2. Open both shoulder straps:
Press the adjusting clamp upwards with your thumb and

hang the breathing hoses over the protective cover.

closed-circuit breathing apparatus.
Meaning
The test has been completed
successfully.
An error has occurred.
Do not use the closed-circuit
breathing apparatus. Check
once again that the closed-
circuit breathing apparatus is
functioning correctly or have
the device serviced by
Dräger or trained experts.
Battery warning 1
A long warning tone sounds
at the same time.
With normal use of the Body-
guard, the closed-circuit
breathing apparatus remains
fully functional for up to
4 hours. To ensure safe us-
age, the battery should be re-
placed, however.
Battery warning 2
At the same time, 5 short
alarm tones sound and the
red LEDs flash.
The Bodyguard automatically
powers off and any further
operation is impossible.
The battery must be replaced
before before any new opera-
tion.
5. Lift the closed-circuit breathing apparatus over your head,
position your head between the breathing hoses (figure A)
and allow the closed-circuit breathing apparatus to drop onto
your back until the shoulder straps are positioned on the
shoulders.
6. Uniformly pull down and tighten the shoulder straps so that
the padding on the waist belt rests on your hip (figure B).
7. Close the waist belt and adjust the width.
8. Pull the ends of the belt until the closed-circuit breathing
apparatus rests firmly on your hips.
9. Insert the ends of the belt in the loops on the right and left-
hand sides.
10. If required, loosen the shoulder straps slightly until
comfortable.
11. Check the position of the three reinforcing rings on the
breathing hoses and readjust if necessary: Fix the middle ring
with the hose support centrally on the shoulder. The other
reinforcing rings should also rest on the shoulder.
CAUTION
!
When carrying heavy loads on the shoulder, the
breathing hoses may be squeezed thus interrupting
the breathing circuit.
For this reason, the reinforcing rings must be in the
correct position during use as well.
12. If the closed-circuit breathing apparatus has a connecting
piece with condensate trap, ensure that the sealing plug is
screwed securely into the connecting piece.
13. Fasten the full face mask.
14. Remove the sealing cap from the connecting piece, breathe
in deeply and hold your breath.
