(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 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. Can 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 : 80 dB.

H. SAFETY DEVICE:

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

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.

- 7

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
Enter 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 Sollds (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 Vary-Tooth.

 Tubing, Pipe, Structural’s( 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 Vary-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.
