Problem
Blade is moving too fast. The blade seems to move
too fast in Control Mode. The Grade Indicator skips
through on-grade.
Causes Solutions
The Valve Gain
setting is too high.
Decrease the Valve Gain setting,
which will cause the hydraulics
to respond slower.
Check which side control is fast
before adjusting the Valve Gain.
Remember that the lower
number setting slows down the
response.
