Важлива інформація з безпеки
УВАГА: Chainsaws are dangerous tools that can cause severe injury or death if not used properly. Always follow the safety guidelines provided by your chainsaw manufacturer in addition to these chain-specific instructions.
- Always wear appropriate personal protective equipment (PPE), including a helmet, eye protection, hearing protection, gloves, and chainsaw protective trousers/chaps.
- Ensure the chainsaw is turned off and the spark plug cap is disconnected (for gas models) or the battery is removed (for electric models) before performing any maintenance or chain replacement.
- Inspect the chain, guide bar, and sprocket for damage or wear before each use. Replace worn or damaged components immediately.
- Maintain proper chain tension. A loose chain can derail and cause injury; an overly tight chain can cause premature wear and damage.
- Будьте обережні з віддачею та вживайте запобіжних заходів, щоб її уникнути.
- Тримайте сторонніх осіб, особливо дітей та домашніх тварин, подалі від робочої зони.
Setup: Chain Installation
Follow these steps to safely install your new TrueCut chainsaw chain:
- Підготуйте бензопилу: Ensure the chainsaw is off, the engine is cool, and the spark plug cap is disconnected or battery removed. Engage the chain brake.
- Remove Guide Bar Cover: Loosen and remove the nuts holding the guide bar cover in place. Carefully remove the cover.
- Зніміть старий ланцюг та направляючу шину: Remove the old chain from the sprocket and guide bar. Then, remove the guide bar itself.
- Чисті компоненти: Clean any sawdust, debris, or old oil from the sprocket, guide bar groove, and guide bar mounting area.
- Встановлення нового ланцюга: Place the new TrueCut chain onto the sprocket, ensuring the cutting edges (rakers) are facing the correct direction (usually forward, away from the chainsaw body, on the top of the guide bar).
- Mount Guide Bar: Slide the guide bar onto the mounting studs, ensuring the chain fits into the guide bar groove. The chain tensioner pin should align with the hole in the guide bar.
- Replace Guide Bar Cover: Reinstall the guide bar cover and hand-tighten the nuts. Do not fully tighten yet.
- Регулювання натягу ланцюга: Using the chain tensioning screw (typically located on the side of the chainsaw or on the guide bar cover), adjust the chain tension. The chain should be snug against the guide bar, but you should be able to pull the chain freely around the guide bar with gloved hands. There should be no slack on the underside of the guide bar, and the drive links should not come out of the guide bar groove.
- Остаточне затягування: While holding the tip of the guide bar up, fully tighten the guide bar nuts.
- Check Tension Again: After tightening, re-check the chain tension. It may change slightly. Adjust if necessary.

Once the TrueCut chain is correctly installed and tensioned, you can operate your chainsaw according to its manufacturer's instructions. Remember these chain-specific considerations:
- Змащення: Ensure your chainsaw's automatic oiler is functioning correctly and filled with appropriate bar and chain oil. Proper lubrication is critical for chain performance and longevity.
- Період обкатки: New chains may stretch slightly during the first few uses. Frequently check and adjust chain tension during the initial break-in period (first 30 minutes of operation).
- Техніка різання: Always use proper cutting techniques to avoid kickback and ensure efficient cutting. Do not force the chain; let the chain do the work.
- Avoid Contact with Ground/Obstacles: Do not allow the chain to contact soil, rocks, or metal objects, as this will dull the chain quickly and can cause damage.
