SERVICE
Tool service must be performed only by qualified
repair personnel. Service or maintenance performed by
unqualified personnel may 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 Maintenance Instructions may create a risk of
shock or injury.
GENERAL SAFETY RULES
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will make exposed metal parts of the cutting
tool “live” and shock the operator.
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.
Know your power tool. Read operator’s manual
carefully. Learn its applications and limitations, as well
as the specific potential hazards related to this tool.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
Always wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT safety
glasses. Following this rule will reduce the risk of serious
personal injury.
Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the risk
of serious personal injury.
Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have
repaired at your nearest Authorized Service Center.
Constantly stay aware of cord location. Following this
rule will reduce the risk of electric shock or fire.
Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will operate
properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced
by an authorized service center. Following this rule will
reduce the risk of shock, fire, or serious injury.
Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension cord 50 feet or less in
length. A cord exceeding 100 feet is not recommended.
If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating.
Inspect for and remove all nails from lumber before
using this tool. Following this rule will reduce the risk of
serious personal injury.
Do not operate the flexible shaft with a sharp bend.
Over bending the shaft can generate excessive heat on
the jacket or hand piece. The recommended minimum
bend radius is 6 in.
After changing bits or making any adjustments, make
sure the collet nut and any other adjustment devices
are securely tightened. A loose adjustment device can
unexpectedly shift, causing loss of control. Loose rotating
components will be violently thrown.
Do not reach in the area of the spinning bit. The
proximity of the spinning bit to your hand may not always
be obvious.
Do not grind or sand heat flammable materials. Sparks
from the wheel could ignite these materials.
This product is not intended for use as a dental drill or
in human or veterinary medical applications. Serious
injury may result.
When using steel screws, cut-off wheels, high speed
cutters, or tungsten carbide cutters, always have
the work securely clamped. Never attempt to hold
the work with one hand while using any of these
accessories.
If the power supply cord is damaged, it must be replaced
only by the manufacturer or by an authorized service
center to avoid risk.
Save these instructions. Refer to them frequently and
use them to instruct others who may use this tool. If you
loan someone this tool, loan them these instructions
also.
