PRESSURE TEST
WARNING
· Never disconnect any hydraulic hose while

after engine is shut off for pressure to drop.
· Before testing hydraulic system with
hydraulic systems tester, load valve must be
open.
· If pressure raises rapidly or appears to be
uncontrolled during the test, open load valve
immediately.
· Failure to comply may result in injury to
personnel.
