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.
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 allow the engine to cool 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 machine that has gas in the tank, or a fuel
container, 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, 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.
Safety for Children and Pets
Safety with Gasoline - Powered Machines

Battery Care (For Electric-Starting Models Only)
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 environment with temperatures between +40°F (+5°C) and +95°F (+35°C). Make sure the
storage temperatures will never be outside of these limits. The lower the storage temperature is within the specified
temperature, the better as the battery will discharge more slowly at low temperatures.
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 your Engine when the Battery charge is low.
Charging the Battery
Operate the Engine for at least 45 minutes to maintain proper Battery charge. If the Battery loses its charge, you will need to use a
trickle charger (like the DR Battery Charger) to recharge it. The Charger should have an output of 12 volts DC at no more than 2
amps.
At 1 amp the Battery may need to be charged for as long as 48 hours.
At 2 amps, the Battery may need to be charged for as long as 24 hours.
NOTE: Using the Recoil Starter and then running the Engine will not recharge a dead or significantly discharged Battery.
To connect a Battery Charger to your DR LAWN EDGER, follow the steps listed below.
1. Attach the Black (-) alligator clipped wire from the Charger Adapter to the Negative (-) terminal of the Battery, then attach the
Red (+) alligator clipped wire to the Positive (+) Battery terminal.
2. Plug the Charger into a standard wall outlet.
Typically, the Battery takes between 6 and 8 hours to fully charge. Do not leave the charger on the battery longer than
24 hours for a 2 amp charger, or 48 hours for a 1 amp charger as you could potentially damage the battery..
You can charge the Battery many times. The Battery lasts longer if you charge it before it is fully drained. Keep it fully
charged and at room temperature when not using your DR LAWN EDGER.
If the Battery does not hold its charge for very long under normal conditions or it simply won’t hold a charge, then
replace it. You can purchase replacement Batteries directly from us. To install your new Battery, follow the directions
on the next page.
Disposing of the Battery Responsibly (Electric-Start Models)
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.
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.
