Additional Safety Rules For Routers; Additional Safety Information - DeWalt DW621 Instruction Manual

into account the working conditions and the
work to be performed. Use of the power tool for
operations different from those intended could result
in a hazardous situation.
5) Service
a ) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.

Additional Safety Rules for Routers

• Hold power tool by insulated gripping surfaces
because the cutter may contact its own cord. Cutting
a "live" wire may make exposed metal parts of the power
tool "live" and shock the operator.
• Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the work by your hand or against the body leaves it
unstable and may lead to loss of control.
Metal cutting with router: If using router for metal
•
cutting, clean out tool often. Metal dust and chips
often accumulate on interior surfaces and could create a
risk of serious injury, electrical shock or death.
• Never run the motor unit separate from the base. The
motor is not designed to be handheld.
• Keep handles dry, clean and free from oil and
grease. This will enable better control of the tool.
• Maintain a firm grip with both hands on the tool to
resist starting torque. Maintain a firm grip on the tool
at all times while operating.
• USE SHARP CUTTERS. Dull cutters may cause the router
to swerve or stall under pressure.
Keep hands away from cutting area above and
•
below the base. Never reach under the workpiece for
any reason. Keep the router base firmly in contact with
the workpiece when cutting.
• Never touch the bit immediately after use. It may be
extremely hot.
• Be sure that the motor has stopped completely
before you lay the router down. If the bit is still
spinning when the tool is laid down, it could cause injury
or damage.
• Be sure that the router bit is clear of the workpiece
before starting the motor. If the bit is in contact with
the workpiece when the motor starts, it could make the
router jump, causing damage or injury.
Always follow the bit manufacturer's speed
•
recommendations as some bit designs require
specific speeds for safety or performance. If you are
unsure of the proper speed or are experiencing any type of
problem, contact the bit manufacturer.
Do not use router bits with a diameter in excess of
•
2–3/8" (60 mm) in this tool.
• Do not hand-hold the router in an upside-down or
horizontal position. The motor can separate from the
base if not properly attached according to the instructions.

• Before starting the motor, check to see that the cord
will not snag or impede the routing operation.
• Before starting the motor, clear the work area of all
foreign objects.
Keep cutting pressure constant. Do not
•
overload motor.
• Provide clearance under workpiece for bit when
through-cutting.
• Do not press spindle lock button while the motor is
running. Doing so can damage the spindle lock.
• Always make sure the work surface is free from nails
and other foreign objects. Cutting into a nail can cause
the bit and the tool to jump.
• 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
for safety. 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.

Additional Safety Information


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.
