(A) Flow Adjust - Adjusting the ow determines how
much oil is sent to cylinders and rotor. The more
oil that is sent to the rotor will result in cylinders
moving slower. If more oil is sent to the cylinders,
rotor speed will decrease. Typical adjustment is
5/8 turn out from closed position when we ship. To
adjust this, hold hex screw with hex wrench and
loosen lock nut. Turn hex screw 1/2 turn and hold
in position while tightening lock nut. Test operation
and adjust again if desired.
(B) Pressure Relief - 1/4 turn out from closed
position is approximately 3000 psi (207 bar). Relief
must be set lower than skidsteer relief. Image below
is shown with top plate removed for adjustments.
Do not operate with top plate removed.
