The drive motor of PGF hi-speed knitting machine is applied with the technique of frequency conversion, which allows the stepless speed control even during the operation, for example: while the feeding breaks (finishes), the machine is automatically stopped; while the auto feeding device is used for knitting core fabirc, for both thick or thin core material within the limit, the delivery is uniform; the machine is also stopped automatically while core breaking(finishing) to avoid degrated product. And the braided fabric that is made with PGF hi-speed knitting machine is of higher qualify and more reliable.
PGF hi-speed knitting machine is capable to knit curtain belt, shoe belt, cummerbund of the shapes of column, pipe, and flat, and pipe-shape jacket, and so on.
Various kinds of material are adoptable for PGF hi-speed knitting machine, such as cotton yarn, chemical fibre yarn, silk, soft metal wire, and so on.
PGF hi-speed knitting machine is of the close structure, convenient for operation, highly automatic, quick for adjustment, reliable for operation, of lower noise, of higher efficiency, of better quality and so on.
Before starting the machine, shall check the following items:
1 whether the power pressure is correct;
2 whether the earth device is reliable;
3 whether the motor steering is correct;
4 clean up the table, and other obstructions that affect the operation of the machine;
5 whether the machine oil is qualified (oil model, oil volume);
Once the above items are checked and passed, follow up the below procedures to start the machine:
1 connect the power (power 2 phase 380v)
2 move the switch of electrical box to the point of "ON"(the power supply indicator is on, which means it is powered);
3 press the start button;
4 turn the rotating-setup button clockwise
5 refer to the manual of frequency conversion machine to operation the machine.

If the yarn breaks(finishes) while the machine is working, the breaking indicator is on. Check every yarn cop. If the yarn is broken, pull the end of that yarn towards the finished knitting, and then press the startup button; if the yarn cop is empty, take off that one, and replace it and thread the yarn and pull the end of yarn towards the finished knitting, and then press the startup button. If the core is broken, check the core under the machine body, and pull the end of the core towards the finished one, and then press the button to knit.
To change the speed of the top left gear on the center column can obtain different speed of bound, and different sheer-shape cross points of each length in mm (or named as product density, item no.)
Refer to the below chart and table 1 for details

Contrast table between the bound speed of hi-speed knitting machine and gear       Table 1
(from the left to the right)
Frequency of motor: 60HzZB=30ZC=28
ZA  speed of bound CM/min    number of sheer-shape cross point/CM
Frequency of motor: 60HzZB=30ZC=36
ZA  speed of bound CM/min    number of sheer-shape cross point/CM
Frequency of motor: 60HzZB=30ZC=38
ZA  speed of bound CM/min    number of sheer-shape cross point/CM
Note: While the frequency of motor is not 60HZ, the speed of bound is that the value in the above table times the real work frequency/60, and the sheer-shape cross point is not changed.

For the machine that is being employed, must lubricate its lead, spline ingot groove, and the lubrication volume can not spill over, and it is best to lubricate it just avoiding dry-running. Must add oil on the concave ring of spline shaft, at least two times per eight hours, several drops per time.
The oil that is primarily used on the spline gear box must be replaced completely after one month, and then, is to be supplemented according to oil scale quantity. During the production, decide whether to exchange lubrication (the lubrication used on the machine is 32#) according to the oil status. Shall clean up the float on any parts frequently (do not do it while the machine is running).
VIII,  Precautions for Installation and Assembly & Unassembled
Installation: must put the machine on the rigid ground, and must keep it in level after while installing the rear table board.
Hanging Installation: if this machine is moved after dis-packaged, whether for forklift or crane, the point of strength shall always be set on the lower crosspiece under the holder of the quadrate pipe machine, must not on the table board of the knitting machine.
