FITTING INSTRUCTIONS:
1. 先将头带每隔2-4厘米处拉松，手穿过口罩头带，金属鼻位向前。

2. 戴上口罩并紧贴面部，口罩上端头带位放于头后，然后下端头带拉过头部，置于颈后，调校至舒适位置。

3. 双手指尖沿着鼻梁金属条，由中间至两边，慢慢向内按压，直至紧贴鼻梁。

4. 双手尽量遮盖口罩并进行正压及负压测试。（正压测试：双手遮着口罩，大力呼气。如空气从口罩边缘溢出，即佩戴不当，须再次调校头带及鼻梁金属条；负压测试：双手遮着口罩，大力呼气。口罩中央会陷下，如有空气从口罩边缘进入，即佩戴不当，须再次调校头带及鼻梁金属条。）

Fitting Instructions:
to be followed each time respirator is worn.

1. Prestretch top and bottom straps before placing respirator on the face (8210/07048). Not necessary for
8110S.
2. Cup the respirator in your hand, with the nosepiece at your fingertips, allowing the headbands to hang
freely below your hand.
3. Position the respirator under your chin with the nosepiece up. Pull the top strap over your head
resting it high at the top back of your head. Pull the bottom strap over your head and position it
around the neck below the ears.
4. Place your fingertips from both hands at the top of the metal nosepiece. Using two hands, mold the
nose area to the shape of your nose by pushing inward while moving your fingertips down both sides
of the nosepiece.
! Pinching the nosepiece using one hand may result in improper fit and less effective respirator
performance. Use two hands.
5. Perform a User Seal Check prior to each wearing. To check fit, place both hands completely over the
respirator and exhale. Be careful not to disturb the position of the respirator. If air leaks around
nose, readjust the nosepiece as described in step. If air leaks at the respirator edges, work the straps
back along the sides of your head.
