How to Start a Stihl Ms 250 Chainsaw

To start a Stihl MS 250 chainsaw, first make sure the saw is on an even, flat surface. Then check that the chain brake is engaged by pressing down firmly on the front handle. Place your right foot against the rear handle and grip it with your right hand while pulling out the starter cord with your left hand until you feel resistance.

Push down gently on both handles to unlock the throttle lock and then pull sharply to engage it. Give one full pull of the starter cord and if nothing happens, move the choke lever up two clicks for cold starts or just one click for warm starts. Once done, give another full pull of starter cord until engine fires up then set choke lever back to its original position when engine runs smoothly before finally releasing chain brake after adjusting speed control knob accordingly.

  • Prepare the chainsaw: Unpack your Stihl MS 250 Chainsaw and lay it on a flat surface
  • Check to make sure all parts are present, including the bar oil tank, chain brake handle, starter rope handle, choke lever and throttle trigger
  • Fill the fuel tank with fresh unleaded gasoline: Remove the gas cap from the top of the saw’s fuel tank and pour in two-stroke engine oil (Stihl recommends using its own brand of oil)
  • Add one quart of fresh unleaded gasoline into the fuel tank then replace and tighten up the gas cap securely
  • Attach guide bar & chain to saw body: Fit both ends of guide bar into slots located at front end of housing unit and secure it with screws provided with kit
  • Pull out retainer pin located behind sprocket cover so you can remove it exposing clutch drum drive sprocket which holds cutting chain onto saw body
  • Insert new cutting chain over drive sprocket ensuring that cutters face away from direction for which rotation takes place when operating chainsaw (to outside)
  • Reinsert retainer pin back into position after attaching cutting chain around drive sprocket properly then put back cover plate over clutch drum/drive sprocket assembly once finished fitting new cutting chain around drive sprocket correctly
  • 4
  • Start up chainsaw: Set On/Off switch to “On” Position then move choke lever to closed position followed by moving throttle trigger half way between idle speed setting & full load rpm setting (full open)
  • Pull starter rope slowly until resistance is felt then give firm pull till engine starts running before releasing starter rope quickly letting recoil spring take care of rest while returning automatically to starting point thus rewinding itself ready for next start up attempt if required

Is a Stihl Ms250 And Easy Start?

Yes, the Stihl MS250 is an easy start chainsaw. It is equipped with a quick-starting inertia-activated chain brake and features a decompression valve for easier starting when cold. The advanced anti-vibration system also reduces fatigue during extended use, so you can work longer without feeling fatigued or sore.

Additionally, the lightweight design makes it easy to maneuver and handle for even novice users. With all of these features combined, it’s no surprise that this chainsaw has become such a popular choice among homeowners and professionals alike!

Is There a Trick to Starting a Stihl Chainsaw?

Yes, there is a trick to starting a Stihl chainsaw. The key is to ensure you have the right fuel-to-oil ratio and that the air filter and spark plug are clean before attempting to start it. To begin with, make sure your saw has fresh gas in the tank.

This should be mixed with 2-stroke oil at a 50:1 ratio (50 parts gasoline to 1 part oil). It’s best to use fresh fuel since any old gasoline can cause damage or difficulty starting. After this step has been completed, check if the air filter is clean or needs replacing – if it looks dirty then replace it for optimal performance.

Finally, check if the spark plug wire connection is secure; if not tighten it up using an appropriate wrench size for your model of chainsaw. Once all these steps are taken care of you’re ready to go! Just remember always read your owner’s manual carefully before operating any power tool as safety comes first!

How to Prime Ms250?

To prime an MS250 chainsaw, you need to begin by opening the fuel cap and adding fresh gasoline. It’s important to use a fresh tank of gas as old gas can clog up the engine and cause it to run poorly or not start at all. The next step is to place the choke lever in the “Choke” position, then pull out and depress the primer bulb four times until it becomes firm.

This should be done with both hands while maintaining pressure on the handlebar trigger switch so that fuel will flow down into your carburetor. Finally, turn on your saw by engaging its throttle control and then pulling sharply on its starting cord until it starts running smoothly. With these steps completed, your MS250 chainsaw is now primed for use!

How Do You Unflood a Stihl Ms250 Chainsaw?

To un-flood a Stihl MS250 chainsaw, first be sure to turn off the fuel valve. Next, remove the air filter and spark plug. Using either a small vacuum cleaner or an aerosol can of starting fluid, spray some into the spark plug hole.

Re-install both components, then pull out your recoil starter handle several times until you hear it trying to start. Finally, switch on the fuel valve and try to start your chainsaw again! If that doesn’t work, repeat these steps up to three times before calling a professional for assistance.

If starting does not occur after several pulls, repeat priming steps again.

How to Start a Stihl Chainsaw Without Flooding It

A Stihl Chainsaw is a great tool to have for cutting down trees, but it can be difficult to start without flooding it. To prevent this from happening, make sure you use the correct fuel-oil mixture and properly prime the carburetor before starting the engine. Additionally, avoid pushing the choke all of the way in as that can cause too much gas to enter into the engine and lead to flooding.

Once everything is ready, pull on the starter cord slowly until you feel resistance then give it an extra strong tug and your chainsaw should start up!
