Assembly and preparation
Checking the gas cylinders
The pressure specifications are based on gas
cylinders of size E at 21 °C/70 °F. If the pressure in
a gas cylinder does not reach the recommended
minimum pressure (PSI - MIN), the gas cylinder
must be replaced by a full gas cylinder.
1
Open cylinder valves (A).
Make sure that the pressure gauges on the gas
cylinders indicate the appropriate pressure
recommended in the following table.
No hissing must sound when opening the cylinder
valves.
In this case, the connection is leaking. The gas
cylinder must be mounted again.
2
Close the cylinder valves again.
Maximum permissible dimensions of the gas
cylinders
Observe the following points:
– Do not exceed the maximum length of the gas
cylinder including the pressure reducer / pin-
index connection.
– The gas cylinders must not protrude over the
lower edge of the trolley (observe maximum
length of the gas cylinders).
– The O
2
cylinder must not be mounted on the
right side (looking from the rear).
