Double Wrench Method - JLG G5-18A Service Manual

2.8.14

Double Wrench Method

To prevent undesired hose or connector rotation, two
wrenches must be used; one torque wrench and one
back- up wrench. If two wrenches are not used,
inadvertent component rotation may occur which
absorbs torque and causes improper joint load and leads
to leaks. For hose connections, the 'layline' printed on the
hose is a good indicator of proper hose installation. A
twisted lay-line usually indicates the hose is twisted.
