SAFETY GUIDELINES
**SAVE THESE INSTRUCTIONS**
•Do not operate this machine until this manual has been read and fully understood; serious
injury or severe machine damage could occur if these safety warnings are ignored.
•Never allow more than one person to operate this machine at one time. If two people are
working together it will increase the chance of your workmate engaging the machine or
causing you to fall into the machine.
•If your hand is ever near the chipping or feeding area, serious injury could occur.
•Never place your hands or feet on or near the machine while it is engaged.
•Never place your hands or feet on or near the material while it is feeding.
•DO NOT wear loose clothing, jewelry, or anything that can catch a branch that is feeding into
the wood chipper.
•DO NOT stand directly in front of the infeed chute when loading material into the hopper;
always load from the side of the hopper. This will help prevent any part of your body from
being pulled into the machine.
•Always wear safety hearing protection, eye wear, gloves, and long pants when operating the
wood chipper.
•Never place your hands beyond the opening of the hopper while the wood chipper is running.
•Never allow children, disabled, or untrained persons to operate the wood chipper.
•Do not operate the wood chipper near bystanders, public roads, or anywhere that debris may
travel far enough to injure another person.
•Never move the wood chipper while it is running.
•Shut off the tractor and allow the wood chipper to come to a complete stop before removing
any debris.
•Never perform any maintenance or repair while the wood chipper is running.

ROTATING DRIVELINES
**STAY CLEAR OF ROTATING DRIVELINES**
•Entanglement in rotating driveline can cause serious injury or death.
•Keep tractor master shield and driveline shields in place at all times. Make sure rotating
shields spin freely.
•Wear close-fitting clothing.
•Shut off the engine and be sure the PTO driveline has stopped before making adjustments,
connections, or cleaning out PTO-driven equipment.
•Do not install any adapter device between the tractor and the primary implement PTO drive
shaft that would allow a 1000 RPM tractor shaft to power a 540 RPM implement at speeds
higher than 540 RPM.
•Do not install any adapter device that results in a portion of the rotating implement shaft,
tractor shaft, or the adapter to be unguarded. The tractor master shield shall overlap the end
of the splined shaft.

The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions or situations that could
occur. It must be understood by the operator that common sense and
caution are factors which cannot be built into this product but must be
supplied by the operator.
WARNING!
Read and understand all instructions. Failure to properly follow the
instructions listed below may result in serious injury or death.
WARNING!

PERSONAL SAFETY
•Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool when you are tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
•Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be
caught in moving parts. Air vents often cover moving parts and should be avoided.
•Use safety apparel and equipment. Use safety goggles or safety glasses with side shields
that comply with current national standards, or when needed, a face shield. Use a dust mask
in dusty work conditions. This applies to all persons in the work area. Also use non-skid
safety shoes, a hardhat, gloves, dust collection systems, and hearing protection when
appropriate.
•Do not over reach. Keep proper footing and balance at all times.
•Remove adjusting keys or wrenches before connecting to the power supply or turning on
the tool. A wrench or key that is left attached to a rotating part of the tool may result in
personal injury.
•Never remove or install blades, conduct any maintenance, or make any other
adjustments while the tractor engine is running. Always shut the engine off, remove the
ignition key, and disconnect the PTO shaft prior to carrying out any of the aforementioned
procedures. Consult your tractor’s manual for safe shutdown procedures to prevent
accidental ignition.

WORK AREA
•Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause
accidents.
•Do not use your wood chipper where there is a risk of causing a fire or an explosion;
e.g. in the presence of flammable liquids, gasses, or dust. Power tools create sparks which
may ignite the dust or fumes.
•Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control, therefore, visitors should remain a safe distance from the work area.
•Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards
in your work area, particularly those hazards below the work surface hidden from the
operator’s view that may be unintentionally contacted and cause personal harm or property
damage.
•Be aware of your surroundings. Using power tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.

TOOL USE AND CARE
•Always be sure the operator is familiar with proper safety precautions and operation
techniques before using machine.
•Do not force the tool. Tools do a better and safer job when used in the manner for which
they are designed.
•Turn off the tractor engine and disconnect the PTO shaft before servicing, adjusting,
installing accessories or attachments, or storing. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
•Storing the wood chipper. When the wood chipper is not in use, store it in a dry, secure
place or keep it well covered and out of reach of children. Inspect the wood chipper for good
working condition prior to storage and before re-use.
•Maintain your wood chipper. It is recommended that the general condition of the wood
chipper be examined before it is used. Keep your wood chipper in good repair by adopting a
program of conscientious repair and maintenance in accordance with the recommended
procedures found in this manual. If abnormal vibration or noise occurs, turn the wood chipper
off immediately and have the problem corrected before further use.
•Keep blades sharp and clean. Properly maintained wood chipper blades are less likely to
bind and make feeding-in brush easier.
•Cleaning and Lubrication. Use only soap and a damp cloth to clean your wood chipper.
Many household cleaners are harmful to plastic and rubber components on the wood chipper.
•Use only accessories that are recommended by the manufacturer for your model.
Suitable accessories for another wood chipper may create an injury risk when used on this
wood chipper.
•Always operate the machine with all safety devices and guards in place and in working order.
DO NOT modify or make changes to safety devices. DO NOT operate the machine if any
safety devices or guards are missing or inoperative.
•Never leave wood chipper running unattended.
•Never use the equipment to chip brush with trunks exceeding 6” (152 mm) in diameter
or for any purpose other than chipping brush as described in this manual.

2. UNPACKING
A. UNBOXING THE CRATE
Unpack the contents of the crate by first cutting the nylon strapping and then remove the cardboard
top and sides. Use a 13 mm socket/wrench to remove the four (4) M8 hex bolts and nuts located at
each bottom corner of the crate and then lift it off the skid. Discard the crate.
Remove all the loose components from the skid (infeed chute panels, control arm, edge bar, control
arm linkage, discharge chute, PTO shaft, hardware boxes) and set them to the side. Use the
tractor’s 3-point hitch system to lift the wood chipper off the skid and set it on the ground. Discard
the skid.

using the M8 X 16 mm button head screws, M8 lock nuts, and M8 fender washers. Use an M6
hex key for the screws and a 13 mm socket/wrench for the lock nuts.
Install two (2) screws per side along the top edge leaving the last holes empty. Do not fully
tighten the screws. Be sure to assemble the screws with the heads on the inside of the chute
pointing outwards. Next, install the bottom panel using only the first two (2) bolts as shown
below (right). This will allow it to swing up to join the side panels in the coming steps. Note that
the infeed chute bottom panel and latches come pre-assembled from the factory.
