CIRCUIT BREAKER PANEL

The machine is equipped with (3) resetable circuit breakers to protect machine from damage, (labeled as brush, main and drive). They stop current flow when circuit overload occurs. Once a circuit breaker has tripped, determine problem, let motor cool down and manually reset breaker by pressing circuit breaker button. The vacuum motors are thermally protected and will automatically shut–off when an overload occurs. The main and drive circuit breakers are designed so you can stop current flow by manually pulling out circuit breaker buttons. Pull out the main circuit breaker button when servicing machine or when machine is left unattended. Circuit breaker buttons are located at rear of machine as shown (Figure 15).
