Pressure air can cause personal injury. When pressure air is used for cleaning, wear a protective face shield, protective clothing, and protective shoes.The maximum air pressure for cleaning purposes must be below 205 kPa (30 psi) .Fluid Penetration
Pressure can be maintained in the hydraulic circuit long after the engine has been stopped. The pressure can cause hydraulic fluid or items such as pipe plugs to escape rapidly if the pressure is not relieved correctly.Do not remove any hydraulic components or parts until pressure has been relieved or personal injury may occur. Do not disassemble any hydraulic components or parts until pressure has been relieved or personal injury may occur.Perform the following procedures in order to relieve pressure:
Lower the bucket or equipment to the ground.
Stop the engine.
With the operator in the seat, move the hydraulic activation control lever to the UNLOCKED position.
Actuate an equipment control lever about ten times in order to dissipate the pressure in the hydraulic circuit.Always
