particles may be in the airstream and could cause
injury.
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.
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.
Inspect the batteries and battery cables as follows:
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.
2.1 Be sure the battery holddown is secure. If it
is loose, tighten the hold-down bolts. If it is
broken, replace it.
CAUTION
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.
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.
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.
3.
Check the fluid level in the windshield washer res-
ervoir.
Add washer fluid as needed.
WARNING
Washer fluids may be flammable and poisonous. Do
not expose washer fluid to an open flame or any
