
come into contact with the blade.
Since tracking can only be adjusted while machine
is running, it is suggested that this adjustment be
accomplished by qualified personnel that are
familiar with this type of adjustment and the
dangers associated with it.
1. Disconnect machine from power source.
2. Raise saw arm to its highest position and close
cutting pressure control valve to hold saw arm
in place.
3. Locate tracking adjustment plate on the back
side of the driven blade wheel.
4. Loosen the three bolts (A, Figure 8) located on
the top of the tracking nuts.
Figure 8
5. Tracking adjustment is accomplished by either
loosening or tightening three adjusting nuts (B,
Figure 8).
6. Tracking is set properly when the back of the
blade lightly touches the wheel flange. Note:
Over-tracking (allowing blade back to rub hard
against wheel flange) will damage the blade
wheels and blade.
7. Tighten locking bolts (A) once proper tracking
is completed.
8. Connect machine to the power source.
12.6 Automatic shut-off adjustment
The motor should shut off immediately after the
blade has cut through the material and just before
the head comes to rest on the horizontal stop bolt.
If the machine continues to run after the workpiece
has been fully cut, locate and adjust the micro
switch mounting plate down. If the machine shuts
off before the workpiece has been completely cut,
move the micro switch mounting plate up.
12.7 Thrust roller adjustment
1. Disconnect machine from the power source.
2. Loosen two hex socket cap screws (A, Figure
9). Note: Left guide roller has two hex socket
cap screws; right guide roller has one (HBS-
916W only). The HBS-1018W has two screws
on each guide.
3. Move guide seat (B) up or down until a
clearance of .003” to .005” between back of
blade and thrust roller is obtained.
4. Tighten two hex socket cap screws (A).
5. Repeat for other blade guide assembly.
6. Connect machine to power source.
