by JEREMY HIPA 22 Aug 2022 0 Comments

As one of the most popular chainsaws among homeowners, STIHL MS 170 plays a significant role in garden maintenance. Even if there are so many people having this saw, there are still some designs that can be upgraded to facilitate daily use.

1.Tensioner and Bucking Spike Upgrade

Tensioner

The chainsaw tensioner makes sure the correct and necessary tension of the chain. The chain tension mechanism in STIHL MS170 is normally located in the gap between the guide bar and the bucking spike. There are some homeowners complaining this is really a pain when it comes to chain tension adjustment. Thanks to there is another placement in STIHL MS170 chainsaw to install a new tension mechanism, we can make it an upgrade:
STEP 1: You need to take off the chain and the bar carefully and clean up the machine if necessary.
STEP 2: Now you can pull the mechanism forward, and wiggle it back and forth to remove the tensioner.
STEP 3: Then slide the new tension mechanism into the machine as well as a little clip. And screw in a metal screw aside the mechanism.
STEP 4: Screw up the tensioner. If your screw is plastic, don’t screw rather hard to avoid cracking or stripping.

Bucking Spike

Chainsaw spikes help to stabilize the saw when cutting through tough material, such as thick tree branches. The original one that comes with Stihl MS170 is too short to use efficiently when cutting tough wood. So considering the cutting safety and the cutting performance, it is necessary to upgrade the bucking spike.

2.Guide Bar and Chain Upgrade

Chainsaw undergoes tough situations like cutting, spinning, and bearing heat due to heavy objects. The guide bar and chain will be worn and torn over time, so changing a new bar and chain in time can help to improve cutting efficiency. If you find the old bar and chain have been worn out or working inefficiently. It is time to upgrade the chainsaw with a guide bar and a new OEM quality aftermarket chain.
A new guide bar and chain improve the cutting efficiency by about 16%.
