PROPER GROUNDING
Grounding provides a path of least
resistance for electric current to reduce the
risk of electric shock.
CX119N is for use on a normal 110 volt
circuit. Make sure that the machine is
connected to an outlet having the same
configuration as the plug. If an adaptor plug
is used, it must be attached to the metal
screw of the receptacle. To prevent
electrical hazards, have a qualified
electrician ensure that the line is properly
wired.
The band saw should be wired with a plug
having 3 prongs to fit a 3 prong grounded
receptacle as shown in figure-1. Do not
remove the grounding prong to fit it into a 2
pronged outlet.
Figure-1 110-volt outlet for CX119N
It is strongly recommended not to use
extension cords with your CX119N. Always
try to position your machine close to the
power source so that you do not need to
use extension cords.
If it is necessary to use an extension cord,
make sure the extension cord does not
exceed 50-feet in length and the cord is 14-
gauge to prevent motor damage.
WARNING!
Improper connection of the equipment-
grounding conductor can result in a risk
of electric shock. Check with a qualified
electrician if you are in doubt as to
whether the outlet is properly grounded.

Follow the steps below to assemble your
band saw:
Take the band saw table and put it upside
down on floor and make sure that all the
table bolts shown in the figure are tight.
See figure-2.
Figure-2 Table trunion bolts
Now turn the table up right, and remove the
table pin from the table slot and the table
insert (if already installed) and move the
table in position around the blade guiding
through the table slot. See figure-3.
Figure-3 Assembling the fence
Position the table on the base in such a
way that the bolts under the table extend
through the holes on the base. Thread the
two knobs on the bolts (do not tighten). See
figure-4.
Figure-4 Knobs threaded on the bolts
Position the table on the table stop and the
base so that the table is perpendicular to
the blade. See page 15 for details.
Figure-5 Table sitting on the table stop
Locate the table tilt bracket under the table
and attach it to the band saw using the
bigger lock knob provided. See figure-6.

11
BLADE TRACKING
The blade tracking means where the blade
rides on the upper and lower wheels. It
should always be centered on both wheels.
Although the blade tracking of this band
saw is factory set you should check it again
to make sure that the blade is centered on
the wheels. The misalignment of the blade
can be controlled by adjusting the upper
wheel tilt lock nuts.
Disconnect the machine from power (if
connected) and open the upper wheel
cover. Rotate the upper wheel by hand
slowly and see how the blade rides on the
wheel.
If the blade is not properly aligned and
needs to be adjusted, loosen the lock nuts
shown in figure-11 and turn the knobs.
Figure-11 Knobs and Locks Nuts
TURN KNOBS CLOCKWISE:
If the blade moves towards the front edge
of the wheel. It makes the top of the wheel
to tilt back and moves the blade towards
the center.
TURN KNOBS COUNTER-CLOCKWISE:
If the blade moves towards the back edge
of the wheel. It makes the top of the wheel
to tilt to the front and moves the blade
towards the center.
Figure-12 Blade centered on the wheel
When you have adjusted the blade tracking,
retighten the lock nuts.
Figure-13 Lower wheel adjustment sleeves
IMPORTANT
In very rare cases if the blade tracking is
not adjusted by tilting the upper wheel,
then you will have to make minor
adjustments to the angle of tilt of the
lower wheel. Loosen the four hex bolts
and rotate the sleeves to tilt the lower
wheel to get the proper angle of tilt and
tighten the bolts back. Remember, this
adjustment is done only if the blade
tracking is not adjusted by tilting the
upper wheel.

TEST RUN
Once you have assembled your machine
completely, it is then time for a test run to
make sure that the machine works properly
and is ready for operation.
During the test run if there is any unusual
noise coming from the machine or the
machine vibrates strangely, stop the
machine immediately and disconnect from
the power source and investigate if you can
find out the problem with your machine.
WARNING!
This machine can perform many types of
operations which are beyond the scope
of this manual and are very dangerous if
performed incorrectly. The safety
instructions given in this manual can not
be complete because the environment in
every shop is different. Always consider
safety first as it applies to your individual
working conditions.
WARNING!
Before starting the band saw, make sure
that you have read and understood the
manual and you are familiar with the
functions and safety features on this
machine. Failure to do so may cause
serious personal injury.
IMPORTANT
Make sure you have done the tracking
adjustment and the blade is centered on
the wheels before you start the band saw
for a test run. See page-11

13
BLADE TENSION
A properly tensioned blade is very
important to get the best performance from
any band saw. If the blade is too loose
there is a possibility that the blade will slip
or drift off the line while in operation and it
will be hard to have accuracy in the line of
cut. If the blade is tensioned too tightly, it
will be very difficult to make tighter radius
cuts and there will be a great possibility of
blade breakage.
When using a wider blade for making
straight cuts, for re-sawing or making wide
radius cuts, tighter blade tension is
recommended; while using narrower blades
for cutting shorter stock or making tighter
radius cuts, less blade tension is
recommended.
The information above is just a guideline for
you to understand to set the blade tension
according to the cut however understanding
the blade tension adjustment, comes with
the practice.
Look at the blade tension scale located at
the back of your band saw. The scale
shows the ideal blade tension adjustment
according to the width of the blade.
Figure-15 Quick release blade tension
handle and scale
ADJUSTING BLADE
TENSION
To adjust the blade tension, lift the blade
tension handle shown in figure-15 and turn
it. Turning the handle clockwise will tighten
the tension on the blade while turning the
handle counter-clockwise will loosen the
blade tension.
SUPPORT BEARINGS
ADJUSTMENT
The guide bearings (besides), thrust
bearing (behind) the blade, support the
blade to move in a straight line during
cutting operation. Properly adjusted support
bearings play, an important role in getting
accurate cuts.
To adjust the support bearings, turn the
machine off and disconnect the cord from
the power source.
IMPORTANT
All blades stretch with use, and the scale
at the back of your band saw (shown in
figure-15) is just an approximation. So,
do not reply on any adjusted
measurement for long period of time as
the blades stretch and the tension on the
blades changes.
IMPORTANT
To prolong the life of the blade and
reduce blade stretching, when the
machine is not in use for period of 24
hours or more release the tension on the
blade.

14
Remove the blade guard and use a screw
driver to loosen the screws located on each
of the two guide bearings as shown in
figure-16.
Figure-16 Set screws
Adjust the two guide bearings so that the
space between each bearing and the blade
should be 0.002” which is thickness of a
sheet of paper.
Figure-17 Distance between the guide
bearings and the blade
Now, retighten the screws to lock the guide
bearings in place.
Loosen the thumb screws shown in figure-
18 and move the bearing shafts in or out so
that the two guide bearings are 1/32”
behind the blade teeth and the thrust
bearing (upper bearing), 1/64”.
Figure-18 Distance of the bearings behind
the blade
Once the bearings are at the correct
position behind the blade, tighten the thumb
screws to lock the bearings in place.
Adjust the lower support bearings in the
same manner.
TABLE STOP
ADJUSTMENT
CX119N features a table stop which allows
the table to easily come to a 90° if the table
is tilted.
To adjust the table stop so that the table
sits at 90°, you should first make sure the
switch is in “OFF” position and the power
cord is unplugged. Loosen the two lock
knobs under the table and loosen the hex
nut which locks the table stop bolt.
Now, place a square on the table as shown
in figure-19 and adjust the table stop so that
the table is at a 90° with the blade.

15
Figure-19 Adjusting the table at 90° to the
table using square
Once the table is at 90° with the blade,
tighten the hex nut and the knobs.
TABLE TILT SCALE
CALIBRATION
To calibrate the table tilt scale:
Make sure the table is at 90° and the blade
tensioning and tracking is properly done.
Disconnect the machine from the power
source and loosen the pointer screw shown
in figure-20. Align the tip of the pointer with
the 0” mark on the tilt scale and tighten the
pointer screw.
Figure-20 Table tilt scale
TABLE ALIGNMENT
To make accurate cuts with your band saw,
the table should be aligned properly with
the blade.
TO ALIGN THE TABLE:
Make sure the blade tension and tracking is
done correctly. Disconnect the machine
from the power source and loosen the two
knobs under the table. Place a straightedge
on the table so that the straightedge
touches the blade and is parallel to it as
shown in figure-21. Make sure the
straightedge touches only the flat part of the
blade, not the teeth.
Now, use a ruler to measure the distance
between the miter slot and the straight edge
on both sides on the table R & L. See
figure-21.
Adjust the table until the distance on both
sides of the table is equal and tighten the
knobs.
Figure-21 Aligning the table with the blade
using a straightedge

16
GUIDE POST
The guide post assembly can be moved up
or down above the work-piece. The
movement of the guide post is controlled
with the hand wheel shown in figure-22.
Figure-22 Guide Post
To make accurate cuts and to reduce the
blade slipping out of position, it is
recommended to keep the guide post no
more than 1” above the work-piece while
cutting operation.
TO ADJUST THE BLADE GUIDE
ASSEMBLY:
Make sure the switch is turned off and the
cord is disconnected from the power
source.
Loosen the guide post lock knob on your
band saw shown in figure-22 and rotate the
hand-wheel to move the guide post
assembly up or down.
When the guide post assembly is about 1”
above the work-piece, lock the guide post in
place using the lock knob.
SPEED CHANGE
SETTINGS
CX119N features 3 speed settings; 1430
FPM, 2300FPM and 3250FPM.
The band saw features a motor pulley and
an idler pulley. The motor pulley is a 3-step
pulley while the idler pulley is a 4-step
pulley. The first 3 steps on the idler pulley
are to line up with the motor pulley for 3
feed speeds and the 4th one is to drive the
pulley behind the wheel.
Figure-23 Pulleys, wheel and drive belt
The band saw speed can be changed by
loosening the tension on the driver belt
using the motor bracket lock at the back of
the band saw. Pulling out the lock shown in
figure-24 disengages it for resetting while
releasing it, engages the bolt for tightening
or un-tightening.
TO CHANGE THE SPEED ON THE BAND
SAW:
Open the lower wheel cover and use the
motor bracket lock lever to turn the bolt
counter-clockwise and lift the motor with
hands and tighten back the bolt. The driver
belt will be enough loosen to move it
between the pulleys.

17
Figure-24 Unscrewing the bolt to loosen the
motor bracket
To set the band saw to a speed of
1430FPM, line-up the drive belt on the first
steps of the pulleys. See figure-25.
To set the band saw to a speed of
2300FPM, line-up the drive belt on the
second steps of the pulleys. See figure-25.
To set the band saw to a speed of
3250FPM, line-up the drive belt on the third
steps of the pulleys. See figure-25.

Once you have positioned the drive belt on
the pulleys, turn the motor bracket lock
lever clockwise to lock the motor in place.
WORK-PIECE INSPECTION
Before cutting any wood, make sure to
inspect the work-piece for nails, staples,
small pieces of stone or metal and any
other object which is dangerous to come on
contact with the blade.
If the wood contains any of these objects
and it comes in contact with the blade, the
object might fly and hit the operator or
seriously damage the blade. For a safe
cutting method always inspect your work-
piece carefully before cut and wear eye
protection.
Some woods with excessive twisting or
wrapping are un-stable while cutting and
are dangerous to cut because during
operation the work-piece can move un-
expectedly which either damage the blade
or hurt the operator.
If the wood is slightly cupped, make sure
the cupped face of the wood is held against
the fence. If the bowed side of the work-
piece is held against the fence, the work-
piece will move while cutting.
Some stock with large knots can damage
the blade and wet stock will give a poor
result.
WARNING!
The information above is just a guideline
for you to understand how to cut a work-
piece with slight cupping. If you are not
sure and do not have any experience in
cutting cupped stock, do not cut it.
Failure to follow these instructions might
bring personal injuries to the operator or
serious damage to the blade.

18
CAST IRON WHEELS
The CX119N comes with heavy duty cast
iron wheels for added stability and overall
performance.
A coplanar shim adjustment also added for
better alignment of the wheels that allow
the blade to run as straight as possible
ensuring straight and accurate cuts.
This feature will help improve the band saw
performance with the wheels working
together instead of against each other. The
end result will give you less vibration, more
power, accuracy and less wandering. This
will be noticed most when it comes to re-
sawing and making straight cuts with
blades larger than 1/4”.
COPLANAR ADJUSTMENT
Figure-26 and figure-27 show the shim for
adjusting the top wheel. To move the wheel
out remove the nut and shims then remove
the wheel.
Now you can add shims to the back of the
wheels as required. Replace the wheel and
any remaining shims and the nut and
tighten. To move the wheel in, remove the
cast iron wheel as mentioned above and
remove the shims from behind the wheel.
Replace the wheel, shims and nut and
retighten.
Figure-26 Top wheel front shims
Figure-27 Top wheel back shims

19
OPERATIONS
Before operating the band saw make sure
you have performed the following
adjustments:
Blade tension adjustment
Blade tracking adjustment
Guide bearings adjustment
Make sure all the guards are in place
RIPPING
Cutting solid wood with the grain cutting
down the length of the work-piece is called
ripping.
Adjust the fence on the rails, according to
the width of the cut on the work-piece and
turn the hand-wheel to set the guide post
assembly 1” above the work-piece.
Now, turn the band saw ON and use a push
stick or the band saw finger protector to
push the work-piece against the blade.
CROSSCUTTING
Cutting solid wood across the grain and
cutting plywood across the width of the
work-piece is called crosscutting.
Mark the work-piece where you want to
start the cut from and make sure the miter
gauge is at 90° position on the miter slot.
Place the work-piece on the table so that
the marked point is aligned with the blade
and hold the work-piece against the miter
gauge.
Turn the band saw ON and feed the work-
piece against the blade.
RESAWING
Cutting a work-piece into two or more
thinner pieces is called resawing. Wider
blades give better result, when resawing.
To resaw a work-piece make sure that the
table is at a 90° with the blade and using a
wider blade will give better results.
Adjust the fence according to the width of
the cut you want, and lock it in position.
Turn the band saw ON and feed the work-
piece into the blade using feed paddles until
the blade is completely through the work-
piece.
CUTTING CURVES
For cutting curves always try to use
narrower blades. When cutting curves feed
the stock into the blade and turn it very
carefully so that the blade follows the line of
cut and make sure the blade does not twist.
Make relief cuts through the waste part of
the work-piece which makes the job easier
and prevents the blade from twisting.
WARNING!
Do not use your fingers to feed narrow
work-pieces into the blade. If you slip,
your fingers might come close the blade.
Always use a push stick.

20
CONNECTING TO A DUST
COLLECTOR
CX119N features two 4” diameter dust
ports to connect to a dust collector.
When connecting to a dust collector, use a
proper sized hose and make sure all the
connections are sealed tightly.
Figure-28 CX119N connected to dust

WARNING!
The saw dust produced by the band saw
can go into your lungs and cause serious
health problems. Make sure the band
saw is connected to a dust collection
system while operating it.
