D346, D348 & D349 VEHICULAR ENGINES Caterpillar

Perform required periodic maintenance before starting the engine. Make a "walk-around" inspection of the installation. It only takes a few minutes to correct minor discrepancies. This can prevent major repairs at a later date.

1. Inspect the air cleaner service indicator. If the red piston is locked in the raised position, service the air cleaner.

2. Inspect the coolant level. If two radiators are used, inspect the coolant level in both. Coolant level should be .50 inch (1 cm) of the bottom of the filler necks.

3. Measure the crankcase oil level. The oil level must be between the ADD and FULL marks on the dipstick.

4. Inspect the fuel level.
