USER MANUAL
All the hearing protectors which are included in this instruction sheet are
equipped with or spring-arms, and foam plastic-filled cushions. This hearing
protector is intended to protect the wearer from hazardous noise levels when
fitted in accordance with these user instructions. Any other uses are not
intended and therefore not allowed.
Hereby, KASK S.p.a. declares that the hearing protector SC is in compliance
with the PPE regulation EU 2016/425 and other appropriate directives to
fulfill the requirements of CE marking. The full text of the EU Declaration of
Conformity is available at the following internet address: www.kask.com For
the manufacturing date, see the date clock on the inside of the ear cup. The
expected lifetime of a product is 5 years.
Warning!
It is important that the instructions for use are followed. Failure to do so
could result in a drastic reduction in the noise attenuation and may lead to
serious injury.
Carefully read these user instructions!
- The hearing protector must be used at all times in noisy environments to provide the full protection effect! Only 100% wear time provides full protection.
- The audibility of warning signals at a specific workplace may be impaired if over protected, when using a hearing protector with a too high noise attenuation performance in relation to the noise environment.
- Certain chemical substances can have a destructive effect on this product. More information is available from the manufacturer.
- Ensure that the hearing protectors are regularly inspected for serviceability.
- The hearing protector’s noise attenuating properties can dramatically decrease with usage of for example thick spectacle frames, ski masks/balaclavas, etc.
- Use of perspiration/hygienic protection over the sealing rings can reduce the hearing protector’s noise attenuation properties.
- Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and leakage.
- Immediately discard the product if showing signs of cracks or damage.
- Hygiene kit should be changed at least twice per year. Make sure you choose the correct hygiene kit for your hearing protector.
- Clean the product with mild soap. You must be sure that the detergent you usedoes not irritate the skin. Do not dip the product in water.
- The hearing protector must be stored in a dry and clean environment out of direct sun light, e.g. in its original packaging.
Fitting & adjustment
Brush away all hair from the ears and place the hearing protectors over the ears so that they fit comfortably and snugly. Ensure that the ears are completely enclosed by the hearing protectors and that you have even pressure around the ears.
Helmet/Cap mount (A)
Push the hearing protector’s helmet attachment into the helmet slot until it
locks into position. Place the hearing protectors over the ears and press
inwards until you hear a click. Adjust the hearing protectors and helmet so
that they fit comfortably on your head.
Change of hygiene kit (B)
- Remove the old sound-absorbing foam and insert the new.
- Pull off the old ear cushion.
- Centre the new ear cushion over the hole.
- Press with a finger along the outside of the ear cushion until it attaches all around the edges.
Approval and technical data (C)
- C4) Tested and certified to (standards)
- C5) Weight
- C6) Mean attenuation
- C7) Standard deviation
- C8) Assumed Protection Value
- C9) Tested and certified by (notified body)|
Approved helmet combinations (D)
These earmuffs should be fitted to, and used only with the industrial safety
helmets listed in table D.
- D1) Manufacturer
- D2) Model
- D3) Adapter
Earmuffs complying with EN 352-3 are of the medium size range or small size
range or large size range.
Medium-size range earmuffs will fit the majority of wearers. Small-size range
or large-size range earmuffs are designed to fit wearers for whom medium-size
range earmuffs are not suitable.
Accessories and spare parts
Hygiene kit SC1 & SC2: WAC00006
Hygiene kit SC3: WAC00007
Information required by E.P.A. (US)
The level of noise entering a person’s ear, when a hearing protector is worn
as directed, is closely approximated by the difference between the A weighted
environmental noise level and the NRR. Example: The environmental noise level
as measured at the ear is 92 dBA. The NRR is 25 decibels (dB).The level of
noise entering the ear is approximately equal to 67 dB. Caution. For noise
environments dominated by frequencies below 500 Hz the C-weighted
environmental noise level shall be used.
Warning. Improper fit of this device will reduce its effectiveness in
attenuating noise. Although hearing protectors can be recommended for
protection against the harmful effects of impulse noise, the noise reduction
rating (NRR) is based on the attenuation of continuous noise and may not be
accurate indicator of the protection attainable against impulse noise such as
gunfire.
