Stihl MS 361 Specs and 5 Pro Tips for Arborists

I’ve always believed that understanding your tools is the first step towards mastering any craft. The Stihl MS 361 is a chainsaw that has earned its reputation through dependability and performance. Let’s delve into the technical aspects of this iconic saw before exploring how to maximize its potential in your arborist work.

Stihl MS 361: A Deep Dive into the Specs

The MS 361, while no longer in production, remains a staple in many professional’s arsenals, and for a good reason. Here’s a breakdown of its key specifications:

• Engine Displacement: 59 cc (3.6 cu. in.)
• Power Output: 3.4 kW (4.6 bhp)
• Weight (Powerhead Only): 5.6 kg (12.3 lbs) – a great balance of power and portability
• Power-to-Weight Ratio: 1.6 kg/kW
• Fuel Tank Capacity: 680 cc (23 fl. oz.)
• Oil Tank Capacity: 330 cc (11 fl. oz.)
• Recommended Bar Lengths: 16″ to 25″ – versatility for various tasks
• Chain Pitch: .325″ or 3/8″ – depending on the configuration

These specs translate to a saw that’s powerful enough for felling medium-sized trees, limbing larger ones, and bucking logs into manageable lengths. The relatively light weight makes it easier to handle for extended periods, reducing fatigue. The fuel and oil capacities are generous enough to minimize downtime for refills during a typical workday.

Why These Specs Matter:

Understanding these specs isn’t just about memorizing numbers. It’s about understanding the saw’s capabilities and limitations. For example, knowing the power output helps you choose the right bar length for the job. Using too long a bar on a less powerful saw will bog it down and reduce cutting efficiency. Knowing the weight helps you plan for the physical demands of the job and choose appropriate safety gear.

Pro Tip #1: Master the Art of Chainsaw Maintenance

I can’t stress enough the importance of regular chainsaw maintenance. A well-maintained saw is not only safer to use, but it also performs better, lasts longer, and saves you money in the long run.

My Personal Experience:

I once worked with a crew that neglected their chainsaw maintenance. They were constantly dealing with dull chains, clogged air filters, and malfunctioning carburetors. Their productivity was significantly lower than mine, and they ended up spending a fortune on repairs and replacements. That experience cemented my belief in the value of proactive maintenance.

Actionable Steps:

• Sharpen Your Chain Regularly: A sharp chain cuts faster, smoother, and with less effort. I sharpen my chain every time I refuel, using a file and guide to maintain the correct angles.
  • Data Point: A sharp chain can increase cutting speed by up to 30%, according to Oregon Products, a leading manufacturer of chainsaw chains.
• Clean the Air Filter: A clogged air filter restricts airflow, reducing engine power and increasing fuel consumption. Clean the air filter after every use, using compressed air or a brush.
• Check the Spark Plug: A fouled spark plug can cause starting problems and poor engine performance. Inspect the spark plug regularly and replace it as needed.
• Lubricate the Bar and Chain: Proper lubrication reduces friction, extending the life of the bar and chain. Use a high-quality bar and chain oil, and adjust the oiler to ensure adequate lubrication.
  • My Trick: I slightly over-oil my chain when cutting hardwoods to prevent overheating.
• Inspect the Saw Regularly: Look for loose screws, worn parts, and any signs of damage. Address any issues promptly to prevent them from escalating.
• Store Your Saw Properly: Store your saw in a dry, clean place, away from direct sunlight and extreme temperatures. Drain the fuel tank before storing the saw for extended periods.
• Chain Tension: Ensure your chain tension is just right. Too tight, and you’ll wear out the bar and chain prematurely. Too loose, and it’ll derail.

Cost Savings:

Regular maintenance can significantly reduce your repair costs. For example, replacing a worn-out chain can cost anywhere from $30 to $100, while sharpening a chain costs only a few dollars. Similarly, replacing a damaged bar can cost hundreds of dollars, while proper lubrication can extend its life by years.

Pro Tip #2: Master Felling Techniques

Felling trees is one of the most dangerous aspects of arboriculture. It requires careful planning, precise execution, and a thorough understanding of tree behavior.

A Close Call:

I once witnessed a near-fatal accident when a tree fell in an unexpected direction, narrowly missing a colleague. That incident served as a stark reminder of the importance of safety and proper felling techniques.

Actionable Steps:

• Assess the Tree: Before felling a tree, carefully assess its size, shape, lean, and any signs of decay or damage. Look for overhead hazards, such as dead limbs or power lines.
• Plan Your Escape Route: Identify a clear escape route that is at least 45 degrees away from the direction of fall. Clear the area of any obstacles.
• Make a Notch Cut: The notch cut determines the direction of fall. It should be at least one-third the diameter of the tree.
• Make a Back Cut: The back cut should be slightly above the notch cut, leaving a hinge of wood to control the fall.
• Use Wedges: If the tree is leaning in the wrong direction, use wedges to help guide its fall.
• Communicate with Your Team: Clearly communicate your intentions to your team members and ensure that everyone is aware of the potential hazards.
• Never Work Alone: Always work with a partner or team when felling trees.

Key Considerations:

• Tree Lean: Trees naturally lean in a certain direction. Factor this into your felling plan.
• Wind: Wind can significantly affect the direction of fall. Avoid felling trees in high winds.
• Terrain: Uneven terrain can make felling more difficult. Choose a safe and stable footing.
• Tree Species: Different tree species have different wood densities and felling characteristics.

Expert Quote:

“Felling trees is not a race; it’s a calculated dance. Take your time, assess the situation, and execute with precision.” – Sven Karlsson, Master Arborist

Pro Tip #3: Optimize Your Limbing and Bucking Techniques

Limbing and bucking are essential steps in wood processing. Efficient techniques can save you time and effort while minimizing waste.

My Time-Saving Strategy:

I developed a limbing and bucking strategy that involves a combination of strategic cuts and efficient movement. This has significantly increased my productivity.

Actionable Steps:

• Limbing:
  • Start from the Base: Begin limbing from the base of the tree and work your way up.
  • Use a Lever: Use the tree trunk as a lever to support the limbs while cutting.
  • Avoid Pinching: Be careful not to pinch the saw bar when limbing.
  • Cut Flush: Cut the limbs flush with the trunk to prevent rot and decay.
• Bucking:
  • Measure Accurately: Measure the logs accurately to ensure consistent lengths.
  • Support the Log: Support the log to prevent it from pinching the saw bar.
  • Use a Bucking Saw: A bucking saw can make bucking faster and easier.
  • Cut at an Angle: Cut the logs at a slight angle to prevent them from rolling.
• Stihl MS 361 Specifics: The MS 361’s power and weight make it an excellent choice for both limbing and bucking. Its maneuverability allows for precise cuts, while its power handles larger logs with ease.
