Bucking is the process of cutting a log into shorter lengths.
Before cutting, make sure your footing is firm and your weight is evenly distributed on both feet. When possible, raise and support the log using limbs, logs, or chocks.
WARNING: Do not buck a log that is larger than the maximum cutting thickness listed for your exact chainsaw or pole saw.
Check the Maximum Cutting Thickness
Cutting capacity varies by model. For example:
- 24V-10CS 10-inch Cordless Chainsaw: maximum cutting thickness of 9.5 inches.
- 24V-X2-CS16 16-inch Cordless Chainsaw: maximum cutting thickness of 15.5 inches.
- 24V-PS8 8-inch Cordless Pole Chainsaw: maximum cutting thickness of 7.5 inches.
- 24V 10-inch Cordless Pole Chainsaw: maximum cutting thickness of 9.5 inches.
Always confirm the maximum cutting thickness and operating procedure for your exact model before cutting.
How Do I Cut the Log?
-
Log Supported Along Its Entire Length
Cut from the top of the log. This is called overbucking.
-
Log Supported on One End
Cut approximately one-third of the log diameter from the underside first. This is called underbucking.
Then finish the cut from the top by overbucking until the two cuts meet.
-
Log Supported on Both Ends
Cut approximately one-third of the log diameter from the top.
Then finish the cut by underbucking the remaining two-thirds from below until the cuts meet.
Using the Spiked Bumper
Cordless chainsaw models equipped with a spiked bumper can use it to help control the cut.
- Plant the spiked bumper into the log and use it as a pivot.
- Cut with an arched motion to allow the guide bar to penetrate the wood.
- Repeat as necessary, changing the point where the spiked bumper is planted.
Bucking on a Slope
When bucking on a slope, always stand on the uphill side of the log.
As you near the end of the cut, reduce the cutting pressure while maintaining a secure grip on the chainsaw handles.
Do not allow the saw chain to contact the ground.
After Completing the Cut
After the cut is complete, wait for the saw chain to stop before moving the chainsaw. Stop the motor before moving from one cutting location to another.
