Pretrip Inspection and Daily Maintenance particles may be in the airstream and could cause injury. CAUTION 1.2 Exhaust the remaining air and moisture from the system by opening the drain cocks on the bottoms of the remaining air reservoirs. Block the valves open. Take care to keep the vent plugs tight so that the neutralizing solution does not enter any of the bat- tery cells and damage the battery. 1.3 Water and oil emulsion often form pockets which will not drain while compressed air is in the reservoirs. Because of these pockets, leave the valves blocked open during the first part of the pretrip inspection. 2.2 Remove any corrosion from the hold-down and the top of the battery.
Use diluted am- monia or a soda solution to neutralize the acid present, then rinse off the ammonia or soda solution with clean water. 2. Inspect the batteries and battery cables as follows: If the battery posts or cable terminals are corroded, disconnect the terminals from the posts. Clean them with a soda solution and a wire brush. After cleaning, connect the ter- minals to the battery posts, then apply a thin coat of petroleum jelly or dielectric grease to the posts and terminals to help retard corro- sion. WARNING Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm.
To prevent possible per- sonal injury, always wash your hands after handling battery parts and related accessories. 3. Check the fluid level in the windshield washer res- ervoir. Add washer fluid as needed. 2.1 Be sure the battery holddown is secure. If it is loose, tighten the hold-down bolts. If it is broken, replace it. WARNING Washer fluids may be flammable and poisonous. Do not expose washer fluid to an open flame or any 9.4
