starting the tool accidentally.
16. Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.
17. When battery pack is not in use, keep it away
from other metal objects like: paper clips,
coins, keys, nails, screws, or other small metal
objects that can make a connection from one
terminal to another. Shorting the battery
terminals together may cause sparks, burns, or a
fire.
18. 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.
19. 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.
20. Use only accessories that are recommended
by the manufacturer for your model.
Accessories that may be suitable for one tool may
create a risk of injury when used on another tool.
Service
21. Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified personnel
could result in a risk of injury.
22. 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 Maintenance
instructions may create a risk of shock or injury.

SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to grinder safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious personal
injury.
1. Always use proper guard with grinding wheel.
A guard protects operator from broken wheel
fragments.
2. Accessories must be rated for at least the
speed recommended on the tool warning label.
Wheels and other accessories running over rated
speed can fly apart and cause injury.
3. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring. Contact with a "live"
wire will make exposed metal parts of the tool
"live" and shock the operator.
4. When using depressed center grinding wheels,
be sure to use only fiberglass-reinforced
wheels.
5. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT safety
glasses.
6. Check the wheel carefully for cracks or
damage before operation. Replace cracked or
damaged wheel immediately. Run the tool
(with guard) at no load for about a minute,
holding tool away from others. If wheel is
flawed, it will likely separate during this test.
7. Use only flanges specified for this tool.
8. Be careful not to damage the spindle, the
flange (especially the installing surface) or the
lock nut. Damage to these parts could result in
wheel breakage.
9. NEVER use tool with wood cutting blades or
other sawblades. Such blades when used on a
grinder frequently kick and cause loss of
control leading to personal injury.
10. Hold the tool firmly.
11. Keep hands away from rotating parts.
12. Make sure the wheel is not contacting the
workpiece before the switch is turned on.
13. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.
14. Use the specified surface of the wheel to
perform the grinding.
15. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.
16. Do not leave the tool running. Operate the tool
only when hand-held.
17. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.
18. ALWAYS wear proper apparel including long
sleeve shirts, leather gloves and shop aprons
to protect skin from contact with hot
grindings.
19. Use of this tool to grind or sand some
products, paints and wood could expose user
to dust containing hazardous substances. Use
appropriate respiratory protection.
20. NEVER USE Stone Cup type wheels with this
grinder. This grinder is not designed for these
types of wheels and the use of such a product may
result in serious personal injury.
