Understanding Your Chainsaw’s Controls

Understanding the STIHL Master Control Lever and Initial Preparations

Before you initiate the start-up process, familiarize yourself with the Master Control lever’s symbols and positions:

Cold Start Position: How to Prepare Your Chainsaw for First-Time Use

Essential when beginning the operation of your STIHL chainsaw from a completely inactive state. It’s particularly pertinent when the engine is cold, which typically means it hasn’t been run recently or has cooled down after previous use. This position is also crucial if your chainsaw’s engine has stopped due to running out of fuel, as it primes the engine for a fresh start. When selected, this position adjusts the chainsaw’s internal mechanisms, such as the choke, enriching the fuel mixture delivered to the engine. This enriched mixture is necessary to initiate the combustion process in a cold engine, ensuring a smoother start.

Warm Start Position: How to Restart a Warm Chainsaw

Designed for situations where the chainsaw’s engine is not entirely cold but might need some assistance to get going again. This could be shortly after the engine has been in operation and is still warm, or when you notice the engine is trying to start (often recognizable by specific sounds or partial engagement). This position fine-tunes the fuel mixture and air intake to suit an engine that’s not as cold and doesn’t require the full assistance of the cold start setting. It’s a midway point that helps in restarting the engine without over-flooding it with fuel, ensuring a balance for optimal restart performance.

Run Position: Maintaining Optimal Chainsaw Performance

Where you’ll have the lever most of the time during the operation of your STIHL chainsaw. Once the chainsaw has been started successfully, shifting to this position allows you to operate the chainsaw under normal conditions. Whether you’re cutting, trimming, or performing any other task, this position ensures that the chainsaw delivers consistent and stable performance. It maintains a standard fuel-to-air ratio, suitable for the engine to run efficiently while you’re working. It’s the go-to setting for regular chainsaw operation, ensuring the engine runs smoothly and responds correctly to your input.

Off Position: Safely Turning Off Your Chainsaw

The safety anchor of your chainsaw’s operations. When you’re done with your tasks, or if you need to safely stop the chainsaw for any reason, shifting the Master Control Lever to this position will shut down the engine. It effectively disables the chainsaw’s ignition system, ensuring that the engine stops running and the chainsaw ceases operation. This position is crucial for safe handling, transport, or storage of your chainsaw, preventing accidental starts or undesired operation. It’s a fundamental safety feature that provides peace of mind, ensuring that the chainsaw remains inactive when not in use.

Note that the exact location of the STIHL Master Control lever and its symbols may vary slightly by model. If your chainsaw looks different from the standard, refer to your product-specific instruction manual for detailed guidance.

Essential Pre-Start Safety Checks for Your STIHL Chainsaw

Before you initiate the start-up of your STIHL chainsaw, conducting a series of safety checks is imperative. These checks are designed to ensure not just the smooth operation of your chainsaw but also your safety and the safety of those around you. Here are the key pre-start safety checks you should always perform:

Step 1: Inspect Fuel and Oil Caps

The first step is to check the fuel and oil caps on your chainsaw. Ensure that these caps are tightened securely. A loose cap can lead to fuel or oil leakage, which not only wastes these fluids but can also pose serious safety hazards. After securing the caps, inspect the chainsaw for any spilled fuel or oil. If you find any, clean it up thoroughly. This prevents the risk of fire and ensures that your working environment is safe.

Step 2: Examine Your Chainsaw for Damage or Wear

A thorough examination of the chainsaw is crucial before starting it. Check every part of the chainsaw to make sure everything is intact. Pay close attention to ensure that no parts are broken, missing, or showing signs of wear. This includes the chain, the bar, the handles, and any safety guards or devices. A well-maintained chainsaw not only operates more efficiently but also significantly reduces the risk of accidents.

Step 3: Maintain a Safe Distance from the Refueling Area

When you’re ready to start your chainsaw, remember to maintain a safe distance from the fueling area. It’s recommended to start gas-powered tools at least 10 feet away from where you’ve refueled them. This precaution is to prevent any accidental ignition of fuel vapors, ensuring your safety and that of your surroundings.

Step 4: Wear Protective Gear Before Starting

Personal protective equipment is non-negotiable when operating a chainsaw. Before starting your STIHL chainsaw, ensure you are adequately equipped with safety boots, chaps, gloves, safety glasses, hearing protection, and a helmet system. Each piece of gear is designed to provide specific protection, from shielding your eyes from debris to protecting your legs from accidental cuts.

Step 5: Prepare for Interruptions During Chainsaw Operation

In the event that you are approached or need to address something while the chainsaw is running, it’s crucial to know how to handle the situation safely. Always engage the chain brake first, which stops the chain from moving. Then, shut off the engine before addressing any interruptions. This ensures that the chainsaw won’t cause harm to you or anyone else if it’s accidentally bumped or mishandled during the interruption.

Starting Procedures: How to Start Your Chainsaw Safely

Ground Starting Position: The Safest Way to Start Your Chainsaw

Place it on a clear, flat area ensuring the bar and chain are free of obstructions.
Slip the toe of your right foot into the rear handle, press down on the front handle with your left hand (thumb and fingers fully wrapped around it), and lock your elbow.
Your right hand should grip the starter handle for pulling the rope. This position is safe and recommended when you’re in a clear open area.

Standing Starting Position: Alternative Method for Starting in Tight Spaces

Place the rear handle of the saw between your legs, just above the knees.
Grip the front handle with your left hand (thumb and fingers fully wrapped around it) and keep your left arm locked.
Use your right hand to start the saw. This method is advisable when you’re not in a clear area and need to avoid twigs, brush, or debris.

How to Warm-Up a STIHL Chainsaw

To ensure a smooth start and proper functioning of your STIHL chainsaw, it’s essential to follow the correct procedures for engaging the starting controls and performing the warm-up steps. Each step is designed to prepare the chainsaw’s engine and mechanisms for safe and efficient operation. Here’s a detailed breakdown of each step:

Step 1: Engage the Chain Brake for Safety

Before initiating the start-up process, it’s crucial to engage the chain brake. This safety feature locks the chain in place, preventing it from moving during the start-up process. Engaging the chain brake minimizes the risk of accidental injury from the chain moving unexpectedly.

Step 2: Use the Purge Pump for Easy Fuel Priming (if available)

Utilizing the Purge Pump Feature (if available)

If your STIHL chainsaw is equipped with a purge pump feature, make use of it before starting the engine. Press the bulb a minimum of five times. This action draws fuel into the carburetor and circulates it back to the fuel tank, helping to prime the engine without flooding it with excess fuel.

Step 3: Activate the Decompression Valve for Easy Starting (if available)

Operating the Decompression Valve (if available)

For those using professional models equipped with a decompression valve, press this valve in before starting. This feature reduces the compression in the engine during the start-up process, making it easier to pull the starter rope and reducing the effort required to start the engine.

Step 4: Set the Master Control Lever to the Correct Start Position

The position of the Master Control Lever is crucial for starting the engine:

For Cold Starts: Grip the rear handle firmly, depress the throttle trigger interlock, and squeeze the throttle trigger. Then, move the Master Control Lever to the cold start position. This setting adjusts the engine to optimal conditions for starting when the engine is cold.
For Warm Starts: If the chainsaw was recently running and the engine is still warm, or after the chainsaw has fired, set the Master Control Lever to the warm start position. This setting is tailored for engines that don’t require the full choke used during a cold start.

Step 5: Pull the Starter Rope with the Right Technique

Gently pull the starter rope until you feel a slight resistance. At this point, provide a sharp, brisk pull and then guide the rope back into the starter housing slowly. This action should be smooth and controlled to avoid damaging the starter mechanism.

Step 6: Managing the Engine’s First Fire (Burp)

When you hear the chainsaw engine attempt to start (a “burp”), it’s time to adjust the Master Control Lever to the warm start position if it was in the cold start position. If your model has a decompression valve, press it again. Then, continue to pull the starter rope until the engine starts.

Step 7: Follow the Post-Start Procedure for Smooth Operation

Once the engine starts:

Release the Chain Brake: This allows the chain to move freely.
Warm Up the Engine: Briefly accelerate the chainsaw a few times. This step ensures that the engine reaches a suitable operating temperature and that the lubrication is distributed throughout the engine and the chain.
Re-engage the Chain Brake: Do this before you move into your cutting position. It’s a safety precaution to ensure the chain doesn’t move as you position yourself and the chainsaw for work.
