How to Start up A Petrol Strimmer

Before starting a brushcutter, ensure that you have safely prepared the working area. Then take time to carefully read the instruction manual supplied with your machine, paying particular attention to any safety instructions. 

Please note: These instructions are based on starting up the FS90 model but similar steps will apply to alternative models. The instructions are supplementary to the information provided in your instruction manual and the pictures are visual guides only - different brushcutter models will have different controls so you must familiarise yourself with your own machine before starting it up. 

Starting up a Brushcutter

  1. Lay the brushcutter on the ground in a safe position on the ground. It should rest on the support on the engine and the cutting attachment guard. Make sure that the cutting attachment is not touching the ground or any other object as it may start to rotate when you start the engine. Keep everyone else at least 15 m away from the machine. Make sure you have a steady footing. 

  2. Press first the throttle trigger lockout and then the throttle trigger. Hold down both levers. 

  3. Push the switch on the multi-function control handle to the START position and keep it in that position. 

  4. Release the throttle, slide control and throttle trigger lockout again one after other. The machine is now in the starting throttle position. 

  5. When the engine is cold the choke shutter must be closed. Move the choke lever into the corresponding position to close it. 

  6. Push the primer bulb down at least 5 times, even if it is still full of fuel. This reduces the number of pulls required to start the engine, making starting easier. 

  7. Make sure you have a secure footing and check once again that the brushcutter is lying in a secure position. Push the machine down onto the ground so that it cannot tilt when starting. Check that the cutting attachment is not touching anything. 

  8. Slowly pull out the starter grip with your right hand until you feel it reach the first stop. Then pull the starter grip briskly and strongly upwards, keeping it as vertical as you can. Take care not to pull the rope all the way out. Do not allow the starter grip to spring back. Instead, guide it back in the opposite direction, to allow the starter rope to rewind correctly. 

  9. When the engine fires or after the fifth pull, move the choke shutter lever to open the choke. 

  10. Pull the starter rope again. The engine will fire. Note: If your brushcutter fails to fire, refer to your Instruction Manual to make sure you are following the correct procedure. 

  11. As soon as the engine is running, briefly touch the throttle trigger. The switch will move into the operating position (Position I). The engine idles. The tool stops rotating. 

  12. Slowly lift up the brushcutter, taking care not to touch the throttle trigger, unintentionally accelerating the machine.  

  13. The brushcutter is now ready for use. 

  14. Slide the switch on the multi-function control handle in the direction of the arrow on the stop symbol to STOP-O.
