How do I start my Stihl ms170?

Why is my Stihl chainsaw so hard to start?

#1 Dirty carburetor

This is easily the top culprit. In fact, anytime I run into a chainsaw, string trimmer, lawn mower or other small engine that won’t start, is hard to start or runs poorly, I suspect a dirty carburetor first – and it’s usually the case. Gasoline begins to break down in as few as 30 days.

Should the brake be on when starting a chainsaw?

Check the Chain Brake

When engaged, the chain brake stops the chain from rotating around the saw’s guide bar. When using a chainsaw, you should always start it with the chain brake engaged so the chain does not move.

How do you start a chainsaw in the cold?

How do I get my engine to start in the cold?

“To start a car in freezing cold winter weather, start by shutting off any accessories, like the heater, radio and lights,” she said. Then, put the keys in the ignition, turn and hold the key for up to 10 seconds. If this doesn’t work, wait a minute or so before repeating the process.

How do you warm up a Stihl chainsaw?

How do I start my engine when its cold?

Why is it hard to start a cold engine?

Cold temperatures affect the chemical process inside the battery and reduce its ability to hold a charge. It also thickens engine oil, increasing friction in the starter motor and forcing it to work harder.

Why is cold start bad for engine?

Low temperatures cause engine oil to become more viscous, making it more difficult to circulate the oil. Air becomes more dense the cooler it is. This affects the air-fuel ratio, which in turn affects the flammability of the mixture.

Is it bad to cold start an engine?

Let’s put it together: cold starts are not bad for your vehicle. If you live in a more frigid region, your engine oil will likely cool out, which might initiate a cold start.

Is Revving after cold start bad?

Since the engine’s idle speed is higher during a cold start, how about revving it even higher to “help it along”? According to our engineer, this would be detrimental. You should let the engine warm up on its own. Revving the engine may hasten the warm-up process.

What is considered a cold start?

Cold Start means the start of an engine only after the engine oil and water temperatures are stabilized between 68 and 86 degrees F for a minimum of 15 minutes.

How long should you wait for a cold start?

Some drivers prefer to let the engine idle for 20 minutes or longer to get everything—including the cabin—really warm, but the fastest way to warm up an engine is by driving. Just remember not to rev the engine hard for the first few minutes of driving until you see the temperature gauge move off the cold reading.

Is cold start necessary?

Why is a cold start important? Getting into the technical side of things, a cold start not only lets your engine get up to temperature, but will also let the oil within get warmed up. Oil is a critical fluid in your motor as it keeps all the moving parts well lubricated and functioning optimally.

Does revving engine help heat?

Revving your engine will not make it warm up any faster, but it will subject your engine to increased stress before the oil has had the chance to circulate properly. You should also avoid accelerating too quickly until the engine has fully warmed up.
