Protecting Yourself and Those Around You

This is a high-powered machine, with moving parts operating with high energy at high speeds. Use proper clothing and safety gear when operating this machine to prevent or minimize the risk of severe injury. 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 operating this machine:

 Always wear protective goggles or safety glasses with side shields while operating this vacuum system to protect your eyes

from possible foreign objects thrown from the machine.

 Wear shoes with non-slip treads when using your DR walk-behind leaf & lawn vacuum. If you have safety shoes, we

recommend wearing them. Do not use the machine while barefoot or wearing open sandals.

 Avoid wearing loose clothing or jewelry, which can catch on the machine’s moving parts.  We recommend wearing gloves while using your DR walk-behind leaf & lawn vacuum. Be sure your gloves fit properly and do

not have loose cuffs or drawstrings.

 Always wear gloves when emptying the debris bag.  After vacuuming glass, bottles or cans, dispose of this waste properly, never in a compost pile.  We recommend changing the debris bag after vacuuming glass and other debris and before using the system to vacuum

material that may be used for compost or mulch.

 Wear long pants while operating the machine.  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 vacuum. 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 near or under any moving part while the machine is running.  Keep bystanders away from your work area at all times. To be safe, do not operate the machine near small children or pets,

and never allow children to operate the vacuum. Stop the engine when another person or pet approaches.

 Never use the machine with the debris bag removed.  Never operate the engine with the air cleaner or cover over the carburetor air-intake removed, except for adjustment. Removal

of such parts could create a fire hazard. Do not use flammable solutions to clean air filter.

 The muffler and engine become very hot and can cause a severe burn; do not touch.  Clear the work area of objects such as rock, string-like material, wire, rope, or rags. Ingesting these objects into the vacuum

could damage the machine and/or cause injury.

 Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR walk-behind leaf & lawn

vacuum. 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. Children are often attracted to the machine and the vacuuming activity. Never

 Keep children out of the work area and under the watchful care of a responsible adult.  Be alert and always turn off the DR walk-behind leaf & lawn vacuum engine if children enter the work area.  Before, and while moving backwards, look behind, and down for small children.  Never allow children to operate the vacuum.  Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

assume that children will remain where you last saw them.

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 away from heat and open

flame, and out of the reach of children.

 Fill the gasoline tank outdoors with the engine off and allow the engine to cool completely. Do not handle gasoline if you or

anyone nearby is smoking, or if you are near anything that could cause it to ignite or explode. Replace the fuel tank and fuel container caps 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 and empty the debris bag before storing the DR walk-behind leaf & lawn vacuum in any

enclosure. Remember, decomposing material generates heat and could start a fire. Never store the machine with gas in the tank or a fuel container, near an open flame or spark such as a water heater.

 Never make adjustments or repairs with the engine running. Disconnect the spark plug wire and keep the wire away from the

spark plug to prevent accidental starting.

 Never check for an ignition spark with the spark plug or spark plug wire removed. Use an approved spark tester.  Never tamper with safety devices. Check their proper operation regularly.  Never change the engine governor settings or modify the engine speed. Modifications will void your warranty.  To reduce fire hazard, keep the engine and muffler area free of debris build-up such as leaves, grass, oil, grease, or any other

combustible material. Clean the engine area after each use.

 Never operate the engine without the muffler. Inspect the muffler periodically and replace if necessary. If equipped with a

muffler deflector, inspect the deflector periodically and replace if necessary.

 Never operate the engine with the air cleaner or the cover over the carburetor air-intake removed, except for adjustment.

Removal of such parts could create a fire hazard.

 Always check fuel lines and fittings frequently for cracks or leaks, replace if necessary.

Safety on Slopes

Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All slopes require caution. If you feel uneasy on a slope, do not vacuum it. Always take the following precautions when using this machine on slopes:

Always:

 Vacuum across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes.  Remove objects such as stones, wire, rope, or rags.  Watch for holes, ruts, or bumps in the landscape.

Never:

 Never vacuum near drop-offs, ditches, or embankments; you could lose your footing or balance.  Never vacuum on slopes greater than 20 degrees, or any excessively steep slopes.  Never vacuum on wet, or slippery slopes; reduced traction could result in slipping.  Never park the vacuum on a steep grade or slope.

General Safety

Operating this vacuum safely is necessary to prevent or minimize the risk of death or serious injury. Unsafe operation can create a number of hazards for you. Always take the following precautions when operating this vacuum:

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

themselves.

 Your DR walk-behind leaf & lawn vacuum is a powerful tool, not a plaything. Exercise extreme caution at all times. The

design of this machine is to vacuum debris. Do not use it for any other purpose.

 Know how to stop the vacuum quickly.  Never allow people or pets to ride on the DR walk-behind leaf & lawn vacuum.  Never start the engine without the debris bag attached firmly to the discharge tube.  Never attempt to remove the debris bag while the DR walk-behind leaf & lawn vacuum engine is running. Debris may exit at

high velocity out of the openings created in the seams as you unlatch the debris bag.

 Empty the debris bag after each use to prevent spontaneous combustion due to decaying material.  Do not vacuum in sandy areas where you will vacuum large quantities of sand.  Never operate the vacuum near hot or burning debris or any toxic or explosive materials.  If the machine should start making an unusual noise or vibration, stop the engine and wait five (5) minutes to cool. Vibration

is generally a warning of trouble. Disconnect the spark plug wire and inspect for clogging, damaged, or worn impeller, loose impeller bolt, loose impeller key, or loose engine mounting bolts. Clean and repair and/or replace damaged parts.

 Always shut off the DR walk-behind leaf & lawn vacuum engine, wait five (5) minutes to cool, and disconnect the spark plug

wire before attempting to clear any obstructions.

 Always keep the equipment in a good safe operating condition. Always make certain nuts and bolts are tight and always use

the supplied self-locking hardware; do not substitute.

 Use the DR walk-behind leaf & lawn vacuum only in daylight.  While using the vacuum, do not 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 leave the machine unattended with the engine running.  Do not operate the machine when under the influence of alcohol, drugs, or medication.  See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by DR

Power Equipment.

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 LEAF and LAWN VACUUMS 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.

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 Mower in a safe manner. Contact us at www.DRpower.com or call 1 (800) DR-owner (376-
