(A) Flow Adjust - Adjusting the flow determines
how much oil is sent to cylinders and blade.
The more oil that is sent to the blade will result
in cylinders moving slower. If more oil is sent to
the cylinders, blade speed will decrease. Typical
adjustment is 1/2 turn out from closed position. To
adjust, hold hex screw with hex wrench and loosen
lock nut. Turn hex screw and hold in position while
tightening lock nut. Test operation and adjust again
if desired.
(B) Pressure relief must be set lower than
machine relief. 1/4 turn out from closed position
is approximately 3000 psi (207 bar). To adjust,
hold hex screw with hex wrench and loosen lock
nut. Turn hex screw in to increase pressure, or
out to decrease pressure. Turn hex screw in 1/4
turn increments until desired pressure is achieved.
Hold hex screw in position while tightening lock
nut.
