Before reassembling the helmet make sure that all the pieces
are dry.
7. Disassembly
For the outside, proceed as follows:
1)
Unscrew the screws (fig. 1, point 1 and 6) on the sides.
2)
Remove the piece (fig. 1, point 5), being careful to
detach the central portion from its hinge.
3)
Remove the visor (fig. 1, point 4).
4)
Remove the On/Off stopper (fig. 1, point 3).
5)
Remove the part of the helmet (fig. 1, point 2).
For the inside:
1)
Extract the clips of the webbing from the insertion
points on the head-piece.
2)
Extract the clips from the adjustment band.

8. Assembly
For the outside, proceed as follows:
1)
Position the screw in the special housing found in the
headpiece (fig. 1 point 1)
2)
Insert the On/Off stopper (fig. 1 point 3)
3)
Insert the visor (fig. 1 point 4)
4)
Position the piece (fig. 1 point 6)
5)
Lightly tighten the screw (Fig. 1 point 1 and 6)
6)
Repeat the operation on the opposite part.
7)
Firmly tighten both screws.
For the inside:
1)
Insert the clips in the adjustment band, as shown in
figure 4, being careful to place the longest on the front
portion.
2)
Insert the entire webbing and place the clips in the
special housings found on the head-piece, beginning
from the front and gradually moving to the right and to
the left, finishing in the rear

9. Adjustments
Figure 3
Figure 2
There are two types of adjustment.
Width:
by utilising the specially designed system, the helmet size can
be changed from 52 to 66.
Height:
When installing the webbing, the wearer can decide how the
helmet is to sit on the head. The height is adjusted by moving
the clips from insertion point no. 1 in figure 3 to point no. 2 in
figure 3.
For intermediate adjustments, use only a portion of the clips.

IV - VISOR FOR ARCFLASH PROTECTION
0. Introduction
An electric Arc Flash is a fault current, e.g. generated by a
short-circuit traveling through ionized air
– the so called
plasma. Together with tremendous amounts of convective heat
an arc flash comes along with disastrous doses of
electromagnetic radiation (i.e. extremely high levels of
ultraviolet radiation (UV) and high energy visible light). The
explosively expanding heat generates extreme noise (i.e.
explosion bang) and a rapidly progressing pressure wave
–
most probably accompanied by flying debris (e.g. fragments,
molten metal). An arc flash incident usually is caused by a
system fault or a handling mistake in a high current electrical
environment, regardless whether this is a low, medium or high
voltage system. With the CATU Arc Shield your eyes and face
are protected by leading edge Personal Protection Equipment
(PPE) minimizing the effects of an arc flash accident to your
face and eyes, when correctly selected and used. To be
properly protected you must carefully study this manual before
use!
1. General Warnings
➔
Do not over expose to sunlight
➔
Do not use for welding
➔
Do not expose to open fire for long periods of time
➔
Surface may get hot when exposed to electromagnetic
radiation
➔
Replace when exposed to chemicals
➔
Replace if damaged by mechanical impact
➔
Only use original replacement parts
➔
Make sure that your work place is sufficiently illuminated
Insufficient packing may decrease the level of protection.
Thus, follow the instructions as per Chapter 6 'Storage'.
The following warnings are standard warnings as per EN 166:
➔
Material which may come into contact with the wearer's
skin could cause allergic reactions to susceptible
individuals. (REMARK: CATU carefully selects the
materials and is not aware of any allergic reaction so far.)
➔
The CATU Arc Shield protects against high speed
particles. When worn over standard ophthalmic spectacles,
they may transmit impacts, thus creating a hazard to the
wearer.
2. Field of Application
The CATU Arc Shield, permits the user to work at live parts or
remain in the vicinity of live parts. The CATU Arc Shield only
provides safety, if used as intended. Do not use for electric arc
welding or use / store close to arc welding work.
3. Description
The Arc Shield consists of a face shield with permanently
attached chin protector made of arc protective fabric (ASTM
F1959/F1959M-06ae1)
4. Usage
4.1. General
Always check the product before use. The visor must be in the
deployed position when working at live parts or in the vicinity of
live parts (live working). Assure that the gap to your neck is
minimized. For 360° protection add a balaclava.
