- Mark the Chopping Ends: Utilizing a tape measure or marking software, mark the factors the place the irregular ends of the bar would meet if the bar have been complete.
- Measure the Size: Measure the gap between the 2 marks made in step 2. This supplies the efficient slicing size of the bar.
- Add the Nostril Size: For bars with a nostril that extends past the slicing tooth, add the size of the nostril to the measurement obtained in step 3.
- Subtract the Tail Size: If there’s a tail on the bar that’s not used for slicing, subtract its size from the measurement obtained in step 4.
- Spherical Up: Spherical the ultimate measurement as much as the closest inch or millimeter to make sure accuracy.
- Verify for Irregularities: Examine the irregular ends for any vital put on or injury that would have an effect on the slicing efficiency. Think about changing the bar if the injury is extreme.
- Think about the Drive Hyperlink Rely: If you’re buying a brand new chain to exchange the one on the bar, make sure that the drive hyperlink rely matches the size of the bar you measured.
- Use a Conversion Chart: Confer with a conversion chart to find out the suitable bar size in your particular chainsaw mannequin.
Measurement Technique Efficient Chopping Size Mark and measure the factors the place irregular ends would meet if the bar have been complete Nostril Size Measure the size of the nostril (if any) and add it to the efficient slicing size Tail Size Subtract the size of the tail (if any) from the efficient slicing size Guaranteeing an Correct Bar Measurement
