or other damages of more than 1.5
mm depth on the housing.

Assembly of Shoulder Strap

Oxy K 30 S/AS (GB) and Oxy K 50 S/AS (K+S/PL)
To prepare the oxygen self-rescuer for use, mount the shoulder strap as
shown:
Looping the shoulder strap into the
back plate of the housing
Loop the short end of the shoulder
strap into the slot in the housing's
back plate (1).
Looping the shoulder strap into the
adjusting buckle
Thread the ends of the shoulder
straps into the adjusting buckles
and pull the ends of the shoulder
straps as far as possible (2).
Close the adjusting buckles(3).

Using the Oxygen Self-Rescuer

— Open the oxygen self-rescuer only in case of emergency.
If opened prematurely, the humidity of the ambient air could penetrate
the open oxygen self-rescuer and impair its function.
— Inspect the oxygen self-rescuer daily.
— Use the oxygen self-rescuer only once.
— To avoid risk of fire, make sure that no flammable materials (petrol,
grease, solvents etc.) can get into the oxygen self-rescuer before or dur-
ing operation.
There is also danger of ignition if the oxygen-releasing chemicals come
into contact with combustible substances such as coal when the oxy-
gen self-rescuer is damaged.
Opened units are classified as used and it is not allowed to store them.
They have to be disposed of (see "Disposal" on page 12).
For routine training purposes, use the training unit
Oxy K 30 DT/ET, Oxy K 50 ST or Oxy K 50 ST (PL) (see "Order List" on
