STIHL chainsaws, renowned for their durability and performance, can sometimes be a challenge to start, especially under cold conditions. Properly cold-starting your chainsaw ensures safety, prolongs the life of the machine, and gets you back to your tasks with minimal fuss. Here’s a straightforward guide on how to cold start your STIHL chainsaw.
1. Safety First
Before you begin:
Ensure you’re wearing appropriate safety gear: gloves, safety glasses, and protective footwear.
Ensure the chainsaw is on a stable surface, and there’s no immediate danger of the chain contacting any object.
2. Pre-Start Checks
Fuel and Oil: Check the fuel and chain oil levels. Refill if necessary using the recommended oil and fuel mix.
Chain Brake: Engage the chain brake by pushing the front handguard forward until it clicks.
3. Setting the Choke
Locate the choke control lever.
Move the lever to the "Cold Start" or "Choke" position. This setting enriches the fuel mixture, facilitating easier ignition in cold conditions.
4. Primer Bulb (If Available)
- Press the primer bulb several times until you see fuel inside it. This action purges air from the carburetor and fuel system.
5. Starting Procedure
Place the chainsaw on the ground. Ensure the bar and chain are clear of any obstructions.
Firmly grip the front handle with your left hand.
Place your right foot in the rear handle to keep the chainsaw stable.
Using your right hand, pull the starter rope briskly until you hear the engine attempt to start (a "pop" or brief sputter).
6. Adjusting the Choke
Once you hear the engine’s initial firing, immediately move the choke lever to the "Half Choke" or "Warm Start" position.
Pull the starter rope again. The chainsaw should now start running.
7. Setting to Run
Once the chainsaw is running, blip (quickly press and release) the throttle. This action will disengage the choke and set the engine to its normal running position.
Release the chain brake by pulling the front handguard back toward the handle before using the chainsaw.
8. If Chainsaw Doesn’t Start
If the chainsaw doesn’t start after several pulls:
Reset the choke to the "Cold Start" position and repeat the process.
If it still doesn’t start, it may be flooded or there might be another issue that needs troubleshooting.
9. Conclusion
Cold starting a STIHL chainsaw might seem daunting at first, but with the right technique, it becomes a routine task. Always prioritize safety and follow the manufacturer’s instructions provided in the user manual. With consistent maintenance and proper starting techniques, your STIHL chainsaw will serve you efficiently for years to come.
