GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS
Failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered and dark areas invite acci-
dents.
Do not operate power tools in explosive atmospheres, such as in the pres-
ence of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed. Children
should never be allowed in the work area.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power tool while tired or under the influence
of drugs, alcohol, or medication. A moment of inattention while operating power
tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, nonskid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions. Al-
ways wear ANSI-approved safety goggles and a dust mask/respirator when using

TOOL USE AND CARE
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed. Do not force
the tool and do not use the tool for a purpose for which it is not intended.
Do not use the power tool if the Engine’s Ignition Switch does not turn it on
or off. Any tool that cannot be controlled with the Ignition Switch is dangerous and
must be replaced.
Disconnect the Spark Plug Wire from the Engine before making any adjust-
ments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally. Always disconnect the
Spark Plug Wire before performing any inspection, maintenance, or cleaning
procedures.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Keep the Mortar Mixer clean. Properly maintained
tools are less likely to malfunction and are easier to control. Do not use a damaged
tool. Tag damaged tools “Do not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts, and any
other condition that may affect the tool’s operation. If damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow instruc-
tions in the “Inspection, Maintenance, And Cleaning” section of this manual.
