Bleeding Pressure from System
If the hoses have been disconnected while under pressure, if one hose disconnects during
operation, or if the remote is depressed while not connected to cylinder, you will likely build
pressure in the system and will not be able to reconnect the hoses.
• Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard
by relieving pressure before disconnecting hydraulic lines. Use a piece of paper or card-board,
NOT BODY PARTS, to check for suspected leaks.
• Wear protective gloves and safety glasses or goggles when working with hydraulic and high-
pressure wash systems.
• If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may result.
Steps to take:
1)
Using two 7/8” wrenches, loosen each hose at the
2) female quick coupler. Drape a rag over this to prevent
3) getting sprayed with escaping fluid. Be Careful! Eye
protection is recommended. Hydraulic fluid may be
4) hot if the unit was recently cycled.
5) If you have completed this procedure, and the hoses will
still not connect, pressure must be present at the male.
The simplest method is to loosen the fittings at the hydraulic
cylinder. Be careful of escaping hydraulic fluid, and cover
with cloth during bleeding process.
6) Reconnect both quick couplers, and double check that
all fittings are tight before operation.
