Caterpillar recommends a scheduled inspection of the alternator. Inspect the alternator for loose connections and proper battery charging. Inspect the ammeter (if equipped) during engine operation in order to ensure proper battery performance and/or proper performance of the electrical system. Make repairs, as required. Refer to the Service Manual.
Check the alternator and the battery charger for proper operation. If the batteries are properly charged, the ammeter reading should be very near zero. All batteries should be kept charged. The batteries should be kept warm because temperature affects the cranking power. If the battery is too cold, the battery will not crank the engine. The battery will not crank the engine, even if the engine is warm. When the engine is not run for long periods of time or if the engine is run for short periods, the batteries may not fully charge. A battery with a low charge will freeze more easily than a battery with a full charge.

NOTICE
All daily grease lubricant should be applied at the end of each machine operation while the machine is still warm and the asphalt is still soft or not set up. Failure to do so may allow asphalt to harden around the seals and risk damaging a seal and lead to premature bearing failure.
Illustration 1
Lubricate the two fittings for the outside bearings.
Note: Add lubricant only until excess lubricant is observed at each of the bearings.
Lubricate the two fittings for the inside bearings.
