How to Open your G4 Visor
Place your index finger in position A on the top of visor locking plate and your thumb on the bottom
position B. Next you will need to push the visor locking plate in the forward direction unlocking the
mechansim. Once you have moved the visor locking plate forward 9mm or 3/8 .inch [•) you can now
begin to rotate the visor locking plate in an upward direction. It is best to do this with the G4 on your
head. It may take a couple of tries to perfect the movement and holding your elbows upwards in line
with your shoulders can assist with this movement. To close the visor, simply hold the top of the visor
and rotate downward. The visor will make a loud sound as it locks into place and the springs return
the visor to the locked position.

The G4 Helmet is certied according to Standard XP S 72-600 and is designed exclusively for Skydiving
and Wind tunnel use and should not be worn for any other activities. It should not be used on Motorised
and Non-Motorised means of transport. This helmet is intended to reduce the user’s risk of head injury
within the area covered by the helmet This helmet is not a toy. Do not let children wear it while climbing
or doing other activities as there is a risk of hanging/strangulation. For best protection, the helmet must
be properly tted and attached to the user’s head. Read the user’s manual and follow all warnings and
instructions before using the helmet. This helmet is designed to absorb energy of one signicant impact
and should be replaced after such an event. In the event of any impact whether in use or dropped
accidently, the helmet should be replaced. Cookie Composites generally recommends helmet replace-
ment every THREE years. Although this helmet provides some protection it cannot provide complete
protection from all foreseeable impacts. Please use responsibly

3. To make this adjustment, locate the RED label axed to the Anchor and pull this away from the cheek pad.
You can either shorten or lengthen the adjustment cord at the anchor depending on your requirements.
Shortening will make the rear skirt tighter on the back of you neck. Lengthening the cord will make the rear
skirt looser . Note that any adjustment should be made at the anchor and not at the strap buckle. After making
your adjustment lock the cord of acording to Figure 6. Tuck the anchor and excess cord into the channel
opening and pull the chinstrap to seat the anchor into position . Once adjusted properly the helmet will t
