Referring to the schematic, with the Log splitter directional valve shifted for cylinder extension, pressurized fluid flows into the
cap end of the cylinder. Fluid flowing from the rod end is blocked from returning to tank by check valve C. Instead, fluid
flows through check valve D and combines with pump flow to extend the piston at high speed. When pressure in the
cylinder's cap end reaches the pressure setting of valve A, pump pressure opens it, allowing fluid from the cylinder’s
rod end to flow to tank. Check valve D prevents pump pressure from acting on the rod end of the cylinder, so full pressure
is applied to the piston from the cap end. Of course, this circuit will perform in other high/low applications.

A dirty log splitter with a clean safety record has been told its splitting days are over because it "doesn't wash with
OSH" but the "flaw in the law" has left a worker unemployed and customers without firewood in Invercargill.
Woodpeckers Firewood owner Mathew Hayes bought his diesel log splitter second-hand 10 years ago and has never had a safety
issue with the guillotine-like Vertical log splitter machinery.
