STIHL ON OFF SWITCH FULL
Next, you can then release the levers and set a full choke if the machine is cold. With both levers held down, you must then move the power switch to the “on” position. Once you’ve ensured that your trimmer has enough gas, you have to press and hold the throttle trigger interlock and the throttle trigger itself. The process of starting a combustion trimmer has a few extra steps… You then disengage the switch to cut off power. So, when starting an electric trimmer, you engage the switch, press the starting lockout lever, and squeeze the trigger.
Switching to the line (or “1”) completes the electric circuit which allows the trimmer’s motor to run (for electric trimmers) or sends power to the spark plugs in the engine (for combustion trimmers). What Does The Switch ON A Trimmer Do?Ī trimmer switch (aka “kill switch”) does pretty much what an on-off switch does…it turns the machine on or off. Of course, a shoddy repairman or two may have replaced some switches the wrong way around, but such is life. In fact, IEC standards dictate this, so it’s extremely unlikely for any manufacturer to err on what is a pretty basic thing. With these switches the line almost always represents “on” and the circle means “off”. In computer language (so to speak…no pun), 1 represents a positive value (“yes” or “on”) while 0 represents a neutral or negative value (“no”, “off”, “ignore”, etc.). The separate line and circle are also derived from the equally famous “stand-by” symbol, which features a line in an incomplete circle.Ĭomputer-oriented thinkers tend to interpret the symbols as a 1 and a 0 due to similarities with binary computing. The symbol is officially regarded as “line and circle”, mainly to bypass potential language and regional barriers of the more literal “on/off”. Well, according to the International Electrotechnical Commission (IEC), it’s neither. While starting or shutdown sequences may vary across individual machines, pretty much every Stihl machine we can think of has an on-off switch.Īnd pretty much all of these switches feature the same pair of symbols… “I” and “O”. 4 The Final Touches On A Stihl On/Off Switch… Stihl On-Off Switch Symbols.2 What Does The Switch ON A Trimmer Do?.
