WARNING: FAILURE TO FOLLOW THESE RULES

MAY RESULT IN SERIOUS PERSONAL INJURY

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.

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 foot wear 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.

B. USE OF MACHINE:

(1). REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to see that

- 4 -

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 starting cut.
(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 a twoprong receptacle,
the adapter lug must be attached to a known ground. Never remove 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.

- 5 -

E. MAINTENANCE:

(1). DISCONNECT machine from power source when making repairs.

(2). CHECK DAMAGED PARTS. Before further use 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 work day.
(7).CHECK COOLANT DAILY Low coolant level can cause foaming and high blade

temperatures. Dirty or week coolant can clog pump, cause crooked. Cause, 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: under 80 dB.

H. SAFETY DEVICE:

By the time the saw arm cover is opened, the interlock switch will function to stop the
Machine. Do not remove this switch from machine for any reason, and check its function
frequently.

3. MINIMUM ROOM SPACE FOR MACHINE OPERATION

4. 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.

- 8 -

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.

TELLTALE CHIPS

Chips are the best indicator of correct feed force. Monitor chip information and adjust feed
accordingly.

Thin or powdered chips – increase feed rate or reduce band
speed.

Burned heavy chips – reduce feed rate and/or band speed.

Curly silvery and warm chips – optimum feed rate and band
speed.
