Move the machine to a smooth, horizontal location that is away from operating machines and away from personnel.
Place the steering control lever in the NEUTRAL position.
Engage the parking brake.
Fully retract the counterweight.
Stop the engine.
Turn the key to the ON position, but do not start the engine.
Verify that the implement lockout switch is in the UNLOCK position.
Move the thumb wheel for the counterweight control to the EXTEND position. The counterweight should move outward to the neutral position.
Move the control levers through the full range of travel several times. This movement will relieve any pressure that may be present in the implement hydraulic system.
Make sure that the pressure in the entire hydraulic system has been released. Refer to the Operation and Maintenance Manual, "System Pressure Release" for the detailed procedure to release the system pressure.
