Starting a new STIHL chainsaw can be a straightforward process if you follow the right steps. Whether you’re a seasoned chainsaw user or a first-time owner, this guide will provide you with clear and concise instructions to help you get your chainsaw up and running safely and efficiently.
Safety First
Before we delve into the steps for starting your new STIHL chainsaw, it’s crucial to prioritize safety. Please ensure you have the following safety gear:
- Safety Glasses: Protect your eyes from flying debris.
- Hearing Protection: Chainsaws can be loud, so safeguard your hearing.
- Gloves: Protect your hands from cuts and vibrations.
- Chainsaw Chaps or Pants: Prevent leg injuries from chainsaw kickback.
- Steel-Toed Boots: Protect your feet.
Step 1: Prepare Your Work Area
- Find a flat and stable surface to place your chainsaw, ensuring it won’t tip over during the startup process.
- Clear the area of any obstacles, debris, or tripping hazards.
- Check for proper lighting, especially if you’ll be working in dim conditions.
Step 2: Fuel and Oil Preparation
STIHL chainsaws require a fuel mixture of unleaded gasoline and two-stroke engine oil. Refer to your owner’s manual for the specific fuel-to-oil ratio recommended for your model. Usually, it’s a 50:1 ratio (50 parts gasoline to 1 part oil), but always confirm with your manual.
- Use a clean and approved fuel container.
- Measure the correct amount of two-stroke oil and add it to the container.
- Add the unleaded gasoline to the container and mix it thoroughly by shaking.
- Fill the chainsaw’s fuel tank with the mixed fuel.
Also, ensure that the chainsaw’s chain oil reservoir is filled with the appropriate bar and chain oil. This lubricates the chain and reduces friction during operation.
Step 3: Chain Brake and Controls
Before attempting to start your chainsaw, make sure the chain brake is engaged. This safety feature prevents the chain from rotating during startup.
- Push the chain brake handle forward to engage it.
- Check that the throttle trigger lockout and the stop switch are in the correct positions (usually in the "Off" position).
Step 4: Cold Start Procedure
If your chainsaw engine is cold, follow these steps:
- Place the chainsaw on a stable surface.
- Engage the chain brake.
- Press the decompression valve (if your model has one).
- Set the master control lever to the "Start" position.
- Prime the engine by pressing the primer bulb until fuel is visible in the bulb, usually 3-5 times.
- With your left hand, firmly grip the front handle, keeping your fingers clear of the front guard.
- Use your right hand to pull the starter rope. It might take a few pulls to start the engine. When it starts, disengage the throttle lockout.
Step 5: Warm Start
If the engine is already warm, follow a slightly different procedure:
- Engage the chain brake.
- Set the master control lever to the "Warm Start" position.
- Pull the starter rope with your right hand until the engine starts.
- Disengage the throttle lockout.
Step 6: Operating the Chainsaw
Once your chainsaw is started, you can release the chain brake and use it according to your needs. Remember to always maintain a firm grip, use proper cutting techniques, and follow safety guidelines.
In conclusion, starting a new STIHL chainsaw involves some simple yet critical steps. By following this guide and your chainsaw’s owner’s manual, you can ensure a safe and efficient start, whether you’re an experienced user or a first-time chainsaw owner. Always prioritize safety and wear the necessary protective gear to prevent accidents and injuries during operation.
