IMPORTANT SAFETY INFORMATION
The following explanations are displayed in this manual, on the labeling,
and on all other information provided with this product:
GENERAL SAFETY RULES
Read all instructions. Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1) WORK AREA SAFETY
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.

4Eastwood Technical Assistance: 800.343.9353 >> [e-mail]
2) ELECTRICAL SAFETY
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
NOTE: Use a minimum 14 gauge insulated cord, no longer than 25’ in length.
3) PERSONAL SAFETY
a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will
reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your finger on the switch or plugging in power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control
of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of these devices can reduce dust-related hazards.

4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the correct power tool for your application. The correct power
tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before
making any adjustments, changing accessories, or storing power tools. Such preventive safety
measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the
hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the power tools operation. If damaged, have the power
tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these instructions and
in the manner intended for the particular type of power tool, taking 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.

HEALTH AND INJURY HAZARDS!
• Dust and fine particulate matter is generated during the sanding/grinding
process which can contain toxic substances such as lead, silica, solvents
and others. Breathing this dust and fine particulate matter can cause many
serious respiratory health conditions. Always use NIOSH approved respira-
tory protection while using this tool.
• This tool will eject particles, dust and sparks at high velocity during opera-
tion. Wear approved eye and skin protection at all times while operating.
• Sanding and grinding can generate excessive noise. Wear appropriate
hearing protection while using.
• The rotating drum of this tool can quickly catch loose clothing, long hair or
jewelry causing serious personal injury. Keep all loose clothing, long hair
and jewelry away from operating tool.
• Always unplug the tool from the electrical supply before changing drums.
• Rotating abrasive drums can quickly remove flesh. Keep hands and fingers
away from rotating components and always wear protective work gloves
while sanding/cleaning.
• This tool can quickly and violently kick back or twist while operating caus-
ing severe hand and or wrist injury. Do not apply excessive force to tool
while in use. Use only on broad, open spaces using care to avoid edges
and corners. If smaller objects are being sanded, be sure they are securely
mounted or anchored before beginning.
• Incorrectly rated drums can disintegrate at high RPM causing serious
personal injury. Always use replacement drums rated for 3700 RPM
operation or greater.
• Damaged drums can disintegrate at high speed causing personal injury or
property damage. If excessive vibration is felt, discontinue use immediately
and disconnect tool from electrical supply. Inspect drum and tool for
damage. Do not resume use until resolution is found.
• This tool will eject a trail of sparks at high speed which can ignite
flammable materials or injure others nearby. Do not operate in the
vicinity of flammable materials and keep all persons and pets away
from the work area.
• Always make sure the workpiece being buffed/cleaned/sanded is securely
clamped or anchored to allow two handed operation of the tool.

ASSEMBLY
1. Place "D" Handle with curves facing forward and with ends over recessed areas of tool body.
2. Insert 2 Socket Head Cap Screws through the holes in "D" Handle and into threaded holes in
tool body. Tighten screws securely.
OPERATION
1. Set desired motor speed by rotating the Speed Knob located on the top surface of the
Motor Housing. To the left = Low (1), to the right = High (6) (FIG 1).
2. While holding the Contour SCT securely in two hands, depress the On-Off switch with
forefinger (FIG 1). IMPORTANT NOTE: The built-in Soft-Start feature will cause a slight
delay in motor starting and gradually increase in speed. This feature is designed to eliminate
the possibility of the tool “pulling” at startup
3. For extended use, lock the On-Off switch in the ON position. To lock the On-Off switch in the
ON position, depress the On-Off switch fully then push in the Lock Button located above the
Switch on the left side of the Handle. To release lock, depress the On-Off switch (FIG 1).
4. Keep the broad work surface of the Drum parallel to the work surface whenever possible to
minimize uneven wear and maximize usable life.
5. Always use two hands while operating tool, do not force but allow the rotational speed of
the drum to do the work.
6. Be sure that the workpiece is clamped down or held securely to always allow two hands
to operate tool. NOTE: Only use a speed fast enough to remove coatings and keep wheel
turning. Too fast will heat the metal.
Unplug unit before assembly.
