10 LOG SPLITTER
OPERATION
cauTion
Depending upon the type of wood being split, a log may
not always break into two pieces and fall to the ground.
If a log sticks to the wedge and starts to return with the
wedge during reverse, stop the cylinder retraction and
remove the wood. Care should be taken to prevent the
wood piece from falling on parts of your body.
