Preparation for Installation
Installation must be carried out by authorized personnel. Follow the steps below:
1. Position the machine on a flat surface and allow at least 50cm clearance on both
sides as well as the back side, this is essential for the hot air ventilation and also
to allow enough room for maintenance personnel to carry out necessary service
and maintenance
2. Adjust the foot stand so that the machine is level and stable.
3. Loosen all packing cable ties and materials in order to free up all machine
movements.
4. Connect the power plug to a suitable outlet with at least 10A capacity. Make sure
grounded and reliable.
5. Locate the air hose supplied with the machine. Connect one end to the inlet of the
compressed air water filter at the back side of the machine; connect the other end
to a compressed air supply such as air compressor or central air supply. Make
sure the compressed air supply has at least 0.4Mpa (4 bar) of pressure.
6. Install the tensioner at the top of the machine and align the tape spool at right
angle to the working table of machine. (see diagram below)
7. Turn on the power,later it will show the languages page.(shown in Figure 1)

Boot test
Check the upper and lower wheel pressure
Adjust the top of the cylinder adjustable screw and lock cover
Press the foot switch of upper and lower mold at the same time
Gradually adjust the distance between the cutter wheel and the lower mold to change
the pressure until you can completely cut the current work piece. (as shown in Figure 4);
A: the role of adjustable cylinder screw: adjust the distance between the upper wheel
and the lower mold, to changing the working pressure;
B: the role of the lock cover: when the knife wheel and the lower mold spacing is
better, tighten the fixed cylinder screw.

The choice and installation of the jet nozzle
1) The choice of jet nozzle: The machine is equipped with two jet nozzle,
according to different functions to choose a different jet nozzle, sticking strip
function is a separate nozzle, overlap, wrapping and hemming is a separate
nozzle.

2) The installation of jet nozzle: Close the hot air adjust (upper) when installing
the jet nozzle, that is tightened clockwise. “hot air indication”displayed as
0Mpa, After fitted with jet nozzle, In the upper wheel press down, the control
center "upper hot air" in the "open" situation, press start stop pedal switch,
the nozzle comes out automatically, the mouthpiece automatically protrudes
you can move nozzle to find the desired location，after confirm the position,
tighten the screws (as shown in Figure 6)

Note: the nearest distance between the gas nozzle and the heat conducting slot is about 1mm, which is
the best distance (as shown in Figure 7).

The use and installation of each function parts
1) sticking strip function: After the adhesive tape is installed, you can
use it directly. It should be noted that when the machine is doing
the sticking process, the temperature of the “upper wheel heating”
of the control center shall be lower than 25% of the adhesive strip
temperature, and at the same time, the “lower hot air” temperature
switch shall be switched off. Example: strip the actual temperature
is 120 centigrade. The down wheel heating temperature should be
about 90 degrees Celsius (as shown in Figure 8).

2) folding function：This function is used for cuffs and so on，Arc、
straight and curved edges. adjust the position between it and the
lower wheel before installing the folding brink frame，and tighten
the retaining screws(as shown in Figure 9).
Fig.9
3) overlap function: This can be applied to overlap between two
pieces of workpieces. Install the overlap device according to the
picture, when you install, you can move the baffle，the width
required to reach the overlapping cloth(as shown in Figure 10).

4) wrapping function: This function is suitable for all kinds of cloth
single-fold wrapping operation. adjust the position between it and
the lower wheel before installing the pack brink frame，and tighten
the retaining screws(as shown in Figure 11).
Fig.11
Note：In the use of folding, overlapping, wrapping function，The reading of the "hot air indication
(lower)" table of the control panel must be less than the "hot air indication (upper)" reading, which can
be achieved by adjusting the "hot air adjustment (upper)" and "hot air adjustment (bottom)"
Belt inspection
1) As shown figure 12, tightening tension can be adjusted by
adjusting the tension regulator (1) and tension adjuster (2) angle to
achieve.

The role of the foot pedal(as shown Figure 14)
1. Up / Down: The upper wheel is down or up. Press down one
time and press again;
2. Start / stop: The action of the upper and lower wheels and the
blowing start and stop. Press and hold, release is stopped;
3. Up and down: in the work to be a small turn when the rapid
micro-beating up and down, making the turn more smooth
4. Folding: in the heel began to fix the pieces, the end of the arc
and through the thick bone position is the telescopic effect. Press
once to stretch, press again to shrink.

Control panel instructions (as shown in Figure 15)
1) Hot air indication (upper):Upper blowing air volume display. At the
same temperature setting, the greater the air flow, the higher the
actual temperature；
2) Hot air adjust (upper): Adjust the air volume of the upper blow.
Clockwise rotation of the air flow becomes smaller, counterclockwise
rotation of the air flow becomes larger；
3) Hot air indication (lower):Lower blowing air volume display. At the
same temperature setting, the greater the air flow, the higher the
actual temperature；
4) Hot air adjust (lower):Adjust the air volume of the lower blow.
Clockwise rotation of the air flow becomes smaller, counterclockwise
rotation of the air flow becomes larger.
5) Pressure indication:The pressure between the upper and lower
wheels is indicated.
6) Pressure adjust:When the distance between the upper and lower
wheels is fixed.The upper and lower wheels pressure between the
calibration.

Boot steps
Adjust the temperature, pressure, speed, hot air volume required for
the workpiece. In general, the speed ratio of the upper and lower
wheels is 1: 1.2（as shown in figure16-1）.When the hemming,
overlapping, wrapping, the upper and lower wheel speed should be
consistent (as shown in Figure 16-2).
Foot press down the foot switch, the upper wheel press down.
Foot press the foot switch, the upper wheel up.
Note: Stop working for a long time, the upper wheel should remain
suspended

Maintain
Preventative
In order to keep the machine in top running condition, regular maintenance is
important for trouble free operation. This will minimize possible down time and to prolong
machine life.
Check the tightness of the upper and lower wheel timing belt every 3
months, adjust the internal timing belt tension wheel can change the
tightness of the belt;
Always clean the upper and lower wheels and machine;
Pay attention to the heating time, such as heating time becomes long,
you need to check the heater is normal.
