We have become aware that insufficient lubrication may have been applied to the bypass valve assemblies on FireHawk M7XT Air Masks when manufactured. A lack of sufficient lubricant could cause the bypass assembly to become difficult to operate or possibly inoperable. No injuries have been reported. Until your affected units have been serviced as described in this notice, please be aware of any degradation in how easily the bypass valve operates when performing your pre-use functional tests as described in the users’ instructions. If degradation is apparent, that Air Mask should be removed from service until it is corrected. CLICK HERE for the Safety Notice
