PRECAUTIONS FOR CAB TILTING

• Do not start the engine or unlock the PPC lock lever when the cab and riser are tilting.
• Do not enter the cab when the cab and riser are tilted.
• Do not tilt the cab and riser assembly when the machine is on a slope.
• Do not tilt the cab and riser assembly in windy conditions.
• When the tilt operation is being performed, ensure that the work equipment is in an extended position so

that there is no chance of interference between the work equipment and the cab and riser assembly.
