block.
•
Reduce engine RPM to idle.
•
Raise cutterhead clear of stump.
•
Engage cutterhead drive belts by
pushing down on engagement handle to
relieve pressure on engine slide stop.
Lift slide stop and slowly pull handle
back to engage belts.
•
Increase engine RPM to full.
•
Test controls for proper operation,
speed, and unobstructed movement.
•
Cutter head swing speed should be
adjusted to a rate that will allow cutter
wheel to pass through stump smoothly.
If jerking, bouncing or significant drops
in engine speed occur, swing rate is too
rapid and must be decreased.
•
Swing speed should be determined and
adjusted with the controls in the full
open position.
•
A counter-rotating valve is located
within the hydraulic system to adjust this
speed. Turning the handle counter-
clockwise will open the bypass and slow
swing action. Turning it clockwise will
increase swing rate.
