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 blower 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 WALK BEHIND BLOWER. 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 WALK BEHIND BLOWER. Be sure your gloves fit properly and do not have loose cuffs or drawstrings.
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 blower. 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 blower. Stop the engine when another person or pet approaches.
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.
Never, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard parts on the DR walk-behind WALK
BEHIND BLOWER. 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 blowing activity. Never assume that children will remain where you last saw them.
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 WALK BEHIND BLOWER engine if children or pets enter the work area.
Before, and while moving backwards, look behind, and down for small children and pets.
Never allow children to operate the blower.
Use extra care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

WALK BEHIND BLOWER
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 before storing the DR walk-behind WALK BEHIND BLOWER in any enclosure. 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 use the Blower on it. Always take the following precautions when using this machine on slopes:
Always:
Move 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 use the Blower near drop-offs, ditches, or embankments; you could lose your footing or balance.
Never use the Blower on slopes greater than 20 degrees, or any excessively steep slopes.
Never use the Blower on wet, or slippery slopes; reduced traction could result in slipping.
Never park the Blower on a steep grade or slope.

Battery Care (electric start machines)
Proper care can extend the life of a Battery. Follow these recommendations to ensure your Battery’s best performance and long life:
Do not allow the Battery charge to get too low. If the machine is not used, charge the Battery every 4 – 6 weeks. Operate the
Engine for at least 45 minutes to maintain proper Battery charge.
Store an unused Battery in a dry area that does not freeze.
Do not charge an already charged Battery. In theory, you cannot overcharge our Battery with a trickle Charger; however, when a
Battery is fully charged and the Charger is still on, it generates heat that could be harmful to the Battery. A fully charged Battery will read 12V-13.2V with a Voltmeter.
Do not continue to crank the Engine when the Battery charge is low.
Disposing of the Battery Responsibly
The Battery is a sealed lead-acid Battery. Recycle or dispose of it in an environmentally sound way.
Do not dispose of a lead-acid Battery in a fire; the Battery may explode or leak.
Do not dispose of a lead-acid Battery in your regular, household trash. Law in most areas prohibits incinerating, disposing in a landfill, or mixing a sealed lead-acid Battery with household trash.
Charging the Battery
Operate the Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you'll need to use a trickle Charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts at no more than 2 amps.
At 1 amp, you may have to charge the Battery for as long as 48 hours.
At 2 amps, you may have to charge the Battery for as long as 24 hours.
Note: The charging system of a running engine is designed to maintain a battery’s present charge. Starting a machine that has a significantly discharged or dead Battery using the Recoil Starter or Jumper Cables will not recharge the Battery.
To connect a Battery Charger to your DR WALK BEHIND BLOWER, follow the steps listed below.
1.
Detach the two (2) Battery wires going to the Battery on your DR WALK BEHIND BLOWER.
2.
Attach the black (-) Battery Charger wire to the Battery negative (-) terminal, and attach the red (+) Battery Charger wire to the
Battery positive (+) terminal.
3.
Plug the Battery Charger into an outlet.
When you are finished charging the battery, disconnect the charger from the outlet first, then disconnect the battery charger wires from the battery. If you leave the battery charger wires connected to the battery, the battery will discharge itself back into the charger.
Recycling a Used Battery
Please dispose of used batteries responsibly, according to your local hazardous materials regulations. Never throw away used batteries in your household trash.
Please dispose of your used Batteries responsibly by recycling them. Call your local Solid Waste Management District or your local waste handler to locate the collection site nearest you. Some collection sites recycle Batteries year-round; others collect them periodically.
You can also visit the Web site of Earth 911 for more information [www.earth911.org].
For a fee, you can recycle your Batteries with the International Metals Reclamation Company. Visit them at www.inmetco.com for Battery
Recycling and contact info.
To learn more about hazardous waste recycling, visit the Web site for Battery Council International [www.batterycouncil.org] or for the
Environmental Protection Agency [www.epa.gov].

Daily Checklist for the DR WALK BEHIND BLOWER
To help maintain your DR WALK BEHIND BLOWER for optimum performance, we recommend you follow this checklist each time you use your machine.
Before performing any maintenance procedure or inspection, stop the engine, wait five minutes to allow all parts to cool.
Disconnect the spark plug wire, keeping it away from the spark plug.
[ ] Check the engine oil level.
[ ] Check Fuel Level
[ ] Check the general condition of the machine, e.g.; nuts, bolts, welds, etc.
[ ] Check and clean Engine Fins and controls of Debris.
End of Season and Storage
Before performing any maintenance procedure or inspection, stop the engine, wait five minutes to allow all parts to cool.
Disconnect the spark plug wire, keeping it away from the spark plug.
If your machine will be idle for more than 30 days, we recommend using a gas stabilizer. This will prevent sediment from gumming up the Carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the tank. Completely fill the tank with fresh, unleaded gas and add the appropriate amount of stabilizer or gasoline additive. Run the Engine for a short time to allow the additive to circulate.
Change Engine Oil.
Clean dirt and debris from the Cylinder Head Cooling Fins and Muffler area of the Engine.
Remove the Spark Plug and pour about 1 ounce of motor oil into the Cylinder hole. Replace the Plug and pull the Recoil
Starter Rope until you feel strong resistance. This will coat the piston and seat the valves to prevent moisture buildup.
Empty and clean the Debris Bag and ensure it is dry. Remember, decomposing material generates heat and could start a fire.
Clean or replace the Air Filter.
Clean the exterior of the unit to remove all dirt, grease, and any other foreign material. To prevent rust, touch up painted surfaces that have been scratched or chipped.
For Electric-Start models, store the Battery in a dry area that will not freeze. If you will not use the machine over a long period, charge the Battery every four to six weeks.
If possible, store the machine in a dry, protected place. If it is necessary to store the machine outside, cover it with a protective material (especially the Engine and Housing).
