-We recommend the use of our CMS-2 or CMS-3 carbon monoxide alarm.
-The compressed air used must be free from oil and water.
5.2 Air volume, pressure and line length
To ensure that the operator is supplied with sufficient oxygen, the air supply should be between
130l/min and 190l/min.
The air indicator will be activated by the minimum amount, i.e. the flag will be raised if the amount is
higher and lowered if it is lower.
Only CE-approved supply lines with safety couplings should be used to connect the air filter and the reg-
ulating valve (see Section 11: Replacement Parts).
The
length of the line
between the filter and the control valve on the helmet must not exceed
40 m
. If it
is necessary to use a longer line, please contact the manufacturer to define suitable measures.
The pressure in the supply line must not exceed
8bar
.
6 Operation
Prior to operation, the helmet, breathing air line, air supply line, air intake and all connections
must be thoroughly inspected and cleaned of all dust and debris. The helmet suspension should
also be inspected and adjusted if necessary
(see 7.2 - Adjustments)
.
The following steps must be taken before operating the helmet:
(1) Air supply
* Start the compressor.
* Open the service valve to pressurise the air supply line.
(2) Check the air pressure.
Make adjustments at the air filter.
(3) Check the equipment.
* Protective equipment
* Helmet
* Breathing air supply
(4) Check for leaks and fit.
* Supply lines
* Connections
(5) Put on the equipment.
* Put on the hood.
* Put the helmet on, ensuring as far as possible that no blast media gets
