WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
• Do not allow to be used as a toy. Close attention
is necessary when used by or near children.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate
the power tool. Power tools are dangerous in the
hands of untrained users.
• Do not use the tool near anything that is burning or
smoking such as cigarettes, matches, or hot ashes.
•To reduce the risk of health hazards from vapors
or dust, do not use tool near tool toxic, carcinogenic or other hazardous materials such as as-
bestos, arsenic, barium, beryllium, lead, pesticides
or other health endangering materials.
ELECTRICAL SAFETY
• Do not expose power tools to rain or wet conditions. Do not immerse in water or spray with a
hose. Do not clean with a pressure washer. Water
entering a power tool will increase the risk of electric
shock. Store tool indoors.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under

WARNING
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 paint
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures 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 those dust masks that are specially designed to
lter out microscopic particles.

• Do not drag the spool cover along the ground or
bump it too hard. Only bump spool on the ground.
Do not bump against rocks, driveways, etc.
• Make multiple passes in long growth.
• Avoid ornamental trees, shrubs, and plantings. Avoid
contact with siding, fence posts, etc. They can all
be damaged by the trimmer.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the tool, battery pack or charger. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tool
Keep your tool, battery pack and charger in good
