4. NOTES OF CAUSION FOR CHECKING AND REPAIR
In order to avoid secondary damage, please pay attenlion to the
following points;
(I) When assen;bling. M disas.embling tbe machine, always ensure that t he AC
adapter is unplug&>cd from the socket.
(2) Be sure not t o pull the plug by the co•·d when disconoecting it from the
socket.
(3) Tighten nuts and screws down securely.
(4) llc sure not to lose any nuts, screws, or washers, and ensure not to leave any
of them in the machine during a.5i'i.cmhly. These can be the cau.~c nf short~ in
the electrical circuitry.
(5) J)o not damage the cords or PC boards with the soldering iron.
(6) The electrical pans w.;cd in the machine can be damaged hy static electricity.
T herefore, be sure to handle PC boards by the edges and to refrain fro m
allowing your hands to come into direct contact with parts.
(7) When tran.~porting PC boards, it is best to wrap them in aluminum foil or in
~:~n anti static elcctri<.:ity bag. \\'hen transporting the main PC board
assembly. always ensure t hat the lithium battery has been removed. Never
wrap the assembly with the lithium battery still anachcd. Polyethylene and
styrene can cause static electricity and should not be used fo r wrapping.
(8) Alier the completion of assembly or disa.o;sembly. check to en,ure that all
connector.~ a rc properly connected and that the equipment operate.~ normaUy.
(9) "Inc main power should be the same as the rating of the ma~-hine.
( 10) Ensure that the posith•e and negative terminals of the lithium battery arc not
shorted.
(I I) Check the exclusi••e adapter for knitting machine.
Clf it is used different adapter. knitting machine is broken.)

The control PC board is the main control ponion or the equipment. It is
comprised of the microcomputer. nttmory. and voltage regulator. etc.
5.5 Solenoid P C Board
The solenoid PC board is a PC board which is acted upon by the needle
selrttor device. It is connected to the co ntrol PC board assembly by a
connector (P4, P5).
There are 12 needle selector solenoids, with numbers on them, counted
sequentially from left to right. T here are 6 needle selector plates, the
relationship to the rotary cam of which is given in ligore 5-3 below.
5.2 Main P C Board
The main PC board is the keyboard portion. It is comprised the lamp (LED
and 7 segment LED), switch, and solenoid driver, etc.
5.3 Left Position Sensor PC Board and Right Position Sensor PC
Board
The left and right position sensor PC board ar~; what send out the carr,age
position signal. lt is connected to the control PC board by a connector ( P2,
ltvuu )' ~·n• "''le'""'C.
P6).
I
The position sensor signal (pin 3 of P2. P6) is normally DC 1.6 - I.SV, but
when the K carriage sensor magnet approach.,. the position sensor, it
becomes DC 3.SV o r more.

G!Uii::N, and START lamps will be turned off. Then. the ~t ep 2 test will
begin.
*When th...., is a problem
By performing the checks given above, c heck the mounting position of the
position sensor PC board hoti7.0ntally and venically to sec that each have the
proper voltages. If they do not, replace the position sensor PC board.
• Step 2 -This is to check to sec whether, of the needle position de tect circuit
signals, the v,, V;, and iRQ (count edge) signals have been properly
sent lO the computer.
( 10) Move the carriage forward and back ward one time (20 needle-< or more). If
a problem is noted during step 2, an "E" will be displayed in the memo
display, and an e rror digit in the display. When there is an error d igit in the
displar, the
will proceed no funher.
If the STEP key i$ pressed. the step 2 te$t will be repeated.
• Step I -Display right or left position signal voltage. The computer will repon
that it has detected either the K carriage sensor magnet.

Turn the display off by pushing the ICE I key.
Input the digits .:ID ®~and push the STEP I key.
The voljlfj oi the left position signal will be indicated in the d isplay (for
example, J 7 6 indicates 1.76V). A yellow lamp will light, indicating tl\at the
left side is being checked. When there is no carriage sensor magnet in from of
the sensot, a voltage of 1.76V or 1.92V will be indicated. At this point, if the
VR on the left position sensor PC board is turned, the voltage displayed in
the display will also change.
•Note:
In the event t hat the voltage displayed in the di,play does not fall between
1.76V and 1.92V, adjust via the VR on the left pusition sensor PC board.
This adjustment should he done a< follows: first , turn the VR slowly until
1.92V is displayed, then turn it slowly to the left until 1.76V is di~played and
stop.
*Wbeo therr is a problem
When adju8tmcnt cannot be effected, replace the positio n sensor PC board

The condition of the v,,

I: The signal remains High
2: The signal remains Low
and attempt the abo\·e adjustment again.
(5) Place the K carriage sensor magnet in front of the sensor (with the change
knob o n < KC>). At this t ime, the voltage. indicated in the display should be
3.36 V or over. When voltage is 3.tl4V or over and the computer detects th~ K
carriage, a "I" will be di.,played in the memo display.
If the direction of carriage movement changes (from right to left (when the
yellow lamp is on), it will turn oll'. Check the both of sensor magnet.
(6) Push the IGR F. F..NI key.
The voltage of the right position sensor signal will be displayed. The green
lamp will light indicating that the right side is being chec~ed.
(7) Using the sequence given in (4)-(5) above, check the conditions of the K
carriage on the left.
*NOie:
To recheck the left side, pushing the [.yr:Li.OW] key will put the equipment

<I..ongitudinal adjustment of sinker plate>
I. The carriage plate and the sinker plates of thi~ rMdel K H-270 are processed
already properly; therciorc there is no need to readjust them.
2. Mounting dimension of.~inker plate
The standard dimcn~;ions between the carriage rear rail and the sinker plate arc
149 mm on the inside and 148 mm on the outside. When necessary. loosen six
screws of sinker plates on both sides ror propcr adjustment. (See Fig. 10.)

I. Fit the carriage to the needle bed and sec the H .C.L. knob to the posicion H.
2. Put some five plain needles forward to t he point E. o n t hree positions, right,
middle and left of the needle bed.
3. Bend and adjust che sinker plates so thac the clearance between the stems of
plain needle and che sinker ~lates may not exceed 0.5 mm.

13.3 Checking the Needle Selector Mechanism
I, The objectins of check sequence I
First of all. in order to determine. whether the cause of the error in needle
selection is in the needle selection mechanism (the mechanism portion). or in
the electronic portions, move the carriage with the power turned off.
When tbe power is turned off, the solenoids are also all off, all of the rotary
cam levers are on the rotary cams, and the knitting needles should all be
selected to position D.
(!)
Am"""'"'"'".'
With this test, the carriage needle selection mechanism. the ruhhing surfaces
of the needle selection solenoid armature. the rotary cam, the rotary c.am
levers, the N.S.P. operation levers. and the needle selector plate may be
checked.
2.
When tbe test determines that not all of the needles come out to position D,
but that some remain in position R.
(I) When there is no regularity (e.g., 6 pitches. I ~ pitches, etc.) in the needles
remaining in position 8
a. The knitting ne~les are bent.
b. The belt has not been properly mounted to the bevel gear Z32
assembly.
c. The rotary cam has not been properly mounted to the rotary encoder.
d. The card reader guide plate or the bevel gear Z32 assembly position
are out of adjustment.
(2) Wh~ tpe needles remai ning the position B show regularity (6 pitches or
6.,.11-fl @il4;lles)
·.
~herll'e~dle selector plat< is not moving because the rotary cam levers
\z·_ and:N.Ii.L",··operauon levers have not been moun~d properly.
b. The rotar.y cam le\'er is gelling caught on thC Ciud reader guide and:
slipping, do not move. Apply grease.
c. The needle sel«tor solenoid armature and the solenoid yoke are
'------------··
3.
c. The N.S.P. operation lever stay is interfering with needle selector
plate number 6.
r. The needle selector plate springs are loose or are interfering with one
another.
When carriage ope ...tion is much heavy
a. The carriage will not move
The carriage will not move when the rotary cam Jever has come loose from
the face of the rotary cam. When too much pressure is applied to the
rotary c.am \ever, it wlll bend. After checking 10 ensure thac lh¢ rotary earn
lever has not l>ecome bent, adjust th~ positions of the card reader guide
plate and the routry cam.
b. Carriage operation is not smooth
The rotary cam pr~sser collar is making contact with the metal ponion of
the left rotary cam holder bearing. The &ap between the rotary cam and
the rotary cam adjuster collar is too wide.
