Yes, you can easily start your Stihl pole saw by following a few simple, crucial steps that involve proper setup, fueling, choke setting, and priming. Starting a Stihl pole saw correctly ensures it fires up quickly and runs well for trimming tall branches. This guide will walk you through the entire process, from unboxing to making that first cut, focusing on best practices Stihl pole saw operation.
Preparing Your Stihl Pole Saw for First Use
Before you even think about pulling the start cord, you must prepare your machine. Proper assembly is key for safe and effective use. If this is a brand-new unit, pay close attention to the Stihl pole pruner assembly instructions.
Checking the Fuel Mix
Stihl two-stroke engines require a specific fuel mix. Do not use straight gasoline; it will destroy the engine quickly.
Correct Fuel Ratios
Always use high-quality, fresh gasoline mixed with the correct amount of Stihl two-stroke engine oil.
- Stihl HP or HP Ultra Oil: Use a 50:1 ratio (50 parts gasoline to 1 part oil).
- Other Quality Two-Stroke Oils: Check the oil bottle instructions, but 50:1 is standard for most modern Stihl equipment.
Never mix oil and gas ahead of time for long storage. Fresh fuel mix starts the saw best.
Fueling Safely
- Ensure the engine is completely off and cool.
- Place the saw on a flat, stable surface.
- Remove the fuel filler cap slowly to release any pressure.
- Pour the fuel mixture into the fuel tank.
- Wipe up any spills immediately.
- Securely tighten the fuel cap.
Inspecting the Bar and Chain
This step is part of setting up Stihl pole saw correctly. Even new saws need checks.
Chain Tension
The chain must have the right tension before starting. A loose chain can derail, causing injury. A tight chain causes wear and poor cutting.
- Hold the tip of the guide bar slightly upward.
- Gently pull the drive link out from the bottom groove of the bar.
- The drive link should only pull out a tiny bit—about 1/8 inch maximum.
- If it hangs loose, tighten the chain adjuster nut located near the guide bar tip. Turn clockwise to tighten.
- Recheck tension after a few test cuts, as new chains stretch.
Chain Lubrication (Bar Oil)
Stihl pole saws use a separate reservoir for bar and chain oil. This oil keeps the bar cool and lubricates the chain.
- Locate the bar and chain oil filler cap (usually distinct from the fuel cap).
- Fill this reservoir with quality bar and chain oil.
- Never run the saw without bar oil, even for a short test start. It will quickly damage the chain and bar.
Assembling the Pole Sections
For Stihl telescopic pole saw guide users, proper pole connection is vital. If your model comes apart, follow these steps:
- Ensure all locking collars or clamps are clean.
- Insert the lower shaft into the upper shaft (or the powerhead connection).
- Tighten the locking collar firmly by hand or using the provided tool. It must be secure enough to prevent slippage during operating Stihl extended reach saw.
- If your model requires attaching Stihl pole saw head (the cutting attachment), align the head mount and tighten the securing bolt or quick-release mechanism until secure.
The Starting Sequence: Step-by-Step
Once the saw is fueled, oiled, and assembled, you are ready to start the engine. This sequence varies slightly depending on if the engine is cold or warm, but the fundamentals remain the same.
Safety First: Stihl Pole Saw Safety Instructions
Before pulling the cord, always follow these safety steps:
- Wear appropriate Personal Protective Equipment (PPE): Hard hat, safety glasses or face shield, hearing protection, sturdy gloves, and chaps (if cutting large limbs that might fall).
- Ensure the chain brake is engaged (pushed forward) before starting.
- Place the saw on level ground, away from flammable material.
- Ensure the saw is clear of people and pets.
Step 1: Disengage the Chain Brake
Push the front handle forward until you hear or feel a distinct click. This sets the chain brake, preventing the chain from spinning when the engine starts.
Step 2: Set the Throttle Lock
On most Stihl saws, you must set the throttle lock or the choke combination before starting.
- Push the master control lever down to the “Start” or “Cold Start” position. This usually sets the choke to the full-choke setting and partially opens the throttle.
- On many modern Stihls, this lever combines the throttle lock, choke, and stop switch functions into one accessible control.
Step 3: Priming the Engine (If Needed)
If the saw is cold or hasn’t been used recently, you need to prime the carburetor.
- Locate the primer bulb (a small rubber dome).
- Press the bulb several times (usually 3 to 5 times). You should see fuel flow into the clear bulb or see it fill slightly.
- Caution: Do not over-prime. Too much fuel can flood the engine, making starting difficult.
Step 4: Using the Choke for Cold Starts
The choke restricts air flow, creating a richer fuel mixture needed for cold starting.
- If the lever is already in the “Cold Start” position (from Step 2), the choke is set.
- If your saw has a separate choke lever, move it to the FULL CHOKE position.
Step 5: Pulling the Starter Cord
This is where technique matters for operating Stihl extended reach saw safely and efficiently.
- Grip the starter handle firmly.
- Pull the cord with a smooth, swift, full-length pull. Do not yank the cord quickly or let it snap back violently. Let the recoil rope pull the handle back slowly after the pull.
- For a cold start, you might need 3 to 5 pulls.
Step 6: Transitioning to Half-Choke (The “1st Pop”)
Once the engine attempts to fire (you hear a brief pop or sputter), the cold start setting is too rich.
- Move the master control lever (or choke lever) to the HALF CHOKE or RUN position. This opens the choke slightly, leaning out the mixture.
- Pull the starter cord again until the engine starts and runs on its own. This usually takes 1 to 3 more pulls.
Step 7: Warm-Up and Engaging the Throttle
Once the engine is running:
- Allow the engine to idle for about 30 seconds. This lets the oil circulate and the engine warm up slightly.
- Briefly squeeze and release the throttle trigger. This action automatically disengages the choke from the full-choke setting (this is sometimes called the “auto-choke reset”).
- If the saw sputters or stalls when you squeeze the throttle, return the lever to the half-choke position and restart.
Starting a Warm Engine
If the saw was running recently (within 10 minutes):
- Ensure the throttle is set to the idle position.
- The choke should be set to the RUN position (not full choke).
- If the engine feels “flooded” (it won’t fire after a couple of pulls), press the primer bulb once or twice, then pull the cord gently 3 times with the throttle in the full-open position to clear excess fuel. Then proceed normally.
Advanced Operation and Technique
Starting is just the first part. Effective use of your pole saw relies on technique.
Utilizing the Stop Switch
Learn how to use the stop switch properly. On most Stihls, pushing the master control lever all the way to the “STOP” position shuts the engine off. Never rely on engaging the chain brake to stop the saw during normal operation.
Adjusting Length for Extended Reach
When operating Stihl extended reach saw, the balance changes significantly.
- Always adjust the length while the saw is off.
- Distribute your weight evenly.
- Keep the saw close to your body for better leverage, even when fully extended.
Cutting Techniques for Pole Saws
Effective cutting reduces strain and wear on your saw. This relates directly to Stihl pole saw cutting techniques.
Cutting Position
Always stand firmly on the ground. Never stand on ladders, unsecured stumps, or unstable surfaces when operating a pole saw.
Making the Cut
- Let the saw reach full speed before touching the wood.
- Use the saw’s weight to help guide it. Do not force the cut.
- For larger branches, make an initial shallow cut (the relief cut) on the underside, then cut from the top downward (the main cut). This prevents the limb from tearing bark as it falls.
Maintaining Your Stihl Pole Saw
Proper starting sets up good maintenance habits. Regular care ensures longevity and reliable starting. Maintaining Stihl pole saw involves several key areas.
Post-Operation Shutdown
- Bring the saw to idle speed.
- Push the master control lever to the STOP position.
- Engage the chain brake by pushing the lever forward.
Cleaning After Use
Residue from sap, sawdust, and oil builds up quickly, especially around the clutch and starter housing.
- After the saw cools, clean the cooling fins and air filter. A clogged filter makes starting much harder.
- Clean the bar groove to remove packed sawdust.
Fuel System Longevity
The carburetor is the number one point of failure on small engines due to old fuel.
- Run the tank dry after every use if possible.
- If storing for over 30 days, use a fuel stabilizer or drain the fuel system completely.
Sharpening the Chain
A dull chain requires more effort to start and run, puts stress on the engine, and cuts poorly. Sharpening Stihl pole saw chain should be done frequently.
Use the correct round file size for your specific chain pitch (check your manual). File strokes should be consistent, using the angle guide stamped on the depth gauge guide plate.
Troubleshooting Common Starting Issues
If your Stihl pole saw refuses to start, follow this decision tree.
| Problem Symptom | Likely Cause(s) | Solution |
|---|---|---|
| Engine pulls but never fires (Cold) | Wrong choke setting; No fuel priming. | Verify full choke is set. Press primer bulb 3-5 times. |
| Engine “pops” once, then quits (Cold) | Choke is too rich (set too long). | Move lever to half-choke/run position. Pull cord smoothly. |
| Engine smells strongly of fuel/won’t fire (Any Temp) | Flooded carburetor. | Engage wide-open throttle. Pull starter cord 5-10 times to purge excess fuel. |
| Engine pulls easily but no ignition (Any Temp) | No spark or no fuel delivery. | Check spark plug condition. Check fuel line for clogs or cracks. |
| Engine starts but dies when throttle applied | Idle speed too low; Choke hasn’t reset. | Allow 30 seconds to warm up. Ensure lever is in the RUN position. |
Deciphering the Control Layout
Modern Stihl pole saws often feature an “AutoStart” or “ErgoStart” system, which simplifies the start process, but the basic choke control remains critical. The master control lever typically has four positions:
- STOP (0): Engine off.
- RUN (I): Half choke/Normal running position.
- COLD START (II): Full Choke.
- START: Often combines throttle lock and choke.
Always confirm the lever is fully set into the position you intend before pulling the cord. Failure to fully engage the cold start position leads to frustration.
Ensuring Proper Bar and Head Connection
When dealing with multi-piece pole saws, the connection point is crucial for safety and performance. Always ensure the attaching Stihl pole saw head mechanism is robust. If you hear rattling or feel excessive vibration during operation, immediately shut down the saw and recheck the locking collars. A loose pole section can lead to the cutting head detaching under load, a serious hazard.

Frequently Asked Questions (FAQ)
Q: How many times should I pull the starter cord before checking the choke?
A: If the saw is cold, pull the cord 3 to 5 times. Listen for a “pop.” If you hear a pop, move the control lever to the half-choke (RUN) position and pull again until it starts. If you hear nothing after 5 pulls, check if you primed it enough or if the spark plug is fouled.
Q: Can I use regular unleaded gasoline in my Stihl pole saw?
A: Yes, you can use regular unleaded gasoline (usually 89 octane or higher). However, you must mix it with the correct ratio of high-quality two-stroke engine oil, like Stihl HP oil, typically 50:1. Never run straight gasoline.
Q: Why won’t my Stihl pole saw start after it has been sitting all winter?
A: Old fuel is the most common culprit. Gasoline breaks down quickly. If fuel has been sitting for months, it clogs the small fuel lines and carburetor jets. Drain the old fuel, replace it with fresh, properly mixed fuel, and ensure the primer bulb is working.
Q: What is the best way to secure the cutting head during setup?
A: When attaching Stihl pole saw head, ensure all locking bolts or clamps are tight. Use the provided wrench or tool to secure them firmly. Visually inspect that the locking collar mechanism is fully seated before starting the engine. Vibration will quickly loosen anything that is not tight.
