INSTALLATION
These processes are normally completely by a trained technician and should be completed before
you purchase your machine. In some unique cases, you may have purchased your machine
“unassembled” and you will need to follow these steps to prepare your machine for sewing.
1. With two people, lift your Titan TN-1341 onto the tabletop and align the machine into its
correct position.
2. Fix the machine in place using the (4) countersunk bolt (Fig 1, Item 1), washers (Item 2) and
nuts (Item 3).
3. Securely tighten these bolts and nuts before operating the machine.
Figure 1

6 TN-1341 INSTRUCTION MANUAL
INSTALLATION (Con’t)
The Titan TN-1341 comes with a knee lifter unit that allows the operator to lift the presser foot with
a knee controller. This is a standard feature but can be changed to a pneumatic lifter as an option
(See option page). To mount the knee lifter, follow the instructions below.
1. Attach knee lifter plate rod (Fig 2, Item 5) and knee press plate cover (Fig 2, Item 6) to knee
lifter plate rod bracket (Fig 2, Item 4)
2. Align the direction of the pad with setscrews (Fig 2, Item 7, 8 and 9) to the operator’s
comfort.
3. Be sure to note thee travel of the knee lifter can be large and may require an additional
person to find a perfect comfort for the operator.

7 TN-1341 INSTRUCTION MANUAL
BELT AND BELT COVER
The TN-1341 is typically equipped with a 750W servo motor and while there are options for this on
the Options page (needle positioner, speed reducer, etc.), the basic set up for the TN-1341 will be
as follows:
1. Adjust the belt tension with the height of the motor so that the belt sags 15 mm when the
center of V belt is applied with a 9.8 N load.
2. Please note, that if the motor belt is too tight, the machine may labour thru stitching and
cause the motor to have errors. If the belt is too loose, you will have slipage as you sew
and this can also cause motor errors, especially if you have the needle positioning encoder
attached to the machine.

2. Fix belt cover (right) (Fig 4, Item 1)
on the arm with screws 2 and 8.
3. Fit belt cover (left) (Fig 4, Item 3) to
notch A and B of the belt cover
(right).
4. Fix belt cover (left) (Fig 4, Item 3)
with screws 4, 5 and 6.

THREAD STAND
The thread stand is often very simple to assemble but there are a few common issues to pay
attention to.
1. Assemble the thread stand as shown in figure 5.
2. Pay close attention to ensure all screws and nuts
are tightened firmly.
3. Once the thread stand is assembled, it is
important to note that the upper arm of the thread
guide (Fig 5, Item A) is aligned directly above the lower
arm (Fig 5, Item B). failure to align these may cause
tension issues, thread breakages and / or other
machine issues due to poor threading.
4. To install the thread stand into the table,
separate the washers on the base of the stand so that
there is one washer on the top and one on the bottom
of the table. Then install the lock washer and nut on
the base of the stand and tighten until the thread stand
no longer floats loose and freely.

LUBRICATION
It is important to remember that Titan Sewing Machines are produced using some of the highest
quality components and assembled and tested thoroughly to ensure the machines can handle
factory operation day in and day out from multiple operators and shifts. Noting that, you may
choose to alter your lubrication requirements based on the amount of use you are putting your
machine through. If you do not use your machine for an extended amount of time, you should
consider oiling your machine before you put it away and after, when you first take it out to ensure
the machine is properly lubricated before use. The TN-1341 has (3) major components to its
lubrication portion of the machine. They are: The face plate head unit, the upper body and the
shuttle arm area.
LUBRICATING THE FACE PLATE HEAD UNIT
1. Loosen and remove screw A.
2. Open the face plate in the direction
of arrow mark B.
3. Apply an adequate amount of oil
once a day to the points marked with
the arrow marks.
NOTE: you may notice certain areas of
your machine may have grease on
components. If there is grease on any
of the areas that should be oiled or
lubricated, please do NOT oil this. If
you place oil on to a greased area, this
will cause the oil to break down the
grease and it will liquify and could
cause this to drip onto your project
area.
4. Close the face plate.
5. Tighten and attach screw A.
Figure 6

11 TN-1341 INSTRUCTION MANUAL
LUBRICATION(con’t)
LUBRICATING THE UPPER BODY
Apply an adequate amount of oil once a day to the points marked with the arrow marks.
Before you operate your machine for the first time, or after an extended period of disuse, apply an
adequate amount of oil to the points marked with the arrow marks (Fig 7, Item 1, 2 and 3) and to
each felt and oil wick thru the oil wicking system.
A and B are oil reservoirs. Be sure to add oil to the oil reservoir approximately once a week.
Figure 7

12 TN-1341 INSTRUCTION MANUAL
LUBRICATING THE SHUTTLE ARM AREA
Apply an adequate amount of oil once a day to the points marked with the arrow marks.
Before you operate your machine for the first time, or after an extended period of disuse, apply an
adequate amount of oil to the points marked with the arrow marks (Fig 8, Item 4 and 5, Fig 9, Item
6 and 7)
Notes on lubrication:
•Always ensure to use virgin mineral oil on your Titan Sewing Machine
•While under oiling your machine can cause damage to your machine, over oiling can be an
issue to your sewing as well. If your machine is dripping oil onto your sewing project,
consider reducing the amount and/or frequency of oiling to your machine.
•Do NOT reuse this oil, but please ensure you dispose of this oil in an environmentally
friendly way. Most municipalities have Eco-friendly locations that can help you dispose of
this waste oil correctly.

NEEDLES AND THREAD
Like all sewing machines, Titan sewing machines work best when you work with not only the
correct needle for the project and thread, but when you work within recommended guidelines of
use when it comes to needles. Use the chart below to ensure you are matching the correct needle
size to your threads. Remember this is a guideline provided for most common threads. If you are
using specialty threads, your thread supplier should be able to offer you information on what
needle is appropriate for that thread. Failure to do so can cause breaking threads, breaking needles
and in some case damage to your project and/or machine.

*While most suppliers have now changed over to the TEX numbering system for their threads,
some still sell under the old commercial sizing system (CBB) and/or Denier.
•TEX is one of the easiest ways to read and understand thread. The TEX number is the
weight, in grams of 1000 meters of that thread. Example: TEX 70 means that 1000 meters
of that thread weights 70 grams. One slight disadvantage of this system is that different
thread types will weigh more or less than others and can give operators a false sense of the
real strength of different threads.
•Commercial sizes are determined by the threads denier divided by 10. This can be
complicated by threads that are produced of how many strands make up a particular style
of thread, the composition, and other factors. (This is often found in older styles of thread
and unique threads that may be produced today)
•Denier is like TEX in the fact that it is determined by the weight of the thread, in grams, but
of 9,000 meters of thread. This system in more commonly used in Asia and some areas in
Europe but as you can tell, it can be more difficult to calculate strength because it can be
complicated by how many plies of thread are wrapped in any particular thread (excluding
monofilament threads)

14 TN-1341 INSTRUCTION MANUAL
THE NEEDLE
Industrial sewing machine needles are made up of several parts of the needle and knowledge of
these key areas is helpful when you wish to produce a top-quality finished product.
•Scarf – This could be considered one of the most important parts of the needle. This is the
indent that allows the hook to pick up the thread off the needle and form the stitch
•Groove – The groove is the path that the thread will lay in as the stitch is formed. Without
this, the formation of the stitch is compromised
•Blade – This is the part of the needle where the size is measured from. On every needle
there are (2) numbers that determine the size of that needle. The first number is a metric
number and the second is imperial. (Example: 110/18 means that it is 1.10 mm is diameter
at the blade of the needle)
•Point – The point is the first part that enters the material and can be a regular tip, a cutting
tip (for leathers), or a specialty tip (IE. Ball point)
•Eye – The eye is what transports the thread down into the machine. This is where the most
significant wear happens.
•Butt- The butt is the part of the needle that pushes up into the machine and must be fully
engaged into the needle clamp of the machine.
•NOTE: Change your needles often. Manufacturers of needles rate the lifespan of a sewing
machine between 6~8 hours of use. Anything longer and the needle starts to significantly
deteriorate and can cause serious issues with your machine and project. Not only that,
but damage to your machine can be particularly bothersome considering the replacement
price of the needles far outweighs the replacement parts on you machine and/or service
related to this.
Figure 10

15 TN-1341 INSTRUCTION MANUAL
CHANGING THE NEEDLE
1. Turn the handwheel to bring the needle bar to the highest position of its stroke.
2. Loosen needle clamp screw (Fig 11, Item 2) and hold needle so that the long groove in the
needle is facing exactly to the left. This means the scarf should be facing the inside of the
machine body.
3. Push needle as far into the needle bar (upwards) into the needle clamp hole until it will go
no further.
4. Tighten needle clamp screw firmly.
Notes on changing the needle:
•It is recommended to only loosen the needle screw. Removing the needle screw
completely can increase the chance that the screw can be reinserted incorrectly and
cross threading the needle bar.
•If your machine skips stitches, or any other inconsistency, change the needle.
Damage to needles can be hard to see and are not always obvious. Changing the
needle is a great habit when trying to resolve issues.
Figure 11

16 TN-1341 INSTRUCTION MANUAL
BOBBIN WINDING
Before you wind your first bobbin, you
will need to set up the thread guide for
the bobbin winder.
1. Attach bobbin winder thread
guide 1 to the top cover using
screws (Fig 12, Item 2). Pay
close attention to the two
screws. They are used to adjust
the bobbin winding (see below)
WINDING A BOBBIN
1. If your machine has a thread guide pin, pass the thread in the order of 1, through 4.
2. Pass the thread thru one of the holes on the bobbin from inside out.
3. Engage bobbin winder lever A.
4. TO ADJUST THE CAPACITY OF THE BOBBIN: Loosen set screw B and adjust the position of the
adjusting plate to wind a
bobbin about 80~90 % of
its capacity.
5. If the bobbin is wound
unevenly, correct it by
loosening the bobbin
winder thread guide
screws (Fig 13, Items D)
and moving the guide
back and forth to
balance the thread on
the bobbin.
6. Then, tighten set screws
D.
7. When the bobbin is filled
up, the bobbin winder
lever automatically releases the bobbin, and the bobbin winder stops.
Figure 12

17 TN-1341 INSTRUCTION MANUAL
THREADING THE BOBBIN
Threading the bobbin correctly ensures that you will have consistent stitching and end up with a
premium quality product. The Titan TN-1341 machine came with 2 versions of a vertical axis
shuttle. The first is a capless shuttle that and the second is a shuttle with a cap. Depending on
which your machine has, use the following instructions for threading the bobbin.
BOBBIN CAP STYLE
1. Hold a bobbin so that the end of the thread wound
round the bobbin is directed to the right (clockwise) and put it
into the bobbin case.
2. Pass the thread into the threading slit (Fig 14, Item 3) in
the bobbin case, then route it under the tension spring and
draw it out from notch �.
LATCH STYLE
Figure 14
1. Pass the thread into the threading slit (Fig
15, Item 1) in the inner hook, pass under
protruding section (Item 2) and route it to
the tension spring.
2. Adjust the bobbin so that it rotates in the
direction of arrow mark when the bobbin
thread is pulled.
Figure 15

18 TN-1341 INSTRUCTION MANUAL
THREADING THE UPPER THREAD
The TN-1341 is equipped with a dual tension unit which allows the machine to not only expand the
range of threads the machine can handle, but also offers the operator to have more control over
thread tensions.
The first thread guide on the machine is important for one simple reason. It controls the threads
and ensures that no mater what thread you are using, it will stay comfortably in the tension units.
1. For common threads, it is only necessary to thread this guide through any two holes on this
guide.
2. The curlier or twisted the thread is, it is important to thread through more of the holes in
the guide like in the picture.
3. Pay attention to certain threads
(traditionally heavier threads) that should
not go through all the holes on this guide.
Doing so will increase the thread tension
and can cause issues.
4. Follow the thread path as shown in Fig 17
in order.
5. Pay close attention to make sure the
thread passes through each tension unit
and between the tension discs.
Figure 16
Figure 17

19 TN-1341 INSTRUCTION MANUAL
THREADING THE UPPER THREAD(Con’t)
6. Ensure the thread follows the path provided in Fig 18. Pay close attention to the thread
guide (Fig 18, Item 13) that is just above the needle. This is commonly overlooked and can
cause errors in sewing if not threaded.
Figure 18

20 TN-1341 INSTRUCTION MANUAL
THREADING WITH THINNER THREADS
•If you are threading your machine with thinner
threads, it is not necessary to thread through
both thread tension discs.
•In this case, thread your machine as seen in Fig
19 and skip the second tension unit (Fig 19,
Item 6)
Notes on Threading:
•Note that when the presser foot is lifted, the
tensions release from the thread. It can be
easier for an inexperienced user to often lift
the foot when threading to make sure the tension discs open to accept the threads.
•Once the machine is threaded but before you thread the needle, a good habit to follow is
simply pull the threads to ensure there is no tight points or thread incorrectly threaded that
can cause the thread undue stress.
Figure 19
