WATER LEAKAGE
Weep holes and locations are identified on the illustrations on Pages 64-65.
Note: Seal leakage is normal during intensifier operation. This normal leakage can start soon after new seal installa
-
tion, and does not damage intensifier components. A seal has failed and must be replaced only when the cutting
performance becomes unacceptable due to the drop in UHP water pressure caused by the seal leak.
