Step-by-Step: How to Properly Start a Stihl Chainsaw
Preparation and Safety Checks
- Confirm the chainsaw is on a flat, stable surface.
- Engage the chain brake to prevent accidental movement.
- Inspect the chainsaw for damage, loose parts, or dull chain.
Fuel and Oil Check
- Verify the fuel mixture (use fresh, correctly mixed fuel).
- Ensure the chain oil reservoir is full to prevent damage during operation.
Activate the Chain Brake
- Engage the front handguard forward to lock the chain brake.
Set the On/Run Switch
- Locate the switch (usually on the side or front panel).
- Move the switch to the “On” or “Run” position.
Prime the Carburetor (if applicable)
- Press the primer bulb 5-6 times until fuel appears visibly.
- Note: Some models may not have a primer bulb; refer to your manual.
Set the Choke
- For cold starts: move the choke lever to the “Full Choke” position.
- For warm starts: the choke may be in the “Open” or “Half Choke” position to speed up the process.
Start the Chainsaw
- Place the chainsaw firmly on a flat surface, holding it with your foot if necessary.
- Firmly grip the rear handle with your dominant hand.
- With your other hand, pull the starter cord briskly until the engine sputters or starts.
- Do not yank the cord excessively to prevent damage.
Adjust the Choke and Throttle
- Once the engine runs, gradually move the choke to the “Open” position.
- Squeeze the throttle trigger slightly to keep the engine running smoothly.
Disengage the Chain Brake
- Before cutting, release the chain brake by pulling the front handguard back.
Ready to Use
- Your chainsaw is now operational. Keep a firm grip and maintain awareness of safety protocols.
Tips for Success
- Always use fresh fuel and proper mix ratios.
- Warm up a cold engine gradually, especially in cold weather.
- Use two hands when starting for maximum control.
- Keep your chainsaw on a flat, stable surface during startup.
- Regularly inspect and maintain your chainsaw for optimal performance.
Common Mistakes and How to Avoid Them
| Mistake | Consequence | Solution |
|---|---|---|
| Starting with a dirty or dull chain | Increased risk of kickback and inefficient cutting | Sharpen or replace the chain regularly |
| Ignoring safety checks | Accidents or injury | Perform a thorough safety inspection before each use |
| Not engaging the chain brake during startup | Risk of accidental movement | Always engage the brake before starting |
| Yanking the cord excessively | Damage to pull cord or starter | Use controlled, firm pulls and stop if resistance increases |
| Forgetting to turn on the On/Run switch | Engine won’t start | Double-check the switch position before pulling the starter cord |
