Stihl MS 193 Top Handle Saw Review (Best for Arborists?)
Okay, here’s the deep dive into the Stihl MS 193 T, tailored for the discerning arborist and anyone else considering this top-handle chainsaw. I’ll be sharing my experiences, hard-earned lessons, and some insider knowledge you won’t find in the typical brochure.
The Arborist’s Secret Weapon: Unveiling the Stihl MS 193 T
Let’s talk chainsaws. Everyone knows Stihl, but the MS 193 T? It’s often overlooked, a bit of a “best-kept secret” in the arborist world. I’ve spent years felling trees, pruning branches, and bucking firewood, and I’ve learned that having the right tool can make or break a job. The MS 193 T, with its top handle design, is a specialized tool, and when used correctly, it’s a game-changer. However, it is essential to understand that this saw is exclusively for trained professionals. The top handle design makes it inherently more dangerous for untrained users.
Why All the Fuss About Top-Handle Saws?
The primary advantage of a top-handle chainsaw like the MS 193 T is maneuverability. Imagine yourself 20 feet up in a tree, straddling a branch, trying to make a precise cut. A conventional rear-handle saw becomes unwieldy very quickly. The top handle allows you to operate the saw with one hand, providing the necessary reach and control in tight spaces. This is critical for arborists who need to navigate complex tree structures.
My First Encounter: A Lesson in Respect
I vividly remember my first experience with a top-handle saw. I was green, eager, and probably a little overconfident. I was tasked with removing some dead limbs from an old oak tree. I thought, “Chainsaw is a chainsaw, right?” Wrong. The top handle’s responsiveness took me by surprise. The slightest wrist movement translated into significant saw movement. It was a wake-up call – a reminder that these tools demand respect and proper training.

Wood Selection: Matching the Saw to the Task
The MS 193 T is best suited for specific types of wood and tasks. It’s not a heavy-duty felling saw; it’s designed for precision work.
Hardwoods vs. Softwoods
- Hardwoods (Oak, Maple, Hickory): The MS 193 T can handle hardwoods, but it’s best suited for smaller branches and limbs (up to 8 inches in diameter). Attempting to cut larger hardwood logs will strain the saw and significantly reduce its lifespan.
- Softwoods (Pine, Fir, Spruce): The MS 193 T excels at cutting softwoods. Its lighter weight and maneuverability make it ideal for pruning and limbing softwood trees.
Wood Moisture Content: The Firewood Factor
When preparing firewood, wood moisture content is critical.
- Green Wood: Wood that has been freshly cut has a high moisture content (50% or higher). It’s difficult to burn and produces a lot of smoke. The MS 193 T can cut green wood, but it will require more effort and the chain will dull faster.
- Seasoned Wood: Wood that has been air-dried for 6-12 months has a lower moisture content (20% or less). It burns more efficiently and produces less smoke. The MS 193 T is ideal for cutting seasoned firewood.
Data Point: The ideal moisture content for firewood is between 15% and 20%. Using a wood moisture meter is a reliable way to determine if your firewood is properly seasoned. I’ve found that splitting the wood also helps it dry faster.
Log Dimensions: Staying Within Limits
The MS 193 T’s cutting capacity is limited by its engine power and bar length.
- Maximum Log Diameter: I recommend limiting the MS 193 T to logs with a maximum diameter of 12 inches, and even that is pushing it. For optimal performance and longevity, stick to logs under 10 inches.
- Cord Volume: A standard cord of firewood is 4 feet high, 4 feet wide, and 8 feet long (128 cubic feet). The MS 193 T is well-suited for processing smaller quantities of firewood, but for larger volumes, a more powerful saw is recommended.
Tool Calibration and Maintenance: Keeping Your Saw Sharp
Proper calibration and maintenance are essential for maximizing the MS 193 T’s performance and extending its lifespan.
Chain Sharpening: The Key to Efficient Cutting
A dull chain is not only inefficient but also dangerous. It requires more effort to cut, increases the risk of kickback, and puts unnecessary strain on the saw’s engine.
- Frequency: I recommend sharpening the chain after every 2-3 hours of use, or more frequently if you’re cutting dirty or abrasive wood.
- Tools: You’ll need a chainsaw file, a depth gauge tool, and a vise to hold the chain securely.
- Technique: Follow the manufacturer’s instructions for chain sharpening. Maintain the correct filing angle and depth to ensure optimal cutting performance.
Pro Tip: Invest in a chain sharpening kit. It includes all the necessary tools and a guide to help you maintain the correct angles.
Carburetor Adjustment: Fine-Tuning Performance
The carburetor controls the air-fuel mixture that enters the engine. Adjusting the carburetor can optimize the saw’s performance and fuel efficiency.
- Idle Speed: The idle speed should be set so that the chain does not move when the engine is idling.
- High-Speed Mixture: The high-speed mixture should be set to provide optimal power without causing the engine to overheat or stall.
- Low-Speed Mixture: The low-speed mixture should be set for smooth idling and acceleration.
Caution: Carburetor adjustment should only be performed by a qualified technician. Incorrect adjustments can damage the engine. I always take my saw to a certified Stihl dealer for carburetor adjustments.
Bar and Chain Maintenance: Extending Lifespan
- Bar Cleaning: Regularly clean the bar groove to remove sawdust and debris. This ensures proper chain lubrication.
- Bar Dressing: Use a bar dresser to remove burrs and restore the bar’s shape.
- Chain Lubrication: Use a high-quality bar and chain oil to reduce friction and wear. Check the oil level frequently and refill as needed.
Data Point: Proper chain lubrication can extend the life of the bar and chain by up to 50%.
Safety Equipment Requirements: Protecting Yourself
Operating a chainsaw is inherently dangerous. Wearing the proper safety equipment is essential for minimizing the risk of injury.
Personal Protective Equipment (PPE)
- Chainsaw Chaps: These provide crucial protection for your legs, which are particularly vulnerable to chainsaw injuries.
