Section 1 Introduction 1*1. Wanting- The 3M W-310 Alrhat System should be used only by qualified persons property trained In ite use end main tenance, in accordance with these operating end maintenenee instructions; Each pcrconwho wHI be using the* Alrtiet should read end underatenothle entire operating end melntenence inatnictlon manual first Use of the Alrhat by untrained or unqualified persona, or use not In accordance with these instructions, can be dangerous. 1-2. Oenerel Osscitpttou The 3M W-318 Alrhat System provides head, eye, and respiratory protection In one comfortable, light weight, easyto-use package, The Alrhat allows total mobility. There are no cumbersome sir hoses or backpacks to get In the way. The Alrhat eliminates the need to wear individual hardhats, safety goggles, and respirators. The 3M W-316 Alrhat System consists of an inner helmet shell and an outer helmet shell. Between the (wo helmet shells Is mounted an axial fan and filter aesemoly. A hinged face shield Is attached to the outer helmet shell end can be latched In the up or down position, a soft, flexible face seel on the face shield frame provides a qood fit to the wearer's face when the face shield is latched in the down position. The fan motor Is powered by a small, lightweight nickel' cadmium battery pack worn on e bait around the waiete Whan fully charged, the battery peck provides enough power for at least ten hours usei The battery peck is rechargedwith the chargerprovided. A full charge requires at least touRsem hours. The battery peck cannot be overcharged. No harm is done to the battery peck It (t la connected to the charger continuously. 1*3. Principle of Operation flee figure M) Air is drawn through the pre-filter at the back of the helmet. The pre-filter stops the larger particles, helping to protect the fan end motor and prolonging the Ufa of the main filter. Air from the fan then passes througn the main filter, is channeled between the inner and outer helmet shells, and flows down over the face, creating s comfortable, cooling effect. The air exits around the temple ares between the inner shell and the wearer's head. Again, it Is extremely important that each and every Alrhat user reed end understand this entire manual first. Use of this product other then SDeciffed within this manual could be dangerous to the life ana health of the user. 3 ABDOO140426 34l aanecstoTheheadsuepenafon system has not beer*' inaiadadln yourhalmsealncd --eft suspension system requeee different edjusbnent to suit the wearer.
