Installation Tips

Before you begin installing your new Supertop Ultra,

please read all the instructions thoroughly.

For a smooth t:

For easier installation, the top should be installed at a temperature above 72°F.
Below this temperature, the fabric may contract an inch or more, making it dif-

cult to t the vehicle.

It is normal for the fabric to contract and wrinkle when stored in the shipping
carton. Within a few days after installation, the fabric will relax and the
wrinkles will disappear.

WARNING

Do not rely in any way on the components of this
product to protect against injury or death in the event of an accident.

Never operate the vehicle in excess of manufacturer’s specications.

Read and follow, precisely, all installation instructions provided when
installing this product. Failure to do so may result in a poor t and could
place occupants of the vehicle in a potentially dangerous situation.

Safety glasses should be worn at all
times when installing this product.
