SAFETY
1. Know your band saw. Read the operator’s Manual carefully. Learn the
operations, applications and limitation.
2. Use recommended accessories. Improper accessories may be
hazardous.
3. Wear proper apparel.
4. Keep unnecessary people away.
5. Don’t overreach or stand on tool.
6. Avoid dangerous environment. Don’t use band saw in damp or wet
locations. Keep work area well lighted.
7. Keep work area clean. Cluttered and slippery floors invite accidents.
8. Remove adjusting keys and wrenches from band saw before turning on
power.
9. Avoid accidental starting. Mark sure switch is off before plugging in
power cord.
10. Don’t force band saw. It is safe to operate at the cutting rate for which it
was designed.
11. Be specially careful when using band saws in vertical position to keep
fingers and hands out of the path of blade, both above and beneath the
table.
12. Never hand hold the material with saw in horizontal position. Always
use the vise, clamp securely.
13. Keep belt guard and wheel covers in place and in working order.
14. Support long, heavy work from the floor.
15. Always remember to switch off the machine when the work is
completed.
16. Disconnect power cord before adjusting. Servicing and changing
blade.
17. Check damaged parts. Damaged parts must be replaced or repaired.
18. Moving parts should keep in alignment. All adjustments are to be made
with power disconnected.
19. Use a sharp blade and keep tool clean for best and safest
performance.
20. Safety is a combination of operator’s common sense and alertness at
all times when the saw is functioning.
21. Keeping the band saw in top condition is essential for safety.

BLADE GUIDE BEARING ADJUSTMENT
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 for 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 to get out of adjustment, it is
extremely important to readjust immediately. If proper adjustment is not
maintained, the blade will not cut straight and if the situation is not
corrected, it will cause 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 the bearings. If a blade becomes dull on
one side sooner than the other, for example, it will begin cutting crooked. A
simple blade change should correct this problem-the more difficult guide
adjustment will not.
If a new blade does not correct the problem, check the blade guides for
proper spacing.
There should be 0.001’’ clearance between the 0.025’’ thickness blade
4
and guide bearing. 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 bolt and can be
adjusted.
3. Loosen the nut while holding the bolt with a 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.
7. The back edge of the blade should just touch the lip of the Blade Guide
Bearing.
BLADE GUIDE ASSEMBLY ADJUSTMENT
The Metal Cutting Band Saw is equipped with two adjustable blade guide
assemblies. This feature will permit you to adjust the position of the blade
guide for various widths work pieces.
To effect the most accurate cut and prolong the life of the blade. The blade
guide assemblies should be adjusted to just clear the piece to be cut. This
is done as follows:
1. Place the work piece in the vise of band saw and clamp tightly.
2. Adjust catch blade guide assembly to the desired position by loosening
the hand knobs and positioning the guides required.
3. Tighten the hand knobs.
ADJUSTING BLADE TENSION
1. Make sure the motor is
shut off.
2. Press the blade lightly with
left hand, make the rear
blade against the flange of
blade wheel and test the
blade tension.
3. Adjust the blade tension
adjustable knob with the Figure (1) Adjusting Blade Tension
right hand until the blade obtain the proper tension.
CHANGING SPEED
1. When using your Band Saw, always change the blade speed to best
suit the material being cut. Cutting chart is shown in figure (2).

2. Cut off power. Open the pulley guard cover. Loosen the lead screw

BLADE SELECTION
1. Special note: 1(1/2’’ x 0.025’’x 641/2min, 651/2max) tooth per inch
general use blade is furnished with the metal cutting Band Saw.
Additional blades in 10 and 14 tooth sizes are available.
2. The choice of blade pitch is governed by the thickness of the work to be
cut; the thinner the work piece, the more teeth advised. A minimum of 3
teeth should be in the work piece at all times for proper cutting.
3. If the teeth of the blade are so far apart that they straddle the work,
server damage to the work piece and to the blade can result.
CHANGING BLADE
Raise saw head to vertical position. Loosen blade tension adjustable knob
sufficiently to allow the saw blade to slip off the wheels. Install the new
blade as follows:
1. Place the blade in between each of guide bearing.
2. Slip the blade around the motor pulley (bottom) with left hand and hold
in position.
3. Hold the blade taut against the motor pulley by pulling the blade
upward with the right hand which is placed at the top of the blade.
4. Remove left hand from bottom pulley and it s the top side of the blade
to continue the application on the upward pull on the blade.
5. Remove right hand from blade and adjust the position of top pulley to

6. Adjust the blade tension knob clockwise until it is just right enough so
no blade slippage occurs. Do not tighten excessively.
7. Place 2-3 drops of oil on the blade.
8. Replace the blade guard.
ADJUSTING THE BLADE TRACKING
This adjusting has been completed and power-tested at the factory. The
need for adjusting should rarely occur when the saw is used properly. If
the tracking goes out of adjusting is listed below:
Figure (3)
HORIZONTAL CUTTING OPERATION
Before operating, please read instruction manual and examine every part
including speed, Blade selection, guide assemble position, etc. Operation
is as follows:
WORK SET UP
1. Raise the saw head to the vertical position.
2. Open the vise to accept the piece to be cut by rotating the wheel at the
end of base (counter clockwise).
3. Place the work piece on the saw bed. If the price is long, support the
end.
4. Clamp the work piece securely in the vise by rotating the hand wheel
clockwise.
7
CUTTING
Close switch, 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 end of the cut.
Method of adjusting blade:
A. Loosen the screw #11.
B. Adjust the blade adjustable seat #64 to make the blade vertical to bed.
C. Place the square on the bed to check if the blade is vertical, if not,
repeat the process A to C.
D. Tighten the screw #11.

LUBRICATION
Lubricate the following components using lubricant, L-HV32
1. Ball bearing –none.
2. Blade guide bearing-none
3. Driven wheel bearing-none.
4. Vise lead screw- as needed.
5. The driven gears run in the bath and will not require a lubricant change
more than then once a year. When needing a change, first put down
the bead to a Horizontal position, then loosen 4 screw (#75) of the gear
box open the cover (#93). Placing a pan under the tight lower corner of
the gear box, slowly raise the head until the oil flows out, Lower corner
of the gear box, slowly raise the head until the oil flows out, Lower head.
Then wipe up excess oil and foreign matter with soft rags. Then add
lubricant into the box until it is full and not flow over. Close the cover,
tighten 4 screws.
