ADJUSTMENT OF THE FEED SPEED

The feed speed must be set with
the chipper running. Please
!
observe the following safety
instructions:
DANGER!
• Never stand in front of the feed hopper! Set the
feed speed when standing to the left of the feed
unit.
• The feed speed must only be adjusted when the
feed unit is idling. During the adjustment, material
must not be loaded.
• Exercise extreme caution when adjusting the sys-
tem. The emergency stop switch located next to
the control valve is used to stop material feed in
case of emergency.
Use the control valve to adapt the speed of the feed
roller to the speed of the cutting disk.
• Turn the knob counterclockwise to increase the
speed and turn in clockwise to decrease the speed.
See fig.
• After having adjusted the feed speed, re-check it
while observing the valid safety regulations.
• The feed speed is correctly adjusted when the
material does not butt against the cutting disk or
when the tips of the feed roller do not slow down
the material feed.
