Splitter Detent Adjustment
All Wolfe Ridge log splitters come with Prince valve with a pressure release detent for the return
stroke. This allows the main cylinder to retract on its own and stop when the pressure spikes at the
home position. The Prince hydraulic valve detents are somewhat sensitive to temperature, so be sure
oil temp is running between 70 and 120 degrees F before adjusting detents… If machine is cold, the
detent will kick out early, and may not kick out if the oil is very hot.
• To adjust detents on machine, locate the detent adjusters that stick up from back side of valve,
away from the handles. There is a rubber protective cap to keep moisture from entering, be sure
to put that back on after adjustments are made.
• If splitter handle kicks out before going all the way back… Use a 7/8” wrench to loosen jam nut,
and turn 5/8” adjuster screw clockwise ¼ turn to increase detent pressure. Run the splitter to
check that it is operating properly. Repeat if necessary. When machine is working correctly snug
the 7/8” jam nut to approximately 20 ft. LB of torque. DO NOT OVER TIGHTEN. Replace
rubber cap on adjustment screw.
