IV. DESCRIPTION OF THE MACHINE AND ITS COMPONENTS
The band sawing machine produced by us has a sturdy frame made from welded and
painted sheet-steel. The upper surface is designed to allow the complete draining away of
the cutting fluid. The band holding bow is made of cast-iron and has generous dimensions，
providing the cutting unit with the necessary strength and precision. The vice unit is made
of cast-iron and clamps the material to be cut securely. The bar-stop device allows the
length required to be preset and a constant level of performance for repeated cuts. The
blade-holding bow is firmly attached to a reduction unit built onto the motor and to the base
by means of a joint which allows 60°rotation to the right. This joint also allows the cutting
movement to advance manually or by falling.
Tank is fitted near the machine table. The main switch is located on the front panel. The
choice of one of the two motor rotation speeds and therefore cutting speed is carried out by
the main switch. The front panel is also fitted with an emergency stop button and a START
button. The control lever，fitted with an ergonomic hand-grip and activation button with
safety release action, reduces fatigue during operation to a minimum. The blade is
protected by a guard with interlock which covers the upper area and the hand wheels and
by two adjustable lower guards which protect the operator from ejected shavings and
coolant. The machine is supplied with a set of service spanners.

2. The adjusting screws, above and under the Band Guides, can be adjusted as long as.
3. The worktable can be titled.
4. This manual has been prepared for the operator who operates, and the maintenance of
the Vertical Saw. The purpose is to promote safety through the use of accepted
operation procedure.
The following instructions in operations and maintenance shall be observed in order to
obtain the maximum efficiency of the unit.
The procedure is shown as follows:
A. Power
B. Sawing material selection
C. Blade selection
D. Blade cutting device
E. Welder
F. Grinder
G. Blade installation

L. Safety and maintenance
M. Inverter parameters
ACTION TAKEN
A. Power
1. First, before operating the machine, be sure to check the voltage which is in accordance
with the power supply system.

6
B. Sawing Material Selection:
Before sawing, the operator must fully understand the quality of the sawing material.
Example: With super high stencil steel, the machine should be run at a slower speed.
Otherwise, the blade will overheat, be worn or broken easily. With thin material, it is
recommended to use a wider blade pitch at high speeds; otherwise, the teeth will be ruined
easily.
C. Blade Selection:
1. Generally, there are three different types of blade. These are used for metal materials
such as steel, brass, iron and aluminum or non-metal such as wood, plastic, rubber and
paper materials.
2. Selection of the blade pitch is essential. As a general rule, the thicker the material the
less teeth per in pitch, and a wider blade should be used.
3. When cutting ‘Radius’ – the smaller the ‘Radius’ the narrower the blade.
4. Refer to the Speed & Pitch Selector guide on the machine for proper radius and pitch.
D. Blade cutting Device: Use the Blade cutter only for cutting blades if you want to
maintain the cutter for a long period of time. Do not use it as a general purpose cutter.
E. Welder: Reference as the following
1. Prepare before welding
a. Cleaning the blades and cut the two ends straight with the cutter. Use grinding wheel
deburring the ends if necessary.
b. Put the blade ends on the clamping points separately, and make sure the two ends
contact closely. Then, turn the clamping handles to outsides and lock the electrode
to blades.
c. Adjust voltage knob according to the blade thickness. The more thickness, the
higher voltage (Turn the knob clockwise for higher voltage). The normal setting is 4
position.
2. Welding operation
a. Use your Thumb to press the Welding Button, then blade change to Red color and
activities electrode driven the blade feed for welding. Please do not release the Weld

7
Button during the welding until the blade back to black color.
3. Tempering operation
a. Press the tempering button until the welding points begin to appear red color. Then,
after the blade back to the normal color, do the previous action again. Repeat this
pressing 5-7 times. Please do not keep pressing over 3 seconds each time. Before
tempering, please release the two clamping points first, then re-fix them in 1.b step.
4. Weld dressing
a. Turn the clamping handles in vertical position and take blade out. Start the grinding
wheel to polish the over parts. Then, the blades can be reused.

8
Maintenance and trouble shooting
1. Maintenances
a. put the voltage adj. knob back to mark of “i” when the machine is not working
b. after half hour working, the machine can only be continue to work when the temperature
is lowing down to the ambient temperature
2. trouble shooting
If the cut welding is not work, then open the panel, removal the switch of cut welding
according to picture 2,polish the touch point by sand cloth,, then put on the switch of cut
welding again, at this time, the insulation stick should jack-up the switch of cut welding,
separate the second touch point. According to the time of welding needed to adjust the
distance A. The bigger distance in A, the longer time for welding melt.
Trouble
Possible Reason
Solution
Welding
seam broken
a. Blades welding end is dirty
b. Not proper welding voltage
c. Two ends is not align
d. Two ends do not melt at the
same time.
a. Cleaning the blades with clothes.
b. Increase the welding voltage.
c. Align the blade Two ends.
d. Adjust the “adjusting screw” in the
clamping plate, to align the center of
clamping roller and the bottom bolt.

9
Trouble
Possible Reason
Solution
Blade do not
melt
a. Blade two ends is not
straight and flat
b. Electrode is broken or worn.
c. Cut welding switch not work
d. Blade two ends do not
contact.
e. Blade clamping points have
rust.
a. Cut the two ends straight and flat.
b. Repair the electrode.
c. Polish the touch points of the switch
by sand cloth.
d. Re-cut the blade two ends.
e. Remove the rust by sand cloth.
Blade cannot
clamp tightly
The distance between the
clamping roller and bottom bolt
is big.
Adjust the “adjusting screw” in the
clamping plate, to align the center of
clamping roller and the bottom bolt.
F. Grinder:
The grinder is used for grinding off both ends of the cut blade on the surface so that the
blade can be welded together easily. Note: Do not exceed in running the grinder for more
than 30 minutes at a time.
G. Blade Installation:
First turn off power and open the safety covers; then take off the old blade by turning the
blade tension hand wheel and removing the guide bar from the table. Replace the blade
with the teeth in the downward position. Be sure the safety covers have been closed.
H. Guide Rod Adjustment:
Adjustment to the guide rod is very essential. There are two rods: Top and Bottom. Only the
top one can be adjusted about 1mm above the sawing working piece. Note: If the
adjustment is made higher, the blade will be bent, so the support block of the supporting
blade should also be adjusted in line with the blade width and thickness. When making
adjustments, the power shall be shut off, and the support block shall be right in the middle
position of the rear of the blade teeth (neither loose nor tight).
I. Inverter Speed Selection and Operating:
J. See the Speed & Pitch selector on the front of your machine.
Operation method: Switch on; then turn motor starter switch on, and then adjust to
desirable speed by speed adjusting knob.
K. Air pump:
Voltage: 220V/60HZ Current: 0.5mA Flow rate:10-12(L/min)

10
Pressure: 0.20Kg/cm2 Type of fluid: Air
L. Angles Cutting:
1. Declination sawing: Loose table nuts; adjust the table into the desirable position,
and retighten the nuts.
2. “R” shape sawing: Turn slowly because the sawing edge must remain flat, straight
and smooth.
3. Smaller working piece sawing: Be careful to push or pull the work piece by using a
wood block (not by hand); otherwise, the operator may get hurt.
4. Internal contour: First , drill a hole through the work piece large enough to fit the
blade through. Weld the blade ends together (grinding smooth). Reinstall blade on
wheels and make normal blade adjustment. Begin to perform contour sawing.
5. Working Speed: When sawing, the speed shall remain the same (neither fast nor
slow); otherwise, blade breaking may occur.
M. Safety and Maintenance:
1. Be sure that the safety cover and the wheel doors are always closed before turning
on the machine.
2. The band saw shall be installed in a dry place in order to avoid electrical shock.
3. Make sure the machine is grounded properly (green wire to ground).
4. After installing a new saw blade, start the motor and keep the blade turning without
load about 1 minute; then proceed to cutting the work piece
5. Upon sawing, if any unusual noise, smell or blade breakage occurs, operator should
immediately switch off the power.
6. Maintenance: After operating, switch the machine off. After clearing the machine,
take away the chips, and slightly lubricate the surface of the machine and all joints
to keep them from rusting.
