If a wood jams inside the chipper, cut the
engine, remove the keys and wait for all
movements to stop before reaching inside the
feed chute.
Look out for flying debris!
Before feeding, make sure that the material is
free from stones, nails and all other materials
that are not wood, paper or plastic. Also avoid
chipping wood that are frozen solid, as they will
not self---feed well.
Do not stand in front of the feed chute when
feeding. The feed roller might jerk the wood up
or to the right.
D
Feed the wood standing on the left side of the chute.
D
When chipping wood, push the wood trunk inside the
feed chute until the knives or the feed roller touches the
wood. The chipper is self--feeding, so let go of the wood
as soon as the knives or the feed roller touches it.
D
Point the discharge downwind to prevent dust or chips
from blowing onto the operator. Point the discharge
pipe away from windows, doorways and other areas
where people or animals may be.
D
Keep the work area clean so there is nothing to trip over.
D
If you are using a hydraulic feeder, refer to separate
manual.
Do not use the chipper in
temperatures below ---5 ˚ F (---20 ˚ C).
Risk of knife damage!
IMPORTANT!
8.5.REDUCING THE POWER REQUIRED.
When using a small tractor to power the CH 140 chipper,
select a 540 rpm PTO speed. Run the tractor at full engine
speed and the PTO will turn about 600---650 rpm.
Should the tractor stall when chipping, reduce the power
demand by making the chipper cut with only one knife:
Remove one knife and attach it to the other side of the disk.
Now you will be able to chip material twice as thick.
IMPORTANT! Feed the material at half speed.
1. Disengage the PTO, cut the engine and remove the
keys.
2. Open the upper housing bolts (3/4” or 19mm wrench)
and turn the upper housing aside.
3. Lock the disk with the lock bolt, fig. 20.
4. Turn the feed chute to the side.
5. Use protective gloves when handling the knives.
6. First remove the lock nut and then the knife using a 17
mm (11/16”) socket wrench. The disk bolts are
threaded through the disk so the bolts must be turned
out.
7. Before fastening the knife on the other side, prepare
the bolts as follows: Place a spring washer on the bolt.
Screw on the lock nut and tighten it to 45 Nm (38
foot---pounds).
8. Place another spring washer on the bolt and thread
the bolt through the knife into the disk as shown in
figure 11. Tighten the bolts to 45 Nm (38
foot---pounds). IMPORTANT! To retain the balance
always use all four fastening bolts of the knife .
Interchange the cutting and
counterweight knives at times to
ensure that they are equally much
worn and sharpened, and the disk
stays in balance.

Remove the knife and attach it to the other side of
the disk. The dotted line shows the knife in its
normal cutting position.
8.6.PROCEDURES AFTER OPERATING
8.6.1.CLEARING THE CHIPPER
D
Prior to shutting down the chipper, always run a large
branch of Ø 80 to100 mm (3 to 4”) into the knives and let
the chipper cut off a few inches. By then reversing the
feed direction the knives will be cleared.
To eliminate the possibility of
jamming the chipper when starting
up again, leave a branch in the
chipper as a reminder of having
cleared the knives.
IMPORTANT!
8.6.2.TURNING THE CHIPPER OFF IN
TRACTOR USE
D
Let the tractor rpm idle before turning the PTO to
OFF--position. This is especially important on tractors
with PTO brakes, such as Ford, where you, after idling
the tractor, should slowly move the PTO control lever to
the OFF--position.
8.6.3.TURNING THE CHIPPER OFF IN
HYDRAULIC MOTOR USE
After turning the chipper off wait for
all movements to stop; the disk will
continue to rotate by flywheel
momentum after the PTO has been
disconnected.
DANGER!
Never disconnect the hydraulics
from high rpm’s. This will cause risk
of cavitation and might damage the
hydraulic motor. Check that no
sounds of cavitation emit from the
hydraulic motor.
CAUTION!
To prevent cavitation it is very
important to slowly reduce the base
machine rpm’s to idle before
disconnecting the hydraulics.
