- The form of the bar
- The accuracy required
Measuring from the Bar Tip to the Chain Tensioning Mechanism
This technique entails measuring the gap from the tip of the bar to the middle of the chain tensioning mechanism. This is an in depth information:
1. Guarantee Bar and Chain are Clear
Take away any particles or sawdust from the bar and chain to make sure correct measurements.
2. Find Bar Tip
Establish the sharpest level on the finish of the bar. This is called the bar tip.
3. Find Chain Tensioning Mechanism
Discover the mechanism that adjusts the chain pressure. That is usually a knob or lever positioned close to the bottom of the chainsaw.
4. Measure from Bar Tip to Middle of Chain Tensioning Mechanism
Utilizing a measuring tape, fastidiously measure the gap between the bar tip and the middle of the chain tensioning mechanism. Maintain the tape taut however keep away from making use of extreme strain that would harm the tape or bar. Document this measurement in inches or centimeters.
Instance: If the gap from the bar tip to the middle of the chain tensioning mechanism is 16 inches, then the bar size is 16 inches.
Utilizing a Yardstick or Measuring Tape
To make use of this technique, you have to a yardstick or a measuring tape and a flat floor. Place the chain noticed on the flat floor with the blade going through up. Place the yardstick or measuring tape on the base of the bar, the place it meets the physique of the noticed. Prolong the yardstick or measuring tape to the tip of the bar and skim the measurement. This provides you with the bar size.
Step 1: Put together the chainsaw
Earlier than you start, make sure the chainsaw is turned off and cooled down. Seek advice from your chainsaw’s consumer guide for particular directions on how one can safely put together it for upkeep.

Step 4: Find the start line
Establish the bottom of the bar, the place it meets the physique of the chainsaw. That is the place you’ll start your measurement.
Step 5: Measure the bar size
Place the yardstick or measuring tape on the base of the bar. Prolong it to the tip of the bar, guaranteeing it stays parallel to the bar’s edge. Learn the measurement on the tip to find out the bar size. Repeat the measurement to verify accuracy.
Step 6: Document the measurement
Observe down the measurement you obtained. This would be the size of the chainsaw bar.
Adjusting for Chain Overhang
To correctly measure the bar size of a chainsaw, it is necessary to regulate for chain overhang. This refers back to the size of the chain that extends past the tip of the information bar. When measuring bar size, the overhang shouldn’t be included.
Calculating Chain Overhang
To calculate chain overhang, observe these steps:
| Step | Description |

| 2 | Loosen the chain pressure till it’s slack |
| 3 | Pull the chain away from the bar till it’s absolutely uncovered |
| 4 | Measure the gap between the tip of the information bar and the top of the chain |
This distance represents the chain overhang.
Adjusting for Overhang When Measuring Bar Size
When measuring bar size, subtract the chain overhang from the full size of the chain. For instance, if the chain measures 24 inches and the chain overhang is 2 inches, the bar size can be 22 inches.
Verifying Measurements with a Bar Gauge
Utilizing a bar gauge is a extra exact technique of verifying the size of your chainsaw bar. Bar gauges can be found in varied sizes and may be discovered at most {hardware} shops or on-line retailers. To make use of a bar gauge, observe these steps:
- Place the bar gauge on the bar, aligning the top of the gauge with the tip of the bar.
