3.1 Sikkerhedsforanstaltninger
- Always ensure the chainsaw engine is off and cool before beginning any work.
- Frakobl tændrørskablet for at forhindre utilsigtet start.
- Brug passende personlige værnemidler (PPE), herunder handsker og øjenbeskyttelse.
- Refer to your chainsaw's original owner's manual for specific safety guidelines and procedures.
3.2 Installationstrin
This tensioner kit is a direct OEM replacement. The installation process typically involves replacing the existing tensioner assembly. Steps may vary slightly depending on your specific chainsaw model (CS-440, CS-4400, CS-5000).
- Klargør motorsaven: Place the chainsaw on a stable, flat surface. Ensure the engine is off and the spark plug wire is disconnected.
- Fjern stangdækslet: Loosen and remove the nuts securing the side cover (clutch cover/bar cover) of the chainsaw. Carefully remove the cover.
- Fjern sværd og kæde: Remove the guide bar and saw chain from the chainsaw. Note the orientation of the existing tensioner for reassembly.
- Locate and Remove Old Tensioner: Identify the old tensioner assembly. It is usually located near the guide bar mounting studs. Depending on the design, it may be held in place by a screw or simply slide out. Carefully remove the old tensioner.
- Installer ny strammer: Insert the new ECHO tensioner (Part No. 43301419830) into its designated slot on the chainsaw body. Ensure it is seated correctly.
- Insert Adjuster Screw: Thread the tensioner adjuster screw (Part No. 43301638330) into the tensioner component. Do not overtighten; just ensure it is engaged.
- Reinstall Bar and Chain: Place the saw chain back onto the clutch drum and around the guide bar. Position the guide bar onto the mounting studs, ensuring the tensioner pin engages with the hole in the guide bar.
- Reinstall Bar Cover: Sæt sidedækslet på igen, og spænd møtrikkerne med hånden. Spænd dem ikke helt endnu.
- Juster kædespænding: Proceed to the "Operating and Chain Tension Adjustment" section for proper tensioning.
4. Operating and Chain Tension Adjustment
Proper chain tension is crucial for safe and efficient chainsaw operation. The new tensioner kit facilitates this adjustment.
- Indledende spænding: With the side cover nuts hand-tightened, use a screwdriver or the appropriate tool to turn the tensioner adjuster screw. Turning it clockwise will increase tension, and counter-clockwise will decrease it.
- Kontroller spænding: The chain should be snug against the bottom of the guide bar, but still able to be pulled around the bar by hand. There should be no sag on the underside of the bar. A common test is to lift the chain from the top of the bar; the drive links should remain in the bar groove.
- Endelig stramning: Once the correct tension is achieved, fully tighten the side cover nuts securely. Re-check the chain tension after tightening, as it can sometimes change slightly.
- Post-Adjustment Check: After running the chainsaw for a few minutes, re-check the chain tension. Chains can stretch slightly when new or during initial use.
Vigtig: An overly tight chain can cause premature wear to the bar, chain, and sprocket, and can lead to overheating. An overly loose chain can derail, causing damage or injury. Always maintain correct tension.
5. Vedligeholdelse
The ECHO Chainsaw Tensioner Kit is designed for durability. Regular maintenance of your chainsaw will help ensure the longevity of this component.
- Rensning: Periodically clean sawdust and debris from around the tensioner mechanism when cleaning the guide bar and chain area.
- Smøring: While the tensioner itself typically does not require lubrication, ensure the guide bar groove and sprocket nose are properly lubricated as per your chainsaw's manual.
- Inspektion: Regularly inspect the tensioner screw and the tensioner component for signs of wear, bending, or damage. Replace the kit if any damage is observed.
