General Maintenance And Cleaning - MARTINDALE M26/400 Bedienungsanleitung

Adjust the vertical position at which the hoses are held together such that when placed over the head the hose assembly does
not slip down over the shoulders. Ensure hoses are not twisted when placed over the head. Fit the full face mask according to
the specific instructions supplied with the mask. Connect the twin air hose to the full face mask by screwing the threaded nut
into the full face mask tightly by HAND.
Inspection & Fit Testing of System
BEFORE USE, THE FOLLOWING CHECKS SHOULD BE CARRIED OUT:
Leak Tightness Testing of Unpowered Apparatus
(With the facemask, double hose, belt bracket donned and reinforced hose fitted)
Block the strainer end of the air supply hose and inhale. This should create a negative pressure inside the mask, thus sucking
the mask onto the face. If this effect is not obtained, re-fit mask and check security of hose connectors then re-test.
Leak Tightness Testing of Powered Apparatus (
With the facemask, double hose with o/f valve, belt bracket donned and reinforced hose fitted)
Disconnect the turbine end of the main air supply hose, block and inhale. This should create a negative pressure inside the
mask, thus sucking the mask onto the face. If this effect is not obtained, re-fit mask and check security of hose connectors then
re-test. If supplying twin users this test should be carried out by both users.
