EN352-3:2002 (helmet mounted version).
FITTING INSTRUCTIONS
Before following the fitting instructions below, brush excess hair aside and remove any ear jewellery that could affect
acoustic seal. The cushions should form a snug fit against the head with no interference of the seal by any objects e.g.
respirator headbands or spectacles arms, and that the cups completely enclose the ears.
Headband version:
A 1: Make sure to put the headband the right way round. The inside of the headband is marked with a letter L on the left
hand side and a letter R on the right hand side. Ensure that the headband is positioned correctly.
A 2: With the headband over the head, adjust the height of the cups by sliding them up or down so they completely
enclose the ears.
Helmet attachment:
B 1: Left and Right cups. The cups are designed to be used either on the left hand side or on the right hand side of the
helmet. The cup marked with a letter L must be put on the left hand side of the helmet and the cup marked with a letter
R must be put on the right hand side of the helmet. Make sure to put them the right way round.
B 2-3: Fitting the cups. Pull the ear cup down to the bottom of the yolk and lift the blade until the spring clicks up (2).
Push the attachment blade firmly into the slot on the side of the helmet until it clicks into place (3).
B 4: Working Position. Adjust the cups until they are comfortable. Make sure that the cushions seal tightly around the
ears. NOTE! In noisy environments, the ear-muffs must be worn in the working position at all times.
B 5: Stand-by position. Pull the ear-muff away from the ear until it locks into the stand-by position.
B 6: Parking Position. First lift the cups to the stand-by position, and then rotate them up to the next fixed position. In
this position, the cushion does not get damaged or dirty and the cups can dry out on the inside. NOTE: Do not press the
cups onto the helmet shell as this will lock the spring in the ear-muff arm, and damage the attachment slots on
the side of the helmet.
B 7: Storage Position. When the helmet is not in use, lower the ear-muffs and press them inward.
STORAGE
When the hearing protector is not in use, store it in such a way that the headband is not stretched and the cushions are
not compressed. Keep the ear-muffs dry and clean, store them at normal room temperature and do not place them in
direct sunlight.
MAINTENANCE
Clean and disinfect the cups, cushions and inserts with mild soap and water only. Ear-muffs and cushions in particular
may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for example at the start
of every working shift.
HyGIENE KITS
The cushions and inserts are replaceable. Always replace worn or damaged parts. Remove the cushion by pulling it
straight out (C1). Replace the old cushion and insert with new ones from the hygiene kit (C2). Use only hygiene kits
from the manufacturer, consisting of one pair of cushions and one pair of inserts. It is recommended that the hygiene
kit should be replaced at least twice a year for standard use to ensure that the noise attenuation performances are
maintained. For order reference, please refer to Table 3.
