Komatsu — 4.7.6.e CHECKING THE TYRE PRESSURE

MAINTENANCE PLAN 4.7.6.d LUBRICATING THE FRONT AXLE JOINTS CENTRAL COUPLING The lubrication points (1) of the wheel joints are indicated in the figure and it is important to remember that they are located in symmetrical positions, while the central joint is lubricated by means of a grease nipple (2) positioned on the frame. The lubrication must be carried out after carefully cleaning the grease nipples, by applying the greasing pump supplied together with the machine and using the prescribed grease. (See “4.3 FUEL, COOLANT AND LUBRICANTS”). Once the lubrication has been carried out, remove the contami- nated grease that may have spread out of the joints and of the central coupling.

RWA03430 2 184 4.7.6.e CHECKING THE TYRE PRESSURE DANGER • Inflate the tyres only after positioning them in a protection cage. • To inflate the tyre, stand beside the external belt. • Do not exceed the pressures prescribed in chapter “5.1 TECHNICAL DATA”. DANGER • Inflate the tyres only after positioning them in a protection cage. • To inflate the tyre, stand beside the external belt. • Do not exceed the pressures prescribed in chapter “5.1 TECHNICAL DATA”. This check is indispensable to preserve the tyres, keep them ef- ficient over time and make them last longer. The correct pressures are indicated in the specifications. (See “5.1 TECHNICAL DATA”).

While checking the pressure, check also the conditions of the tread and sidewalls. RWA01680 RWA01680
