3. CLEANING AND MAINTENANCE
Use a cloth wetted with soap and warm water to clean the
outer shells, headband and ear cushions.
NOTE: Do NOT immerse the hearing protector in water.
If the hearing protector gets wet from rain or sweat, turn the
earmuffs outwards, remove the ear cushions and foam liners,
and allow to dry before reassembly. The ear cushions and
foam liners may deteriorate with use and should be
examined at regular intervals for cracking or other damage.
When used regularly, 3M recommends replacing the foam
liners and ear cushions at least twice a year to maintain
consistent attenuation, hygiene, and comfort. If an ear
cushion is damaged, it should be replaced. See spare parts
and accessories section below.
3:1 Removing and replacing the ear cushions
D:1 To remove the ear cushion, slide your ngers under the
inside edge of the ear cushion and rmly pull straight out.
D:2 Remove existing liner(s) and insert new foam liner(s).
D:3 Fit one side of the ear cushion into the groove of the
earcup and then press on the opposite side until the ear
cushion snaps in place.
3:2 Use and storage conditions
Remove the batteries before storing the product. Do not
store the hearing protector at temperatures above 55 °C or
131 °F, (for example on a dashboard, parcel shelf or window
sill), or at temperatures below –20 °C or –4 °F. Do not use
the hearing protector at temperatures above 55 °C or 131 °F,
or below –20 °C or –4 °F.
