Automatic	Oil pump delivers oil to the chain

Adjusting the Tension

Proper chain tension is crucial for safety and efficient cutting. Follow these steps to adjust the tension:

Loosen the tension adjustment knob: On the side of the saw, locate the knob that secures the chain bar to the body. Turn it counterclockwise to loosen it.
Tighten the chain by hand: Grasp the chain at the bottom of the bar and pull it towards you. The chain should be snug but not so tight that it cannot move freely.
Use the tension adjustment screw (Optional): Some chainsaws have an additional screw on the side of the bar that allows for fine-tuning the tension. Turn the screw clockwise to tighten or counterclockwise to loosen.

Tension Indicator	Description
Too Loose	The chain sags significantly and makes a rattling noise when running.
Too Tight	The chain is difficult to move and creates excessive heat and friction.
Correct	The chain moves smoothly with minimal sag and produces a soft hum when running.

Retighten the tension adjustment knob: Once the chain is adequately tensioned, tighten the adjustment knob clockwise.
Check the tension by lifting the tip of the bar: The chain should not sag more than 1/2 inch (1.27 cm) when lifted. If it does, adjust the tension further.
Run the saw for a few minutes and recheck the tension: The chain may stretch slightly as it runs, so it’s essential to double-check the tension after a short period of operation.

Verifying Tension

Once the chain is attached to the chainsaw, it is crucial to verify its tension. Proper tension ensures optimal performance and safety. Here are some key pointers to guide you through the tension verification process:

2. Manual Test

Gently pull the chain by hand in the direction of its travel. It should provide some resistance but still move smoothly with minimal effort. If the chain is too tight, it can increase friction, reduce chain speed, and put strain on the motor. Conversely, if it is too loose, it may slip or jump during operation.

3. Using a Tensioning Tool

Some chainsaws come equipped with a tensioning tool that aids in setting the proper chain tension. Follow the manufacturer’s instructions for using this tool, as it varies between different models.

4. Measuring with a Chain Tension Gauge (Optional)

For a more precise measurement, consider using a chain tension gauge. This device provides a numerical reading of the chain tension, ensuring accuracy and consistency. To use the gauge, place it between the chain and the bar, following the manufacturer’s guidelines. The gauge should indicate an appropriate tension range, typically specified in inches of deflection.

Chain Tension	Deflection Measurement
Loose	1/4 to 3/8 inch
Optimal	1/8 to 1/4 inch
Tight	Less than 1/8 inch

Note: Always refer to the manufacturer’s recommendations for your specific chainsaw model regarding chain tension.
