Stihl MS390 Price Guide: 5 Expert Tips for Used Chainsaws

Finding a used Stihl MS390 chainsaw can be a smart move for budget-conscious individuals or those needing a dependable backup saw. However, buying used requires careful evaluation to ensure you’re getting a good deal and a functional tool. I’ll walk you through the key aspects to consider, from assessing the saw’s condition to understanding fair pricing.

Understanding the Stihl MS390 Chainsaw

Before diving into the used market, let’s understand what makes the Stihl MS390 a popular choice. It’s a mid-range chainsaw known for its power, reliability, and ease of use.

Engine: Typically features a 64.1 cc engine, providing ample power for felling small to medium-sized trees and processing firewood.
Bar Length: Commonly used with a 16-inch to 20-inch bar, offering versatility for various cutting tasks.
Weight: Weighs around 13.9 lbs (without fuel and bar), making it manageable for extended use.
Features: Often includes features like Stihl’s Quick Chain Adjuster (on some models), side-access chain tensioner, and anti-vibration system.

Factors Influencing the Price of a Used Stihl MS390

The price of a used Stihl MS390 chainsaw can vary significantly based on several factors. Understanding these factors will help you determine a fair price and avoid overpaying.

Condition: The most crucial factor. A saw in excellent condition will command a higher price than one with significant wear and tear.
Age: Older saws generally depreciate in value. However, a well-maintained older saw can still be a good investment.
Usage: A saw used commercially will likely have more wear and tear than one used for occasional homeowner tasks.
Location: Prices can vary depending on your geographic location and the local market demand.
Included Accessories: If the saw comes with extra chains, a carrying case, or other accessories, it can increase its value.

Expert Tip 1: Assessing the Chainsaw’s Condition

Thoroughly inspecting the chainsaw’s condition is paramount. Don’t rely solely on appearances; dig deeper to uncover potential problems.

Visual Inspection:
- Exterior: Look for cracks, damage, or excessive wear on the housing, handle, and other components.
- Bar and Chain: Check the bar for straightness, wear, and damage. Examine the chain for sharpness, damage, and proper tension.
- Spark Plug: Remove the spark plug and inspect its condition. A fouled or damaged spark plug can indicate engine problems.
- Air Filter: Check the air filter for cleanliness and damage. A dirty air filter can restrict airflow and affect engine performance.
Mechanical Inspection:
- Compression Test: This is critical. Low compression indicates engine wear. You can use a compression tester or ask the seller if they’ve had it tested. A healthy MS390 should have a compression reading above 120 PSI.
- Starting: Observe how easily the saw starts. A saw that requires excessive pulling or refuses to start may have engine issues.
- Idling: Once started, the saw should idle smoothly without stalling. Erratic idling can indicate carburetor problems.
- Acceleration: Test the saw’s acceleration. It should respond quickly and smoothly to throttle input. Hesitation or stalling during acceleration can indicate fuel system problems.
- Chain Oiler: Ensure the chain oiler is functioning correctly. The chain should be lubricated while running. Insufficient lubrication can damage the bar and chain.
Hidden Problems to Watch Out For:
- Cracked Crankcase: Difficult to detect but can lead to major engine failure.
- Worn Piston Rings: Can cause low compression and reduced power.
- Fuel Leaks: Check for fuel leaks around the carburetor, fuel lines, and fuel tank.
- Excessive Vibration: Can indicate worn engine mounts or other mechanical problems.

Personal Story: I once purchased a used chainsaw that looked great on the outside. However, after a few hours of use, I discovered a crack in the crankcase. The repair cost ended up exceeding the price I paid for the saw. This experience taught me the importance of a thorough inspection.

Takeaway: A meticulous inspection is your best defense against buying a lemon. Don’t hesitate to ask the seller questions and request a demonstration.

Expert Tip 2: Determining a Fair Price

Establishing a fair price for a used Stihl MS390 involves considering its condition, age, and market value. Here’s how to approach it:

Research Market Value:
- Online Marketplaces: Check eBay, Craigslist, Facebook Marketplace, and other online platforms for similar models. Pay attention to the asking prices and the final selling prices (if available).
- Local Dealers: Contact local Stihl dealers or repair shops. They may have used saws for sale or be able to provide an estimate of the saw’s value.
- Price Guides: While dedicated price guides for used chainsaws are rare, you can use online resources and forums to gather pricing information.
Factor in Condition:
- Excellent Condition: A saw in excellent condition, with minimal wear and tear, can command a premium price. Expect to pay closer to the original MSRP (Manufacturer Suggested Retail Price), adjusted for age.
- Good Condition: A saw in good condition, with some signs of wear but no major mechanical issues, should be priced lower than a saw in excellent condition.
- Fair Condition: A saw in fair condition, with noticeable wear and tear and potentially some minor mechanical issues, should be priced significantly lower.
- Poor Condition: A saw in poor condition, with significant wear and tear and potentially major mechanical issues, should be priced very low or avoided altogether unless you’re comfortable with repairs.
Negotiation:
- Be Prepared to Negotiate: Don’t be afraid to negotiate the price. Point out any flaws or issues you’ve identified during your inspection.
- Know Your Limit: Set a maximum price you’re willing to pay and stick to it. Don’t get caught up in the excitement of the negotiation and overpay.
- Walk Away if Necessary: If the seller is unwilling to negotiate or if you’re not comfortable with the price, be prepared to walk away. There are other saws out there.

Data Point: Based on my research of online marketplaces, a used Stihl MS390 in good condition typically sells for between $250 and $400. However, this range can vary depending on the factors mentioned above.

Takeaway: Thorough research and a willingness to negotiate are essential for securing a fair price on a used Stihl MS390.

Expert Tip 3: Checking for Common Problems

Certain problems are more common in used chainsaws. Knowing what to look for can help you avoid costly repairs down the road.

Carburetor Issues:
- Symptoms: Difficult starting, erratic idling, stalling, poor acceleration.
- Causes: Dirty carburetor, clogged fuel lines, damaged fuel filter.
- Inspection: Check the fuel lines for cracks or leaks. Inspect the fuel filter for debris. Listen for unusual noises from the carburetor.
Ignition Problems:
- Symptoms: Difficult starting, no spark, intermittent running.
- Causes: Faulty spark plug, damaged ignition coil, broken wiring.
- Inspection: Check the spark plug for fouling or damage. Test the spark by removing the spark plug, grounding it against the engine, and pulling the starter cord. You should see a strong spark.
Compression Issues:
- Symptoms: Difficult starting, low power, poor performance.
- Causes: Worn piston rings, damaged cylinder, leaking valves (on some models).
- Inspection: Perform a compression test. A healthy MS390 should have a compression reading above 120 PSI.
Chain Oiler Problems:
- Symptoms: Dry chain, excessive wear on the bar and chain, overheating.
- Causes: Clogged oil lines, faulty oil pump, blocked oil filter.
- Inspection: Check the oil tank for adequate oil level. Inspect the oil lines for leaks or blockages. Observe the chain while running to ensure it’s being lubricated.

Case Study: A friend of mine bought a used Stihl MS390 with a “minor” carburetor issue. After spending hours trying to clean and rebuild the carburetor, he discovered that the carburetor body was cracked. He ended up replacing the entire carburetor, which added significantly to the cost of the saw.

Takeaway: Be vigilant in checking for common problems. A seemingly minor issue can often be a sign of a more significant underlying problem.

Expert Tip 4: Asking the Right Questions

Don’t hesitate to ask the seller questions about the chainsaw’s history and usage. Their answers can provide valuable insights into its condition and potential problems.

Usage History:
- How often was the saw used?
- What types of cutting tasks was it used for?
- Was it used commercially or for personal use?
Maintenance History:
- When was the last time the saw was serviced?
- What type of fuel and oil was used?
- Was the chain sharpened regularly?
Repair History:
- Has the saw ever been repaired?
- If so, what repairs were performed?
- Who performed the repairs?
Reason for Selling:
- Why are you selling the saw?
- Are you upgrading to a newer model?
- Are you no longer using the saw?

Important Note: Pay attention to the seller’s demeanor and honesty. If they seem evasive or unwilling to answer your questions, it may be a red flag.

Takeaway: Asking the right questions can help you uncover hidden problems and make a more informed decision.

Expert Tip 5: Safety Considerations

Safety should always be your top priority when purchasing and using a chainsaw.

Personal Protective Equipment (PPE):
- Always wear appropriate PPE when operating a chainsaw, including:
  - Safety glasses or a face shield
  - Hearing protection
  - Gloves
  - Chainsaw chaps or pants
  - Steel-toed boots
Chainsaw Safety Features:
- Ensure the chainsaw has functional safety features, including:
  - Chain brake
  - Throttle lock
  - Chain catcher
Safe Operating Practices:
- Read and understand the chainsaw’s owner’s manual.
- Maintain a firm grip on the saw with both hands.
- Keep your feet firmly planted and maintain a stable stance.
- Be aware of your surroundings and avoid cutting in hazardous conditions.
- Never operate a chainsaw when you’re tired, distracted, or under the influence of drugs or alcohol.

Real-World Example: I once witnessed a logger who wasn’t wearing safety glasses get hit in the eye by a piece of wood chip. He suffered a serious eye injury that required medical attention. This incident reinforced the importance of wearing PPE at all times.

Takeaway: Prioritizing safety is crucial when working with chainsaws. Always wear appropriate PPE and follow safe operating practices.
