3. Setup and Assembly

3.1 Unpacking and Initial Inspection

Carefully remove all components from the packaging. Inspect for any damage that may have occurred during shipping. Ensure all parts listed in the packing list are present.

3.2 Fuel and Oil Mixture

This chainsaw requires a specific fuel mixture. Use fresh unleaded gasoline mixed with a high-quality 2-cycle engine oil at a ratio of 50:1 (2.6 oz of oil per gallon of gasoline). Do not use E85 fuel or automotive oil. Always mix fuel in a separate, approved container.

• Fill the fuel tank (marked with a fuel pump icon) with the prepared fuel mixture.
• Fill the chain oil tank (marked with an oil can icon) with quality bar and chain lubricant. Do not use waste oil.

3.3 Chain Tension Adjustment

Proper chain tension is crucial for safe and efficient operation. The chain should be snug against the guide bar, but still able to be pulled around by hand with light effort. There should be no slack on the underside of the guide bar.

1. Loosen the two bar nuts on the side cover.
2. Turn the tensioning screw (usually located near the bar nuts) clockwise to tighten the chain, or counter-clockwise to loosen it.
3. Once the correct tension is achieved, tighten the bar nuts securely.
4. Recheck chain tension after the first few cuts, as new chains can stretch.

4. Operating Instructions

4.1 Starting the Chainsaw (Cold Engine)

1. Place the chainsaw on a firm, flat surface.
2. Engage the chain brake by pushing the front hand guard forward.
3. Push the primer bulb 6-10 times until fuel is visible in the return line.
4. Pull the choke lever out to the FULL CHOKE position.
5. Pull the starter rope firmly and steadily until the engine "pops" or attempts to start (usually 1-3 pulls). Do not pull the rope to its full extension.
6. Push the choke lever in to the HALF CHOKE position.
7. Pull the starter rope again until the engine starts.
8. Once the engine starts, immediately push the choke lever fully in to the RUN position.
9. Allow the engine to warm up for a few moments before disengaging the chain brake and beginning work.

4.2 Cutting Techniques

Always maintain a firm grip with both hands on the chainsaw handles. Stand with your feet shoulder-width apart for balance. Plan your cuts to avoid kickback and ensure the tree or limb falls in the intended direction.

4.3 Stopping the Chainsaw

To stop the engine, release the throttle trigger and move the ON/OFF switch to the OFF position. Engage the chain brake immediately after stopping the engine.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your chainsaw. Always disconnect the spark plug wire before performing any maintenance.

5.1 Chain Sharpening

A sharp chain is essential for efficient cutting and to prevent kickback. Sharpen the chain regularly using a round file of the correct diameter (typically 5/32 inch for 3/8 inch low profile chain) and a flat file for depth gauges. Consult a professional if unsure.

5.2 Air Filter Cleaning

Clean the air filter after every 5 hours of operation, or more frequently in dusty conditions. Remove the air filter cover, take out the filter, and clean it with warm, soapy water. Allow it to dry completely before reinstalling.

5.3 Spark Plug Inspection

Inspect the spark plug every 25 hours of operation. Clean any carbon deposits and check the electrode gap. Replace the spark plug annually or if it shows signs of wear or damage.

5.4 Guide Bar Maintenance

Regularly clean the guide bar groove to remove sawdust and debris. Flip the guide bar periodically to ensure even wear. Check for burrs on the guide bar rails and file them smooth if present.
