4. Setup and Assembly
Before operating your DAEWOO DCS2512, proper assembly and fueling are essential.
4.1 Guide Bar and Chain Installation
- Ensure the engine is off and the chain brake is disengaged.
- Remove the chain cover by loosening the nuts.
- Place the chain around the clutch drum and guide bar, ensuring the cutting edges face forward on the top side of the guide bar.
- Fit the guide bar onto the studs, aligning the chain tensioner pin with the hole in the guide bar.
- Replace the chain cover and hand-tighten the nuts.
- Adjust chain tension using the tensioning screw. The chain should be snug but still able to be pulled freely by hand.
- Fully tighten the chain cover nuts.
4.2 Fuel and Oil Preparation
The DCS2512 uses a 2-stroke engine, requiring a specific fuel mixture.
- Fuel Mixture: Mix unleaded gasoline with high-quality 2-stroke engine oil at the ratio specified in your product documentation (typically 25:1 or 50:1, refer to the mixing bottle for guidance). Use the provided mixing bottle for accuracy.
- Chain Oil: Fill the chain oil reservoir with suitable chain lubricant. The automatic lubrication system requires a constant supply of chain oil.
Warning: Never operate the pruner without chain oil, as this will cause rapid wear to the chain and guide bar.
5. Operating Instructions
Follow these steps for safe and effective operation of your DAEWOO DCS2512.
5.1 Starting the Engine
- Place the pruner on a flat, stable surface.
- Engage the chain brake by pushing the front hand guard forward.
- Set the choke lever to the "Closed" position (full choke).
