If Trouble Arises
Flat Tire
CAUTION
If the bottle is shaken after the injection
hose is screwed on, tire sealant could
spray out from the injection hose. Tire
sealant contacting clothing or other
objects may be impossible to remove.
Shake the bottle before screwing on the
injection hose.
NOTE
The sealant hardens easily and
injecting it will be difficult under cold
weather conditions (0 °C (32 °F) or
below). Warm the sealant inside the
vehicle to facilitate injection.
7. Remove the cap from the bottle. Screw
on the injection hose with the bottle's
inner cap left on to break the inner cap.
