There is a danger of electrocution or malfunction of the machine. Warning Do not insert any metal objects into the sealing area Please do not place any metal objects into the sealing area during operation. This could cause electrocution. Warning When replacing parts, unplug the power plug Maintenance of the machine is important. Parts should be replaced in accordance with the operating instructions. There is a risk of danger if the parts are not replaced properly. Before replacing parts, unplug the machine from the power source and replace parts referring to Replacing the routine maintenance parts thoroughly. Warning Do not modify the machine Modification of the MS-350 NP series or the use of unspecified parts may not only lead to damage of the machine, but there is also a risk of danger to the operator. Please do not tamper with the machine. Accidents or damage caused by modification by the customer is the sole responsibility of the customer. 8
Warning Do not use parts other than those specified When replacing parts, always use only specified parts sold through Fuji Impulse. Not responsible for malfunctions caused by the use of unspecified parts. Warning If the power switch automatically turns to the OFF position If after 3 seconds heating is not complete after it has been initiated, the power switch will automatically turn OFF. There is a possibility of malfunction of the machine. Do not operate the machine until the cause of the shut down is ascertained and the problem has been addressed. Caution Do not use in the following places Do not operate machine in the following places since there is a danger of malfunction: 1 Dusty locations. 2 Locations not within normal temperatures. 3 Locations with high humidity. Caution Do not place hands in the sealing area With prolonged use, the sealing area will retain heat and become hot. If you place your fingers in this area, there is a possibility of burns. Do not place hands between the seal jaws (pressure lever and seal frame). Should the foreign objects such as fingers are clamped between the sealing area and the sealer cannot move to the heating process within 0.5 seconds, the lever automatically returns to the initial position. However, the strong pressure is applied especially to the both ends to the sealing area, and there a danger that the sealing process may start without notice. Caution Use the machine properly Read Proper use of the sealer in this manual carefully and operate sealer correctly. Accidents or damage caused by misuse of the machine not in accordance with the operating instructions are the sole responsibility of the customer. Caution Run test trials first before beginning operation Achieving a superior seal with an impulse sealer is determined by heating / cooling / pressure strength. Depending on the type of film being used and the contents of the bag, heating / cooling / pressure strength conditions may drastically differ. Find the optimum sealing conditions by conducting seal tests before proceeding. 9
For smooth operation Heating temperature should be set at a minimum Set sealer so that an acceptable seal is completed at the lowest heating temperature. Excessively high heating temperatures will damage the Teflon, glass tape and other consumables, as well as result in heating element breakage. This will lead to decreased work productivity and unnecessary power consumption. Set the cooling temperature depending on the film Cooling process is important when using an impulse sealer. After the film is heated, the film must cool with the frame and pressure lever in the closed position. Setting the cooling temperature excessively low will decrease the work productivity. Set the cooling temperature that is suitable for each film. When the Teflon, silicone rubber becomes damaged The Teflon, silicone rubber will start to wear with use. Once they are damaged, it will be difficult to achieve smooth and strong seals. Thoroughly read how to replace the parts and be careful when doing so. To achieve a strong seal Proper sealing pressure is important in achieving a strong seal. Follow directions on proper sealing pressure adjustments and set accordingly. (Refer to 10-1 Adjusting the seal pressure.) Dust in the sealing area Dust will prevent attainment of a smooth seal. It could also cause damage to heating element and/or other routine maintenance parts. Before using the machine, clean the sealing area. 10
Other safeguards Run test trials before beginning operation Depending on the type of film being used, heating / cooling / pressure strength conditions will differ. Run test trials to find the optimum sealing condition, especially when trying to find the tightest seal possible. The Fuji Impulse MS-350 NP series is an impulse sealer Do not become alarmed if the sealing area does not become hot after the power switch is turned ON. The machine has not malfunctioned. The Fuji impulse sealer uses an impulse method so the heating element will not become hot just by plugging the unit in or turning the power switch to the ON position. The heater will only become hot for an instant when the heating process is in operation. However, after extended periods of use, the sealing area may become hot. If there is a malfunction in the temperature sensor The temperature sensor is designed to monitor and control heating temperature by directly measuring the heater temperature. Therefore, the machine will not operate when the sensor tip is not positioned correctly or the sensor is disconnected. When replacing the consumable parts such as heating element or the temperature sensor, please be sure to position the temperature sensor correctly. Please refer to 10-2 Replacing the temperature sensor for the detail. 11

11 Adjusting each part 11-1 Adjusting the seal pressure Seal pressure is adjusted at the time of factory shipment so the optimum seal pressure can be achieved at the position of S (standard). H on the lable indicates high, and L is for low. 1 Remove a frame cover. Completely close seal levers by pushing the upper lever with your hand. 2 Install a pressure adjusting nut with shaft to the hole and turn it clockwise until it stops. You will have to turn it about 4 to 5 full turns. Pressure adjusting nut Caution If the pressure adjusting nut is not fully screwed in, it may cause sealing failure or cause the pressure lever to remain at the lowered position due to the solenoid suction strength dropping and the microswitch not being activated. 3 The pressure adjusting nut will stop roughly at the position of H as in the right illustration. 4 Then return the nut about a half turn counterclockwise. 5 Again turn the nut clockwise and set it to the position S (standard). Once the adjustment is made, always use the securing screw to secure the pressure adjusting nut. Caution If the pressure is set excessively high (to the direction of H), it will increase the sound of the pressure lever movement. Attention If the pressure is set excessively high (to the direction of H), a solenoid may make a chattering noise. In that case, turn the pressure adjusting nut to the direction of S. 28
11-2 Adjust the depth of seal position 1 Loosen the white plastic screws (5x10) on both sides of the seal receiving plate. 2 The seal (position) guide can be slid back and forth to adjust the depth of the pouch insertion. Adjust the seal gauge position so the heating element comes to the place you would like to seal. 3 Once the seal position is determined, fix the seal gauge with the white plastic screws.
