ROTATING KNIVES!

the feed chute with hands or
feet.
FIRE HAZARD! Always keep
DGHTXDWH¿UH¿JKWLQJ
equipment on hand when
using the chipper.
Check the outside
temperature of the chipper
regularly. If the chipper heats up abnormally,
stop the chipper and determine the cause of
the overheating.
Check the temperature of bearings regularly.
Pay special attention to careful maintenance,
and keep the chipper free from dust.
If the chipper starts smoking, pour water
down the feed chute.
REDUCING THE POWER DEMAND
When using a small tractor to power the CH160
chipper, select a PTO speed of 540 rpm. Run the
tractor at full engine speed.
If the tractor’s engine speed still decreases during
chipping, reduce power demand by altering the
chipper to cut with one knife.
The chipper is altered for single-knife operation
simply by removing one knife and attaching it to
the other side of the disk as a counterbalance, to
retain the balance of the disk.
Since the chipper is self-feeding, the feed speed
of wood is also halved.
See Sections “Removing the upper chamber”
and “Sharpening the knives”.
Place a spring washer on the bolt. Turn the
lock nut on the bolt and tighten to 45 Nm.
Place another spring washer on the bolt and
turn the bolt through the knife into the disk.
See Fig. 14. Tighten the bolts to 45 Nm. Attach
the knife using all four bolts.
Interchange the cutting and counterbalance
knives regularly to ensure the balance of the
disk.
