CHIPPER ATTACHMENT

Chapter 1: General Safety Rules

 Read this Safety & Operating Instructions manual before you use the DR CHIPPER ATTACHMENT. 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.

Labels

Your DR CHIPPER ATTACHMENT carries prominent labels as reminders for its proper and safe use. Shown below are copies of all the safety and information labels that appear on the equipment. Take a moment to study them and make a note of their location on your DR CHIPPER ATTACHMENT as you set up and before you operate the unit. Replace damaged or missing safety and information labels immediately.

Protecting 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 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 the chipper.  Use ear protectors 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 100 feet 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. Stop the chipper when another person or pet approaches.

 Disengage the blade at the control panel of the field and brush mower. Shut down the engine, wait for all moving parts to

come to a complete stop, remove spark plug wire keeping it away from the spark plug to prevent accidental starting, then wait 5 minutes before performing any maintenance or inspection on the chipper.

 Never use the machine without ensuring that all guards and shields are in place, including the chipper hopper, discharge

chute and blowback shield.

 Always operate the machine from the operator zone (see “operation notes” in chapter 4). Never pass or stand on the

discharge side of the machine when the engine is running or the flywheel is turning.

 Never try to pick up, move, or transport the machine while the blade is engaged or the flywheel is turning. Disengage the

blade at the control panel of the field and brush mower. Shut down the engine, wait for all moving parts to come to a complete stop, remove spark plug wire keeping it away from the spark plug to prevent accidental starting, then wait 5 minutes before moving.

 Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR CHIPPER

ATTACHMENT. This includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will void your warranty.

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. precautions:

 Keep children and pets at least 100 feet from the working area and ensure they are 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 the DR CHIPPER ATTACHMENT.

. Unsafe operation can create a

 Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and

themselves.

 Your DR CHIPPER ATTACHMENT is a powerful tool, not a plaything. Exercise extreme caution at all times. The design of this

machine is to chip wood. Do not use it for any other purpose.

 Know how to stop the chipper quickly; see “stopping the chipper” in chapter 4.  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.

 Never allow an accumulation of processed material to build up in the discharge area as this will prevent proper discharge and

can result in kickback from the chipper hopper.

 Whenever you leave the operating position or if you have to remove processed material, leaves, or debris from the machine,

always disengage the blade at the control panel of the field and brush mower. Shut down the engine, wait for all moving parts to come to a complete stop, remove spark plug wire keeping it away from the spark plug to prevent accidental starting, then wait 5 minutes before removing processed material, leaves, or debris from the machine.

 Always disengage the blade when moving the chipper attachment with the field and brush mower.  Keep combustible substances away from the engine when it is hot.  Never cover the machine while the muffler is still hot.  If the cutting mechanism strikes a foreign object or if your machine should start making an unusual noise or vibration,

disengage the blade at the control panel of the field and brush mower. Shut down the engine, wait for all moving parts to come to a complete stop, remove spark plug wire keeping it away from the spark plug to prevent accidental starting, 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 “using the chipper hopper” in

chapter 4. Personal injury or damage to the machine could result.

 While using the DR CHIPPER ATTACHMENT, don't hurry or take things for granted. When in doubt about the equipment or

your surroundings, stop the machine and take the time to look things over.

 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.

Additional Information and Potential Changes

No list of warnings and cautions can be all-inclusive. If situations occur that are not covered by this manual, the operator must apply common sense and operate this chipper in a safe manner. Contact us at www.DRpower.com or call 1 (800) dr-owner (376-
