• Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools that have the switch on invites accidents.
• Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that
is left attached to a rotating part of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and bal-
ance enables better control of the tool in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for appropriate conditions.
TOOL USE AND CARE
• Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to loss of
control.
• Do not force 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 use tool 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 plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventative safety measures reduce the risk of
starting the tool accidentally.
• Store idle tools out of reach of children and other untrained persons. Tools are dan-
gerous in the hands of untrained users.
• Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind and are easier to control.
• 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 mainte-
nance performed by unqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow mainte-
nance instructions may create a risk of electric shock or injury.
Additional Specific Safety Instructions for Masonry Saws
• Do not reach underneath the work. The guard can not protect you from the blade below
the work.
• NEVER hold piece being cut in your hands or across your leg. It is important to support
the work properly to minimize body exposure, blade binding, or loss of control.
• Hold tool by insulated gripping surfaces when performing an operation where the cut-
ting tool may contact hidden wiring. Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
• Always use blades with correct size [(5/8" (16 mm)] and shape (round) arbor holes.
Blades that do not match the mounting hardware of the saw will run eccentrically, causing
loss of control.
• Never use damaged or incorrect blade washers or bolts. The blade washers and bolts
were specially designed for your saw, for optimum performance and safety of operation.
• Don’t unplug if plug or receptacle is wet. Disconnect the fuse or circuit breaker that sup-
plies power to the tool. Then unplug and examine for presence of water in the receptacle.
• Wait for the saw to come to a complete stop. An unprotected, coasting blade will cause the
saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the
blade to stop after switch is released.
• Never use any blades with expansion or segmented (toothed) rims. This tool is not
equipped with a lower guard.
WARNING: Keep hands away from cutting area and blade. Personal injury may result.
WARNING: Always plug extension cord into a GFCI protected outlet.
WARNING: To reduce the risk of electrocution, keep all connections dry and off the ground.
Do not touch plug with wet hands.
WARNING: A Ground Fault Circuit Interrupter (GFCI) is provided on the cord set.
Receptacles are available having built in GFCI protection and may be used for an added mea-
sure of safety. When using an extension cord, always plug into a GFCI protected receptacle or
outlet.
WARNING: Test GFCI before each use:
1. Plug GFCI into power outlet. Indicator should turn red.
2. Press test button. Red indicator should disappear.
3. Press reset button for use. Do not use if above test fails.
WARNING: Never use saw with salt water or a conductive fluid.
WARNING: Always use eye protection. All users and bystanders must wear eye protection
that conforms to ANSI Z87.1.
CAUTION: WHEN SERVICING USE ONLY IDENTICAL REPLACEMENT PARTS. Repair or
replace damaged cords.
CAUTION: Do not connect unit to electrical power source until complete instructions are read
and understood.
CAUTION: Wear appropriate hearing protection during use. Under some conditions and
duration of use, noise from this product may contribute to hearing loss.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to the State of California 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, and
• arsenic and chromium from chemically-treated lumber (CCA).
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 filter out microscopic
particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
