Cylinder Pressure Release
De-pressurize the hydraulic system. Refer to unit maintenance procedure 5-118.
Locate the cylinder pressure release fitting (2).
Fit an allen key wrench to the cylinder pressure release fitting (2) and then place a clean
cloth over the allen key wrench. Hold the cloth in place with one hand and turn the allen
key wrench with the other hand until the pressure is released. This will prevent hydraulic oil
from being sprayed.
Place a suitable container under the wrench to catch any excess hydraulic fluid.
Turn the allen wrench 180 degrees counter clockwise.
When the pressure is released tighten the cylinder pressure release fitting by turning the
allen wrench clockwise.
Clean up any spilled hydraulic fluid.
