General
Description
The light and compact des0ign allows easy transportation and op-
eration in a very small space.
A single motor powers these models assuring stable operation
even if the voltage drops.
Strap widths to 6-15.5 mm can be easily adjusted by loosening
only two screws. Different strap guides are available to allow use
of 6-15.5 mm strap widths.
The cams, feeding and tensioning systems are designed to elimi-
nate strap splitting, bending and scratching.
The narrow sealing head allows strapping of irregular and cylin-
drical goods.
Automatic re-feeding of the strap. The operator needs only to
place the strap around the goods and insert into the slot. No train-
ing is required.
These models require only the most basic maintenance. Electrical
and mechanical components are designed for easy replacement.

Operating
Turn the timer knob to determine the length of strapping supplied for next cycle. Timer graduations
are provided from 0 to 5 seconds. The length of strap fed out in one second is approx. 1 meter.
Place a package on the top of the machine, and pass the free end around the package; insert the
leading end of the strapping into the strapping inlet until the leading end is detected.
Weld cooling time
Weld cooling time adjustable; the cooling delay time can be adjusted from 0~1.2 sets, delay time
will be longer by turning VR clockwise.
Tightening of strapping starts as soon as the strap is detected and the heat sealing process automati-
cally takes place after completion of tightening. After these processes have been completed, a preset
length of the strapping is dispensed automatically. This is one complete cycle.
After cycle is completed, motor will turn off automatically if strapping cycle is not initiated within
30 seconds.
Attention:
Be sure to turn off the main power switch after operation is completed for the day.

Maintenance
1. General
Keep the machine clean and neat at all times
The sealer housing assembly should be blown out weekly.
Attention:
Pullout the plug before removing any enclosures for mainte-
nance or service.
2. Lubrication
Apply a few drops of light lubricant (Daphne Mechanic oil or equivalent) to oil holes and on sliding
parts (see the diagram above) once per week.
Change the oil of the gearbox once per year. 150 ml of Daphne oil or its equivalent should be used.
3. Replacing the fuse
Remove the top plate of the machine and the fuse
from the fuse box located near relays. Replace the
faulty fuse with new one.

Troubleshooting
1. The strap will not feed out
1. Turn the motor switch OFF.
2. Strongly pull the strap out in the tightening direction.
2. Strap is buckled and jammed
Remedy:
1. Remove hexagon nut (1), spring washer (2) and flat washer (3).
2. Remove set screw M4 (4).
3. Remove feed roller shaft (5). Remove front-end adjusts plate.
4. Lift the front of shaft holder (6) by about 24 mm.
Pull out the jammed strap and cut it off below the buckled section. Clean the whole section.
Re-assemble in the following order 2,1,3.
3.Strap is jammed between the roller and the guide
Remedy:
1. Remove hexagon nut (1), spring washer (2) and flat washer (3).
2. Remove set screw M4 (4).
3. Remove shaft holder.
Attention:
1. You should never touch the hexagon nut (9) (painted in red). Re-assemble by reversing the disas-
sembly instructions.
2. Do not over tighten the hexagon nut which should allow the holder arm (10) move up and down
smoothly. The clearance between flat washer (3) and hexagon nut (1) should be about 0.5mm.

Troubleshooting
1. The gripper is locked in the raised position
Remedy:
1. Turn the motor switch OFF, then turn it on again
2. If this does not work, adjust the switch level below the slide for LS1, so that activation and
disactivation of LS1 is correct.
2. The roller is wedged against the guide
Remedy:
Remove shaft holder, loosen and set screw for fixing the guide (11), and then refix the guide with a
clearance of 0.1- 0.2 mm
3. Bad sealing
Remedy:
In most cases of poor heat-sealing, the heater temperature is either too low or too high. Make the ap-
propriate adjustment.
4. Low heater temperature
The strap shows no trace of having been melted and is easily pealed off. Lower the heater tempera-
ture by adjusting the control knob on the heater transformer.
5. High heater temperature
The strap is deformed, curled or poorly aligned and not sealed.

Troubleshooting
6. Strap will not reverse for tensioning
Remedy:
The Strap is in the correct position, but sealing doe
not take place, which occurs when a soft article
(package) is being loosely strapped and the friction
plate in the tightening adjustment section is slipping.
1. Turn off the motor switch, wait until the motor
completely stops and turn the switch on again.
2. You may slightly turn the tightening adjustment
nut A in the clockwise direction to increase the
tension.
The same problem may also occur when there is oil on the tightening roller causing the strap to slip.
Keep the roller clean and free of oil.
