Install The Rear Wheels - Razor ScreamMachine Owner's And Safety Manual

Figure 2f.
Once the fork crown is firmly seated, loosen the adjusting screw
approximately 1/4 to 1/2 turn. This relaxes the preloading and allows the
steering to rotate without binding. Test by turning the handlebars to full
lock left and right. It should steer with slight friction and no binding or
tight spots.
NOTE: The steering bushings are designed for long life and
should require no maintenance. They do not require oil or any type of
"wet" lubrication. If the steering becomes rough, disassemble, inspect
and clean the bearing surfaces (soap and water is fine). Dry thoroughly
and reassemble. Although the bushings and thrust washers are self-
lubricating, a light application of a dry-lube can be used to facilitate the
anti-friction properties of the steering head bushings.
WARNING: Failure to properly install the handlebar to the fork
legs can result in the handlebars falling off and causing risk of injury.
Periodically check to make certain the adjusting screw is properly
tensioned and that the handlebars are securely attached to the forks.
Refer to the safety information in chapter 5 for additional details.
