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.
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.

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:
A
lways:
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.
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.

Please dispose of used batteries responsibly, according to your local hazardous materials regulations. Never throw away used
batteries in your household trash.
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.
Recycling a Used Battery
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].
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.
