WARNING: FAILURE TO FOLLOW THESE RULES

MAY RESULT IN SERIOUS PERSONAL I NJU RY

As with all machinery there are certain hazards involved with operation and use of the machine. Using the machine with
respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are
overlooked or ignored, personal injury to the operator may result.
This machine was designed for certain applications only. We strongly recommend that this machine NOT be modified
and/or used for any application other than for which it was designed. If you have any questions relative to its application
DO NOT use the machine until you contact with us and we have advised you.

Your machine might not come with a power socket or plug. Before using this machine, please do ask your local
dealer to install the socket or plug on the power cable end.

2.SAFETY RULES FOR ALL TOOLS

A. USER:

(1). WEAR PROPER APPAREL. No loose clothing, gloves, rings, bracelets, or other jewelry to get caught in
moving parts.
Non-slip footwear is recommended. Wear protective hair covering to contain long hair.
(2). ALWAYS WEAR EYE PROTECTION. Refer to ANSLZ87.1 standard for appropriate recommendations.
Also use face or dust mask if cutting operation is dusty.
(3). DON'T OVERREACH. Keep proper footing and balance at all times.
(4). NEVER STAND ON TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally
contacted.
(5). NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't leave tool until it comes to
a complete stop.
(6). DRUGS, ALCOHOL, MEDICATION. Do not operate tool while under the influence of drug, alcohol or any
medication.
(7). MAKE SURE TOOL IS DISCONNECTED FROM POWER SUPPLY. While motor is being mounted,
connected or reconnected.
(8). ALWAYS keep hands and fingers away from the blade.
(9). STOP the machine before removing chips.
(10). SHUT- OFF power and clean the BAND SAW and work area before leaving the machine.
(11).DO NOT Touch the cutting Blade while the machine is turm on.

B. USE OF MACHINE:

(1). REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that keys and adjusting
wrenches are removed from tool before turning it "on".
(2). DON'T FORCE TOOL. It will do the job better and be safer at the rate for which it was designed.
(3). USE RIGHT TOOL. Don't force tool or attachment to do a job for which it was not designed.
(4). SECURE WORK. Use clamps or a vise to hold work when practical. It's safer than using your hand frees both
hands to operate tool.
(5). MAINTAIN TOOLS IN TOP CONDITION. Keep tools sharp and clean for best and safest performance.
Follow instructions for lubricating and changing accessories.
(6). USE RECOMMENDED ACCESSORIES. Consult the owner's manual for recommended accessories. The use
of improper accessories may cause hazards.
(7). AVOID ACCIDENTAL STARTING. Make sure switch is in “OFF” position before plugging in power cord.

(8). DIRECTIONOF FEED. Feed work into a blade or cutter against the direction of rotation of the blade or cutter

only.

(9). ADJUST AND POSITION the blade guide arm before starting the cut.
(10). KEEP BLADE GUIDE ARM TIGHT, A loose blade guide arm will affect sawing accuracy.
(11). MAKE SURE blade speed is set correctly for material being cut.
(12). CHECK for proper blade size and type.
(13). STOP the machine before putting material in the vise.
(14). ALWAYS

have stock firmly clamped in vise before start i ng c ut.

(15). GROUNDALL TOOLS. If tool is equipped with three-prong plug, it should be plugged into a three-hole

electrical receptacle. If an adapter is used to accommodate atwoprong receptacle, the adapter lug must be attached to a
known ground. Never removed the third prong.

C. ADJUSTMENT :

MAKE all adjustments with the power off. In order to obtain the machine. precision and correct ways of adjustment
while assembling, the user should read the detailed instruction in this manual.

D. WORKING ENVIRONMENT:

(1). KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
(2). DON'T USE IN DANGEROUS ENVIRONMENT. Don't use power tools in damp or wet locations, or expose
them to rain. Keep work area well-lighted.
(3). KEEP CHILEREN AND VISITIORS AWAY. All children and visitors should be kept a safe distance from
work area.
(4). DON’T install & use this machine in explosive, dangerous environment.

E. MAINTENANCE:

(1). DISCONNECT machine from power source when making repairs.
(2). CHECK DAMAGED PARTS. Before further using of the tool, a guard or other part that is damaged should be
carefully checked to ensure that it will operate properly and perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should be properly repaired or replaced.

(3). DISCONNECT TOOLS before servicing and when changing accessories such as blades, bits, cutters, etc.
(4). MAKE SURE that blade tension and blade tacking are properly adjusted.
(5). RE-CHECK blade tension after initial cut with a new blade.
(6). TO RPOLONG BLADE LIFE ALWAYS release blade tension at the end of each workday.
(7). CHECK COOLANT DAILY Low coolant level can cause foaming and high blade temperatures. Dirty coolant

can clog pump, cause crooked. Rust, low cutting rate and permanent blade failure. Dirty coolant can cause the growth
of bacteria with ensuing skin irritation.

(8). WHEN CUTTING MAGNESIUM NEVER use soluble oils or emulsions(oil-water mix) as water will greatly

intensify any accidental magnesium chip fire. See your industrial coolant supplier for specific coolant
recommendations when cutting magnesium.

(9). TO PRNMT corrosion of machined surfaces when a soluble on is used as coolant, pay particular attention to

wiping dry the surfaces where fluid accumulates and does not evaporate quickly, such as between the machine bed and
vise.

F. SPECTIFIED USAGE:

This machine is used only for general metals cutting within the range of cutting capacity.

G. NOISE:

A weighted sound pressure level : under80 dB.

H. SAFETY DEVICE:

Interlock switch on cutting area as soon as the cover of cutting area is open, machine will stop at once witch the
function of this switch. Do not remove this switch from machine for any reason, and check its function frequently.

the swivel head.

2. A tooth selection chart was provided on the machine for cutting reference.

3. Variable speed control gives convenient selection of speeds. (This machine comes with a standard 2-speed

motor. But can be purchased with a DC driven mot or as an opti o n. )

7. MAKE PROPER TOOTH SELECTION

For maximum cutting efficiency and lowest cost
per cut, it is important to select the blade with the right
number of teeth per inch (TPI) for the material being cut.
The material size and shape dictate tooth selection.

TOOTH
SELECTION

You need to consider:
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

1.The shape of the work-piece.

z 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.

z 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.

z Tubing, Pipe, Structural ( 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. (79cm

3"(75 mm ) ID = 7.0 sq.ln. (44cm
