TOOL)
WARNING Read all safety
warnings and all instructions. Failure to
follow the warnings and instructions
may result in electric shock, re and/or
serious injury.
Save all warnings and instructions for future
reference. The term “power tool” in the
warnings refers to your batteryoperated
(cordless) power tool.
• Use Right Appliance – Do not use
appliance for any job except that for which
it is intended.
• Read the operator’s manual carefully. Be
thoroughly familiar with the controls and
the proper use of the equipment. Know
how to stop the unit and disengage the
controls quickly.
• Do not operate the machine in explosive
atmospheres, such as in the presence
of fammable liquids, gases, or dust. The
machine creates sparks which may ignite
the dust or fumes.
• Avoid body contact with grounded surfaces
such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
• Avoid Dangerous Environment — Don’t
expose to rain or use machine in damp or
wet locations. Water entering the machine
will increase the risk of electric shock.
• Never allow children to operate the
equipment. Never allow adults to operate
the equipment without proper instruction.
• Always wear safety glasses with side
shields that comply with ANSI Z87 .1-
Everyday glasses have only impact
resistant lenses. They are NOT safety
glasses. Following this rule will reduce
the risk of eye injury. Use a face mask if

• Dress Properly – Do not wear loose
clothing or jewelry. They can be caught in
moving parts. Use of rubber gloves and
substantial footwear is recommended
when working outdoors. Wear protective
hair covering to contain long hair.
• Do not force the machine — Use the
correct tool for your application. The

• Do not overreach — Keep rm footing and
balance at all times. Overreaching can
results in loss of balance.
• Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to battery pack, picking up
or carrying the appliance. Carrying the
appliance with your nge on the switch or
energizing appliance that have the switch
on invites accidents.
• Avoid Unintentional Starting – Don’t carry
cordless machine with nger on switch. Be
sure the switch is off when inserting the
battery.
• Never pick up or carry the machine
while the tines are turning or the motor is
running.
• Keep the machine in good working
condition. Check all nuts, bolts, and screws
at frequent intervals for proper tightness to
be sure the equipment is in safe working
condition.
• Keep the machine free of grass, leaves
or grease to reduce the chance of a fire
hazard.
• Do not use the machine if switch does not
turn it on or off. Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
• Disconnect the battery pack from
the appliance before making any
adjustments, changing accessories, or
storing appliance. Such preventive safety
measures reduce the risk of starting the
appliance accidentally.
• Before cleaning, repairing, or inspecting,

Page 5
remove the battery and make certain all
moving parts have stopped.
• Never spray water directly into the motor
compartment of the machine.
• Use only identical replacement parts when
servicing the machine. Use of unauthorized
parts may create a risk of serious injury to
the user, or damage to the product.

common sense. Do not operate the machine
when you are tired, ill, or upset.
• Don’t use in rain.
• Be aware that the equipment may
unexpectedly bounce upward or jump forward
if the tines should strike buried obstacles such
as large stones, roots, or stumps.
• Wear hearing protection.
• Ensure that people and pets are at least 50’ (15
m) away from the machine while in use.
• Ensure that work area is free of slippery spots
or excessive quantities of stone.
• Start the machine carefully according to
instructions from a normal operating position
and with feet well away from the tines. It will
SAFETY INSTRUCTIONS
do the job better and with less likelihood of
a risk of injury at the rate for which it was
designed.

damaged or modied. Damaged or modied
batteries may exhibit unpredictable behavior
resulting in re, explosion or risk of injury.
• Don’t grasp the exposed cutting blades or
cutting edges when picking up or holding the
machine.
• Do not expose a battery pack or appliance
to re or excessive temperature. Exposure to
fire or temperature above 130°C may cause
explosion. The temperature of 130°C can be
replaced by the temperature of 265°F.

PROPOSITION 65
This product contains a chemical known to
the state of California to cause cancer, birth
defects or other reproductive harm. Some dust
created by power sanding, sawing, grinding,
drilling, and other construction activities
contains chemicals known to cause cancer,
birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints;
• Crystalline silica from bricks and cement
and other masonry products;
• Arsenic and chromium from chemically
treated lumber.
Your risk of exposure to these chemicals
varies depending on how often you do this
type of work. To reduce your exposure to these
chemicals, work in a well-ventilated area, and
work with approved safety equipment, such as
dust masks that are specially designed to lter
out microscopic particles.
CHILD SAFETY
Tragic accidents can occur if the operator is
not aware of the presence of children.
• Keep children out of the working
area and under the watchful care of a
responsible adult.
• Do not allow children under the age
of 14 to operate this blower. Children
who are 14 years of age and older must
read and understand the operating
instructions and safety rules in this
manual and must be trained and
supervised by a parent.
• Stay alert, and turn the blower off if a
child or any other person enters the
working area.
• Use extreme care when approaching
blind corners, doorways, shrubs, trees,
or other objects that may obscure your
view of a child who may run into the
path of the blower.

ing width.
1. Place tine (A) onto the shaft, and place tine
(D) onto the other side shaft.
2. Insert the hitch pin into the holes in order to
secure the tines to the tine shaft.
OPERATION TIPS
The cultivator can be used to break up gar-
den soil and prepare a seedbed for planting.
Plan ahead to leave enough room between
the seed rows to allow for machine cultivating
after the plants have grown.
• Several passes over the same path may be
required to reach the desired depth. Do not
try to dig too deeply in the rst pass.
• If the machine jumps or bucks, allow the
unit to move forward at a slightly faster rate
or install wheel assembly.
• If the cultivator stays and digs in at one
spot, try rocking it from side to side in order
to start it moving forward again.
• If the soil is very hard, water a few days
before cultivating. Avoid working the soil
when soggy or wet. Wait a day or two after
heavy rain for the ground to dry.
• Shallow cultivating less than 5cm. deep
can be used to disrupt weeds and aerate
soil, without injuring nearby plant roots. It
should be done often so that weeds do not
grow large and cause tangling in the tines
of the unit.
