3. INSTALLATION

DANGER :

1. The sewing machine should be installed by a trained technician.

2. Contact the distributor or a professional electrician to ask him/her to carry out electric wiring.

3. The sewing machine has a mass of approximately 110 kg. Four or more workers are required to carry out the installation of the sewing machine and adjustment of the table height.

4. Never connect the power plug until the installation of the sewing machine is completed in order to protect against an accident due to an abrupt startup of the sewing machine.

6. Be sure to raise/return the sewing machine from/to its home position by holding it with both

7. Do not apply an unreasonable force to the sewing machine when it is in the raised position. If

• Use the table and stand which are able to withstand the sewing machine mass (110 kg) and vibration. The

• Use the table stand which has an appropriate height for the sake of the operator's ease of use.

1. In the case the table thickness exceeds 60 mm, the length of the bolts supplied with the unit as

accessories is adequate.

In the case the semi-sunken type machine head is used, the kit for semi-sunken type (part number : 40157881)

is required. Prepare the kit simultaneously with the table.

In the case the semi-sunken type machine head is used, the table reinforcing plate (part number:

32080707）(supplied with the kit (part number: 40157881)) has to be installed without exceptions. (Refer to "3-5.(2) ① Installing the table reinforcing plate" p. 11.)

supplied with the unit.

1. Install control box ❶ 30 mm or more away from the stand. If control box ❶ is located too close to the stand, the for-

mer can get hot or the sewing machine can malfunction.

2. In the case the semi-sunken type machine head used, install the control box after carrying out the procedure written

in "3-9. Installing the regulator and the

manifold" p. 20.

3-6. Raising and returning the sewing machine

DANGER :

1. Do not lift the sewing machine for any purpose other than for installation, repair or adjustment in order to prevent accidents resulting in personal injuries due to pinching. In addition, the sewing machine has to be lifted for repair or adjustment only by a maintenance technician

who is familiar with the machine.

2. If you nd the sewing machine is too heavy to lift, the gas spring may have malfunctioned

due to outgassing.

Never lift the sewing machine in such a state since the machine can drop to pinch hands,

ngers and arms resulting in serious injury.

* Carefully read the description given in "10-14. (6) Standard of replacing time of the gas spring"

p.94 and "10-14. (7) Replacing the gas spring" p.95.

3. Be sure to carry out the work while strictly observing the following in order to protect against serious injury to hands, ngers and/or arms due to pinching in the relevant parts of the sewing

machine.

• Be sure to hold the sewing machine by the ribs located on the front side of the bed.

•

Be sure to securely x the sewing machine in the raised position by locking the hinge stopper.

4. Do hole hold any part other than the ribs located on the front side of the bed.

5. If you raise the sewing machine with the feed base remained this side, the feed base can move to pinch hands and ngers resulting in an unexpected injury.

WARNING :

When raising/returning the sewing machine from/to its home position, check to be sure that the sewing machine is locked by the support shaft in the stop position of each step of the hinge stopper.

The sewing machine can be raised/returned to/from four different heights.

side of the bed.

3) Carefully remove at-blade screwdriver ❹. Hold ribs ❶ located on the front side of the bed with

your both hands to slowly lift the sewing machine to the 1st step of hinge stopper ❻.

At this time, do not hold feed base ❷ and feed

guide shaft ❽.

4) Check to be sure that hinge stopper ❻ is locked by support shaft ❼. Then, take hands off the ribs.

5) To raise the sewing machine to the 1st to 3rd steps of the hinge stopper, hold ribs ❶ located on the

10) Take your left hand off the stopper section. While supporting ribs ❶ located on the front side of the bed with your both hands, lower the sewing machine further.

DANGER :

1. Do not lower the sewing machine while keeping pulling the hinge stopper in direction A, in order to prevent pining of ngers, hands and arms under the sewing machine leading to a serious injury. (Be sure to take your hands off the hinge stopper.)

2. Do not hold feed base ❷ and feed guide shaft ❽.

11) At its each step, the hinge stopper is locked to secure the sewing machine at the corresponding height.

Following the procedure described in 9), hold rib ❶ on the front side of the bed with your right hand to slightly lift the sewing machine. Then, hold the handle of the hinge stopper with your left hand to release the lock and slowly lower the sewing machine.

12) The sewing machine is stopped again at the nal step of its lowering for the sake of safety. Following the

procedure described in 9), hold rib ❶ on the front side of the bed with your right hand to slightly lift the sewing machine. Then, hold the handle of the hinge stopper with your left hand to release the lock and slowly lower the sewing machine.

DANGER :

Take care to prevent pinching of hands and ngers between the sewing machine and the bottom cover. It should be strictly prohibited to lower the sewing machine by two or more workers while holding it by any section other than the ribs located on the front side of the bed since it can cause a pinching accident resulting in a serious injury to hands, ngers and/or arms.

[Regulator for cloth trimming knife pressure]

Pull down air pressure regulating knob ❺ of reg-

ulator ❹ for the cloth trimming knife pressure and

turn it to adjust the air pressure to 0.35 MPa. Then,

push up the knob to x it.

(The air pressure of the cloth trimming knife can be

adjusted in the range of 0.2 to 0.4 MPa by means of regulator ❹.)

Regulator ❹ for the cloth trimming knife has

been factory-adjusted to 0.35 MPa. Do not

increase the air pressure unless it is really

necessary. Increased air pressure can cause

a decrease in sharpness of the knife and/or

knife breakage.

After the completion of the respective air pressures
