Further boosting its performance is the STIHL Electric Motor, which stands out for its whisper-quiet operation and minimal vibration. Unlike its gas-powered counterparts, this motor requires virtually no maintenance, sparing you from the usual hassle of spark plug changes and engine cleaning. This makes the MSA 70 C-B not just easier to maintain, but also a pleasure to use, especially in residential areas where noise can be a concern.

Safety Features

With any chainsaw, user safety must come first, and the STIHL MSA 70 C-B excels in this department with several integrated safety mechanisms. One of the key features is the Throttle Trigger Interlock, which necessitates active engagement before the saw can operate, effectively eliminating the risk of accidental startups. This feature ensures that the chainsaw only runs when you are fully prepared to begin work, adding an essential layer of safety.

Another critical safety feature is the STIHL Quickstop chain brake. This innovative system is engineered to halt the chain almost instantly during a kickback, which is one of the most common—and dangerous—chainsaw mishaps. The quick activation of this brake can drastically reduce the risk of injury, providing peace of mind even during the most demanding tasks.


The convenience of the STIHL MSA 70 C-B is highlighted by its Quick Chain Adjuster (QCA), which allows for fast and tool-free chain tension adjustments.

The STIHL MSA 70 C-B stands out for its efficiency and environmental friendliness, making it an excellent choice for homeowners committed to sustainable practices. It’s slightly heavier than its competitors but offers innovative features like the Ematic™ Lubrication System which significantly reduces oil consumption and extends battery life, making it ideal for prolonged use in yard maintenance.

The Husqvarna 120i is the lightest of the three, which may appeal to users seeking a chainsaw that is easy to handle and maneuver. Its very low noise levels and intuitive control system make it a good option for casual, infrequent use in a residential setting.

The DeWalt DCCS620P1 offers great versatility and is suited for users who may already have other DeWalt tools. Its tool-free chain tensioning and bar tightening are significant advantages for users who prefer a hassle-free setup and maintenance. While it may not offer the same battery efficiency as the STIHL, it’s a strong contender for varied, medium-duty tasks.

Choosing the right chainsaw depends on your specific needs, including the nature of the tasks, preferred weight, noise tolerance, and loyalty to battery systems. Each of these models brings unique strengths to the table, catering to different preferences and requirements.

Maintenance Tips for STIHL MSA 70 C-B Cordless Chainsaw

Proper maintenance is key to extending the life and performance of your STIHL MSA 70 C-B Cordless Chainsaw. Here are some essential tips to keep your chainsaw running smoothly:

  1. Regular Cleaning:
    • Clean the air filter regularly to prevent dirt from entering the engine. A clean air filter ensures efficient operation and prevents premature engine wear.
    • After each use, clean the guide bar and chain to remove debris and sap. This prevents build-up that can lead to increased wear and tear.
  2. Chain Maintenance:
    • Check the chain oil level before each use and top up as needed. The Ematic™ Lubrication System will help distribute the oil evenly, but ensuring there is enough oil is crucial.
    • Keep the chain sharp for the best performance. A dull chain makes the chainsaw work harder, which can strain the motor and reduce battery efficiency.
    • Regularly check the chain tension. A chain that’s too tight or too loose can be dangerous and lead to poor cutting performance. Use the Quick Chain Adjuster for easy adjustments without tools.
  3. Battery Care:
    • To maximize battery life, charge the battery fully before first use and recharge only when it’s fully discharged. Avoid leaving the battery on the charger once it’s fully charged.
    • If you’re not using the chainsaw for an extended period, remove the battery and store it in a cool, dry place. This avoids battery drain and keeps the battery in good condition.
  4. General Inspections:
    • Regularly inspect the chainsaw for any signs of wear or damage, particularly the guide bar, chain, and battery contacts.
    • Before each use, check that all nuts, bolts, and screws are tight to ensure the chainsaw is structurally sound.
  5. Seasonal Storage:
    • When storing the chainsaw for the off-season, clean it thoroughly, lightly oil the chain and guide bar to prevent rust, and store it in a dry, secure place away from direct sunlight or extreme temperatures.


All in all, the STIHL MSA 70 C-B is a fantastic choice for any homeowner seeking a reliable, efficient, and easy-to-handle chainsaw.
