OM2025.2 Safety - Section 2 Warnings and Cautions Page 2-25 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 accu- rate reading. A decal plate is located on the frame near the left hoist cylinder which provides the operator or technician 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 instructions for using this procedure.
Warning decals are applied to both brake accumula- tors located inside the brake system cabinet behind the operator cab. These decals remind servicing techni- cians to be sure to close the accumulator drain valves after they have been opened to bleed brake pressure. It further warns not to over-tighten the drain valves to prevent damage to the valve seat(s). This CAUTION decal is placed near the battery discon- nect switches on the right side of the front bumper to alert servicing technicians that before doing any weld- ing on the truck, always disconnect the battery charg- ing alternator lead wire and isolate electronic control components before making welding repairs.
In addition, always disconnect the positive and nega- tive battery cables of the vehicle. Failure to do so may seriously damage the battery and electrical equipment. 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 pos- sibly cause damage to components.
