TOWING INSTRUCTIONS
While towing the 3107C obey all traffic laws and never exceed 45mph (75km/h). The towing vehicle
and the 3107C must be in legal, road worthy condition which may include registration. Refer to and
check the following list before towing.
NOTICE: Move the fuel shutoff lever to the closed position after stopping the engine, especially
before towing. Failure to do so could cause fuel to leak into the cylinder and crankcase.
Resulting damage will not be covered under warranty.
•Inspect all towing points: hitch/coupler; hitch ball; safety chains and safety chain attachment
points on towing vehicle and 3107C tongue. Replace any damaged components before towing.
•Inspect 3107C tires for damage and check tire pressure. See tire side wall for correct tire pressure.
•The towing vehicle must be rated to tow trailers in excess of 1500 pounds with a tongue weight in
excess of 180 pounds.
•The towing vehicle must be equipped with a 2” hitch ball. The hitch ball must be in good
condition and be securely fastened to the towing vehicle.
•The towing vehicle must have 2 points, one on either side of the hitch ball to attach the safety
chain.
•The safety chain must be securely fastened to the 3107C tongue.
•If equipped with lights, connect the wiring adapter on the 3107C to the plug on the towing vehicle.
Make sure that all lights, on both vehicles work. If NOT equipped with lights do not tow at night
or other low light conditions.
•Securely fasten the coupler to the hitch ball by tightening the coupler nut.
•Cross the safety chains under the tongue and secure them to the towing vehicle in such a way as to
prevent accidentally coming off. Crossing the safety chain helps prevent the tongue from
dropping to the ground should the hitch come off.
•DO NOT LET THE CHAINS TOUCH THE GROUND OR BE DRAWN TOO TIGHT. Allow
only enough slack to permit proper turning of the towing vehicle. Slack in the safety chain should
be reduced until the tongue cannot hit the ground should the coupler come loose.
•The swivel jack or stand must be parallel with the tongue and pinned in place.
•The rear flap must be locked in the upright position.
•After towing for a few blocks stop and check that all connection points are securely connected.
•While towing exercise extreme caution, allow extra space between vehicles and expect longer
stopping distance.
•Local laws vary. It is your responsibility to know and obey all laws on the road.

NOTICE: Failure close the fuel shut-off valve may damage the engine and void the engine warranty.
ENGAGING THE CLUTCH
Engaging the centrifugal clutch:
1. With engine running, slowly increase throttle until centrifugal clutch is engaged
2. Continue increasing throttle until at full Engine and Flywheel RPM.
FEEDING MATERIAL
To prevent the 3107C from clogging:
•DO allow the chipper a moment to get back up to speed between feeding cycles.
•DO run the engine at full throttle.
•DO NOT feed material that is too large for the 3107C into the feed chute
Feeding the chipper:
Push the feed wheel handle towards the machine to start the feed wheel hydraulic motor. Feed the
chipper hopper with tree limbs and branches up to 7 inches thick. Feed large leafy branches so that
the leaves will be the last part in the chipper.
The automatic feed system will slow or stop the feed wheel if the Flywheel slows down to a pre-set
RPM. Allow the Flywheel and Engine to return to full RPM before feeding additional material.
NOTICE: ONLY PUT WOOD AND PLANT MATERIALS IN THE 3107C, OTHER
MATERIALS WILL DAMAGE THE MACHINE.
