Making certain the right match of your chainsaw bar is essential for optimum efficiency and security. However how do you precisely measure the bar’s size to make sure an ideal match? Here is a complete information that will help you decide the precise measurement.
First, familiarize your self with the 2 major sorts of chainsaw bars: nostril bars and full-skip bars. Nostril bars function a reducing head on the tip, whereas full-skip bars have tooth alongside your entire size. Measure the bar’s size by extending a measuring tape or ruler from the nostril of the bar (the pointed finish) to the tail (the tip reverse the nostril). Be aware that the measurement contains the nostril or tail, relying on the kind of bar.
Moreover, it is important to think about different components that may have an effect on the match of a chainsaw bar. These embody the chain’s pitch, the gauge, and the variety of drive hyperlinks. Matching the bar’s specs to the chain ensures compatibility and optimum reducing efficiency. Skilled arborists and forestry specialists extremely suggest utilizing a bar and chain mixture really useful by the chainsaw producer. By adhering to those tips, you possibly can guarantee a secure and environment friendly chainsaw operation.
Getting ready the Chainsaw for Measurement
Earlier than measuring the bar on a chainsaw, it is essential to arrange the device and guarantee its security. Observe these detailed steps to make sure an correct and secure measurement course of:
Security Precautions
- Put on acceptable security gear, together with eye safety, gloves, and earplugs.
- Disconnect the spark plug wire to forestall unintentional beginning throughout measurement.

Eradicating the Chain
For correct measurement, the chain have to be faraway from the chainsaw. To do that:
- Loosen the chain tensioner knob or bolts.
- Take away the bar cowl and slide the chain out of the information bar.
- Lay the chain apart for later reinstallation.
Measurement Methods
Measuring Bar Size
With the chain eliminated, now you can measure the size of the bar. Place the tip of a measuring tape flush in opposition to the within fringe of the bar, the place the chain would usually relaxation. Run the tape measure alongside the size of the bar, stopping on the different inside edge. File the size in inches or centimeters.
Measuring Bar Gauge
The bar gauge refers back to the thickness of the bar. To measure this:
- Place a caliper over the bar’s edge the place the chain would run.
- Shut the caliper jaws till they contact the bar’s edge.
- Learn the measurement on the caliper’s scale. File the gauge in both millimeters or inches.
Security Issues
Put on acceptable protecting gear
All the time put on correct security gear when measuring the bar on a chainsaw, together with gloves, eye safety, and earplugs. Chainsaws could be harmful instruments, so it’s important to take precautions to keep away from harm.
Securely maintain the chainsaw
When measuring the bar on a chainsaw, make sure the chainsaw is turned off and the chain is just not engaged. Maintain the chainsaw firmly with each arms, one hand on the entrance deal with and the opposite on the rear deal with.
Use a tape measure
Use a versatile tape measure to measure the size of the bar. Begin by putting the tip of the tape measure on the base of the information bar, the place it meets the chainsaw physique. Then, prolong the tape measure alongside the size of the bar, retaining it straight and parallel to the bar.
Learn the measurement
Learn the measurement on the tape measure on the finish of the bar. The measurement can be in inches or centimeters, relying on the tape measure used.
Extra ideas
Listed below are some extra ideas for measuring the bar on a chainsaw:
| Ideas | Description |
|---|---|
| Use a metric tape measure | Metric tape measures are extra correct for measuring the bar on a chainsaw. |

Components Affecting Bar Size Measurement
9. Chain Rigidity
Correct chain rigidity is essential for correct bar size measurement. A free chain can wrap across the tip of the bar and throw off the measurement. Conversely, an over-tightened chain can stretch, leading to an incorrect studying. To make sure correct measurements, alter the chain rigidity based on the producer’s specs earlier than measuring the bar.
| Rigidity Sort | Description |
|---|---|
| Correct rigidity | The chain must be agency however not overtight. It ought to have about 1/4 to 1/2 inch (6 mm to 12 mm) of play when pulled on the midpoint between the information bar and the tip. |
| Unfastened rigidity | The chain is just too free and can wrap across the tip of the bar when reducing. This could trigger the chain to leap off the bar and create a security hazard. |
| Over-tight rigidity | The chain is just too tight and is stretched. This could trigger the chain to interrupt or the motor to overheat. |
Measuring Bar Size
To precisely measure the bar on a chainsaw, comply with these steps:
