SERVICE MANUAL
3.7.4.1 REPAIRING TORN AREAS WITH PATCHES
Patches should stretch for at least 40 mm beyond the perimeter of the damaged part. For instance, if the hole is
40 mm, the patch should have a diameter of at least 120 mm; if a straight tear is 100 mm long, the patch should
be at least 180 x 80 mm. Complex tears should be treated as holes by taking the characterizing dimension of
the tear as diameter of the hole.
WARNING: THE SHAPE OF THE PATCHES SHOULD BE CIRCULAR OR RECTANGULAR
WITH ROUNDED CORNERS.
3.7.4.1.1 Fitting the patches
Proceed as follows:
1.
Cut a patch of suitable dimensions.
2. Prepare and clean the area to be repaired as described in 3.7.2..
3. Spread the glue as described in 3.7.3.
4. Place the patch making sure you remove all the air bubbles with a spattle. For major repairs use an inner
patch as well.
5.
After at least 12 hours, test the repair by inflating the part and checking that there is not pressure drop.
WARNING: THE REPAIRED AREA SHOULD NOT INCLUDE ANY WELD OF THE INFLATABLE
PART, AS GLUEING CAN NOT GUARANTEE TIGHTNESS ON THE STEP FORMED BY THE
WELD AND THE BUTT STRAP.
If the tear is near a weld do not repair and send the liferaft to the Manufacturer.
