• Engine Displacement: 58cc (2-stroke, air-cooled)
• Output Power: 2.8kW to 3.2kW (3.8 HP)
• Bar Size: 18 Inch
• Maximum RPM: Up to 10,000 - 11,500 RPM
• Fuel Capacity: ~ 550ml
• Chain Oil Capacity: ~ 260ml
• Item Weight: ~ 7kg (15.4 lbs)     

• Automatic Oiling: Features an automatic chain lubrication system to reduce friction and extend the overall lifespan of the saw.  
• Safety Mechanisms: Built-in chain brake blocks the chain instantly in case of kickback, coupled with a dual-protection switch to prevent accidental startups. 
• Ergonomic Design: Includes an anti-vibration handle to limit user fatigue during long forestry, agriculture, or firewood-cutting sessions. 

• Fuel Mixture: Because it runs on a 2-stroke engine, you must use a proper gas-to-oil mixture. Always mix at the manufacturer-recommended ratio (typically 1:20 to 1:25) using premium 2-cycle engine oil.    
• Maintenance: Ensure the chain oil reservoir is consistently filled. Clean or replace the air filter regularly to maintain engine performance.

Frequently Asked Questions (FAQ)

Fuel & Lubrication

• What is the correct fuel mixture ratio?
  • You must mix unleaded gasoline (90 octane or higher) with premium 2-stroke engine oil. The standard ratio for a 58cc engine is 25:1 (Gasoline to Oil), unless your specific manual dictates 40:1 or 50:1. Never use pure gasoline, as it will instantly seize the engine. 
• Does it require manual chain oiling?
  • No. The machine features an automatic lubrication system that delivers a steady supply of bar and chain oil during operation. Ensure the 260ml oil reservoir is filled before every job. 

Operation & Starting

• How do I start the chainsaw easily from a cold state?
  • Flip the ON/OFF switch to ON.
  • Engage the chain brake baffle forward for safety.
  • Pull out the choke knob fully.
  • Pull the starter cord firmly until you hear the engine "pop" or cough.
  • Push the choke knob back in, and pull the cord again to start the engine. Warm it up for 30 seconds. 
• What should I check if the engine won't start?
  • Verify the fuel mix is fresh and mixed correctly. Ensure the switch is ON, check that the spark plug is clean/connected, and confirm you have not flooded the engine by leaving the choke out too long. 

Maintenance & Safety

• How tight should the chainsaw chain be?
  • The chain should fit snugly against the underside of the bar, but you should still be able to pull it up slightly by hand to reveal the drive links. A loose chain will derail, while a tight chain will burn out the bar.
• What built-in safety features does this model have?
  • It includes a quick-stop inertial chain brake to prevent injury during kickback, an ergonomic dual safety-protection throttle switch, and a robust anti-vibration system to reduce user arm fatigue during extended cutting sessions.
