7. 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.
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.
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.
RoundSolids(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,Structural(Symbol:OH^)
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.

9-9.BLADE AND COOLING SYSTEM
The use of proper cutting fluid is essential to
obtain maximum efficiency from a band saw blade.
The main cause of tooth failure is excessive heat
build-up. This is the reason that cutting fluid is
necessary for long blade life and high cutting rates.
cutting area and blade wheels should be kept
clean at all times.
The rate of coolant flow is controlled by the stop
valve lever (A) (fig 12), which directs the coolant
on to the blade. The lever (A) is shown in the off
position.
9-10.OPERATING AND ADJUSTING VISE
The work-piece is placed between the vise jaws with the

9-13.HYDRAULIC SYSTEM (OPTIONAL FOR 1PH)
A). The hydraulic system on the 1319A consists of a
hydraulic cylinder, which is operated by a needle valve.
The saw frame is raised automatically by the hydraulic
cylinder, and as this is done, oil passes to the underside of
the piston. The feed valve (D) regulates the feed rate
control knob and governs the desent of the saw head. (fig
20) To stop the desent of the head the operator can turn
the stop valve (E).
9-14.GEAR BOX
The gearbox should be drained and refilled after the
first 50 hours of use and thereafter every 5 months,
with Mobil Synthetic Gear Oil, SHC-636, ISO
Viscosity Grade 680. This oil meets or exceeds
American Gear Manufacturers Association (AG.M.A.)
#8 compounded Cylinder Oil specifications. This oil
is available through Grainger's in 1 quart bottles as
number SW061.
To change the gear oil, proceed as follows:
1. Run the machine for 10 minutes to warm up the
gearbox.
2. Raise the saw arm to its maximum position and
close the feed rate control knob.
3. Drain the gearbox by removing the screw away
from the oil-out hole (A) (fig. 21).
4. Replace a screw and lower the saw arm to its
lowest position.

9-16. HOW TO OPERATE HYDRAULIC UNIT (FOR 330A)
1. This hydraulic unit is using (Esso,H15)
oil. Change first oil after 50 hours use.
Then change oil every 6 months after.
2. Run the hydraulic unit for at least 10
minutes before changing oil, this will let
the oil flow smoother and easier to
change.
3. Open the oil outpour door with tool
when changing the oil. Let the used oil
out completely.
4. Close the outpour door firmly, open the
input door (A) and pour in the oil by 3 liter

9-17. HOW TO USING CLEAN EQUIPMENT
When you have finished cutting, you can clean the
chips by using wash down hose. Adjust the screw
(on the end of spray nozzle) to control the volume
of coolant fluid.
Clean the work area floor immediately when
coolant fluid leaks on the floor.
Fig. 24
Always keep the floor around the saw dry to prevent slipping.
10.MAINTAINING
That's easier to keep machine in good condition or best performance by means of
maintaining it at any time than remedy it after it is out of order.
(1) Daily Maintenance (by operator)
(a) Check lubricant before starting the machine everyday.
(b) If the temperature of the spindle begins over-heating or making strange
noises, stop machine immediately to check for damage.
(c) Keep work area clean; clean chips from machine and follow instructions for
lubrication and rust proof oil before leaving.
