9. USE PROPER EXTENSION CORD. 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. An undersized cord will
cause a drop in line voltage resulting in loss
of power and overheating. Table A 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.
10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings, bracelets,
or other jewelry which may get caught in moving
parts. Nonslip footwear is recommended.
Wear protective hair covering to contain long hair.
11. ALWAYS USE SAFETY GLASSES. Also use
face or dust mask if cutting operation is dusty.
Everyday eyeglasses only have impact resistant
lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than using
your hand and it frees both hands to operate tool.
13. DON’T OVERREACH.
Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep
tools sharp and clean for best and safest
performance. Follow instructions for
lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing
when changing accessories, such as
blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in
off position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended
accessories. The use of improper accessories
may cause risk of injury to persons.
18. NEVER STAND ON TOOL.
Serious injury could occur if the tool is tipped or
if the cutting tool is unintentionally contacted.
19. 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.
20. DIRECTION OF FEED.
Feed work into a blade or cutter against the
direction of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.

GrOunDinG WirE cOnnEctiOn rEaD anD FOLLOW tHESE inStructiOnS:
110-120 Vac Grounded tools: tools with three prong plugs
1. In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
2. Do not modify the plug provided – if it will
not fit the outlet, have the proper outlet
installed by a qualified electrician.
3. Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
The conductor with insulation having an outer
surface that is green with or without yellow
stripes is the equipment-grounding conductor.
If repair or replacement of the electric cord or
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
4. Check with a qualified electrician or service
personnel if the grounding instructions are
not completely understood, or if in doubt as
to whether the tool is properly grounded.
5. Use only 3-wire extension cords that
have 3-prong grounding plugs and 3-pole
receptacles that accept the tool’s plug.
6. Repair or replace damaged or
worn cord immediately.

Sander Safety Warnings
For your Own Safety read instruction
Manual Before Operating Sander
1. Wear eye protection.
2. Support workpiece with miter gauge,
backstop, or worktable.
3. Maintain 1/16 inch maximum clearance
between table and sanding belt or disc.
4. Avoid kickback by sanding in accordance
with the directional arrows.
5. The backstop is a fence near the surface that
helps the operator maintain control of the
workpiece and prevents the workpiece from being
pulled into the machine. For safety, it must be
adjusted very close to the sanding surface.
6. The worktable is the surface mounted close to
the sanding surface that the operator rests the
workpiece against to prevent it from being pulled
adjusted very close to the sanding surface.
7. The sanding belt is designed to rotate down towards
the table while the disc rotates both up from the
table and down towards the table. Sand on the
belt with the workpiece in front of the backstop
and/or table. Sand only on the downward moving
surface of the disc - sanding on the upward
moving surface may result in the workpiece
being thrown up and towards the operator.
8. Remove Safety Key when the Switch is
turned off. Do not leave the Safety Key in
the Switch when the tool is not in use.

9. DO nOt OpEratE WitH any GuarD
DiSaBLED, DaMaGED, Or rEMOVED. Moving
guards must move freely and close instantly.
10. The use of accessories or attachments not
recommended by the manufacturer may
result in a risk of injury to persons.
11. When servicing use only identical replacement parts.
12. Only use safety equipment that has been approved
by an appropriate standards agency. Unapproved
safety equipment may not provide adequate

discussed in this instruction manual cannot cover all
possible conditions and situations that may occur.
It must be understood by the operator that
common sense and caution are factors
which cannot be built into this product,
but must be supplied by the operator.
Vibration Safety
This tool vibrates during use. Repeated or long-
term exposure to vibration may cause temporary
or permanent physical injury, particularly to
the hands, arms and shoulders. To reduce
the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical check-ups
to ensure medical problems are not being caused
or worsened from use. Pregnant women or
people who have impaired blood circulation to
the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
