Amaran Keselamatan Am
- Sentiasa pakai peralatan pelindung diri (PPE) yang sesuai, termasuk cermin mata keselamatan, perlindungan pendengaran, sarung tangan dan kasut yang kukuh.
- Jangan sekali-kali mengendalikan gergaji rantai ketika keletihan, di bawah pengaruh alkohol, dadah atau ubat-ubatan.
- Keep bystanders, children, and animals at a safe distance from the work area.
- Inspect the chain saw before each use for any damage, loose parts, or fuel leaks.
- Ensure the chain brake is functional and engaged when starting the engine or moving between cuts.
Persediaan dan Perhimpunan
1. Membongkar dan Semakan Komponen
Carefully remove all components from the packaging. Verify that all parts are present and undamaged. Refer to the parts diagram (not included in this text, but typically found in a physical manual) to identify each component.
2. Fuel Mixture Preparation
This chain saw uses a 2-stroke engine and requires a specific fuel-to-oil mixture. Use high-quality unleaded gasoline and a premium 2-stroke engine oil designed for air-cooled engines. Refer to the engine manufacturer's recommendations for the exact mixing ratio (typically 25:1 or 50:1, depending on oil type). The fuel tank capacity is 560ml.
- Mix fuel in a separate, approved fuel container.
- Shake the mixture thoroughly before pouring into the fuel tank.
- Sentiasa isi minyak di kawasan yang mempunyai pengudaraan yang baik dengan enjin dimatikan dan sejuk.
3. Pemasangan Rantai dan Bar Panduan
- Pastikan brek rantai dihidupkan.
- Remove the side cover by loosening the nuts.
- Place the guide bar onto the studs, ensuring the chain tensioner pin aligns with the hole in the bar.
- Carefully fit the saw chain around the sprocket and into the guide bar groove. Ensure the cutting edges of the chain are facing the correct direction. The chain pitch is 3/8in (0.325in).
- Replace the side cover and hand-tighten the nuts.
- Adjust chain tension: The chain should be snug against the guide bar but still able to be pulled freely by hand. There should be no slack on the underside of the bar.
- Tighten the side cover nuts securely.
4. Bar and Chain Oil
Fill the oil tank (capacity 260ml) with high-quality bar and chain oil. This oil lubricates the chain and guide bar during operation, reducing friction and wear. Do not use engine oil or waste oil.
Arahan Operasi
1. Menghidupkan Enjin
The Tolsen chain saw features an easy starting system with an automatic choke.
- Letakkan gergaji rantai di atas permukaan yang rata dan kukuh. Pastikan brek rantai telah diaktifkan.
- Tekan mentol primer beberapa kali sehingga bahan api kelihatan.
- Set the choke lever to the "FULL CHOKE" position.
- Tarik kord starter dengan kuat dan stabil sehingga enjin menyala (biasanya beberapa tarikan).
- Once the engine fires, immediately push the choke lever to the "HALF CHOKE" or "RUN" position.
- Tarik kord penghidup semula sehingga enjin dihidupkan dan berjalan dengan lancar.
- Allow the engine to warm up for a few moments at idling speed (3200rpm ±5%).
- Disengage the chain brake before beginning cutting operations.
2. Operating Safety Features
- Safety Throttle Lever: This lever prevents accidental acceleration. It must be depressed along with the main throttle trigger to engage the engine.
- Rapid Reaction Chain Brake: The chain brake is a crucial safety device designed to stop the chain instantly in the event of kickback or other emergencies. Always ensure it is functional before use.
3. Teknik Memotong
Always maintain a firm grip with both hands on the chain saw handles. Stand with your feet apart for good balance. Plan your cuts to avoid kickback and ensure the tree or limb falls in the intended direction.

Rajah 2: Tolsen 20in Gasoline Chain Saw positioned for operation. This image illustrates the chain saw ready for use on the ground, demonstrating its practical application.
- Menebang: Involves making a notch cut and a felling cut to direct the tree's fall. Requires careful planning and assessment of the tree's lean and surrounding area.
- anggota badan: Removing branches from a felled tree. Work from the base of the tree towards the top, cutting smaller branches first.
- Bucking: Cutting a felled tree into sections. Support the log to prevent pinching the chain.
WARNING: Be aware of kickback. Kickback occurs when the moving chain at the tip of the guide bar contacts an object, or when the wood closes in and pinches the saw chain in the cut. This can cause a rapid, uncontrolled upward and backward movement of the guide bar towards the operator.
Penyelenggaraan
Penyelenggaraan berkala memastikan jangka hayat dan operasi gergaji rantai anda yang selamat. Sentiasa pastikan enjin dimatikan dan sejuk, dan penutup palam pencucuh ditanggalkan sebelum melakukan sebarang penyelenggaraan.
1. Pembersihan Penapis Udara
The chain saw is equipped with a long-life air filter that can be cleaned repeatedly. A dirty air filter reduces engine performance and increases fuel consumption.
- Tanggalkan penutup penapis udara.
- Tanggalkan elemen penapis udara dengan berhati-hati.
- Clean the filter by tapping it gently or using compressed air. For heavily soiled filters, wash with warm soapy water, rinse thoroughly, and allow to dry completely before reinstallation.
- Reinstall the dry air filter and secure the cover.
2. Chain Sharpening and Tension
- Mengasah: A sharp chain is crucial for efficient and safe cutting. Sharpen the chain regularly using a round file of the correct diameter for the chain pitch (3/8in or 0.325in). Follow the manufacturer's recommended sharpening angles.
- Ketegangan: Check chain tension frequently. A properly tensioned chain should be snug against the guide bar but still allow you to pull it around the bar by hand. Adjust as needed.
3. Pemeriksaan Palam Pencucuh
Inspect the spark plug periodically. Clean any carbon deposits and check the electrode gap. Replace the spark plug if it is fouled or worn.
4. Pembersihan Am
After each use, clean the chain saw thoroughly. Remove sawdust, debris, and oil residue from the engine fins, air intake, and around the chain and guide bar. This prevents overheating and ensures proper operation.
