Didn't last very long - 14 months

published

. From the instructions - It was very hard to start. Had to watch a blogger on U-Tube explain
. Only used it a few times and at 14 months the motor seized up
. The dealer said "no 2 stroke oil in petrol mix". I don't believe this was the case. The gas (petrol) in the tank was the right mix of oil and petrol- we both could see that. Maybe only Stihl 2 stroke oil should be used.
. Not sure I'd buy another Stihl 170.

Purchased in April 2019 at GYC for $250.00.

Please note -my review is NOT in any way to be a criticism of GYC - they are a very efficient and trustworthy dealer and I'll recommend them to anyone. My review is about my experience with my Stihl 170.

Not Happy

To hard to start. Followed all the instructions with the choke procedures and this thing still won't start. Had to make multiple trips to the dealer at ACE Hardware. When you can get it running, it does a decent job. Lost to much time with this saw running back to the dealer.

Very hard to start. Instructions incomplete.

published

Reading all the other reviews it seems that frequent users think it is great. Others, like me, have great difficulty getting it to start. I follow the instructions as best I can. Also there is a lever beside the word STOP just above the four position master control lever and two images of a padlock; one open, one closed. There is no mention of this lever in the manual. Do I move the lever towards the open padlock symbol to unlock it, or do I move the lever to reveal the open padlock symbol?

My previous chainsaw was electric. I forget the brand but it worked really well for many years. I got talked out of getting another electric one. Bad decision.

Bill, U-tube have some good videos on the best starting procedure. I suggest you take a look. They don't like stale fuel so it's best to drain the tank when not using it. My 170 seized up so I changed brand and paid a bit more for an Echo chainsaw. It's beautifully engineered, starts first pull and runs very smoothly (made in Japan too). I'm not longer a fan of Stihl although I do own a Stihl petrol blower which has been a great machine. It's old and not made in China.

Details

The MiniBoss series by STIHL presents an entry-level petrol-powered chainsaw, ideal for cutting firewood and felling small trees. It’s easy to start with a combi-lever and contains an automatic STIHL Ematic chain lubrication system.

Features

STIHL anti-vibration system: This anti-vibration system dampens the oscillations from the engine which significantly reduces vibrations at the handles, too, ensuring smooth operation of the chainsaw.

Compensator: This controller in the carburetor prevents the fuel-air mixture from getting richer as the air filter becomes clogged which keeps the fuel/air ratio in the combustion mixture constant. This also makes the engine power constant. The filter doesn't need to be cleaned until a significant drop in power occurs.

Single-lever master control: All the important functions such as start, choke, throttle and stop can be operated via a single lever.

STIHL Ematic-System: The Ematic chain lubrication system ensures pinpoint lubrication of the saw chain links and guide bar rails. When used with STIHL OILOMATIC saw chain, it will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%.

STIHL ElastoStart: STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user’s joints and muscles through a spring or rubber element in the starter handle.

Pre-separation air filtration system: The innovative long-life air filter system greatly extends the service life of the filter. Air routing removes larger particles of dirt, meaning the actual filter has less to do, and the saw can be used for longer without having to clean the filter.

Advanced combustion technology: Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower consumption and high torque across a broad rpm range.

QuickStop Chain Brake: The QuickStop chain brake is a protective mechanism when handling chainsaws. The chain brake is operated via the front hand guard and brings the saw chain to a standstill in fractions of a second. If the kickback is strong enough, the Quick Stop Chain Brake automatically releases.
