Always wear protective goggles or safety glasses with side shields while using the DR LAWN AERATOR to protect your eyes
from possible thrown debris.
Avoid wearing loose clothing or jewelry, which can catch on moving parts.
We recommend wearing gloves while using the DR LAWN AERATOR. Be sure your gloves fit properly and do not have loose
cuffs or drawstrings.
Wear shoes with non-slip treads when using your DR LAWN AERATOR. If you have safety shoes, we recommend wearing

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 aerating activity.
precautions:
Never
assume that children will remain where you last saw them. Always follow these
Keep children and pets at least 50 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 LAWN AERATOR.
Safety with Gasoline - Powered Machines
Gasoline is a highly flammable liquid. Gasoline also gives off flammable vapor that can be easily ignited and cause a fire or
explosion. Never overlook the hazards of gasoline. Always follow these precautions:
Never run the engine in an enclosed area or without proper ventilation as the exhaust from the engine contains carbon
monoxide, which is an odorless, tasteless, and deadly poisonous gas.
Store all fuel and oil in containers specifically designed and approved for this purpose and keep them away from heat and
open flame, and out of the reach of children.
Replace rubber fuel lines and grommets when worn or damaged and after 5 years of use.
Fill the gasoline tank outdoors with the engine off and after the engine has cooled completely. Don't handle gasoline if you or
anyone nearby is smoking, or if you're near anything that could cause it to ignite or explode. Reinstall the fuel tank cap and
fuel container cap securely.
If you spill gasoline, do not attempt to start the engine. Move the machine away from the area of the spill and avoid creating
any source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to prevent a fire hazard and properly
dispose of the waste.
Allow the engine to cool completely before storing in any enclosure. Never store a fuel container or machine that has gas in
the tank near an open flame or spark such as a water heater, space heater, clothes dryer or furnace.
Never make adjustments or repairs with the engine running. Shut down the engine, disconnect the spark plug wire, keeping it
away from the spark plug to prevent accidental starting and wait 5 minutes before making adjustments or repairs.
Never tamper with the engine’s governor setting. The governor controls the maximum safe operation speed and protects the
engine. Over-speeding the engine is dangerous and will cause damage to the engine and to the other moving parts of the
machine. If required, see your authorized dealer for engine governor adjustments.
Keep combustible substances away from the engine when it is hot.
Never cover the machine while the muffler is still hot.
Do not operate the engine with the air cleaner or the carburetor air intake cover removed. Removal of such parts could create
a fire hazard. Do not use flammable solutions to clean the air filter.
The muffler and engine become very hot and can cause a severe burn; do not touch.
Protecting Yourself and those around you
Operating the DR LAWN AERATOR safely is necessary to prevent or minimize the risk of death or serious injury. 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 operating the DR LAWN AERATOR:
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people, their property, and
themselves.
Your DR LAWN AERATOR is a powerful tool, not a plaything. Exercise extreme caution at all times. The machine is designed
to aerate lawns. Do not use it for any other purpose.

Protecting Yourself and those around you (continued)
Keep bystanders at least 50 feet away from your work area at all times. Stop the engine when another person or pet
approaches.
Know how to stop the DR LAWN AERATOR quickly; see “stopping the engine” in chapter 3.
Never operate your unit on a slippery, wet, muddy, or icy surface. Exercise caution to avoid slipping or falling.
Never use the machine without ensuring that all guards and shields are in place.
Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the LAWN AERATOR. This
includes all shields and guards. Modifications to your machine could cause personal injuries and property damage and will
void your warranty.
Allow only one person to operate the DR LAWN AERATOR at any time.
If the machine should start making an unusual noise or vibration, shut down the engine, disconnect the spark plug wire,
keeping it away from the spark plug to prevent accidental starting, wait 5 minutes, then inspect for loose parts or damage.
Vibration is generally a warning of trouble. Tighten, clean, repair and/or replace parts as necessary.
Never tamper with safety devices. Check their proper operation regularly.
Before performing any maintenance or inspection procedure on the DR LAWN AERATOR, raise the tines with the tine
position lever first and then release the bail bar to disengage tines, move throttle to idle, switch the engine off, remove the
spark plug wire and keep it away from the spark plug.
Never allow people who are unfamiliar with these instructions to use the DR LAWN AERATOR. Allow only responsible
individuals who are familiar with these rules of safe operation to use your machine. Disconnect the spark plug wire when the
machine is not being used to prevent operation without instruction.
Never overload or attempt to aerate lawns beyond the manufacturer’s recommendation. Personal injury or damage to the
machine could result.
While using the DR LAWN AERATOR, 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.
Stay alert for hidden hazards or traffic.
Keep all nuts and bolts tight and keep the equipment in good operating condition.
Never cross hard objects or surfaces (sidewalks, driveways, stepping stones, etc.) with the aerating tines down.
Do not use this machine on hills greater than 15 degrees, especially when turning.
Keep hands and feet away from operating parts.
Never leave the machine unattended while running.
A Note to All Users
Under California law, and the laws of some other states, you are not permitted to operate an internal combustion engine using
hydrocarbon fuels without an engine spark arrester. This also applies to operation on US Forest Lands. All DR
AERATORS shipped to California, New Mexico and Washington State are provided with spark arresters. Failure of the owner or
operator to maintain this equipment in compliance with state regulations is a misdemeanor under California law and may be in
violation of other state and/or federal regulations. Contact your State Park Association or the appropriate state organization for
specific information in your area.
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 DR LAWN AERATOR in a safe manner. Contact us at www.DRpower.com or call 1-800-DROWNER (376-9637) for assistance.
