2 IMPORTANT SAFETY
INSTRUCTIONS
READ ALL INSTRUCTIONS BEFORE USING (THIS
POWER TOOL)
WARNING
Read and understand all instructions before using this
product. Failure to follow all instructions listed below may
result in electric shock, fire, and/or serious personal injury.
• Use only identical manufacturer’s replacement parts and
accessories. Use of any other parts may create a hazard or
cause product damage.
• Always wear safety glasses with side shields marked to
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
face mask if operating in dusty work spaces.
• Avoid Dangerous Environment – Don’t expose power
tools to damp or wet conditions. Water entering a power
tool will increase the risk of electric shock.
• Don’t use in rain.
• Keep all bystanders, children, and pets at least 50 ft.
away.
• 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.
• Use right Appliance. Do not use appliance for any job
except that for which it is intended.
• Avoid Unintentional Starting – Don’t carry appliance
with finger on switch. Be sure switch is off when battery
is plugged in.
• Don’t Force Appliance – It will do the job better and with
less likelihood of a risk of injury at the rate for which it
was designed.
• Don’t overreach – Keep proper footing and balance at all
times.
• Stay alert – Watch what you are doing. Use common
sense. Do not operate this unit when you are tired, ill or
under the influence of alcohol, drugs or medication.
• Always store idle power tools indoors – When not in use,
power tools should be stored indoors in a dry and high or
locked-up place, out of reach of children.
• Maintain Appliance With Care – Replace string head if
cracked, chipped, or damaged in any way. Be sure the
string head is properly installed and securely fastened.
Keep cutting edge sharp and clean for best performance

and to reduce the risk of injury. Follow instructions for
lubricating and changing accessories. Inspect appliance
cord periodically, and if damaged, have it repaired by an
authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry,
clean, and free from oil and grease. Failure to do so can
cause serious injury.
• Check damaged parts before using the appliance, a guard
or other part that is damaged should be carefully checked
to determine that it will operate properly and perform its
intended function. Check for alignment of moving parts,
binding of moving parts, breakage of parts, damaged
mountings, and any other condition that may affect its
operation. A guard or other part that is damaged should
be properly repaired or replaced by an authorized service
center unless indicated elsewhere in this manual.
• Remove or disconnect battery before servicing, cleaning
or removing material from the gardening appliance.
• Do not modify or attempt to repair the appliance or the
battery pack (as applicable) except as indicated in the
instructions for use and care. Use appliances only with
specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire. Use
only Greenworks 60BA02/60BA25/60BA03/
60BA04/60BA05/60BA06/ 60BA08 battery or other
BAC series.
• Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack. Use only Greenworks
60DP10/606P14 charger or other CAC series.
• When battery pack is not in use, keep it away from other
metal objects, like paper clips, coins, keys, nails, screws
or other small metal objects, that can make a connection
from one terminal to another. Shorting the battery
terminals together may cause a fire.
• Under abusive conditions, liquid may be ejected from the
battery; avoid contact. If contact accidentally occurs,
flush with water. If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery may cause
irritation or burns.
• Do not use a battery pack or appliance that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
of injury.
• Do not expose a battery pack or appliance to fire or
excessive temperature. Exposure to fire or temperature
above 265 °F (130 °C) may cause an explosion.
• Do not dispose of the batteries in a fire. The cells may
explode. Check with local codes for possible special
disposal instructions.
• Do not open or mutilate the batteries. Released electrolyte
is corrosive and may cause damage to the eyes or skin. It
may be toxic if swallowed.
• Exercise care in handling batteries in order not to short
the battery with conducting materials such as rings,
bracelets, and keys. The battery or conductor may
overheat and cause burns.
• Follow all charging instructions and do not charge the
battery pack or appliance outside of the temperature range
specified in the instructions. Charging improperly or at
temperatures outside of the specified range may damage
the battery and increase the risk of fire.
• Have servicing performed by a qualified repair person
using only identical replacement parts. This will ensure
that the safety of the product is maintained.
• Keep guards in place and in working order.
• Keep hands and feet away from cutting area.
• 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.
• Use only with the nylon cutting line of 0.095" (2.4 mm)
diameter. Do not use heavier lines than recommended by
the manufacturer and line materials of other types – for
example, metal wire, rope, and the like.
• Be aware of blade thrust :
• Blade thrust may occur when the spinning blade
contacts an object that it does not immediately cut.
• Blade thrust can be violent enough to cause the unit
and/or operator to be propelled in any direction, and
possibly lose control of the unit.
• Blade thrust can occur without warning if the blade
snags, stalls or binds.
• Blade thrust is more likely to occur in areas where it
is difficult to see the material being cut.
• Condition of Unit before Use – The handles shall be
mounted in accordance with the manufacturer’s
instructions. Do not attach any blade to a unit without
proper installation of all required parts. Failure to use the
proper parts can cause the blade to fly off and seriously
injure the operator and/or bystanders. Discard blades that
are bent, warped, cracked, broken, or damaged in any
way. Use a sharp blade. A dull blade is more likely to
snag and thrust.
