i
For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the SAFETY PRECAUTIONS includes items which
are not contained in the speci¿cations of your product.
The risk indications are classi¿ed into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.

18. ADJUSTING THE FEED MECHANISM
WARNING :
To avoid possible personal injury due to abrupt start of the machine, turn off the power to the machine and check to be sure that the
motor has totally stopped rotating in prior.
1) Use the 3-phase 400 W AC clutch motor.
2) Use an M type V belt.
3) The following table shows the relationship among the motor pulley and the sewing speed.
Model Sewing speed Effective diameter of
handwheel
Number
of poles Frequency Rotational speed
of motor
Effective diameter
of motor pulley
LZH-1290 2,000 sti/min φ67.4 4 50 Hz 1,430 rpm φ95
60 Hz 1,715 rpm φ80
(Caution) The effective diameter of the motor pulley is obtained by subtracting 5 mm from the outside diameter.

Precautions to be taken so as to use the LZH-1290 more safely
1. To ensure safety, never operate the machine with the ground wire for the power
supply removed.
2. When inserting/removing the power plug, the power switch has to be turned OFF in
advance.
3. In time of thunder and lightening, stop your work and disconnect the power plug
from the receptacle so as to ensure safety.
4. If the machine is suddenly moved from a cold place to a warm place, dew
condensation may be observed. In this case, turn ON the power to the machine
after you have confirmed that there is no danger of water drops in the machine.
5. To prevent fires, periodically draw out the power plug from the plug socket and
clean the root of the pins and the space between pins.
6. The hook rotates at a high speed while the machine is in operation.
To prevent possible injury to hands, be sure to keep your hands away from the
vicinity of the hook during operation. In addition, be sure to turn OFF the power to
the machine when replacing the bobbin.
7. To avoid possible accidents due to abrupt start of the machine, be sure to turn OFF
the power to the machine.
8. Be careful of handling this product so as not to pour water or oil, shock by
dropping, and the like since this product is a precision instrument.
9. When tilting or returning the sewing machine to the home position, hold the upper
side of the machine head with both hands and perform the work quietly so that
fingers or the like are not caught in the machine.
CAUTION :
Note that safety devices such as “eye guard”, “finger guard”, etc. may be omitted from the
illustrations in this Instruction Manual for easy explanation.
When operating the machine, be sure not to remove these safety devices.
1. Keep your hands away from needle when you turn ON the power switch or while
the machine is in operation.
2. Do not put your fingers into the thread take-up cover while the machine is
operating.
3. Turn OFF the power switch when tilting the machine head, or removing the belt
cover or the V belts.
4. During operation, be careful not to allow your or any other person’s head, hands
or clothes to come close to the handwheel, V belt and motor. Also, do not place
anything close to them.
5. Do not operate your machine with the belt cover and finger guard removed.
6. When tilting the machine head, be sure to confirm that the head support bar is
properly attached to your machine head, and be careful not to allow your fingers or
the like to be pinched in the machine head.

Precautions to be taken so as to use the LZH-1290 more safely
1. To ensure safety, never operate the machine with the ground wire for the power
supply removed.
2. When inserting/removing the power plug, the power switch has to be turned OFF in
advance.
3. In time of thunder and lightening, stop your work and disconnect the power plug
from the receptacle so as to ensure safety.
4. If the machine is suddenly moved from a cold place to a warm place, dew
condensation may be observed. In this case, turn ON the power to the machine
after you have confirmed that there is no danger of water drops in the machine.
5. To prevent fires, periodically draw out the power plug from the plug socket and
clean the root of the pins and the space between pins.
6. The hook rotates at a high speed while the machine is in operation.
To prevent possible injury to hands, be sure to keep your hands away from the
vicinity of the hook during operation. In addition, be sure to turn OFF the power to

1. Keep your hands away from needle when you turn ON the power switch or while
the machine is in operation.
2. Do not put your fingers into the thread take-up cover while the machine is
operating.
3. Turn OFF the power switch when tilting the machine head, or removing the belt
cover or the V belts.
4. During operation, be careful not to allow your or any other person’s head, hands
or clothes to come close to the handwheel, V belt and motor. Also, do not place
anything close to them.
5. Do not operate your machine with the belt cover and finger guard removed.
6. When tilting the machine head, be sure to confirm that the head support bar is
properly attached to your machine head, and be careful not to allow your fingers or

18. ADJUSTING THE FEED MECHANISM
WARNING :
To avoid possible personal injury due to abrupt start of the machine, turn off the power to the machine and check to be sure that the
motor has totally stopped rotating in prior.
1) Use the 3-phase 400 W AC clutch motor.
2) Use an M type V belt.
3) The following table shows the relationship among the motor pulley and the sewing speed.
Model Sewing speed Effective diameter of
handwheel
Number
of poles Frequency Rotational speed
of motor
Effective diameter
of motor pulley
LZH-1290 2,000 sti/min φ67.4 4 50 Hz 1,430 rpm φ95
60 Hz 1,715 rpm φ80
(Caution) The effective diameter of the motor pulley is obtained by subtracting 5 mm from the outside diameter.

For the sewing machine, automatic machine and ancillary devices (hereinafter collectively referred to as
"machine"), it is inevitable to conduct sewing work near moving parts of the machine. This means that there
is always a possibility of unintentionally coming in contact with the moving parts. Operators who actually
operate the machine and maintenance personnel who are involved in maintenance and repair of the machine
are strongly recommended to carefully read to fully understand the following SAFETY PRECAUTIONS
before using/maintaining the machine. The content of the SAFETY PRECAUTIONS includes items which
are not contained in the speci¿cations of your product.
The risk indications are classi¿ed into the following three different categories to help understand the meaning
of the labels. Be sure to fully understand the following description and strictly observe the instructions.
