WARNING: For your own safety, read all of the instructions and
precautions before operating tool.
PROPOSITION 65 WARNING: Some dust created by using power
tools contain 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.
• 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. Always wear OSHA/NIOSH approved, properly fitting
face mask or respirator when using such tools.
WARNING: Always follow proper operating procedures as defined
in this manual even if you are familiar with the use of this or similar
tools. Remember that being careless for even a fraction of a second
can result in severe personal injury.

• Never leave a tool running unattended.Turn the power off and
do not leave tool until it comes to a complete stop.
• Do not overreach.Keep proper footing and balance.
• Never stand on tool. Serious injury could occur if tool is tipped
over.
• Know your tool. Learn the tool’s operation, application and spe-
cific limitations.
• Use recommended accessories.Understand and obey all safety
instructions supplied with accessories.The use of improper ac-
cessories may cause risk of injury to persons.
• Do not over tighten wheel nut. Replace cracked wheel immedi-
ately. Use only flanges supplied with the grinder.
• Adjust distance between wheel and tool rest to maintain 1/16”
or less gap.
• Handle the workpiece correctly.Whenever possible, use tool
rest to support workpiece during grinding operation.Turn tool
off if it jams.
• Always use guards and eyeshields.
• Clean grinding dust from beneath tool frequently.
CAUTION: Think safety! Safety is a combination of operator com-
mon sense and alertness at all times when tool is being used.

GROUNDING INSTRUCTIONS
WARNING: Improper connection of equipment grounding con-
ductor can result in the risk of electrical shock. Equipment should
be grounded while in use to protect operator from electrical shock.
Check with a qualified electrician if grounding instructions are not
understood or if in doubt as to whether the tool is properly
grounded.
This grinder is equipped with an approved 3-conductor cord rated
at 300V and a 3-prong,grounding type plug (See Figure 2) for your
protection against shock hazards.
Grounding plug should be plugged directly into a properly in-
stalled and grounded 3-prong grounding-type receptacle (See
Figure 2).
Do not remove or alter grounding prong in any manner. In the
event of a malfunction or breakdown, grounding provides a path of
least resistance for electrical shock.
WARNING: Do not permit fingers to touch the terminals of plug
when installing or removing from outlet.
Plug must be plugged into matching outlet that is properly in-
stalled and grounded in accordance with all local codes and ordi-
nances. Do not modify plug provided.If it will not fit in outlet, have
proper outlet installed by a qualified electrician.
Inspect tool cords periodically, and, if damaged, have repaired by an
authorized service facility.
Green (or green and yellow) conductor in cord is the grounding
wire. If repair or replacement of the electric cord or plug is neces-
sary,do not connect the green (or green and yellow) wire to a live
terminal.
Where a 2-prong wall receptacle is encountered, it must be re-
placed with a properly grounded 3-prong receptacle installed in
accordance with National Electric Code and local codes and
ordinances.
WARNING: This work should be performed by a qualified
electrician.
A temporary 3-prong to 2-prong grounding adapter (See Figure 3)
is available for connecting plugs to a two pole outlet if it is properly
grounded.
Do not use a 3-prong to 2-prong grounding adapter unless permit-
ted by local and national codes and ordinances.
(A 3-prong to 2-prong grounding adapter is not permitted in
Canada.) Where permitted, the rigid green tab or terminal on the
side of the adapter must be securely connected to a permanent
electrical ground such as a properly grounded water pipe,a prop-
erly grounded outlet box or a properly grounded wire system.
Many cover plate screws, water pipes and outlet boxes are not
properly grounded.To ensure proper ground, grounding means
must be tested by a qualified electrician.
