4. Installation
Just need to tight connect the breathing tube with the main body and hood.
5. Using methods
5.1 Tight connect the battery and main body firstly. Then please check the respirator airflow before using. Press the power switch and plug the end of the airflow indicator in the end of the breathing tube. While the air flow enters the indicator, the bobber in the indicator will float up higher than one scale on the indicator, which indicates that it’s positive pressure now and the respirator can be used normally. Otherwise, the respirator is forbidden to be used. The reasons might be lacking power or filter’s resistance. Please adjust the straps in back and shoulders, the clamp inside the hood based on the personal differences. Then adorn the respirator; press the power switch to turn on it. Rotate the airflow knob to the suitable value. Now the respirator can start to work. An electronic warning system is installed inside the respirator which can buzz automatically when the battery is going to be out of power and then powered off automatically.
5.2 Cautions
5.2.1 Before using, the battery must be charged up. In duration of operation, this respirator must be switched on; otherwise no dust or poison control may be gained. It is prohibited to short circuit connect the product or put it into fire. The battery must be recharged up if not using it in at least three months. Main body（battery is charged up）can work for 6--8 hours continuously. When air flow regulates maximum, the battery can work for 6 hours continuously, when air flow regulate minimum, the battery can work 8 hours continuously. If it works for more than 6--8 hours, stand by battery must be prepared. A adaptor can be used to change the AC 100-240V into DC12V without limited working hours.
5.2.2 Before welding work, check the helmet not damaged and the cover lens is fitted. Never use the helmet without cover lens, or the filter glass will be damaged by the welding splashes.
5.2.3 Select shade (9-13) by the shade select knob to suit the welding current. If not knowing which to use, operator can try from the deepest color, turn this knob anti-clockwise until the window is clear. Mostly the “Sensitivity" knob is adjusted to the middle. However if the welding current is low, please turn the knob clockwise, toward H, to increase the sensitivity. If work at night, please avoid strong light. If it can not work normally, turn the knob to decrease the sensitivity.
5.2.4 Prior to entering welding conditions, please wear this product and switch on the power supply.
5.2.5 There may be a tiny gap in the sections between head cover and face or neck. Please do not worry about it. Because it remains positive pressure within the facial mask, outside dust particles and gases could not get in. If the gap is a little big, please adjust the clamp in the neck of the hood to the comfortable size, as to make sure positive pressure.
5.2.6 If the shade is obviously dark enough, you should change the battery. Take off the spectacles frame，draw out the drawer where hold the standby battery near by the solar battery. Change into a changeable Lithium battery（CR2032）. This battery’s life is 1 year.
5.2.7 After welding you should check the cover lens, if it stained some dust, please wipe it off by soft cloth, or washed by mild solution of soap. Do not use hard cloth or rough paper to wipe it.。After each work the product must be taken away from the work area and conserved airproof. Otherwise the filter will continue to work so that the life will be shorted. Please keep the hood in a cool dry place.
5.2.8 This product does not provide protection against: Oxygen - acetylene welding or Laser welding! And it's also not unsuitable to anoxic (i.e. oxygen content less than 18%) or explosive operating conditions, or IDLH concentration (Immediately Dangerous to Life and Health).
5.2.9 If the environment is anoxic and possibly explosive breath hose could be used so that main body will be safe. The length should not be longer then 20m because of the finity of power of the main body for too long hose would weaken the wind power.
5.2.10 If there is AC power nearby battery needn’t be used under the situation of breath hose. Use adaptor to give the power supply. Thus the time of power supply will not be limited.
5.2.11 If use breath hose, only low-resistance filter (type: 102HD) is suitable for large-air resistance as a long hose will badly influence the air flow of filter. Our company provide filters in various use.
5.2.12 If powered respirator is far from working space, operator works in anoxic like condition with breath hose, there should be person specially assigned for a task of ward. Person outside must communicate with the operators to confirm whether powered respirator is in order. If suddenness happens (powered respirator does not work), operator should be rescued immediately to insure safety.
5.3 Replace for filter、gasket and cover lens
5.3.1 For102D, 102HD high efficiency particulate filter：Filter changing is necessary when you feel much less or no fresh air get in even with enough power supply from the battery, resulting from the fact that the filter may have been filled with fine particles in such case. Take out the filter and knock the windward side so that much dust could be knocked out. Use the soft dry cloth or paper wipes the filter. Put the filter into main body thus it can continue to work. After used time after time the filter may be full of dust that can not knocked out, thus may change the filter.
5.3.2 For 102G、102W high efficiency particulate and gas filter：for dustproof, the way of changing filter is the same as above (refer to 5.3.1)；For gas proof, it depends on whether feel the ill odors. If feel the ill odors or swirl, naupathia that is to say filter box 102G is saturated. It lost the ability to filtrate the poison. It should be changed.
5.3.3 In duration of filter changing, if the purified cavity in the main body kit was contaminated by fine dust from the edge of the filter, the cavity shall be cleaned, otherwise, the dust control effects may be diminished. Subsequent to filter changing, due attention shall be paid to tighten the back cover of the main body kit and secure the filter.
5.3.4 The main body case and filter were cleaned up prior to use the respirator, or a new filter, reeking out an ill odor and dust from the breathing tube while using, that would be likely that the service life of gasket in main body is so long to lose its elasticity resulting of poor airtightness, here it is necessary replacing a new gasket to ensure well airtightness of respirator.
5.3.5 The filter102D, 102G, 102W, 102HD shall not be exposed to water or moisture. If any such exposure, please change in time.
5.3.6 Cover lens should be changed as followed if was damaged by the welding splashes that affect the normal work: Take off the screws in spectacle frame group, change a new cover lens (take off the film) into spectacle frame group, then screw down it.
5.4 Charging
5.4.1 When you feel much less or even no air gets in with a new filter or a filter before the expiration date, the battery power might not be enough. Then the electronic warning system will buzz, then the batteries need to be changed accordingly.
5.4.2 The aperture in the battery compartment is for power supply or charging use.
5.4.3 With the power switches on, insert the charger plug into the aperture in the battery compartment (socket), and connect the charger to 100 ~ 240V alternative current power supply and the charging is in progress.
5.4.4 When the charger begins operation, the indicator will turn red indicating the initiation of charging and then turn green indicating the completion of it.
5.4.5 6hrs charge is enough. The intelligent charger may avoid batter damage resulting from overcharging.
