Battery Care (For Electric-Starting Models)

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 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 at no more than 2 amps.

• At 1 amp, the Battery may need charging for as long as 48 hours.

• At 2 amps, the Battery may need charging 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 WALK-BEHIND LEAF & LAWN VACUUM, follow the steps listed below.

1. Detach the two (2) Battery cables going to the Battery on your machine.

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.

End of Season and Storage

• WHEN PERFORMING ANY MAINTENANCE, YOU MUST FIRST SHUT OFF THE ENGINE, WAIT FIVE

(5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG.

• EMPTY THE DEBRIS BAG TO PREVENT SPONTANEOUS COMBUSTION DUE TO DECAYING MATERIAL.

NOTE: Please refer to the Engine Owner’s Manual for Engine-specific procedures.

• Change the oil.

• If your DR WALK-BEHIND LEAF & LAWN VACUUM 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.

• 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.

• Clean or replace the Air Filter.

• Clean dirt and debris from the Cylinder Head Cooling Fins, Impeller Housing, Debris Screen, and

Muffler area of the Engine.

• Clean out residual debris from the Nozzle.

• Clean the Debris Bag. See page 24.

• 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. See page 32.

Troubleshooting Table

WHEN PERFORMING ANY MAINTENANCE, YOU MUST FIRST SHUT OFF THE ENGINE, WAIT FIVE (5) MINUTES TO ALLOW PARTS TO COOL AND DISCONNECT THE SPARK PLUG WIRE, KEEPING IT AWAY FROM THE SPARK PLUG.

SYMPTOM POSSIBLE CAUSE

Recoil will not pull out or is difficult to pull.

⇒ Check for debris in the Impeller Housing.

⇒ Check the Engine oil level; the Engine may be seized.

⇒ There may be an oil compression lock in the cylinder. Take out the Spark Plug;

hold a rag over the Spark Plug hole and pull the Recoil Cord several times to blow out any oil in the cylinder. Wipe off the Spark Plug and reinstall it.

The Engine will not start manually.

(Please refer to the Engine Owner’s Manual for Enginespecific procedures.)

⇒ The Recoil may be broken or jammed. Call 1-800-DR-OWNER (376-9637) for

assistance.

⇒ Check that the Spark Plug Wire is attached.

⇒ Check that the Bag is properly installed, latched, and the Bag Presence Interlock

Switch is depressed. See page 18 Figure 14c. Also, check that the Bag frame rod is not bent.

⇒ Check the oil and gas level. See page 15.

⇒ The gas may be old, change it. Use a fuel stabilizer if you keep gas longer than

one month.

⇒ Check the Throttle adjustment and travel. See page 39. ⇒ The Spark Plug may be dirty or cracked, change it. If it’s oily, leave it out, hold a

rag over the Plug hole and pull the Recoil Cord several times to blow out any oil in the Cylinder, then wipe off the Plug and reinsert it.

SYMPTOM POSSIBLE CAUSE

The Engine will not start using ElectricStart.

(Please refer to the Engine Owner’s Manual for Enginespecific procedures.)

⇒ Check all the items under the section called Electric-Starting on page 19. ⇒ Check the previous section (Manual Starting) for possible causes. ⇒ Check the wire connections—especially the ground connection, the large black

wire coming from the Battery, where it connects to the Engine.

⇒ Check the wire connections to the Solenoid. Disconnect the black Battery ground

wire first to avoid sparks. Check to be sure that all of the connections are clean and tight. Reconnect the Battery ground wire.

⇒ Check the ground connection on the Solenoid where it is bolted to the Frame.

Using a wrench or socket, tighten the bolts to ensure a good connection to the Frame.

⇒ The Battery may not be charged. Check the voltage yourself or at a gas station. If

it is low, charge it with a 12-volt, 1 to 2 Amp trickle charger. If you do not use your vacuum for at least 45 minutes at a time, the Battery may need to be periodically charged. See the Battery Care section on page 32.

⇒ If your Battery is charged and your DR WALK-BEHIND LEAF & LAWN VACUUM

still will not start, call 1-800-DR-OWNER (376-9637) for assistance.

Engine smokes.

⇒ Check the Throttle to make sure it is set in the FAST position. ⇒ The Air Filter may be dirty, change it following the procedure in the Engine

Owner’s Manual.

⇒ The Spark Plug may be dirty or cracked, change it. If it’s oily, leave it out, hold a

rag over the Plug hole and pull the Recoil Cord several times to blow out any oil in the Cylinder, then wipe off the Plug and reinsert it.

⇒ The gas may be old, change it. Use a fuel stabilizer if you keep gas longer than

one month.

⇒ The Engine may not have the right amount of clean oil. If it is dirty, change it

following the procedure on page 31.

⇒ If your Engine still lacks power, call 1-800-DR-OWNER (376-9637) for assistance.

⇒ Check the oil level and adjust as needed. ⇒ You may be operating the machine on too great an incline. See page 23. ⇒ Check the Air Filter and clean or replace if needed. ⇒ You may be using the wrong oil—too light for the temperature. Refer to your

Engine Owner’s Manual for detailed information.

⇒ Clean the Engine Cooling Fins and the Carburetor Housing if they are dirty. ⇒ If the Engine still smokes, call 1-800-DR-OWNER (376-9637) for assistance.

Fill the reservoir according to the dipstick with SAE 30 HD motor oil. See page 15.

[ ] GAS: Fill the gas tank with fresh, unleaded gasoline. See page 15.

[ ] ENGINE: It is very important to keep the engine clean. Remove dirt and other debris from the

engine cooling fins and debris guard. A dirty engine retains heat and can cause damage to internal engine components.

[ ] HARDWARE: Check all nuts and bolts to be sure that the components are secure.

[ ] FRAME: Check all welds to be sure that the frame is intact and secure.

[ ] DEBRIS BAG: Make sure that the Debris Bag is securely fastened to the Top Shield Assembly and

the Bag Presence Interlock Switch is engaged. See page 25.

[ ] NOZZLE and IMPELLER: Make sure that the Nozzle and Impeller are free of accumulated debris
