OM2200 Warnings And Cautions - Section 22 Page 22-5 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 nec- essary in order to get an accurate reading. A decal plate is located on the frame near the left hoist cylin- der 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 Section L for additional instructions for using this procedure.
Warning decals are applied to both brake accumulators located inside the brake system cabinet behind the operator cab. These decals remind servicing technicians 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 disconnect switches on the right side of the front bumper to alert servicing technicians that before doing any welding on the truck, always disconnect the battery charging alternator lead wire and iso- late electronic control components before making welding repairs.
In addition, always disconnect the positive and negative bat- tery cables of the vehicle. Failure to do so may seriously dam- age the battery and electrical equipment. Always fasten the welding machine ground (-) lead to the piece being welded; attached as near as possible to the weld area nents.
