Operating Procedures: Startup, Throttle, and Safety Interlocks

What happens here

Before operating the chipper, ensure the belt is disengaged. To start the engine, insert the key into the ignition on the control panel. First, preheat the glow plugs (indicated by a yellow warning light on the panel). Once preheated, press the green start button to activate the engine. The throttle is a twist-style knob; set it to approximately 25% for initial startup. After the engine is running, slowly release the belt engagement mechanism. This will cause the rotor to pick up speed. Bear Cat chippers are designed to run at wide-open throttle (all the way up) for optimal performance.

Goal: Learn the correct startup procedure, how to control the throttle, and utilize safety features.
