8. Remove the blade from both wheels (5B) and out of
each blade guide.
9. Place the new blade onto the wheels and work the blade
all the way up between the blade guide bearings. Make
sure the blade back is against the vertical roller bearing.
10. The blade clip will automatically release from the blade
when the blade starts moving.
11. Slowly to turn the blade tension lever (3B) to the half way
to the "Tighten" position, check and adjust the blade hold
on the blade wheels, then turn the lever to the tighten
position to perform blade tension. The saw blade will be
tensioned to the proper default tension.
12. Slide the left blade guide arm back to the left position.
13. Tighten the adjusting knobs (2B) so the tungsten carbide
guides will properly fit to the blade.
14. Close the wheel cover (1B).
15. Connect the machine to the power, and turn the Manual/
Auto switch (D pg. 6) to manual mode.
16. Use the saw bow control knobs (X and Y pg. 6) to adjust
the down-feed speed to zero. .
17. Press the Bench Vise Close button (H pg. 6) until its
indicator light illuminates.
18. Press the Operation Start Button (E pg. 6) to start the
blade moving. After approximately two revolutions, press
the Bow Up Button (F pg. 6) to stop the blade.
19 Open the wheel cover to see that the blade has not come
off the wheels and is securely pressed against roller
bearings.
20. Adjust the position of the wire brush to the gullets of the
saw blade, then tighten it with the lock lever (4B).
NOTE: In case the blade needs to be replaced, make sure to
always install a blade of same thickness as the original
blade.

Breaking in the new saw blade
When a new blade is installed, be sure to break in the blade
before using it for production. Failure to break in the blade will
shorten the service life of the blade, and result in less than
optimum performance. To break in the blade, proceed as follows:
•
Reduce the blade speed setting to one half of its normal
setting.
•
Lengthen the time required for cutting to 2-3 times longer
than normal.
•
The break-in operation can be considered sufficient if all
unusual noises or metallic sounds have been eliminated.
•
For instance, to completely break in the blade, a minimum of
five complete cuts at 8" in diameter are required.
•
After the break-in operation has been completed, return the
blade speed and feed rate to their normal setting.
Blade tracking adjustment

8B
The blade tracking (shown above) is set by the factory and
should not require any adjustment. The tracking adjustment must
be made by a qualified personnel that are familiar with this type
of procedure.
•
Adjust the saw blade so that the back of the blade lightly
touches the flange of blade wheels.
•
Use the blade clip to hold the saw blade in place.
If a tracking problem occurs, adjust the machine as follows:
•
Raise saw arm to a usable height.
•
Completely disconnect the machine from its power
source.
•
Locate tracking adjustment bolt on the backside of the
saw bow behind the flywheel.
•
Loosen nut (8B) and bolt (6B).
•
Tracking adjustment is accomplished by either loosening
or tightening the adjusting tracking nut (7B).
•
Tracking is set properly when the back of the blade lightly
touches the wheel flange.
