This advanced starting system is designed to make starting STIHL products easier. The specific system may vary by model, but in each case, a quick pull overcomes the engine’s compression to minimize the strength and effort required to start. Available on selected products.

MS 251 C-BE is rated 4.5 out of 5 by 237.
Rated 5 out of 5 by from Easy Start, Nice Feel, So Far So Good! I've only used my new MS 251 C-BE a couple of times so far. Very impressed with the easy start, and the balance and feel of the saw. I decided for my use to go with the higher end of the home owner line, and I think I made the right choice as I'll be doing a bit more firewood cutting than I initially expected. I worried that this saw might be too heavy but have found it very comfortable to use. I'd definitely recommend this saw to others.

Rated 5 out of 5 by from Great product, easy starting and with 18 bar perfect Had a medium tree (18 inch wide 20 foot tall) and with an 18 inch bar this Stihl ran almost non stop for 6 hiurs cutting everything with no issues. So to say I am happy is an understatement. Great product and great price.

Rated 4 out of 5 by from Wrong tool for the job. This saw is great, it is dependable and does exactly what it expected. The problem was me."I needed a stronger saw", and overestimated it's ability, as advertised. Therefore, I use this saw as often as posable. Anything bigger, I go bigger.

Rated 5 out of 5 by from This is a great saw! I have had a chance to use this saw to cut down 9 trees this passed week.. It starts well runs great and is hard working. I used it on spruce, locus, pine, apple and maple with no issues. Some of the trees were larger then the blade length and I had no trouble cutting them. The easy start is a blessing for us older folks. The tool less adjusting feature is also a supper feature.

Rated 5 out of 5 by from It's that easy, starts easy, easy to handle. After shoulder surgery on both shoulders I needed something that would start easy and not weigh alot. This is the perfect saw to maintain my 7 acres.

Rated 4 out of 5 by from Needs a little push Starting - 5 stars Ease of use - 5 starsPower in the pinch - 3 stars Brand new - 2 days old - never started. First couple of pulls - starts like a champ.Start cutting dead pine - runs o.k.Bogs and stops very easily. It's pine. It's dead. It's rotting with bugs. Stihl bogs down. Chain tensions are easy to do. Flip top oil and gas caps are awesome. I just don't get why it bogs down so fast. Almost afraid to put it to hard wood. I am STIHL very pleased with the product in general. Keep up the good work
