2 . General safety rules
• Read this safety & operating manual and your tractor owner's manual before you use PTO
chipper. Become familiar with the operation and service recommendations to ensure the best
performance from your machine.
• Thoroughly inspect the area in which you will be working and remove all foreign objects.
Look for rope, wire, etc., and remove these objects before chipping. Inserting these objects
into the chipper hopper could damage the machine and/or cause injury.
• This is a high-powered machine, with moving parts operating with high energy at high
speeds. You must use proper clothing and safety gear when operating this machine to
prevent or minimize the risk of severe injury. This machine can crush, grind, cut, and sever
parts of your body if they enter the inlet or discharge area of your chipper.
2.1 Labels
Your PTO CHIPPER carries prominent labels as reminders for its proper and safe use.
Shown below are copies of all the safety and operation labels that appear on the equipment.
Take a moment to study them and make a note of their location on your chipper as you
assemble and before you operate the unit. Replace damaged or missing safety and operation
labels immediately.

2.2 Safety for Yourself and Those Around You
• This is a high-powered machine, with moving parts operating with high energy at high
speeds. You must operate the machine safely.
• Unsafe operation can create a number of hazards for you, as well as anyone else in the
nearby area.
ALWAYS TAKE THE FOLLOWING PRECAUTIONS WHEN USING THIS MACHINE:
• Always wear protective goggles or safety glasses with side shields while chipping to

4
protect your eyes from possible thrown debris.
• Avoid wearing loose clothing or jewelry, which can catch on moving parts or the material
fed into the chipper hopper.
• We recommend wearing gloves while chipping. Be sure your gloves fit properly and do not
have loose cuffs or drawstrings.
• Wear shoes with non-slip treads when using your chipper. If you have safety shoes, we
recommend wearing them. Do not use the machine while barefoot or wearing open sandals.
• Wear long pants while operating PTO chipper.
• Use mufflers or ear plugs rated for at least 20 dba to protect your hearing.
• Never allow people who are unfamiliar with these instructions to use the chipper. Allow
only responsible individuals who are familiar with these rules of safe operation to use your
machine.
• Never place your hands, feet, or any part of your body in the chipper hopper, discharge
opening, or near or under any moving part while the machine is running. Keep area of
discharge clear of people, animals, buildings, glass, or anything else that will obstruct clear
discharge, cause injury, or damage. Wind can also change discharge direction, so be aware.
If it becomes necessary to push material into the chipper hopper, use a small diameter stick,
not your hands.
• Keep bystanders 10 meters away from your work area at all times. Wood chips exit the
chipper at great speeds. To be safe, do not operate the machine near small children or pets,
and never allow children to operate the chipper. Disengage the PTO and stop the tractor
engine when another person or pet approaches.
• Never use the machine without ensuring that all guards and shields are in place, including
the chipper hopper, conveyor and blowback shield.

5
• Always operate the machine from the operator zone. Never pass or stand on the discharge
side of the machine when the tractor engine is running or the rotor is turning.
•Never transport the chipper with the PTO engaged and the rotor turning.
• Clear the area of objects such as wire and rope, etc. Inserting these objects into the chipper
hopper could damage the rotor and/or cause injury.
• Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts
on PTO chipper. Modifications to your machine could cause personal injuries and property
damage and will void your warranty.
2.3 Safety for Children and Pets
• Tragic accidents can occur if the operator is not alert to the presence of children and pets.
Children are often attracted to the machine and the chipping activity. Never assume that
children will remain where you last saw them.
ALWAYS FOLLOW THESE PRECAUTIONS:
• Keep children and pets at least 100 feet from the working area and under the watchful care
of a responsible adult.
• be alert and turn the machine off if children or pets enter the work area.
• never allow children to operate PTO chipper.
2.4 General Safety
• PTO chipper is a powerful tool, not a plaything.
• Operating this chipper safely is necessary to prevent or minimize the risk of death or

6
serious injury. Unsafe operation can create a number of hazards for you.
• Exercise extreme caution at all times. The design of this machine is to chip wood. Do not
use it for any other purpose.
ALWAYS TAKE THE FOLLOWING PRECAUTIONS WHEN OPERATING THIS
CHIPPER:
• This machine is designed to operate at 540 rpm only! Never operate the machine at a faster
speed; doing so can cause serious injury to the operator or bystanders and could cause
damage to the machine that is not covered under warranty.
• The PTO chipper must be operated with the weight of the machine on the ground.
Operating the machine while it is off the ground can result in injury to yourself or others, or
can cause damage to the machine which is not covered under warranty.
• Keep in mind that the operator or user is responsible for accidents or hazards occurring to
other people, their property, and themselves.
• know how to stop the chipper quickly by disengaging the PTO and shutting down the
tractor.
• Operate this machine on a level surface only. Never operate your unit on a slippery, wet,
muddy, or icy surface. Exercise caution to avoid slipping or falling.
• Keep your face and body back from the chipper hopper to avoid accidental bounce back of
any material.
• When feeding material into the chipper hopper, be extremely careful that pieces of metal,
rocks, or other foreign objects are not included. Personal injury or damage to the machine
could result.
• Whenever you leave the operating position or if you have to remove processed material,

7
leaves, or debris from the machine, always disengage the PTO, shut down the tractor engine,
remove the key, wait for all moving parts to come to a complete stop, disconnect the PTO
shaft from the tractor, then wait 5 minutes before removing processed material, leaves, or
debris from the machine.
• If the cutting mechanism strikes a foreign object or if your machine should start making an
unusual noise or vibration, immediately disengage the PTO, shut down the tractor engine,
remove the key, wait for all moving parts to come to a complete stop, disconnect the PTO
shaft from the tractor, then wait 5 minutes before inspecting for clogging or damage.
Vibration is generally a Warning of trouble. Clean and repair and/or replace damaged parts.
• Never tamper with safety devices. Check their proper operation regularly.
• Stay alert for hidden hazards or traffic. Never carry passengers on your machine.
• Never overload or attempt to chip material beyond the manufacturer’s recommendation;
see chapter 4. personal injury or damage to the machine could result.

• Never operate the machine when under the influence of alcohol, drugs, or medication.
• Use the machine only in daylight.
• Keep all nuts and bolts tight and keep the equipment in good operating condition.
• Your PTO chipper is driven by a PTO shaft that transfers power from your tractor. A PTO
shaft is extremely dangerous and can cause serious injury or death. Read and understand all
of the safety and operating instructions manual that came with your PTO shaft.
