Removal status
In the normal position (operating cylinder on the left, reserve cylinder
on the right), the following display will be seen:
– Status display (12) is green = gas taken from the left cylinder (oper-
ating cylinder).
– Status display (12) is red = gas is taken from the right cylinder
(reserve cylinder); check the connection and fill level of the left
cylinder.
Changing the gas cylinder
Use the included screw aid (9) to attach and remove the high-pres-
sure hoses (3). It will help you generate the necessary tightening
torque and will prevent damage to the union that may otherwise re-
sult from using an improper tool.
Residual gas: No smoking, no naked flames!
– Close the valve (1) of the empty gas cylinder (2).
– Remove the high-pressure hose (3) from the gas cylinder (2) and
remove the clip-on adapter, if present.
– Attach the high-pressure hose (3) to the full gas cylinder and fit the
clip-on adapter, if present. Change the filter pad of the gas filter.
