Replace any guarding that was removed after blade is installed.
2. Adjust blade tension per the tension scale by turning the blade tension adjustment hand
wheel. The scale is visible from the rear side.
3. Jog the machine to see if the blade tracks properly, adjust blade tracking by turning the
tracking adjuster when it is necessary. (See blade tracking section on next page for
further details)
Proper tensioning Improper tensioning
- 8 -
BLADE TRACKING
Blade tracking may be required from time to time depending on the blade size and tension.
Disconnect the machine from the power source and open both blade wheel doors. Shift the
high-low gearbox lever into the neutral position. Turn the upper blade wheel by hand while
observing blade position on the upper blade wheel to determine if adjustment is necessary:
a.Turn blade tracking knob clockwise to track
blade toward front of blade wheel.
b.Turn counter-clockwise to track blade toward
rear of blade wheel. Blade should be tracked
as close of the center of the top blade wheel
as possible. Do not allow blade to run on the
wheel lip.
▲Note: Upper and lower blade guides should be
moved away and left loose from the blade while
tracking adjustments are being made.
GUIDE POST ADJUSTING
1. Loosen the guide post locking knob. Always
support the guide post when loosening the
guide post to prevent it from unexpectedly
falling. (Figure A next page)
2. The height of the upper guide post setting is in
relationship to the height of the material. The
height between the material and the blade
guide end is suggested to be about 1/4”. (See
figure B illustration on next page)
3. Lock the guide post tightly.
▲ WARNING
All adjustment or repairs to the machine must
be done with the power off and the machine
disconnected from the power source. Failure to
comply may result in serious injury!

Figure A Figure B
▲ It may be necessary to open the blade guides, before you adjust the guide post to
allow free movement of the guide post.
GUIDE HOLDER ADJUSTMENT
1. Loosen the inner hex screws
located at the right lower side of
guide post with an “L” shaped allen
wrench.
2. Adjust the guide holder forward or
backward according to the blade
width. The front edge of the blade
guides must be adjusted about 1/8”
behind the blade teeth. (see figure B
next page)
3. Tighten the screws securely.
BLADE GUIDE ADJUSTING
1. Loosen the inner hex screws of the blade guide with an “L” shaped allen wrench.
2. Adjust the blade guides very close to the blade but not touching the guide faces. (approx.
thickness of a business card)
3. With blade tight allow guides to ride up to the blade not forcing them off center. Tighten
the blade guides securely. (See figure A next page)
NOTE: There are a total of four blade guides and two guide holders located above the
table and under the table, all to be adjusted to the same position.
- 10 -
Figure A Figure B
The blade guides will wear after time at the
front faces. If the blade guides become hard
to be properly adjusted, turn the left blade
guide over to the right side, as illustrated in
the right illustration, and turn the right-side
blade guide over to the left side as well. The
blade guides can then be used on both sides
getting more mileage out of the guides.
The backup blade guide button will wear over
time as friction from the saw blade may cause
a worn line on its surface. If this is found to
happen, loosen the lower guide holder bolt
and turn it to rotate the button shaft to change
the buttons position on the saw blade.
▲ CAUTION
Blade guide must be properly adjusted
or damage may occur to the blade and/or
the guides.
BLADE SELECTION
To get the most satisfactory work from your saw, it is important to choose a blade that is
correct for the work. Blade life, cut straightness, finishing quality and sawing efficiency is all
related to the choice of blade. Blade breakage, teeth stripping, crooked cuts, and other
common complaints are, in most instances, caused by using the wrong blades. Blades are
classified by materials, tooth shapes, and types of set.
- 11 -
TYPES OF BLADES
Bandsaw blades are available in specific sizes, or in 100 feet coils. They are made from
several different metals:
1. Carbon Steel Blade: which are widely used because of their general adaptability for all
types of work and the low cost. They are excellent for cutting nonferrous metals and
plastics.
2. High-Speed Steel Blade: which resist heat generated in cutting to far greater extent than
carbon steel blades. They are best suited for cutting ferrous metals.
3. Alloy Steel Blade: which are tougher and more wear resistant than either of the above.
They will cut faster and longer than blades of carbon or high-speed steel.
4. Carbide-Tipped Blade: which are best used for cutting unusual materials such as
uranium, titanium, and beryllium. These metals are difficult to cut with other types of
blades.
TOOTH SHAPES
The regular or standard tooth is preferred for all ferrous metals and general-purpose cutting.
The skip-tooth blade has widely spaced teeth to provide the added chip clearance needed
for cutting softer nonferrous materials. The hook, or saber tooth blades has a 10°undercut
which permits better feed and chip removal, it is best for the harder nonferrous alloys.
SET TYPES
Regular or rake set is generally furnished on saws that have 2 to 24 teeth per inch. These
blades have one tooth set to left, one to right, and one unset tooth called a rake. This set is
used when material is to be contour cut. Wavy set is furnished on saws that have 8 to 32
teeth per inch. This set has groups of teeth bent alternately to left and right, which greatly
reduce the strain on individual teeth. Saws with wavy set are used where tooth breakage is
a problem, such as in cutting thin stock or where a variety of work is cut without changing
blades.
Of the three common set patterns, only raker and wave are now used in metalworking.
Always use rake set except:
For work of varying cross
section use wave set.
When one blade must be
used for a range of material
sizes use wave set

▲ PLEASE NOTE THAT CORRECT BLADE SELECTION IS VERY IMPORTANT TO
BANDSAW OPERATING AT FULL POTENTIAL. ALWAYS SELECT A BLADE
ACCORDING TO THE MATERIAL SHAPE AND THICKNESS OF THE WORK
Always break in the blade per blade manufactures recommendations.

Please refer to the “Speed & Pitch Selector wheel that is supplied on your saw for speeds
and feeds, radius cutting and blade pitch selection.
Select saw blades in relationship to the thickness of materials. The following suggestions
are a rule of thumb to consider when selecting a blade.
A. Select a larger pitch blade for a thicker material.
B. Select a smaller pitch blade for a thinner material.
C. Use a smaller pitch blade to obtain a smooth cutting surface.
D. Use a larger pitch blade to obtain a faster cutting speed.
E. It is important to have different blades for different applications
- 14 -
WELDER OPERATION
This welder is for occasional use for blade repair and is not intended for welding blades on a regular basis
from bulk stock. This welder is best suited for carbon bands but with practice both carbon and bi-metal can
also be welded.
BLADE CUTTING
1. Cut the blade to the length of the
machine. Using the blade shear will insure
that the blade ends are cut flat, square and
smooth.
2. Place the back edge of blade against the
square cutting guide of the shear and firmly
pull the cutting lever down to shear the
blade. Both ends of the blade must be
sheared to allow for a good butt weld.
3. Keep the shear blade clean and free from
blade end pieces that can get trapped in the
shear.
Using the Blade Shear.
TOOTH SPACING
1.On fine-pitched blades, one or more teeth on each side of the cut must be removed by
grinding so that the cross section of the weld area of the blade is uniform. Following
these guidelines will help make the teeth uniformly spaced after the weld.
- 15 -
▲CAUTION: If the saw blade is rusty, the rust must be ground off before the blade is welded.
WELDING
1. Turn pressure knob to “0” position.
2. Butt blade ends together and locate joint in the center between the two
electrodes.
3. Set pressure knob to blade width. (Due to the different materials and thickness of
blade, please pay especial attention to the pressure adjustment. Thicker the
blade higher the pressure setting.)
4. Press and hold welder button. Do not release until the blade joint is “red” hot.
The switch is automatic and will shut welder off after a preset time of 3 or 4
seconds and the blade returns to original color. Note: The weld joint may throw
sparks during welding so wear safety glasses and proper apparel.
ANNEALING (Carbon Blades)
1. Turn pressure knob to “0” position.
2. Release blade and center the weld joint at the front of the electrodes. (At the wider part)
3. Press and jog the annealing switch button until the weld is a “dull cherry” to “cherry red”
color. Allow the blades to cool slowly by decreasing the jogging frequency.
4. Perform the annealing operations 4 or 5 times, gradually reducing the heat each time.
5. Remove any welding dust or scale from the joint and anneal 2 or 3 more times,
successively at lower temperatures. (quicker series of press and release of annealing
button)
- 16 -
ANNEALING (Bi-Metal)
Set up blade for annealing as mentioned above for carbon blades steps 1 & 2.
Heat the band slowly by jogging the
annealing switch button until the weld
just begins to emit light (this would be
the dullest red color) or minute puff of
smoke. The desired color may not be
visible in normal room light. Always
shade the weld area with your hand.
Cool the weld quickly by releasing the
annealing button. Repeat this
operation 4 or 5 times.
▲NOTE: This procedure should be followed both before and after grinding
BI-METAL Blades.
GRINDING THE WELDED BLADE
▲ WARNING
Keep hands away from rotating grinding wheel. When not in use make, sure
wheel is covered with built in cover
After welding, the blade must be dressed to remove excess metal or flash from the weld.
Grind the welded area down to the same thickness as the rest of the band. Handle the blade
carefully.
Grind Carefully: do not hit the teeth; or grind deeper than the thickness of the blade; or
overheat the weld area. Be sure to remove flash from the back edge of the blade. Any flash
or “stub” teeth that project beyond the normal set or height of the other teeth must be
ground off.
Anneal the welded area that was ground again. Anneal 2 or 3 times using a lower
temperature. (Just as area starts to emit light)
- 17 -
INSPECION OF THE WELD
When the blade is removed from the
welder it should be inspected
carefully.
The spacing of the teeth should be
uniform and the weld should be
located in the center of the gullet.
Major jaw misalignment is easily
noted at this time from the weld
appearance. See the trouble shooting
chapter if the weld is imperfect.
▲CAUTION: This welder is designed for intermittent use. Repeated welding
within a short period of time may cause the welder to overheat.
