SECTION 1 − PAPR SAFETY PRECAUTIONS − READ BEFORE USING PAPR 2010−03 Protect yourself and others from injury — read and follow these precautions. 1-1. Symbol Usage DANGER! − Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text. Indicates special instructions. Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
NOISE can damage hearing. Noise from some processes or equipment can damage hearing. Wear approved ear protection if noise level is high. READ INSTRUCTIONS. Read and follow all labels and the Owner’s Manual carefully before installing, operating, or servicing unit. Read the safety information at the beginning of the manual and in each section. Use only genuine replacement parts from the manufacturer.
RESPIRATOR (PAPR) MISUSE can be hazardous. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Read and follow these instructions and the safety labels carefully. The powered air purifying respirator (PAPR) helps protect the user from specific airborne contaminants but must be used correctly to be fully effective. Have an industrial hygienist test the air in your facility to ensure the PAPR provides adequate protection from contaminants in your environment.

POWERED AIR PURIFYING RESPIRATOR 2-11. Putting On The Respirator . Do not enter a hazardous area until you are sure the respirator equipment is correctly assembled, working properly, and properly worn. . Leave the contaminated area immediately if the Danger light goes On, the alarm sounds, or the blower vibrates. Do not remove the equipment until you are in a safe area. See Parts List in Section 4 for optional belt extension. Place blower assembly against lower back with hose extending upwards.
POWERED AIR PURIFYING RESPIRATOR 2-12. Maintenance And Storage Replace damaged or dirty air filters. Do not wash filters, clean with compressed air, or reuse dirty air filters. Never use solvents or abrasive cleaning solutions to clean the respirator. Keep water and other fluids out of blower assembly. Maintain accurate records of filter replacement and respirator maintenance. For best performance clean the equipment after each use.
POWERED AIR PURIFYING RESPIRATOR Battery run time is too short. Replace battery. Check air filter and replace if necessary (see Sections 2-4 and 2-7). A clogged air filter element reduces battery life. Danger light is On, alarm sounds or blower vibrates. Continue wearing the respirator and leave the contaminated area immediately. Check blower air flow (see Sections 2-4 and 2-7). Remove blockage from blower outlet and/or hose.

AUTO-DARKENING HELMET 3-2.
AUTO-DARKENING HELMET 3-3. Reset Button And Low Battery Indicator The auto-darkening lens turns on (darkens) automatically when welding begins and turns off 15 − 20 minutes after welding stops. 1 Reset Button Press Reset button to check if the lens is working properly. When the Reset button is pressed, the lens should darken twice and return to the clear state. Do not use the helmet if the lens does not function as described. (See Section 3-13, Troubleshooting.
AUTO-DARKENING HELMET 3-5. Variable Shade Control (No. 8 − 13) 1 Variable Shade Control (No. 8 − 13) Use the control to adjust the lens shade in the darkened state. Use the table below to select proper shade control setting based on your welding process. Start at shade 12 and adjust lighter to suit the welding application and your personal preference. 1 Application Welding Arc Current in Amperes Protective Shade No.
AUTO-DARKENING HELMET 3-6. Sensitivity Control 1 Sensitivity Control Weld Mode Use control to make the lens more responsive to different light levels in various welding processes. Use a Mid-Range or 30−50% sensitivity setting for most applications. It may be necessary to adjust helmet sensitivity to accommodate different lighting conditions or if lens is flashing On and Off. Adjust helmet sensitivity as follows: Adjust helmet sensitivity in lighting conditions helmet will be used in.
AUTO-DARKENING HELMET 3-7. Adjusting Headgear On Standard Models There are four headgear adjust- ments: headgear top, tightness, angle adjustment, and distance adjustment. 1 3 1 Headgear Top Adjusts headgear for proper depth on the head to ensure correct balance and stability. 2 Headgear Tightness To adjust, push in the adjusting knob located on the back of the headgear and turn left or right to desired tightness. 3 Distance Adjustment Adjusts the distance between the face and the lens.
AUTO-DARKENING HELMET 3-8. Replacing The Lens Covers On Standard Elite Helmets .

Remove retaining clips from shield. Install clips in same location on new shield.
AUTO-DARKENING HELMET 3-10. Replacing The Battery To replace the batteries, remove the auto-darkening lens assembly (see Section 3-8). 1 1 Battery Tray After removing the lens assembly, slide the battery holding trays out and remove the old batteries. + + Be sure Positive (+) side of battery faces up. Replace with CR2450 lithium type batteries (2 required) or equivalent (Miller Part No. 217043). Be sure Positive (+) side of the battery faces up (toward inside of helmet).
AUTO-DARKENING HELMET 3-11. Installing Optional Magnifying Lens 1 1 Optional Magnifying Lens Starting at the bottom, slide magnifying lens into the helmet retaining brackets. Align the magnifying lens with the auto-darkening lens assembly. Remove lens holding frame (with auto-darkening lens) from helmet shell. Remove auto-darkening lens from lens holder. Position lens holder with magnifying lens holding tabs facing toward you. From the bottom up, slide magnifying lens into position.
AUTO-DARKENING HELMET 3-13. Troubleshooting Trouble Remedy Auto lens not ON – autolens will not darken momentarily when the Reset button is pressed. Check batteries and verify they are in good condition and installed properly. Also, check battery surfaces and contacts and clean if necessary. Check battery for proper contact and gently adjust contact points if necessary. This is particularly important if the helmet has been dropped. Verify left and right battery trays are installed on the correct sides.
