OPERATING
Use the tiller/cultivator for breaking sod, preparing seed beds, and for cultivating gardens and flower beds. The tiller/cultivator can also dig small holes for
planting saplings or potted plants.
For breaking sod or deep tilling, allow the tines to pull
the tiller/cultivator forward to the end of your arm’s reach, then firmly pull it back toward yourself. You will achieve the best results by repeatedly allowing it to
move forward and pulling it back.
By pulling the tiller/cultivator back towards yourself,
the tines will dig deeper and more aggressively.
To prevent tripping, take extra precautions when
moving backwards and when pulling the tiller/
cultivator back toward yourself.
If the tiller/cultivator digs deep enough to stay in one spot, gently rock it side to side until it starts moving
forward again.
When working on inclines always stand diagonally to the incline to retain a firm, safe footing. Do not work
on extremely steep slopes.
For preparing seed beds, we recommend using one of
these tilling patterns: (Fig. 9)
Tilling Pattern A– Make two passes over area to be
tilled, the second at a right angle to the first.
Tilling Pattern B - Make two passes over area to be tilled, the second overlapping the first.
Before use, remove any visible stones or other
foreign bodies from the area.
CAUTION: Before moving the ti ller/cult ivator from
one area to another, release the bail wire and wait for the tines to come to a complete stop. Be careful not to let the tines touch the ground while moving the tiller/cultivator. The tines as well as the unit itself may
be damaged even if the motor is switched off.
Clearing foreign objects:
During operation a stone or root could become lodged in the tines, or tall grass or weeds may become wrapped around the tine shaft. To clear the tines or tine shaft release the bail wire, wait for the tines to come to a complete stop and remove the battery. Dislodge or remove the foreign matter from the tines or tine shaft. To simplify removal of tall grass or weeds from the tine shaft, remove one or
more of the tines. See Tine Removal and Installation.

MAINTENANCE
Before each use check the condition of the
tines and ensure that all threaded connections are
securely tightened. If the tines become dull or
blunt, sharpen or replace them. Call our customer
service help line at 1-800-313-5111 for assistance.
Once per season lubricate the tines and shaft. At the end of the season, check the tiller/cultivator for damage prior to storing. Repair or replace
damaged or broken parts.
CAUTION: Always clean the tiller/cultivator after each use. Failure to carry out proper cleaning can result in damage to the tiller/cultivator or result
in poor performance.
Clean the underside of the protective shield around the tines with a scrub brush, and a soft cloth dampened with a mild soap and water mixture. Never use a water hose to clean the tiller! To remove soil and debris from the transmission and tines, use a stiff brush or a dampened cloth. Clean the vents on the motor housing and remove any remaining grass or dirt. Once cleaned, wipe the tines and shaft with a dry cloth and apply a
light coat of oil to prevent rust.
Tines maintenance: Worn tines invite poor
performance and overload of the motor. Check tines before each use. Sharpen or replace the tine assemblies with new ones when necessary. Call
1-800-313-5111 for assistance.
WARNING: Injury can occur while working on
the tines. Wear protective gloves. Tine Removal and Installation (Fig . 10)
Lift the Lock Pin rings and remove the Lock Pins at both ends of the shaft. Remove Tine A and D from the shaft. Remove the M8x40 bolts and M8 Hex lock nuts at both ends of the shaft. Remove Tine B and C from the shaft. Reverse above steps to
install Tines.
Replace worn or damaged parts with original replacement parts only. Parts from another tiller/
cultivator will not fit properly causing an unsafe
situation.
Make sure all protective devices are secure and in
good condition. Repair or replace if necessary.
Lubrication (Fig. 11): The tines drive transmission case has grease installed at the factory. It is not required that the grease level be checked nor recommended that grease be added during the first 2 years of use. After the second season of
use, follow the directions as described below:
Drain screw plug is located on the right side of transmission housing. Lay the tiller/cultivator on its left side and clean the transmission of dirt and debris prior to removing the drain screw plug. If necessary, remove tine assemblies to have better access to the drain screw plug. Use a 5mm hex
key to unscrew the plug.
Using a squeeze bottle or tube, add approximately
2.0 oz. (60ml) of auto gear lube. Do not overfill. When completed, reinstall the drain screw plug into
the transmission.

BATTERY METER
Since the tiller battery is shipped in a low charge condition, the battery must be charged before use. The battery has 3 LED lights to indicate battery capacity. These lights will only illuminate when the light indicator
button is pushed.
If three GREEN lights illuminate, the battery is charged
and ready for use. Two green lights are equal to 25%­80% charge, while one green light is equal to 5%-25% charge.
It is recommended to charge battery pack when one light
is illuminated.
CHARGING THE BATTERY PACK
The tiller comes with maintenance free, sealed 40 volt
storage batteries.
Remove the switch key from the tiller and store in a
safe location out of the reach of children.
Charge the battery pack only with the charger
provided.
Allow at least two hours of charge time before initial
use of the tiller.
Make sure the power supply is normal household
voltage, 120 volts, 60Hz, AC only.
The battery should be charged in a cool, dry place.
To improve battery life, store battery indoors in a
controlled climate. Fully charge battery pack every 3
months.
Since the battery will not develop a memory, it does
not have to be fully discharged before recharging.
2 to 3 initial charging/discharging cycles may be
required to achieve maximum run time/capacity.
When fully charged, the battery can be safely stored
in temperatures down to -4˚F(-20˚C) for a period of
up to one month before requiring charging. Fully
charge battery pack every 3 months.
The battery charger should be operated in
temperatures between 0˚F and 113˚F(-18˚C and
45˚C).
TO CHARGE
Insert the 120 volt plug of the charger into the wall receptacle. Light A will illuminate and stay green.
(Fig. 12)
Place the battery pack into the charger by sliding
the pack as shown in Fig. 13 to lock it into position. Light B will illuminate red to indicate that the battery is charging and the three lights on the battery pack
will cycle in green.
When the battery pack is fully charged, light B will
turn green and the lights on the battery pack will shut
off. (Fig 13)
NOTE: Typical time required to reach a full charge is
2 1/2 hours.
NOTE: If light A remains green while light B alternately flashes red and green, this indicates a temperature abnormality (i.e. that the battery pack is either too hot or too cold). If there is only a red blinking
light, this indicates that something is wrong with the
battery. Contact Earthwise customer service center at
1-800-313-5111 for assistance.
