How to Start a Cut-Off Machine

Follow these tips on how to properly start your STIHL gasoline-powered cut-off machine.

Preparing

• Always read and follow the STIHL product instruction manual.
• Familiarize yourself with the location and function of the controls.
• Make sure fuel and oil caps are tight and that the cut-off machine is wiped clean.
• Inspect the unit to make sure nothing is missing, loose, or broken and that the cutting wheel is properly fitted.
• Always wear proper protective gear, designed and rated for your task, such as boots, chaps, gloves, eye protection, hearing protection, and a helmet.

Starting

• Place the machine on flat ground in a clear area. Make sure that the wheel is free from the ground and other obstructions.
• Depress the throttle interlock and throttle trigger at the same time and move the on/off switch to the start position. Release trigger and interlock.
• Set choke to the cold-start position, if so equipped (consult manual).
• Press the compression button.
• If equipped with a purge pump, depress it a minimum of five times.
• Use your right hand to grip and slowly pull starter handle until you feel slight resistance, then give a brisk, full pull.
• Repeat until you hear the machine burp or try to start.
• Again, push in the compression button.
• Move the choke to the warm position.
• Pull the starter handle using the same technique as before until the cut-off machine starts.
• Once started, squeeze the throttle lightly for 30 seconds to warm up the engine.
• If wheel turns at idle, adjust the idle screw as necessary. Do not use a machine that turns the wheel at idle.
• To stop the engine, move the on/off switch to the off position, making sure to wait for the cutting wheel to come to a complete stop.
