7. Inspection and Adjustment
7.1 After opening the
container
, check whether accessory is completely, and the screws in all parts of the
machine are tighten and the organic glass cover move up and down freely.
7.2 Lubricate the moving parts, oil hole and oil nozzle regularly. Add rational gasoline,
vacuum oil
into vacuum
pump, oil level is between 1/4-3/4 of oil window.
7.3 Adjustment
7.3.1 Vacuum degree adjustment
According to the requirement of packing goods, choose the best exhausting time to obtain the appropriate
vacuum degree. The longer exhausting time, the higher vacuum degree.
7.3.2 Adjustment of heat-seal time and temperature
According to the bag material and different product, choose the best heat-seal temperature (1-3 shifts adjustable)
and heat-seal time (0.1-9.9second) one panel. Adjusting is from low to high until the best seal intensity and
appearance.
8. Operation Process
8.1 Connect to power supply, turn on the power switch, namely, the pilot lamp is on, Set exhausting time, heat-seal
time and heat-seal temperature.
8.2 Put the product into packing bag (plastic compound or aluminum foil bag) into the vacuum chamber and put
the bag top under heating seal strip orderly.
8.3 Press cover down, and the pilot lamp for vacuum in panel is on. The vacuum pump is exhausting, and the
cover is sucked automatically. Adjust vacuum time according to the packing requirement.
8.4 When the exhausting time reaches the set one (required vacuum degree), the process are finished, and the
pilot lamp is off. Now the pilot lamp for heat-seal time is on and begin to seal. There are heat-seal time and
temperature adjustment buttons on panel to adapt the different thickness material, and according to the specification
of bag.
8.5 When time reached the preset, the pilot lamp is off. It means the heating seal is finished and exhausting
electromagnetic valve works. The air enters into vacuum chamber, and the cover is lifted up. Now the packing
process is completed and turns to next process.
9. Troubleshooting
9.1 Can not vacuum and vacuum degree is low
9.1.1 Check if the vacuum pump rotates anticlockwise, and the rotating direction of vacuum pump is the same as
the arrows marked in motor.
9.1.2 When using new machine, the gasket in cover doesn’t touch the vacuum chamber well.
9.1.3 Check if the micro-switch is connected well.
9.1.4 The release electromagnetic valve isn’t closed well, check if the release electromagnetic valve and its axis
(rubber) is damaged or polluted and its axis is moving away. Please repair if replace if appears above states.
9.1.5 Check if the parts are leakage or loosed.
9.2 The heat-seal quality isn’t good.
9.2.1 Check if the bag mouth is clean.
9.2.2 Check if the heating element works regularly.
9.2.3 Check if the transformer output the voltage, if it isn’t output, please check the input circuit. If transformer has
input but without output, replace the transformer.
9.3 Main board trouble
9.3.1 Keep electric circuit of main board clean and dry. Not allow the metal on surface in order not to cause
short-circuit of main board interior, or the procedure chaotic.
9.3.2 Machine doesn’t vacuum and heat-seal, check the relative plug is connected well or button is damaged.
9.3.3 The digital board shows the trouble or without action indicates, check the plug of digital board is loose or
digital board is damaged.
9.3.4 One of heat-seal shifts is out of work, check the plug of relative relay isn’t connected well or the relay is
damaged.
