WARNINGUse tongs or welding gloves when handling heated components. Failure to follow these instructions will result in personal injury.
CAUTIONBearings (1) are installed using a Bearing Heater (2). Use only a bearing heater/hot plate and follow manufacture's instructions. Heat components to 100 - 149 Celsius (212° Min. - 300° Max Fahrenheit). Never use an open flame to heat components. Never leave components on heater for an extended amount of time. If component is discolored after heating, the component has been overheated and must not be used. Failure to follow these instructions will result in component damage.
