MAINTENANCE

Proper maintenance is recommended to help prolong the life of the vehicle and to avoid injuries to the operator. Check the stability of the handlebars and rear brake cables to ensure they are reliable before each operation. Brake cables may need adjusted after excessive use. The front tire should be maintained at 22PSI and the rear tires should be properly maintained at 22PSI. Under inflated or over inflated tires result in performance loss, tire wear, or even tire damage. The vehicle should always be kept in a clean condition and may require some cleaning after each use. Always use a clean soft cloth to wipe off any dirt or debris that you may have encountered while riding. Any moisture or rain should be wiped off prior to storage. Avoid operating the vehicle in rain or through water puddles. Avoid storage of the vehicle in moist areas or near corrosive gases, as they will corrode the metal. Proper maintenance will help prolong the life of the vehicle and make your riding experience more enjoyable. Never exceed the weight capacity of the go kart. Never carry a passenger if the vehicle is only designed for one person ride. Excessive weight may damage the vehicle and is very unsafe.
