【2】MACHINE SPEED
2-1 Machine speed & direction in which the machine pulley runs
Refer to the table below for maximum and standard
speeds of the Series. To extend machine life, run
the machine approximately 15-20% below the
maximum speed for the first 200 hours of operation
(approx. 1 month). Then run the machine at the
standard speed. The machine pulley turns
clockwise as seen from the end of the machine
pulley.
2-2 Motor & belt
Motor : 3-phase，2-pole，400W clutch motor
Belt : M type V belt
Select the proper motor pulley according to the
machine speed (refer to the motor pulley outer
diameter on the table below). Adjust where to
position the motor by pressing the finger onto the
middle of the belt so that 1~2cm deflection can be
obtained (see the illustration on the right).

【3】LUBRICATION
3-1 Oil
Use Kansai Special’s genuine oil.
(Part No. 28-611)
3-2 Oiling
■To fill the machine with oil
Remove oil plug A from the oil hole.
Fill the machine with oil until the oil level is at the
top line (see H in the illustration) on oil gauge C.
After the first lubrication, add oil so that the oil
level will be between H and L.
■To check for proper oil flow
After filling the machine with oil, run the machine
to check the oil is splashing from oil pipe outlet B.
3-3 Replacing the oil and the filter element
To extend machine life, be sure to replace the oil
after the first 250 hours of operation.
To replace the oil, follow the procedures below.
1. Remove the V belt from the motor pulley and
then remove the machine from the table.
2. Remove screw D and then drain the oil.
Be careful not to stain V belt with the oil.
3. After draining the oil, be sure to tighten screw
D.
4. Fill the machine with oil by referring to 3-2
shown above.
If filter element E is contaminated, proper oiling
may not be performed. Clean the filter element
every six months. If just a little or no oil flows out from the nozzle with the proper
amount of oil in the machine, check the filter element. To clean the filter element,
remove oil reservoir.

4-2 Installing the machine
Install the brackets on the underside of the table board (see the illustration below).
Fit the rubber cushions onto the brackets.
Mount the machine head on the rubber cushions.
【5】TIMING OF THE LOOPER TO THE NEEDLES
5-1 Angle and height for installing the looper
To obtain the proper angle and height,
insert the looper fully into looper holder A
and then tighten screw B.
The proper angle for the looper on HDX is
5°. Distance at 20mm from the point of
the looper between the bottom of the looper
blade and the extension line from the point
of the looper : Approximately 1.75mm.

5-2 Looper left-to-right movement
When the point of the looper moves from the
right/left to the left/right, distance A from the top of
the needle's eye to the point of the looper at the left
side of the needle should be equal (see the
illustration on the right). To make this adjustment,
remove the machine cover, loosen three screws C on
looper eccentric B and then shift looper eccentric B
by turning the machine pulley while holding looper
eccentric B.
5-3 Looper setting distance
When the looper is at the extreme right end of its
travel, adjust distance 5mm from the point of the
looper to the right side of the needle.
Adjustment is made by loosening screw B.
5-4 Needle bar height
When the point of the looper has reached the center
of the needle with the machine pulley turned in the
operating direction, adjust distance 2.5mm from the
top of the needle's eye to the point of the looper on
the back side of the needle. The adjustment is that
raise needle bar up or down by remove rubber caps
A and loosen the screw C.
< Note >
After the above adjustment is made, install the needle
plate and then check to make sure each needle drops
correctly into the center of the each needle drop hole.

5-5 Needle/looper front-to-back relationship
When the looper passes on the back side of the
needle, the clearance between the needle and the
looper should be 0.05~0.1mm.
Adjustment is made by loosening screw A.
To increase the clearance, turn the looper avoid
eccentric toward the back side of the machine.
To decrease the clearance, turn the looper avoid
eccentric toward the front side of the machine.
【6】ADJUSTING THE NEEDLE GUARDS
6-1 Position of the needle guard (rear)
■The position of needle guard (rear) is when the point
of looper located in behind center of needle, the
clearance should be 0~0.1mm is adjusted by screw
A.
6-2 Position of the needle guard (front)
The height of needle guard (front) is when the point
of looper located in behind canter of needle, the
distance should be 1.9mm from top of needle eye till
bottom surface of the needle guard (front) is
adjusted by screw B. The clearance between the
needles and the needle guard (front) should be
0.5mm.
Adjustment is made by loosening screw C.

【7】ADJUSTING THE FEED DOG & STITCH LENGTH
7-1 Feed dog height & tilt
■Height adjustment
The feed dog is at the top of its stroke, the feed dog
teeth should be 2.9mm above the top surface of the
needle plate. Adjustment is made by loosening screw
A.
■Tilt adjustment
When the feed dog is at the top of its stroke, the feed
dog teeth should be parallel with the top surface of the
needle plate. Adjustment is made by loosening screw
B and turning screw C.
7-2 Stitch length
Loosen bolt A (right-hand thread) with a 9.5mm
T-wrench. Then turn screw B. To increase the stitch
length, turn screw B counterclockwise.
To decrease the stitch length, turn screw B clockwise.
【8】ADJUSTING THE PRESSER FOOT
8-1 Presser foot pressure
The presser foot pressure should be as light as possible,
yet be sufficient to feed the fabric and produce uniform
stitches. To increase the presser foot pressure, turn
the adjusting knob clockwise.

8-2 Position of the presser foot & foot lift
Fit the presser foot onto the presser bar so that the
needle can drop correctly to the center of the presser
foot needle drop hole.
■Position of the presser foot
Loosen screw A. Adjust by moving the presser foot
left or right while checking to make sure the needle
drops correctly to the center of the presser foot
needle drop hole.
■Foot lift
The presser foot should be 8.5mm above the top
surface of the needle plate.
Set stopper B at the required position.
Fasten the presser foot lift lever with nut C so that
the lever cannot be lowered.
【9】ADJUSTING THE STITCH FORMATION
9-1 Position of the thread support
When the needle bar is at the bottom of its stroke,
the centers of the eyes on thread eyelet A should be
level with the top surface of thread support B, and A
should be parallel with B.
Height adjustment of thread support B is made by
loosening screw C and moving thread support B up
or down. Moving thread support B up tightens the
needle thread. Moving thread support B down
loosens the needle thread.
