from the lift ram base hose. Reconnect the lift
ram base hose to the manifold and tighten it
securely.

10. Lower the fl oor jack. Turn the control ON and
lower the blade onto the jack.
11. If the pressure reading obtained in Step 9 was
less than 210 psi, turn the scrape lock (RV2)
valve stem clockwise 1/4 turn.
If the pressure reading obtained in Step 9 was
more than 210 psi, turn the scrape lock (RV2)
valve stem counterclockwise 1/4 turn.
NOTE: Adjustments should be made in 1/4-turn
increments.
12. Repeat Steps 9–11 until the recommended
scrape lock pressure (210 psi) is achieved.
NOTE: Adjusting the scrape lock pressure
in excess of the recommended pressure will
increase amperage draw and will shorten the
life of the plow motor.
13. Once the recommended pressure is achieved,
remove the fl oor jack, lower the blade
completely, and turn the control OFF. Turn
the vehicle ignition to the "OFF" position.
CAUTION
Do not mix diff erent kinds of hydraulic
