2Fig.1.1 illustrates the correct position of jacking while moving the
machine. It is very important when moving the machine. The yarn
carrier rail shall never be used to push the machine since it will distort
the rail.

○
3When connecting the electric power, attention must be paid to the
correct voltage. And make sure the ground-wire connected.
2. Installation
○
1After unpacking and locating the machine in the factory, it must be
leveled carefully with a spirit-level to avoid machine distortion in
running. We recommend the machine to be leveled with rubber peddings
for best result. Remove grease from the polished parts before starting to
operate the machine. About the moving parts must be lubricated
according to the following instruction.
Lubrication points Lubricant Frequency
Carriage ＃10 oil Daily
Carrier rail ＃10 oil Daily
Needle bed ＃10 oil Daily
Driving parts Hi-temp grease Weekly
Table 2.1 Lubrication

2Raise the yarn stand till the end of the tubes is leveled with the base plate,
tighten the screws and connect the plug of stop motion situated at the
left rear end.

3.3 Yarn feeder
The position of carrier is adjusted according to the desired knitting
width, correctly make yarn feeder beside the end working needle by
10 ㎜.The yarn feeder must be in the central position between front
and rear needles, also check its height refer to Fig.3.3.When work
several yarn feeder in knitting, the position of carrier should be
adjusted to make each yarn feeder not be overlapped, it avoids
damage of the parts.The yarn carrier on rail must be adjusted in easy
moving, adjustment refers to Fig.3.4.

4. Clear filter
Filters are equipped in the controller and in the parts of main motor, it
prohibits dust to come inside. Please take out the filter and dust it offen
refer to Fig.4.1.

5. Needle bed
5.1 KH-313 needle bed
KH-313 the structure of front and rear needle bed is the same with
regular needle high butt and low butt.

For the knitting needles in unused you don’t need to dismantle them.
All you have to do is to push them in the unactive position. In Fig.5.2
take out the steel wire firstly, and push to the shown area and replace
the steel wire.
Fig.5.2 Unworked position
5.2 KH-313J&TJ needle bed
The structure of the front and rear needle bed is the same. KH-313J
is with regular needles high butt and low butt. KH-313TJ is with
transfer needles high butt and low butt. They both have one kind of
jacks on front and rear needle beds.
Fig.5.3 The structure of front & rear needle bed
The unused butt needles and jacks you jacks you just push them
down to the unworked position. Of course you must pull out and
back the steel wire A & B for procedure.

6. Cam plate distance
The distance between cam plate and needle bed is maximum 0.15 ㎜,
Fig.6.1 shows how to check and adjust.Please check it by every 3
months, loosen the stepped screw and turn the bearing pin to adjust the

7. Remove carriage
When it becomes necessary to remove the carriage, it can be remove
from the left hand side or the right hand side. The procedures are as
following：
○
1Turn off the power firstly.
○
2Remove the side cover.
○
3Disconnect the two plugs on back of carriage.
○
4Remove the fitting screw and cap bolt on connecting plates as
shown in Fig.7.1.Then pay attention to remove the carriage.
○
5After replacing the carriage, it must be confirmed that the plugs,

8. Fabric take-down system
In principle of the take-down tension strength must be small and
average. The take-down system is controlled by torque motor. There are
two important things to adjust the take-down tension strength.
First method is the two speeds No.1 and No.2 as Fig.8.1 adjust each
with turning knob and set the speed, the tension strength is larger and
the speed is faster. You input the numeric in program to select the speed
you want.
Second method is the roller. Each roller can be adjusted individually.
The pressure of roller gets larger and the speed of fabric take-down gets
faster.
☉To detect fabric falling or wraparound, there is equipped with a
press-off detector in the front of roller and a fabric roll-up detector in
the back of roller. The machine will stop automatically when the fabric
happens fall or wraparound.

9. Racking mechanism
○
1The rear bed can be racked five（5）pitches, the initial position”0”. See
the left selvedge of needle bed, the corresponding position that the
first needle of rear is on the left hand side of the first needle of front.
As shown in Fig.9.1.
○
2In editing instruction you can choose the left racking or the right
racking by one pitch.
Left rear
Left front
○
3In each racking position the rear bed and the front bed must be kept in
correct corresponding relation. You check it with pushing one front
needle to tuck position, the hook of front needle and the knock-bit of
rear bed should be at the same position.

4If there has racking instruction in programming, you must enter the
test mode to rack the needle bed in the set position before you execute
tun, and make sure the racking mechanism is matched your
programming.
☉Needle position of transfer must be at the left –2.5 and at the right
+3.5 of needle bed.
