dictate tooth selection.
912(B.G) 912(DR.GDR)

- 9 -
TOOTH
SELECTION
You need to consider:
1. The width of the cut. That is, the distance in the cut that each tooth must travel from the point it
Enters the work piece until it leaves the work piece, and
2.The shape of the work piece.
Squares, Rectangles, Flats (Symbol :
 )
Locate the width of cut on the chart. (Inches on the outer circle and millimeters on the
inner circle.) Select the tooth pitch on the ring marked with the square shape which aligns
with the width of cut.
EXAMPLE: 6" (150mm) square, use a 2/3 Vari-Tooth.
Round Solids (Symbol : 

 )
Locate the diameter of your work piece on the chart. Select the tooth pitch on the ring
marked with the round shape which aligns with the size of stock you are cutting.
EXAMPLE: 4" (100mm) round, use a 3/4 Vari-Tooth.
Tubing, Pipe, Structurals( Symbol : O H ^ )
Determine the average width of cut by dividing the area of the work piece by the distance
the saw blade must travel to finish the cut. Locate the average width of cut on the chart.
Select the tooth Ditch on the ring marked with the tubing and structural shape which
aligns with the average width you are cutting.
EXAMPLE: 4"(100mm) outside diameter, 3"(75mm) inside diameter tubing.
4"(100mm) OD=12.5 sq.ln. (79cm2)
3"(75 mm) ID = 7.0 sq.ln. (44cm2)
Area = 5.5 sq.ln. (35cm2)
5.5 sq.ln. (35cm2) / 4" (100mm) distance =1.38(35mm) average width
1.38" (35mm), use a 4/6 Vari-Tooth
NOTE: The band speed and cutting rate recommendations presented on this chart are
approximations and are to be used as a starting point for most applications. For exact
sawing parameters' consult your saw blade supplier.

Blade Direction
STARTING SAW
Switch button function description
CAUIION: NEVER OPERATE SAW WITHOUT BLADE GUARDS IN PLACE.
Be sure the blade is not in contact with the work when the motor is started. Start the motor, allow
the saw to come to full speed, and then begin the cut by letting the head down slowly onto the work.
DO NOT DROP OR FORCE. Let the weight of the saw head provide the cutting force. The saw
automatically shuts off at the end of the cut.
BLADE SELECTION
An 8-tooth per inch, general-use blade is furnished with this metal Cutting Band Saw. Additional
blades in 4, 6, 8, and 10 tooth sizes are available. The choice of blade pitch is governed by the
thinness of the work to be cut: the thinner the work piece, the more teeth advised. A minimum of
three (3) teeth should engage the work piece at all times for proper cutting if the teeth of the Blade

8. BLADE GUIDE BEARING ADJUSTMENT
ATTENTION: This is the most important adjustment on your saw. It is impossible to get
satisfactory work from your saw if the blade guides are not properly adjusted. The blade guide
bearings on your metal. Cutting Band Saw are adjusted and power tested with several test cuts
before leaving the factory to insure proper setting The need for adjustment should rarely occur
when the saw is used properly. If the guides do get out of adjustment though, it is extremely
important to readjust immediately. If improper adjustment in maintained, the blade will not cut
straight, and if the situation is not corrected it will cause serious blade damage. Because guide
adjustment is a critical factor in the performance of your saw, it is always best to try a new blade to
see if this will correct poor cutting before beginning to adjust. If a blade becomes dull on one side
sooner than the other, for example, it will begin cutting crooked. A blade change will correct this
problem the guide adjustment will not. If a new blade does not correct the problem, check the blade

- 17 -
guides for proper spacing.
NOTE: There should be from 000 (just touching) 001 clearance between the blade and guide
bearings to obtain this clearance adjust as follows:
1. The inner guide bearing is fixed and cannot be adjusted.
2. The outer guide bearing is mounted to an eccentric bushing and can be adjusted.
3. Loosen the nut while holding the bolt with an Alien wrench.
4. Position the eccentric by turning the bolt to the desired position of clearance.
5. Tighten the nut.
6. Adjust the second blade guide bearing in the same manner.
REMARK:
1. Adjust the tension of blade until the back of the blade (A) against the blade wheel (front)
lightly.
2. Be sure the nut (E) is tightened.
3. Turn the eccentric shaft (B) counterclockwise, when the bearing (D) touches the saw blade
properly; tighten the nut (E).
4. To adjust, loosen set screw(F) and move the blade adjustable up or down until it lightly
Touches the back of the blade (A).
5. The carbide blade guides(L)Fig.1,should also be adjusted so they lightly touch the blade
by loosening screws (M).
6. Repeat 1. 2, 3, 4and 5 steps to adjust the other side's blade guide bearings (G).
7. Correct the base and blade to be a vertical position with a scale. If necessary, loosen set
screw (F).
8. Set down the blade frame, correct the jaw vise (H) and blade to be a vertical position with a
Scale then tighten the set screws (I).
9. Loosen set screw (K), move front jaw vise (J) to against rear jaw vise (H) tightly. Finish
Correcting by tightening set screw (K)

9. BLADE TRACK ADJUSTMENT
(1). Open the blade guard.
(2). Remove the blade guide assemblies (top and bottom)
(3). Loosen the hex head screw in the tilting mechanism to a point where it is loose but snug.
(4). with the machine running, adjust both the set crew and blade tension knob simultaneously to
keep constant tension on the blade. The set screw and blade tension knob are always turned in
opposite directions, i.e., when one is turned clockwise the other is turned counterclockwise.
The blade is tracking properly when the back side just touches the shoulder of pulley or a
slight gap appears near the center line of the pulley. Care should be taken not to over-tighten
the saw blade since this will give a false adjustment and limit life of the blade.
(5). Tighten the hex head screw in tilting mechanism. IMPORTANT: Sometimes in trying to
make this critical adjustment it is possible to cause the basic setting to be misaligned. Should
this occur, proceed as follows:
a. Loosen the set screw and back it out as far as it can go and still remain in the threaded hole.
b. Turn the hex head screw clockwise until it stops (do not tighten).
c. Turn the set screw clockwise until it bottoms, then continue for half a turn and check the
tracking by turning on the machine.
d. If further adjustment is required, go back to step 4.
(6). Turn off power to the machine.
(7). Replace the clad guide assemblies--it may be necessary to loosen the blade tension lightly.
(8). Adjust the vertical position of blade guide bearing assemblies so that the back side of the
blade just touches the ball bearing.
(9). Make a final run to check tracking. It required, touch up adjustment (See stop 4)
(10). Replace the blade guards.
Hydraulic Feed Adjustment
(1) To adjust the feeding rate when in cutting, turn the volume valve (A) clockwise for faster
feeding, counterclockwise for slower feeding.
(2) When cutting feed is too fast, raise the saw arm, then slower the feed rate to prevent blade
damage.
10. MAINTENANCE
