Komatsu — WARNINGS AND CAUTIONS

OM2203 08/04 Safety - Section 22 Warnings and Cautions Page 22-5 High Voltage Danger Plates and Caution Plates are attached to the doors of the Electrical Control Cabi- net. The High Voltage Plate is also attached to the blown grid housing, extended range housing, rectifier housing, inlet duct structure and rear hatch cover. Before doing any welding on the truck, always dis- connect the positive and negative battery cables of the vehicle. Failure to do so may seriously damage the battery and electrical equipment. Disconnect bat- tery charging alternator lead wire and isolate elec- tronic control components before making welding repairs.

(It is not necessary to disconnect or remove any control circuit cards on electric drive HAULPAK® Trucks or any of the AID circuit control cards.) Always fasten the welding machine ground (-) lead to the piece being welded; grounding clamp MUST BE ATTACHED AS NEAR AS POSSIBLE to the weld area . Never allow welding current to pass through ball bearings, roller bearings, suspensions, or hydraulic cylinders. Always avoid laying welding cables over or near the vehicle electrical harnesses. Welding voltage could be induced into the electrical harness and possibly cause damage to components. This plate is mounted on the top side of the blown grid housings.

Stepping or standing here may result in serious personal injury. A wheel motor oil level decal is attached to the gear cover on both electric wheel motors. This decal stresses the fact that the truck must be on a level surface and parked for 20 minutes prior to checking the oil level. This is necessary in order to get an accurate reading. A decal plate is located on the frame near the left hoist cylinder which provides the operator or techni- cian with the hook-up procedure for dumping a loaded, disabled truck, by using a functional truck for hydraulic power. Refer to the Service manual for additional instruc- tions for using this procedure.
