SCRAPE LOCK ADJUSTMENT
NOTE: The HS Compact Plow snowplow's
manifold has a built-in blade scrape lock
feature that is factory set. See your sales outlet
for HS Compact Plow scrape lock adjustment.
HT Series™ Snowplows:
Follow the instructions
below to increase the pressure setting of the
blade's scrape lock feature. The snowplow must
be attached to the vehicle and the snowplow
battery cable and lighting harness must be
connected before beginning this procedure.
1. Park the vehicle on a smooth, level, hard
surface, such as concrete. Lower the blade to
the ground and turn the control OFF. Turn the
vehicle ignition to the "OFF" position.
2. Disconnect the snowplow battery cable from
the vehicle battery cable.
3. Remove the hydraulic unit cover.
