Page 13 5" Chipper W/Hyd. Feed Owners Manual
If engine kills when engaging foot clutch pedal, either
use more choke or increase engine RPM. When the
clutch is engaged the foot pedal may vibrate or shake
until the engine and rotor have increased to full
operating RPM.
NOTE
1. Place tractor transmission in neutral and set parking
brake.
2 Connect 3 pt. mounts between the chipper and the
tractor. Secure connections with snap pins. Adjust 3
pt. top link so the chipper sits level.
3. Connect PTO shaft to tractor. Make sure you are
using the correct RPM machine.
4. Start tractor engine and engage PTO drive clutch
(refer to tractor owners manual). Increase speed to
rated PTO RPM position.
Note: Do not inspect or work on PTO drive area
without first disengaging PTO and shutting off tractor
engine.
1. Select limbs that are between 3/4 and 5 inches in
diameter; trim side branches off that cannot be bent
over enough to fit into the chipper chute. Some small
branches can be broken off on the chipper chute
transport handle. Small diameter branches can be
held together in a bundle and fed in simultaneously.
2. Place limb, butt end first, into the chipper chute until
it contacts the chipping blades. The actual feed rate
of the limb into the chipper will depend on the type of
material being fed, the sharpness of the cutting
blades and the size of the machine. Alternately insert
and retract the limb or insert continuously at a rate
that will not kill the engine. Rotating the branch as it
is being fed will improve cutting action.
3. The chipping blades will dull with use and require
periodic sharpening. Approximate sharpening time is
every 10 hours, or every rental if used commercially.
Refer to the Service and Maintenance section for
instructions.
4.3 CHIPPING
Due to the aggressiveness of the machines chipping
capacity, do not attempt to hold on to material
intended for chipping once it has been placed in the
chute.
WARNING

4.1 STARTING (TOWABLE MODEL)
Move machine to a clear, level area outdoors before starting.
Do not operate machine on a paved, concrete, or gravel
surface. Do not operate in the vicinity of bystanders. Make
sure cutting chamber is empty before starting.
1. Before starting, check engine oil level and fill if neces-
sary. See engine owners manual for operation and main-
tenance instructions.
2. Before starting, fill fuel tank with fresh, clean unleaded
regular gasoline. DO NOT MIX OIL WITH GASOLINE.
3. Disengage clutch lever by pressing foot clutch pedal.
4. Place engine throttle lever at 3/4 - full open position.
Place engine choke lever to choke position.
5. Activate the starter switch. Release the key as soon
as the engine starts. Do not crank for more than 10
seconds. Repeat if necessary.
6. Move choke lever to run position after engine starts.
Some choke may be needed until engine is fully
