HYDRAULIC DEPTH CONTROL
The optional cylinder package purchased with your drill
contains a hydraulic cylinder with depth control stop, Fig.
6. This cylinder allows for a variable adjustment from zero
to maximum stroke which controls the down pressure ap-
plied to your disk openers. In order to adjust the stroke of
the cylinder, retract cylinder until the openers are set at
the desired down pressure required. Next, loosen the bolt
on the depth control actuator plate and slide it down the
cylinder until it stops against the plunger of the control
valve on the head of the cylinder. You will now need to ex-
tend the cylinder slightly and move the depth control actu-
ator plate down to compensate for the control valve
plunger length.
