Important Safety Instructions
Operating a chainsaw can be dangerous if proper safety precautions are not followed. Always prioritize your safety and the safety of others.
- Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, a hard hat, gloves, and sturdy footwear. Consider leg protection (chaps) for added safety.
- Work Area: Ensure the work area is clear of bystanders, especially children and pets. Maintain a safe distance from other people and objects.
- Condition of Operator: Do not operate the chainsaw if you are tired, under the influence of drugs or alcohol, or if your judgment is impaired.
- Tool Condition: Never use the chainsaw if the chain or guide bar is damaged, dull, or improperly installed. Replace damaged components immediately.
- Grip: Maintain a firm grip with both hands on the chainsaw handles at all times during operation.
- Kickback Prevention: Be aware of the risk of kickback. Avoid cutting with the tip of the guide bar and ensure proper cutting techniques.
- Maintenance Safety: Always turn off the engine and ensure the chain has completely stopped before performing any adjustments, maintenance, or cleaning.
- Fuel Handling: Handle gasoline with extreme care. Refuel in a well-ventilated outdoor area with the engine off and cool. Avoid smoking or open flames near fuel.

Setup and Assembly
Fuel and Oil Mixture
Your chainsaw's 2-stroke engine requires a specific mixture of unleaded gasoline and 2-stroke engine oil. Always refer to the engine manufacturer's recommendations for the precise mixing ratio (e.g., 25:1, 40:1, 50:1). Using an incorrect mixture can damage the engine.
- Fuel Tank: Carefully fill the fuel tank with the prepared gasoline/oil mixture. The fuel tank capacity is 550ml.
- Oil Tank: Fill the separate oil tank with appropriate chain lubricant oil. This oil automatically lubricates the chain and guide bar during operation. The oil tank capacity is 260ml.
Guide Bar and Chain Installation
Follow the specific instructions provided in your chainsaw's engine manual for proper installation of the guide bar and saw chain. Ensure the chain is installed in the correct direction and tensioned according to the manufacturer's guidelines. A properly tensioned chain should be snug but still allow you to pull it around the guide bar by hand.
Operating Instructions
Starting the Engine
- Place the chainsaw on a firm, flat surface, ensuring the chain is clear of any obstructions.
- Engage the chain brake by pushing it forward.
- Set the choke and primer bulb according to the cold or warm starting procedure outlined in your engine manual.
- Hold the chainsaw firmly with one hand on the front handle and pull the starter cord firmly with the other hand until the engine starts.
- Once the engine starts, disengage the chain brake before beginning any cutting operations.
Cutting
Always maintain a balanced stance and a firm grip with both hands on the chainsaw handles. Allow the saw to reach full operating speed before beginning a cut. The maximum cutting length for this model is 445mm.
Control the saw by reducing pressure at the end of each stroke. This technique helps prevent the saw from binding in the wood and reduces the risk of kickback.
Stopping the Engine
To stop the engine, release the throttle trigger and engage the chain brake. Then, press the stop switch to completely turn off the engine. Ensure the chain has come to a complete stop before setting the chainsaw down.
Maintenance
Regular maintenance is crucial for the longevity and safe operation of your chainsaw.
After Each Use
- Clean the chainsaw thoroughly, removing sawdust, wood chips, and debris from the engine fins, air filter cover, and chain area.
- Lubricate the guide bar and chain. Ensure the oiler is functioning correctly.
- Check the chain tension and adjust if necessary.
Regular Checks
- Inspect the chain for sharpness and damage. A dull chain can lead to poor cutting performance and increased kickback risk. Sharpen or replace as needed.
- Check all nuts, bolts, and screws for tightness. Tighten any loose fasteners.
- Clean or replace the air filter to ensure proper engine performance.
- Inspect and clean the spark plug. Replace if worn or fouled.
Warning: Do not use the saw if the chain is damaged, dull, or improperly installed. This can lead to serious injury. Always replace damaged components with genuine Ingco parts.
