CAUTION
Do not connect the electric air pump
connector to the cigarette lighter sock-
et or another 12 V socket. These are
not designed for operating the electric
air pump.
!
CAUTION
Do not run the electric air pump for
more than 20 minutes without a break,
otherwise it may overheat.
The air pump can be used again once it
has cooled down.
iDo not pull the valve core extractor
from the tire valve while the valve core
is unscrewed from the tire valve. Tire
sealant could otherwise escape onto
your hands.
The tire sealant is water soluble. If tire
sealant escapes, you can wash it away
with water.
