• 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
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 (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.
