CAUTION: Excessive operating speed can cause damage or injury. Full extension or retraction of cylinder must take at least 2 sec.

Adjust rate of operation for each job.

Change flow setting as follows:

  1. Select SCV selection button (A) for SCV being used. Display under SCV selection buttons displays previous rate of flow.

    NOTE: To provide operator with additional indication of command setting, as operator turns flow adjustment dial (B) through flow settings, display increases or decreases number of line increments as flow changes.

  2. Turn flow adjustment dial clockwise to increase flow or counterclockwise to decrease flow. Flow setting is shown on bar graph display (C) when adjustments are made.

NOTE: SCV can be operated to observe flow rate while in adjustment mode. If total flow demand exceeds available pump flow, reduced cylinder cycle times or a reduction in motor speed results.
