g300 grinding visor
First use
Before using a new product, always check that the equipment is complete and that no damage
occurred during transport.
Filtered air is blown to Head tops from above. The correctly put on head top tight to the face ensures,
in a combination with the flow of supplied air, creating a slight overpressure in the face space, which
prevents dust and other contaminants from entering the user's respiratory zone.
Read these Instructions for Use carefully and follow them.
• The user must be familiar with the correct use of personal protective equipment.
• The user must know the type of contamination and its concentration in the ambient air.
• The oxygen concentration in the surrounding of a person using the filtration system must
not drop below 17% in Europe. In the Netherlands, Belgium, UK, Australia, and
New Zealand it must not drop below 19%. For the other countries obtain their requirements.
• Do not use the visor in explosive environments.
• Follow the instructions of the PAPR system and the filters.
• Only use the grinding visor with the PAPR system switched on. Filters must not be
connected straight to the visor!
• The filtered air overpressure inside the protective head top is the primary protective
factor preventing the ambient air contaminants from penetrating. In the case of PAPR
systems in combination with the visor, the protection of respiratory organs with the fan
switched off is low or none. Also, the carbon dioxide concentration may increase and
the oxygen content may decrease inside the visor.
• To put the hoods on comfortably, they have an adjustable headband (straps).
• Make sure that the sealing line of the head top fits tightly to the face (in hoods, tightness can
be adjusted using the self-tightening clamp under the chin). Only then may the perfect
protection level be secured.
• The protection factor may be reduced if the user has hair or beard extending to the
face sealing part. If it gets to the sealing line, the penetration will increase and the
protection provided by the system will decrease.
Cleaning and Disinfection
• Every time you finish your work, clean the headtop, check its individual parts and
replace damaged parts.
• Cleaning must be carried out in a well-ventilated room. Avoid inhaling harmful dust
settled on individual parts!
• For cleaning, use tepid water (up to +40°C) with soap or some other non-abrasive
detergent and a soft brush.
• Do not use agents containing solvents for cleaning.
• After individual parts have been cleaned with a damp cloth, they must be wiped dry or left
to dry at the ambient temperature.
Maintenance, Spare Parts Replacement, and Cleaning

Material:
• Forehead protection – polypropylene
• Visor – polycarbonate
• Face seal – polyamide floated with PU and PVC

Face seal replacement:
Removing the face seal:
• Release the face seal from the velcro fasteners on the headband.
• Tear the face seal off the velcro fastener on the visor and on the front part of the air duct.
• Carry out this operation carefully so as not to unstick also the velcro fastener.
Insert the face seal:
• Start in the middle of the lower edge and proceed symmetrically upwards fastening the
face seal edge to the velcro fastener along the entire circumference.
• Fix the face seal to the air duct.
• With the velcro fastener fix the face seal to the headband.
• Check that the face seal fits well along the entire circumference and that there are no
holes caused by folds on the face seal.
Setting the distance of visor to face
• Unlock the headband from the fixed position.
• Take out the grey pin on both sides of the visor.
• Set the optimum distance to chin (4 positions).
Setting the depth of headband
• Set the optimum depth using the pins on the top part of the headband.
Setting the circumference of headband
Push and turn the knob on the rear side of the headband.
• Adjust the circumference so that it is not too tight or loose.
Visor replacement:
Taking the visor out:
• Pull at the visor edge in the lower part.
• At the same time push from the lower inner side of the visor out.
Mounting the visor:
• Fix the lower part of visor into the provided opening.
