Grex G4.2 PRO Sécurité Et Instructions D'utilisation page 14

INSTRUCTIONS FOR USE
The G4.2 PRO helmet is equipped with a removable protective chin guard and
can be used with different configurations (Fig. 1): with visor and chin guard,
with visor only, with chin guard only, without visor and chin guard. Using the
helmet in its full configuration - with chin guard fastened and visor pulled down
- definitely guarantees a higher level of protection if compared with the other
possible configurations.
The chin guard locking slot covers - which have to be assembled if the helmet is
used without chin guard - are included in the box. The side plates - which should
be assembled if the helmet is used without visor - are available on the product
itself, in the box or as accessory / spare parts - depending on the version of the
product.
VISOR
1. Visor Disassembly
1.1. Lift and release the left safety cover from its lateral latch (Fig. 2).
1.2. Turn the latch 90° towards the front of the helmet (Fig. 3).
1.3. Remove the latch from the helmet by pulling it outwards so that the latch inner
bayonet "A" comes out of its housing in the visor mechanism (Fig. 4).
1.4. Remove the visor by holding its side end and bending it outwards so that the
hole "B" of the visor comes unhooked from the mechanism and the inner pin "C"
comes out of its housing in the mechanism (Fig. 5).

When using the helmet without visor, follow the instructions below starting from

bayonet "A" in its housing in the side mechanism (Fig. 4).
NOTE: The left and right safety covers and lateral latches are different from each
other and are marked on their back as R (Right) and L (Left).
2.3. Turn the latch 90° towards the back of the helmet. Carry out this operation by
pushing the latch towards the inside of the helmet (Fig 3).

making sure that the mechanisms hold it in the different positions. If necessary,
repeat the above-mentioned steps.
