Starting a Craftsman chainsaw can seem intimidating, especially if it’s your first time or if you’re dealing with a model you’re not familiar with. Many users wonder about the specific procedures and safety precautions. This article aims to demystify the process, ensuring you can get your Craftsman gas chainsaw up and running efficiently and, most importantly, safely. We’ll cover everything from checking your fuel to the final pull of the starter cord.

Preparing Your Craftsman Chainsaw for Startup

Before you even think about pulling the starter cord, proper preparation is key. This involves checking essential components and ensuring your chainsaw is ready for operation. Think of this as your pre-flight checklist for your woodworking tool.

Fueling Your Craftsman Gas Chainsaw

The heart of any gas-powered tool is its fuel. For your Craftsman gas chainsaw, using the correct fuel mixture is paramount for both performance and longevity.

Craftsman Chainsaw Fuel Mixture Essentials

Most modern Craftsman chainsaws use a two-stroke engine, which requires a specific mixture of gasoline and two-stroke oil. Never use pure gasoline. The oil lubricates the engine’s internal parts, preventing overheating and seizure.

Gasoline: Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using old gas, as it can degrade and cause starting problems.
Two-Stroke Oil: Always use a high-quality two-stroke engine oil specifically designed for air-cooled engines. Look for oils that are designed for a 50:1 ratio, as this is common for many Craftsman chainsaws.
Mixing Ratio: The standard Craftsman chainsaw fuel mixture for most models is 50 parts gasoline to 1 part two-stroke oil (50:1). For example, if you’re using 1 gallon of gasoline, you’ll need 2.6 fluid ounces of two-stroke oil. Always consult your Craftsman chainsaw manual for the exact recommended ratio for your specific model.
Mixing Container: Use a clean, approved fuel mixing container. Add the oil first, then the gasoline. Seal the container and shake it vigorously to ensure the oil and gas are thoroughly mixed.

Important Note: Do not mix more fuel than you will use in a short period. Mixed fuel degrades over time.

Fueling Safety

Location: Always fuel your chainsaw in a well-ventilated area, preferably outdoors.
Engine Off: Ensure the engine is completely off and cool.
No Smoking: Never smoke or have open flames near fueling operations.
Spillage: Wipe up any spilled fuel immediately.

Checking and Adjusting the Chain Brake

The chain brake is a critical safety feature. It’s designed to stop the chain’s rotation instantly in case of kickback or if you release the throttle.

Engaging the Brake: To engage the chain brake, push the handguard forward towards the bar. You should feel it click into place.
Disengaging the Brake: To disengage, pull the handguard back towards the handle.
Pre-Start Check: Always ensure the chain brake is engaged before you attempt to start the chainsaw. This prevents the chain from spinning unexpectedly when the engine starts.

Inspecting the Bar and Chain

A well-maintained bar and chain are crucial for efficient cutting and safe operation.

Chain Tension: The chain should be taut but still able to be pulled around the bar by hand (with gloves on). If it’s too loose, it can derail. If it’s too tight, it can bind the engine.
- To Adjust: Loosen the bar nuts slightly. Use the adjustment screw (usually located near the bar) to tighten or loosen the chain until it’s correctly tensioned. Retighten the bar nuts. Refer to your Craftsman chainsaw manual for specific adjustments on your model.
Chain Sharpness: A dull chain is inefficient and dangerous. If your chain is dull, it will require more force to cut, increasing the risk of kickback.
Lubrication: Ensure the bar and chain are adequately lubricated. We’ll cover the oiling system in more detail later.

The Step-by-Step Process for Craftsman Chainsaw Engine Startup

Once your Craftsman gas chainsaw is properly fueled and checked, you’re ready to start the engine. Follow these steps precisely for a safe and successful startup.

Step 1: Place the Chainsaw on a Stable Surface

Find a flat, clear area with plenty of space around you.
Place the chainsaw firmly on the ground. Ensure the chain is not touching anything.
Keep both hands firmly on the chainsaw handles.

Step 2: Engage the Chain Brake

As mentioned earlier, push the chain brake handguard forward towards the bar. This is a non-negotiable safety step.

Step 3: Activate the Choke (If Applicable)

Many Craftsman gas chainsaws have a choke to enrich the fuel-air mixture for cold starts.

Cold Start: If the engine is cold, move the choke lever to the “CHOKE” or “CLOSED” position. This restricts airflow, creating a richer fuel mixture for easier ignition.
Warm Start: If the engine is already warm, leave the choke in the “RUN” or “OPEN” position. Attempting to start a warm engine with the choke on can flood it.
Choke Types: Some modern Craftsman chainsaws may have an automatic choke system or a manual primer bulb. Consult your Craftsman chainsaw manual to identify your model’s specific starting mechanism.

Step 4: Prime the Carburetor (If Equipped)

Some Craftsman gas chainsaws have a primer bulb. This small, translucent bulb on the carburetor helps to draw fuel into the engine for easier starting.

Press the primer bulb several times (usually 4-6 times) until you see fuel circulating in the bulb. This ensures fuel is present in the carburetor.
Not all Craftsman chainsaw models have a primer bulb. If yours doesn’t, skip this step.

Step 5: Set the Throttle Lock (If Equipped)

Some Craftsman models have a throttle lock or fast idle position that engages when the choke is on. This slightly opens the throttle to help the engine start.

If your chainsaw has this feature, ensure it’s activated when you move the choke to the “CHOKE” position. It will usually disengage automatically when the choke is moved to the “RUN” position.

Step 6: Pull the Starter Cord

This is where the magic happens, but it requires a steady, firm pull.

Grip: Firmly grasp the starter cord handle with one hand.
Pull: Pull the cord out steadily until you feel resistance. Then, give it a quick, sharp pull. Don’t yank the cord all the way out.
Multiple Pulls: You may need to repeat this process several times.
- Cold Engine: For a cold start with the choke on, you’ll likely hear the engine “cough” or “sputter” after a few pulls. This indicates it’s receiving fuel.
- After Sputtering: Once the engine sputters, immediately move the choke lever to the “RUN” or “OPEN” position. Then, continue pulling the starter cord until the engine starts.
- Warm Engine: If the engine is warm, ensure the choke is in the “RUN” position. You might need fewer pulls than a cold start.

Step 7: Disengage the Choke and Throttle Lock

Once the engine starts and runs for a few seconds, move the choke lever to the “RUN” or “OPEN” position.
If your model has a throttle lock, it should disengage automatically as the engine warms up or when you move the choke.

Step 8: Let the Chainsaw Warm Up

Allow the engine to run for about 10-20 seconds without engaging the throttle. This allows the engine to reach a stable operating temperature and ensures all components are ready.

Step 9: Disengage the Chain Brake

Once the engine is running smoothly, pull the chain brake handguard back towards the rear handle to disengage it. Your Craftsman chainsaw is now ready for use!

Essential Craftsman Chainsaw Safety Tips

Safety should always be your top priority when operating any chainsaw. Here are crucial Craftsman chainsaw safety tips to keep in mind:

Read Your Manual: Always refer to your specific Craftsman chainsaw manual for detailed operating instructions and safety precautions relevant to your model.
Protective Gear: Wear appropriate personal protective equipment (PPE) at all times. This includes:
- Safety Glasses or Goggles: Protect your eyes from flying debris.
- Hearing Protection: Chainsaws are loud and can cause hearing damage.
- Gloves: Provide a better grip and protect your hands.
- Chainsaw Chaps or Pants: These are designed to stop a moving chain and prevent severe leg injuries.
- Steel-Toed Boots: Protect your feet from falling objects and the chain.
- Hard Hat: Recommended for overhead hazards.
Safe Starting Area: Always start your chainsaw in a clear, flat area, away from people and flammable materials. Ensure the chain is not touching the ground or any objects.
Proper Grip: Always use a firm, two-handed grip on the chainsaw handles.
Maintain Control: Keep the chainsaw close to your body to maintain control. Never overreach.
Awareness of Surroundings: Be aware of your surroundings, including people, animals, and potential hazards like power lines or uneven terrain.
Kickback: Understand kickback. It’s a sudden, violent upward and backward motion of the chainsaw that occurs when the bar nose or tip contacts an object or when the wood closes in and pinches the chain in the cut. Always be prepared for it and never let the bar tip touch anything.
Never Operate While Tired: Fatigue can lead to accidents. Ensure you are well-rested and alert.
Do Not Operate Under the Influence: Never operate a chainsaw if you are under the influence of alcohol or drugs.
Keep Bystanders Away: Ensure no one is near your working area.

Craftsman Chainsaw Oiling System: Keeping Things Smooth

A properly functioning Craftsman chainsaw oiling system is vital for chain and bar longevity and for safe operation. The automatic oiler dispenses bar and chain oil to lubricate the chain as it moves around the bar.

Checking the Oil Reservoir

Oil Type: Use only high-quality bar and chain oil. Do not use used motor oil or other lubricants, as they can clog the oiling system.
Fill Level: Ensure the oil reservoir is filled to the appropriate level before each use. Most Craftsman chainsaws have a translucent oil tank or a clear indicator line.
When to Fill: If you notice the oiler isn’t consistently lubricating the chain during use, it’s time to check and refill the oil.

How the Oiling System Works

When the engine runs, an internal pump or mechanism draws oil from the reservoir and directs it through a channel to the bar and chain. This lubrication reduces friction, dissipates heat, and prevents the chain from becoming dull prematurely.

Check the Oil Hole: With the engine running and the chain brake disengaged, point the tip of the bar at a light-colored surface (like a piece of cardboard). A thin stream of oil should be visible being thrown off the chain. If you don’t see oil, there might be an issue with the oiling system.

Craftsman Chainsaw Maintenance for Reliable Starts

Regular Craftsman chainsaw maintenance is crucial not just for smooth operation but also for ensuring reliable starts. Neglected chainsaws are prone to starting issues.

Air Filter Cleaning and Replacement

A clogged air filter restricts airflow to the carburetor, making it difficult for the engine to start and run properly.

Location: The air filter is usually located under a cover on top of the engine.
Cleaning: Remove the air filter and tap it gently to remove loose debris. For more stubborn dirt, you can use compressed air or wash it with soap and water (ensure it’s completely dry before reinstallation). Some filters are disposable and should be replaced when dirty.
Inspection: Check the filter for damage. If it’s torn or worn, replace it.

Spark Plug Inspection and Replacement

The spark plug is responsible for igniting the fuel-air mixture. A fouled or worn spark plug can cause starting problems.

Access: Remove the spark plug cover and use a spark plug wrench to remove the plug.
Inspection: Check the electrode for wear, fouling (black, sooty deposits), or damage.
Cleaning/Gap Adjustment: You can often clean a fouled spark plug with a wire brush and ensure the gap is set according to your Craftsman chainsaw manual‘s specifications.
Replacement: If the spark plug is heavily fouled, worn, or damaged, it’s best to replace it with a new, correct spark plug.

Carburetor Adjustments

While not a regular maintenance task for beginners, a poorly adjusted carburetor can significantly impact starting.

Low-Speed and High-Speed Screws: These screws control the fuel-air mixture at different engine speeds.
Idle Speed Screw: This screw adjusts how fast the engine idles.
Professional Help: If you suspect carburetor issues, it’s often best to have a qualified technician make adjustments or clean the carburetor. Improper adjustments can damage the engine.

Checking for Fuel Leaks and Blockages

Fuel Lines: Inspect fuel lines for any cracks or leaks.
Fuel Filter: Many chainsaws have a small fuel filter inside the fuel tank. If this gets clogged, it can prevent fuel from reaching the carburetor. Refer to your Craftsman chainsaw manual for its location and how to clean or replace it.
