Waste Disposal
Motor Oil Disposal

the environment. Dispose of used oil at a certified
recycling center or according to your state and local
regulations.

DANGER
Battery electrolyte contains sulfuric acid,
which is poisonous and can cause severe
burns. Swallowing electrolyte can be fatal or
if it touches skin can cause severe burns.
• Wear safety glasses to shield eyes, and
rubber gloves to protect skin and clothing
when handling electrolyte.
• Do Not swallow electrolyte.
Federal law states that batteries should not be placed
in the garbage. Management and disposal practices
must be within relevant federal, state, or local laws.
If a battery is being replaced or if the unit containing
the battery is no longer operating and is being
scrapped, take the battery to a local certified recycling
center. If no local recycling is available return the
battery to any certified battery reseller.
