Thank you for purchasing the Model AZ8060G/AZ8560G. This instruction manual provides information on the floating presser foot.

Before using your AZ8060G/AZ8560G, please read the instruction manual together with that for the AZ8000G/AZ8500G and well understand the contents of both documents.

After reading the instruction manual, please store it in a location where it is easily accessible to the operator.

1. Introduction to Model with Floating Presser Foot

1. Features

● The presser foot slides back and forth in conjunction with the vertical and reciprocative movement of the lower feed dog. This mechanism minimizes the twist and deviation of the fabric to be sewn, providing the fabric with a flat, beautiful finish.
● The pressing pressure applied to the fabric to be sewn is decreased, minimizing the bad effect over the fabric.

2. Differences from AZ8000G/AZ8500G

CAUTION

The maximum sewing speed and presser foot lift are different between the model with floating presser foot (AZ8060G/AZ8560G) and the Model AZ8000G/AZ8500G (see the table given on the right side).

3. Motor Pulley

In order to achieve the maximum performance of the model with floating presser foot, the maximum sewing speed must be lower than that of the AZ8000G/AZ8500G. This will require changing the motor pulley used. Select the best suited motor pulley from the table provided on right side.

CAUTION

Use a motor pulley applicable for the AZ8060G/AZ8560G. Otherwise, the maximum speed will be exceeded and your sewing machine may malfunction.

Model	AZ8060G class	AZ8560G class
Max. sewing speed	7000 r.p.m	6500 r.p.m
Presser foot rise	5 mm max.	5 mm max.

List of motor pulleys

Outer dia. of motor pulley (mm)	Sewing machine speed (r.p.m.)
	For 50 Hz	For 60 Hz
90		6000
95		6400
100		6700
110	6200
115	6500
120	6700

The sewing machine speeds shown in the above table are the values that are obtained when a clutch motor for power supply of 3 phases, 2 polarities, and 400 W is used.
* The outer diameters of commercially available pulleys are in units of 5 mm. Therefore, the above table lists the motor pulleys that have the outer diameters closest to those of the commercially available ones.

2. Assembling the Floating Presser Foot

To replace the presser arm and presser foot, C. set for the AZ8000G/AZ8500G with the floating presser foot, perform the following steps:

1. Components for floating presser foot

Check the parts with the table given on the right side before assembling the floating presser foot.

Part name	Q'ty
Floating presser arm, C. set	1
Presser foot, C. set	1
Presser foot release lever stop	1
Screw	1

2. Assembling the floating presser foot

CAUTION

Before starting these steps, be sure to turn OFF the power and then check that the motor rotation stops.

1. Remove the belt from the pulley.
2. Manually rotate the pulley for the sewing machine to position the feed dog lower than the upper surface of the stitch plate.
3. Remove the stopper screw for the presser foot release lever.
4. Tighten the screw for the lever stop as illustrated right.

1. Release the lever and open the presser arm.

1. Remove the presser arm and the presser foot, C. set from the presser foot shaft.

1. Connect the floating presser arm, C. set to the presser foot shaft.

1. Adjust the clearance between the top of the lock nut and that of the adjusting screw at 24 mm. (See Page 6 for adjusting this clearance.)

1. Insert the presser foot, C. set to the floating presser arm, C. set.

1. Install the floating presser arm back in place.
2. Align the needle drop of the presser foot, C. set with that of the stitch plate, and then tighten the lock screw for the presser foot, C. set.

CAUTION

In aligning the needle drop of the presser foot, C. set with that of the stitch plate, adjust the bottom of the presser foot to be in parallel with the stitch plate.

3. Adjustment after Installation

1. Check that the feed dog is positioned lower than the upper surface of the stitch plate.
2. Check that the lever makes contact with the presser foot pin.
3. Check that the needle drop of the presser foot, C. set aligns with that of the stitch plate. (front/rear, right/left and parallel position)
4. Check that the clearance between the top of the groove on the presser arm stop and that of the floating presser arm, C. set stop is between 0.5 and 1 mm. To adjust the clearance, change the position of the lever stop.

Lever stopper positions and clearance changes (the clearance increases in the order of left to right)

1. Loosen the lock nut for the stopper screw on the presser foot shaft lever, and the screw for the presser arm stop.

1. Depress the presser release lever, and then insert something of 5 mm in thickness between the top of the stitch plate and the bottom of the presser foot, such that they are in parallel with one another.

①When the release lever is depressed, the floating presser arm, C. set will be positioned as illustrated.
②When something of 5 mm in thickness is inserted between the top of the stitch plate and the bottom of the presser foot, the floating presser arm, C. set will be positioned as illustrated.

1. Let the stopper screw make contact with the shaft lever when the presser arm and floating presser arm are positioned as illustrated in ②, and then tighten the lock nut.

1. Let the presser arm stop make contact with the presser arm, and then tighten the screw.
2. Remove the thing that has been inserted between the top of the stitch plate and the bottom of the presser foot.
3. Manually rotate the pulley for the sewing machine, and check that the presser rod does not move vertically. If the presser rod moves, tighten the adjusting screw until the presser rod no longer moves vertically. (For the adjusting procedure, see P. 6.)

1. Stretch the belt between the sewing machine and motor pulley.
2. Activate the sewing machine and check that the presser foot functions properly. If the presser foot does not function properly, adjust the presser foot adjusting spring. (For the adjusting procedure, see P. 6.)
3. Check that the presser arm remains stationary when the leading edge of the presser foot is lifted with a finger.

3. Troubleshooting

1. Troubleshooting

CAUTION

Before starting these steps, be sure to turn OFF the motor and then check that the motor rotation stops.

Trouble	Corrective action
● Idling noises are too loud.	Adjust the position of the adjusting screw for the presser foot by 90°.(See “3. Adjustment the presser foot adjusting spring”)
● The fabric is not fed straight.	Perform the steps 10 to 13 under “Adjustment after Installation.”
● The fabric is not fed properly.	Perform the steps 10 to 13 under “Adjustment after Installation.”
● The fabric deviates greatly.	Perform the steps 10 to 13 under “Adjustment after Installation.”
● The fabric is often flawed during feed.	Perform the steps 10 to 13 under “Adjustment after Installation.”

2. Adjusting the presser foot spring

Loosen the lock nut and then adjust the presser foot spring by turning the adjusting screw. To check the adjusted state or measure any dimension, tighten the lock nut in advance.

3. Adjusting the presser foot adjusting spring

Adjust the position of the presser foot spring in a range between 60° and 90°. (The presser foot spring was adjusted in the position of 60° at factory.)

1. Depress the presser foot release lever and open the presser arm.
2. Loosen the lock screw for the presser foot adjusting spring using a slotted screwdriver, adjust the position of the adjusting spring, and then tighten the lock screw.
3. After finishing the adjustment, install the presser arm back in place and check that it remains stationary when the leading edge of the presser foot is lifted with a finger.
