Mastering the Stihl 201T: Safety Tips and Pro Arborist Tricks

The Stihl 201T chainsaw is a lightweight, powerful tool favored by arborists worldwide for its maneuverability and performance in tree care. However, its top-handle design and intended use in aerial environments demand a high degree of skill and a relentless focus on safety. Over the years, I’ve seen firsthand the consequences of complacency and improper technique. From minor cuts to serious injuries, the risks are real, and they’re amplified when working at height.

This guide isn’t just a rehash of the owner’s manual. I’m going to share insights I’ve gleaned from years of climbing, cutting, and collaborating with some of the best arborists in the business. These are the “tricks of the trade” – the nuances that separate safe, efficient work from a potential disaster. We’ll dive into the specific safety considerations for the 201T, focusing on techniques used by professional arborists.

Understanding the Stihl 201T: A Technical Overview

Before we delve into the safety tips, let’s establish a solid understanding of the tool itself. The Stihl 201T is a gasoline-powered chainsaw designed for pruning and light tree felling. Its key features include:

• Engine Displacement: Typically around 35.2 cc.
• Power Output: Approximately 1.8 kW (2.4 bhp).
• Weight: Around 3.7 kg (8.2 lbs) without fuel, bar, and chain. This is a critical factor for aerial work.
• Guide Bar Length: Commonly available in lengths from 12″ to 16″.
• Chain Type: Typically a low-kickback chain, but understanding the chain’s specifications is crucial.
• Fuel Tank Capacity: Around 0.33 liters.
• Oil Tank Capacity: Around 0.22 liters.

Technical Specifications & Requirements:

1. Fuel Mixture: Always use a 50:1 ratio of gasoline to two-stroke oil, specifically designed for air-cooled engines. Using incorrect mixtures can lead to engine damage and increased emissions. Stihl recommends their own brand of oil, but high-quality alternatives are acceptable, provided they meet the JASO FD or ISO-L-EGD standards.
2. Chain Tension: Proper chain tension is crucial for safety and performance. The chain should be snug against the guide bar but still able to be pulled around by hand. A chain that is too loose can derail, while a chain that is too tight can overheat and break. I check the tension every time I refuel.
3. Carburetor Adjustment: The carburetor controls the air-fuel mixture. Improper adjustment can lead to poor performance, increased emissions, and potential engine damage. If you notice issues like stalling, difficulty starting, or excessive smoke, consult a qualified technician for adjustment.
4. Spark Plug: Use the specified spark plug (e.g., NGK BPMR7A) and replace it regularly (typically every 100 hours of operation). A worn or fouled spark plug can cause starting problems and reduced engine performance.
5. Air Filter: Clean the air filter regularly (daily in dusty conditions). A clogged air filter restricts airflow, leading to reduced power and increased fuel consumption.

Pro Arborist Trick #1: The “One-Handed Start” Myth and the Reality of Secure Starts

One of the most dangerous things I see is arborists attempting one-handed starts while in the tree. The 201T, with its top handle, can seem like it’s designed for one-handed operation, but starting it that way is a recipe for disaster.

The Problem: One-handed starts leave you vulnerable. If the chain catches, you have no control, and the saw can swing wildly, potentially causing injury or loss of balance.

The Arborist Solution:

1. Ground Starts: Whenever possible, start the saw on the ground, using your foot to secure it. Ensure the chain brake is engaged.
2. In-Tree Starts (Emergency Only): If you absolutely must start the saw in the tree, use a lanyard or rope to secure the saw to a sturdy branch. This prevents it from falling if you lose control. Then, brace the saw against your leg or body, using both hands to start it.
3. Check the Chain Brake: Before every start, always ensure the chain brake is engaged. This is your first line of defense against accidental chain movement.
4. Drop Starting is a NO-GO: Never drop-start a chainsaw. This technique is extremely dangerous and provides no control over the saw.

Data Point: A study by the Tree Care Industry Association (TCIA) found that approximately 15% of chainsaw-related injuries among arborists are caused by improper starting techniques.

Pro Arborist Trick #2: The “Master Grip” and Body Positioning for Control

The way you hold the saw and position your body has a massive impact on control and safety. The 201T is designed for maneuverability, but that also means it’s more susceptible to kickback if not handled correctly.

The Problem: A weak grip or poor body positioning can lead to loss of control, especially when cutting at awkward angles or in confined spaces.

The Arborist Solution:

1. The Master Grip: Use a firm, two-handed grip whenever possible. Wrap your fingers tightly around the handles, and keep your wrists straight. This provides maximum control and reduces fatigue.
2. Body Positioning: Position yourself so that you are balanced and stable. Avoid reaching or overextending yourself. Move your feet to adjust your position rather than reaching with the saw.
3. Kickback Zone Awareness: Be acutely aware of the “kickback zone” – the upper quadrant of the guide bar. Avoid cutting with this part of the bar, as it’s the most likely to cause kickback.
4. Cutting Stance: Maintain a wide, stable stance with your weight evenly distributed. This will help you absorb any unexpected movements of the saw.
5. Use a Lanyard Wisely: When aloft, employ a secondary lanyard to secure the saw to your harness. This reduces strain and prevents the saw from swinging uncontrollably if you need to adjust your grip.
6. Thumb Placement: Ensure your thumb is wrapped securely around the handle, not just resting on it. This provides a stronger grip and better control.

Data Point: According to the Occupational Safety and Health Administration (OSHA), kickback is a leading cause of chainsaw-related injuries. Proper grip and body positioning can significantly reduce the risk of kickback.

Pro Arborist Trick #3: The “Kerf Awareness” and Preventing Pinching

Pinching occurs when the wood closes in on the saw blade during a cut, trapping the saw and potentially causing kickback. This is a common problem, especially when cutting limbs under tension.

The Problem: Pinching can damage the saw, lead to kickback, and create a dangerous situation for the operator.

The Arborist Solution:

1. Assess the Tension: Before making any cut, carefully assess the tension in the limb. Look for signs of bending or compression.
2. Relief Cuts: Make relief cuts on the compression side of the limb before making the final cut. This will relieve the tension and prevent pinching.
3. Wedges and Levers: Use wedges or levers to keep the kerf open and prevent the wood from closing in on the saw.
4. Cutting Techniques: Employ techniques like bore cutting (plunging the saw into the wood) to create a space for the saw blade to move freely.
5. Felling Wedges: When felling trees, use felling wedges to control the direction of the fall and prevent the tree from pinching the saw.
6. Chain Sharpness: A sharp chain reduces the likelihood of pinching. A dull chain requires more force to cut, increasing the risk of the wood closing in on the blade.

Data Point: A study published in the Journal of Arboriculture found that using proper cutting techniques and relief cuts can reduce the incidence of pinching by up to 75%.

Pro Arborist Trick #4: The “Pre-Climb Saw Check” and Identifying Potential Hazards

Before you even start the saw, a thorough inspection is critical. I call it the “Pre-Climb Saw Check,” but it applies to any situation where you’re using the 201T. It goes beyond a simple visual inspection.

The Problem: Overlooking potential hazards can lead to equipment failure, accidents, and injuries.

The Arborist Solution:

1. Chain Sharpness: Check the chain for sharpness, damage, and proper tension. A dull or damaged chain is a safety hazard.
2. Chain Brake: Ensure the chain brake is functioning correctly. Test it before each use.
3. Throttle Trigger and Interlock: Check that the throttle trigger and interlock are operating smoothly. The interlock prevents accidental throttle activation.
4. Fuel and Oil Levels: Check the fuel and oil levels. Running the saw with low fuel or oil can damage the engine.
5. Air Filter: Inspect the air filter for dirt and debris. A clogged air filter can reduce engine performance.
6. Guide Bar: Check the guide bar for wear and damage. A worn or damaged guide bar can cause chain derailment.
7. Anti-Vibration System: Ensure the anti-vibration system is functioning correctly. This system reduces fatigue and improves control.
8. Visual Inspection: Look for any signs of damage, such as cracks, leaks, or loose parts.
9. Personal Protective Equipment (PPE): Ensure you have all the necessary PPE, including a helmet, eye protection, hearing protection, gloves, and chainsaw-resistant chaps or pants.
10. First Aid Kit: Ensure your first aid kit is well stocked and easily accessible.
11. Communication: Establish clear communication protocols with ground crew before starting any work.

Data Point: According to the International Society of Arboriculture (ISA), regular equipment inspections can reduce the risk of chainsaw-related accidents by up to 30%.

Pro Arborist Trick #5: The “Situational Awareness” and Predicting Limb Movement

Arborists don’t just cut wood; they manage the forces of gravity and tension. Predicting how a limb will react when cut is crucial for safety. This is what I call “Situational Awareness” – constantly assessing the environment and anticipating potential hazards.

The Problem: Unpredictable limb movement can lead to accidents, injuries, and damage to property.

The Arborist Solution:

1. Assess the Weight and Balance: Before making any cut, carefully assess the weight and balance of the limb.
2. Consider the Wind: The wind can significantly affect limb movement. Be aware of the wind direction and speed.
3. Look for Obstacles: Identify any obstacles that the limb could hit when it falls, such as power lines, buildings, or people.
4. Plan the Fall Path: Plan the fall path of the limb and ensure that it is clear of obstacles.
5. Use Ropes and Rigging: Use ropes and rigging to control the fall of the limb and prevent it from swinging uncontrollably.
6. Communicate with the Ground Crew: Maintain clear communication with the ground crew to ensure that they are aware of the plan and any potential hazards.
7. Escape Route: Always have a clear escape route planned in case of unexpected limb movement.
8. Don’t Rush: Take your time and carefully assess the situation before making any cuts. Rushing can lead to mistakes and accidents.

Data Point: A study by the National Arborist Foundation found that approximately 40% of tree-related accidents are caused by misjudging limb movement.

Wood Selection Criteria: Matching Material to the Task

Understanding wood properties is fundamental to safe and efficient wood processing. The type of wood you’re cutting directly impacts the chainsaw’s performance and the potential for hazards. Hardwoods, for example, require more power and can generate more heat, increasing the risk of chain binding and kickback. Softwoods, on the other hand, tend to splinter more easily, which can create flying debris.

Hardwoods vs. Softwoods: Key Differences

Technical Requirements for Wood Selection:

1. Moisture Content: For firewood, aim for a moisture content of 20% or less. Use a moisture meter to accurately measure the moisture content. Higher moisture content reduces burning efficiency and increases the risk of creosote buildup in chimneys.
2. Log Diameter: The Stihl 201T is best suited for logs with a diameter of 12 inches or less. Attempting to cut larger logs can overload the saw and increase the risk of kickback.
3. Wood Species: Choose wood species that are appropriate for the intended use. For example, hardwoods like oak and maple are excellent for firewood due to their high heat output and long burn time. Softwoods like pine and fir are better suited for construction due to their ease of cutting and straight grain.
4. Defect Assessment: Inspect logs for defects such as knots, cracks, and rot. These defects can weaken the wood and make it more prone to splitting or breaking during cutting. Avoid cutting logs with significant defects.

Practical Tips for Wood Selection:

• Seasoning Firewood: Allow firewood to season (dry) for at least six months before burning. This reduces the moisture content and improves burning efficiency. Stack the wood in a well-ventilated area and cover it to protect it from rain and snow.
• Identifying Wood Species: Learn to identify different wood species by their bark, leaves, and grain. This will help you choose the right wood for the intended use.
• Sourcing Wood: Source wood from reputable suppliers who can provide information about the wood’s species, moisture content, and origin. Avoid using wood that has been treated with chemicals, as these chemicals can release harmful fumes when burned.

Tool Calibration Standards: Maintaining Peak Performance

A well-maintained chainsaw is a safe chainsaw. Regular calibration and maintenance are essential for ensuring peak performance and preventing accidents. This includes checking and adjusting the carburetor, sharpening the chain, and lubricating the guide bar.

Carburetor Adjustment:

The carburetor controls the air-fuel mixture, and improper adjustment can lead to poor performance, increased emissions, and potential engine damage. The Stihl 201T typically has three adjustment screws:

• L (Low-Speed): Adjusts the fuel mixture at idle speed.
• H (High-Speed): Adjusts the fuel mixture at high speed.
• LA (Idle Speed): Adjusts the engine speed at idle.

Calibration Standards:

1. Idle Speed: Adjust the idle speed so that the chain does not move when the saw is idling. Refer to the owner’s manual for the recommended idle speed.
2. Low-Speed Adjustment: Adjust the low-speed screw until the engine idles smoothly and responds quickly to throttle input.
3. High-Speed Adjustment: Adjust the high-speed screw until the engine runs smoothly at full throttle. Avoid running the engine too lean (too much air, not enough fuel), as this can damage the engine.
4. Professional Calibration: If you are not comfortable adjusting the carburetor yourself, take the saw to a qualified technician for calibration.

Chain Sharpening Standards:

A sharp chain is essential for safe and efficient cutting. A dull chain requires more force to cut, increasing the risk of kickback and pinching.

1. File Size: Use the correct file size for the chain type. Refer to the owner’s manual for the recommended file size.
2. Filing Angle: Maintain the correct filing angle. The filing angle is typically marked on the chain.
3. Depth Gauge: Check the depth gauge (raker) height. If the depth gauge is too high, the chain will not cut effectively. If the depth gauge is too low, the chain will be more prone to kickback.
4. Consistent Sharpening: Sharpen each tooth consistently to ensure that they are all the same height and shape.
5. Professional Sharpening: If you are not comfortable sharpening the chain yourself, take it to a qualified technician for sharpening.

Guide Bar Maintenance Standards:

The guide bar supports the chain and helps to guide it through the wood. Regular maintenance is essential for ensuring that the guide bar is in good condition.

1. Cleaning: Clean the guide bar regularly to remove dirt and debris.
2. Lubrication: Lubricate the guide bar regularly with chainsaw bar oil.
3. Burr Removal: Remove any burrs from the edges of the guide bar with a flat file.
4. Groove Cleaning: Clean the groove in the guide bar with a guide bar cleaner.
5. Wear Inspection: Check the guide bar for wear and damage. Replace the guide bar if it is worn or damaged.

Practical Tips for Tool Calibration:

• Use a Tachometer: Use a tachometer to accurately measure the engine speed when adjusting the carburetor.
• Follow the Owner’s Manual: Refer to the owner’s manual for specific instructions on calibrating and maintaining the chainsaw.
• Keep a Maintenance Log: Keep a log of all maintenance activities, including the date, type of maintenance performed, and any parts replaced.

Safety Equipment Requirements: Protecting Yourself from Hazards

Personal protective equipment (PPE) is essential for protecting yourself from the hazards of chainsaw operation. This includes a helmet, eye protection, hearing protection, gloves, and chainsaw-resistant chaps or pants.

Minimum PPE Requirements:

1. Helmet: A helmet protects your head from falling objects and impacts. Choose a helmet that meets ANSI Z89.1 standards.
