Got yourself one of Euromarc's awesome new CRAFTSMAN 710 Respirators, or thinking about getting one? You're making a great choice! They're really simple to use, while still providing the best protection. Check out the fitting and fit test instructions below...

Fitting the filters

1. Check identification on the filters to ensure you have the correct filters for the application.

2.  a) Align the filter bayonet fitting with the face-piece bayonet fitting.
b) Rotate 1/4 turn clockwise to attach.

CAUTION: Over rotation will result in damage to the filter and face-piece.

Note: These filters are supplied in pairs of identical classes and type and must be fitted, used and replaced at the same time. 3. Leave work area immediately, check integrity of respirator, and replace any parts if:
  • Damage has occurred or is apparent
  • Dizziness, illness or irritation occurs
  • Breathing resistance increase
Dispose of all used filters.

Fitting the respirator

1. The filters have a 3-point locking system - align openings on the back of the filter with the fitting on the mask, press and turn filter clockwise until it is firmly attached (see instructions above).

2. With one hand hold the respirator over the mouth sitting it on the bridge of the nose, then fit head harness over the crown of the head with the other hand, taking care that the elastic straps are not twisted.

3. Hook the two bottom straps together behind the neck.

4. Firstly, tighten the head harness by pulling on the ends of the straps – ensure a comfortable but firm and secure fit. Tighten the bottom straps in a similar manner (Strap tension may be decreased by pushing out on the back side of the buckles).

Drop-down suspension

5. To change to a drop-down suspended mask, un-hook the straps at the front of the mask where the arrows are, and have the strap out on top of the arrow, to be able the respirator to slide on the straps.

6. To bring the mask back into position, hold the straps together and slide the respirator back into position over your mouth and nose. Now repeat steps 2, 3 and 4 to fit mask.

Conducting a fit check

 1. Positive-Pressure test: place the palm of your hand over vent in the exhalation valve cover and breathe out. If no air leaks are present the mask will bulge out – you have a good seal.

2. Negative-Pressure test: press your palms firmly over the filters, try and cover as much area as possible, inhale gently and hold your breath briefly. If no air leaks are present the face piece will collapse slightly - you have a good seal.
 
 3. If you detect any air leaks in either test try re-positioning the respirator on the face and/or adjust the tension on the elastic straps. You may need to use a different size.
 
 4. Repeat steps 1-3 until you have a good seal.   

If you CANNOT achieve a proper fit DO NOT enter the hazardous area. It is recommended that wearers should be fit tested in accordance with AS/NZS 1715.

Maintenance and Cleaning

Euromarc recommends cleaning the mask after each use.

Use the designated respirator cleaning wipes, and wipe the face seal and internal surfaces, or remove the filters and wash in warm clean water (below 50° C).

Leave to air-dry at room temperature in a clean environment.

CAUTION: using cleaners containing oils, detergent or abrasive chemicals can destroy the integrity of the mask. Masks and filters should be inspected before each use as described above. Damaged masks should be discarded.

Storage

Masks should be stored in their original packaging in dry, clean conditions, between -10 to +40°C, and away from direct sunlight, high temperature, chemicals and vapours.

Masks have a life-span of 5 years from date of manufacture, including shelf-life and time in-use. The date of manufacture can be established by examining the date clock on the inside of the face piece. After each use and cleaning, masks should be stored in their original packaging or a sealed container, do not store in contaminated areas.
