Starting shown with the FS 90

Step 1 of 14: Laying the brushcutter on the ground

Lay the brushcutter down 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.

Step 2 of 14: Pressing the throttle trigger lockout and the throttle trigger

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

Step 3 of 14: Setting the switch to START

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

Step 4 of 14: Starting throttle position

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

Step 5 of 14: Setting the choke shutter knob to Choke

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

Step 6 of 14: Pressing the primer bulb

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.

Step 7 of 14: Secure footing / pushing the brushcutter onto the ground

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.

Step 8 of 14: Pulling the starter rope

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.

Step 9 of 14: Engine fires briefly

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

Step 10 of 14: Pulling the starter rope again

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. If the brushcutter still will not start, contact your STIHL Approved Dealer. He will be able to advise and assist and help you solve any problems that may arise.

Step 11 of 14: Pressing the throttle trigger

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.

Step 12 of 14: Lifting up the brushcutter

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

Step 13 of 14: Off you go!

The brushcutter is now ready for use.

Step 14 of 14: Switching off the machine

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