Stihl MS 200T Chainsaw Guide: 5 Pro Tips for Arborists

The Stihl MS 200T is a legend in the arborist world. Lightweight, powerful, and designed specifically for in-tree work, it’s the go-to saw for countless professionals. But even the best tools require understanding and finesse. This guide will go beyond the basics, sharing my personal insights and pro tips to help you get the most out of your MS 200T.

1. Mastering Precision Cuts: The Art of the Arborist’s Touch

The MS 200T isn’t just about brute force; it’s about precision. In the canopy, every cut matters. A poorly executed cut can damage the tree, create hazards, or even compromise your safety.

Understanding the Importance of Hinge Wood

Hinge wood is the uncut portion of the branch that controls the direction of the fall. It’s the arborist’s steering wheel. The size and placement of the hinge are critical for safe and controlled removals.

Too Thin: A thin hinge can break prematurely, leading to unpredictable branch fall.
Too Thick: A thick hinge can cause the branch to barber chair (split upwards) as it falls, posing a serious hazard.
Incorrect Placement: Improper placement can cause the branch to swing unexpectedly.

My Experience: I once witnessed a near-miss when an arborist misjudged the hinge wood on a large limb. The branch swung wildly, narrowly missing a ground worker. That incident reinforced the importance of meticulous cut planning.

The Three-Cut Technique (Modified for Aerial Work)

This technique is a staple for controlled branch removals. Here’s how I adapt it for the MS 200T in aerial settings:

Undercut: Make an undercut about one-third of the branch diameter. This prevents the bark from tearing as the branch falls.
Top Cut: Make a top cut slightly further out than the undercut, aiming to meet it precisely.
Hinge Cut: This is the most critical cut. Carefully sever the remaining wood, leaving the desired hinge. I often use a plunging cut for enhanced control.

Pro Tip: When making the hinge cut, pay close attention to the wood fibers. They’ll tell you how the branch is reacting to the cut.

Plunge Cutting: Your Secret Weapon for Precision

The MS 200T’s compact size makes it ideal for plunge cutting. This technique allows you to make precise cuts in tight spaces, minimizing damage to the tree.

How to Plunge Cut: With the saw running, carefully tip the bar into the wood, using the bottom of the bar to guide the cut. Keep the saw moving smoothly and avoid forcing it.
Applications: Plunge cutting is perfect for creating notches, removing small branches, and making precise hinge cuts.

Data Point: In a study conducted by the International Society of Arboriculture (ISA), arborists who used plunge cutting techniques reported a 15% reduction in tree damage compared to those who relied solely on traditional cutting methods.

Avoiding Pinching: A Common Pitfall

Pinching occurs when the weight of the branch closes the cut, trapping the saw bar. This can be frustrating and dangerous.

Prevention: Use wedges to keep the cut open, especially when cutting larger branches.
Recovery: If the saw gets pinched, don’t force it. Use a wedge or a second saw to relieve the pressure.

Expert Insight: “Pinching is a sign that you’re not reading the tree,” says veteran arborist, Mark Johnson. “Pay attention to the weight distribution and use wedges proactively.”

2. Optimizing Maintenance: Keeping Your MS 200T in Peak Condition

A well-maintained MS 200T is a reliable and efficient tool. Neglecting maintenance, on the other hand, can lead to costly repairs and downtime.

Daily Maintenance: The Foundation of Longevity

These tasks should be performed every day before and after use:

Air Filter: Clean the air filter. A clogged filter restricts airflow, reducing power and increasing fuel consumption. I use compressed air to blow out debris.
Chain: Sharpen the chain. A sharp chain cuts faster, smoother, and safer.
Bar: Clean the bar groove and oil holes. A clean bar ensures proper lubrication.
Fuel and Oil: Check fuel and oil levels. Always use high-quality two-stroke oil mixed at the correct ratio.
Visual Inspection: Inspect the saw for any loose bolts, damaged parts, or leaks.

My Routine: Before each climb, I run through this checklist meticulously. It’s a ritual that gives me confidence in my equipment.

Weekly Maintenance: Deeper Dive for Optimal Performance

These tasks should be performed monthly:

Carburetor Adjustment: Check and adjust the carburetor if necessary. Improper carburetor settings can lead to poor performance and engine damage. Note: Carburetor adjustments should be done by a qualified technician if you are not comfortable with the process.
Bar Rails: Dress the bar rails. Uneven rails can cause the chain to bind.
Chain Sprocket: Inspect the chain sprocket for wear. A worn sprocket can damage the chain.

Pro Tip: Keep a detailed maintenance log. This will help you track your maintenance schedule and identify potential problems early on.

The Importance of Proper Chain Sharpening

A dull chain is not only inefficient, but also dangerous. It requires more force to cut, increasing the risk of kickback.

Sharpening Tools: Use a quality file and guide to maintain the correct cutting angles.
Sharpening Technique: Follow the manufacturer’s instructions for sharpening your specific chain type.
Frequency: Sharpen the chain whenever it becomes dull. I often sharpen my chain multiple times a day.
