Relieving System Hydraulic Pressure

Completely relieve system hydraulic pressure before breaking any hydraulic
connection or seal. Refer to the melter‐specific product manual for
instructions on relieving system hydraulic pressure.
De‐energizing the System
Isolate the system (melter, hoses, applicators, and optional devices) from all
power sources before accessing any unprotected high‐voltage wiring or
connection point.
1. Turn off the equipment and all auxiliary devices connected to the
equipment (system).
2. To prevent the equipment from being accidentally energized, lock and
tag the disconnect switch(es) or circuit breaker(s) that provide input
electrical power to the equipment and optional devices.
NOTE: Government regulations and industry standards dictate specific
requirements for the isolation of hazardous energy sources. Refer to the
