CAUTION:
 Wear safety equipments appropriate to the job such as a hard hat, gloves and protective shoes.
 Sufficiently illuminate the work site and work under well-lighted area. Work under low light condition can
lead misoperation.
 Take care not to allow grease to contact with skin. If grease contacts with skin, wash away with a lot of water
and soap.
 Severe burns may result if skin comes in contact with hot parts immediately after operation. Before starting
to work, stop the engine and make sure all parts have sufficiently cooled down.
 When checking or servicing the machine by using the cab tilting function, tilt up the cab with the cab tilting
device. Thoroughly read this manual before operating the cab tilting device. Incorrect operation may cause
cab falling, possibly resulting in serious accident.
