This manual provides critical safety instructions on the proper setup,
operation, maintenance, and service of this machine/tool. Save this
document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual
may result in fire or serious personal injury—including amputation,
electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in
a safe environment, personnel training and usage authorization,
proper inspection and maintenance, manual availability and compre­hension, application of safety devices, cutting/sanding/grinding tool
integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage
from negligence, improper training, machine modifications or misuse.

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, cement and other masonry products.

• 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.

SECTION 1: SAFETY

For Your Own Safety, Read Instruction

Manual Before Operating This Machine

The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor­tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.

Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.

Always discon-

Model G4181/G7873 (Mfd. Since 12/13)

WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate­rial. Always wear a NIOSH-approved respirator to
reduce your risk.

HEARING PROTECTION. Always wear hear­ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica­tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.

FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.

NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement dur­ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec­ommended accessories. Using improper acces­sories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.

MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.

DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!

MAINTAIN POWER CORDS. When disconnect­ing cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.

EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend­ed operation, stop using the machine! Contact our
Technical Support at [phone].
