Tire Sealant
The kit contains a liquid sealant that when injected
into a flat tire, can temporarily repair nail holes
or cuts in the tread area of the tire. The tire sealant
cannot repair tire damage caused while driving
on a flat tire or a tire that has had a "blow out" or
a tire that has punctures in the sidewall areas.
The tire sealant solution is to be used for a single
tire and can only be used once.
Check the tire sealant expiration date on the
sealant canister. The sealant might not be
as effective beyond the expiration date. If needed,
see your dealer for a replacement canister.
Using the Tire Inflator Kit
To use the tire inflator kit, do the following:
1. Place the inflator kit on the ground and unwrap
the sealant filling hose from the compressor.
2. Remove the air compressor accessory plug
from the unit. To do this, pull the top portion
of the wrapped cord out first, then the bottom,
and then unsnap the plug. Do not insert the
plug into an accessory outlet yet.

3. Remove the valve stem cap from the flat tire
by turning it counterclockwise.
If an object, such as a nail, has penetrated the
tire, do not remove it.
4. Attach the sealant filling hose (A) onto the tire
valve stem. Turn it clockwise until it is tight.
Make sure the inflator kit on/off switch (B) is in
the O (off) position.
