Mengendalikan Gergaji Berantai
1. Langkah-langkah Keselamatan
Always prioritize safety when operating a chainsaw. Wear appropriate personal protective equipment (PPE) including safety glasses, hearing protection, gloves, and sturdy footwear. Ensure a clear work area and be aware of your surroundings.
2. Memulakan Gergaji Berantai
- Pastikan bateri dicas sepenuhnya dan dipasang dengan kukuh.
- Pegang gergaji dengan kuat dengan kedua-dua belah tangan.
- Engage the safety lock-off button, then squeeze the trigger to start the chain.
3. Teknik Memotong
The 16-inch chain runs at speeds of up to 49 feet per second, providing efficient cutting. Always maintain a firm grip and stable footing. Avoid cutting above shoulder height. For larger limbs or trees, plan your cuts carefully to prevent kickback and ensure the wood falls safely.

Penyelenggaraan
Penyelenggaraan tetap memastikan jangka hayat dan operasi yang selamat gergaji anda.
1. Ketegangan Rantai
Proper chain tension is crucial. A chain that is too loose can derail, and a chain that is too tight can cause excessive wear and damage. Adjust the chain tensioning knob until the chain is snug against the guide bar but can still be pulled freely by hand.
2. Pembersihan
After each use, remove the battery and clean the chainsaw. Use a brush or compressed air to remove sawdust, chips, and debris from the motor housing, chain, and guide bar. Wipe down all surfaces with a damp kain.
3. Bar and Chain Oil
Regularly check the oil level in the auto-oiling system and refill as needed. Use only high-quality bar and chain oil.
Menyelesaikan masalah
- Gergaji rantai tidak bermula: Ensure the battery is fully charged and properly inserted. Check that the safety lock-off button is engaged before squeezing the trigger.
- Chain is not cutting efficiently: Check chain tension. Ensure the chain is sharp and free of damage. Verify the oil reservoir is filled.
- Getaran berlebihan: Inspect the chain and guide bar for damage or improper installation. Ensure all components are securely fastened.
