Additional Safety Information
• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long
hair can be caught in moving parts.
• An extension cord must have adequate wire size (AWG or American Wire Gauge) for
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up
the total length, be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the
cord.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use
face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction 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.
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 disperse 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.
WARNING: Always wear proper personal hearing protection that conforms to ANSI
S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this product
may contribute to hearing loss.
WARNING: Always use eye protection. All users and bystanders must wear eye protection
that conforms to ANSI Z87.1.
WARNING: When not in use, place grinder on a stable surface where it will not move
inadvertantly, roll or cause a tripping or falling hazard. Serious personal injury may result.
CAUTION: To reduce the risk of personal injury, use extra care when working into a corner or
edge because a sudden, sharp movement of the tool may be experienced when the wheel or other
accessory contacts a secondary surface or a surface edge.

2. Remove mounting nut by turning it counterclockwise (when facing outer side of wheel). The
spindle can be held stationary by holding a wrench on the flats provided on the exposed portion
of the spindle.
3. When installing the new grinding wheel, always use blotters between the wheel and each
surface it contacts (all grinders). For straight grinders, use the clamp washers, supplied with
tool, on either side of the grinding wheel.
4. Only tighten arbor nut sufficiently to drive the wheel without slippage.
5. Be sure to replace guard end cover.
WARNING: Grasp tool firmly with both hands to maintain control of the tool at start up and
during use and until the wheel or accessory stops rotating. Make sure the wheel has come to a
complete stop be fore laying the tool down.
Put the work in a vise or clamp it securely. Use a face mask over the nose and mouth if the
operation raises dust. Treat the wheel with respect. Do not jam the wheel into the work or use
unnecessary pressure. Grind only on the periphery of the wheel (Fig. 2), unless you have a special
wheel specifically made to permit grinding on the side of the wheel.
Using Wire Wheels
Wire wheels and brushes can be used for removing rust, scale and paint, and for smoothing
irregular surfaces.
1. Allow the tool to reach full speed before touching the tool to the work surface.
2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. Material
removal rate is greatest when the tool operates at high speed.
3. Continuously move the tool on the work to avoid creating gouges in the work surface. Allowing
the tool to rest on the work surface without moving, or moving the tool in a circular motion
causes burning and swirling marks on the work surface.
4. Remove the tool from the work surface before turning the tool off. Allow the tool to stop rotating
before setting it down.
CAUTION: Use extra care when working over an edge, as a sudden sharp movement of grinder
may be experienced.
MAINTENANCE
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect tool
from power source before making any adjustments or removing/installing attachments
or accessories. Before reconnecting the tool, depress and release the trigger switch to
ensure that the tool is off.
Cleaning
WARNING: Blowing dust and grit out of motor and switch actuator using clean, dry compressed
air is a necessary regular maintenance procedure. Dust and grit containing metal particles often
accumulate on interior surfaces and could create an electrical shock or electrocution if not
frequently cleaned out. It is recommended that a ground fault circuit interrupter (GFCI) is utilized to
further protect the user from electric shock resulting from the accumulation of conductive particles.
If the tool is deactivated by the GFCI, unplug the tool and check and clean the tool before resetting
the GFCI. ALWAYS WEAR SAFETY GLASSES (ANSI Z87.1) when cleaning or using this tool.
WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts
of the tool. These chemicals m ay weaken the plastic materials used in these parts. Use a cloth
dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse
any part of the tool into a liquid.

Your power tool requires no additional lubrication.
Motor Brushes
Be sure tool is unplugged before inspecting brushes. Carbon brushes should be regularly inspected
for wear. To inspect brushes, unscrew the plastic brush inspection caps (located in the sides of the
motor housing) and the spring and brush assemblies may be withdrawn from the tool. Keep brushes
clean and sliding freely in their guides. Carbon brushes have varying symbols stamped into them,
and if the brush is worn down to the line closest to the spring, they must be replaced. New brush
assemblies are available at your local service center.
