Recent Log Splitter Accident in Montgomery
Excerpt of Horrifying Log Splitter Accident in Montgomery, New York:
According to the Town of Montgomery Police Department, a man was outside operating a log splitter when the machine jammed up and stopped working. As the man started to try and clear the jam, the machine unexpectedly activated and resulted in the man's hand being severed from his arm at the wrist according to News 12. (McIntyre, 2023)
Certainly a scary incident, but unfortunately, one that happens all too often. Luckily, there are simple steps you can follow to ensure you have both hands the next day after splitting.
Release Residual Hydraulic Energy From Your Log Splitter
Now, the article does not go into detail about how the man was trying to clear the jam, but we can assume that he didn’t turn the engine off.
For those reading, always turn your log splitter’s engine off prior to servicing.
Next, move the spool that controls the push block cylinder back and forth, as far as possible in either direction, at least four times.
Lastly, hold the spool for three seconds at each limit of travel.
Releasing residual hydraulic pressure is necessary because hydraulic fluid can remain highly pressurized, even after the engine has been turned off. This high-pressure fluid can cause the hydraulics of the log splitter to function without the engine on.
If your log splitter has multiple spool valves, you will want to perform the same steps on each spool.
