NOTICE
Safety Instructions for Power Tools
OWNER’S MANUAL. Read and under-
stand 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 power tool. When tool
is not being used, disconnect power, and
store in out-of-reach location to prevent
unauthorized use—especially around
children. Make workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not
use tools in areas that are wet, cluttered,
or have poor lighting. Operating tools in
these areas greatly increases risk of acci-
dents and injury.
MENTAL ALERTNESS REQUIRED. Full
mental alertness is required for safe oper-
ation of power tools. Never operate under
the influence of drugs or alcohol, when
tired, or when distracted.
DISCONNECT POWER FIRST. Always
disconnect tool from power supply
BEFORE making adjustments, changing
tooling, or servicing machine. This pre-
vents 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.

Model T33306 (Mfd. Since 11/22)-2-
ELECTRICAL SAFETY. Tool plug must
match outlet. Double-insulated tools have
a polarized plug (one blade is wider than
the other), which must be plugged into a
polarized outlet. Never modify plug. Do
not use adapter for grounded tools. Use
a ground fault circuit interrupter if opera-
tion is unavoidable in damp locations.
Avoid touching grounded surfaces when
operating tool.
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 avoid accidental
slips, which could cause loss of workpiece
control. Wear hard hat as needed.
HAZARDOUS DUST. Dust created while
using tools 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, and con-
nect tool to an appropriate dust collection
device 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. Never
leave adjustment tools, chuck keys,
wrenches, etc. in or on tool—especially
near moving parts. Verify removal before
starting!
INTENDED USAGE. Only use tool for its
intended purpose. Never modify or alter
tool for a purpose not intended by the
manufacturer or serious injury or death
may result!
AWKWARD POSITIONS. Keep proper
footing and balance at all times when
operating tool. Do not overreach! Avoid
awkward hand positions that make tool
control difficult or increase the risk of
accidental injury.
SAFE HANDLING. Firmly grip tool. To
avoid accidental firing, do not keep finger
on switch or trigger while carrying.
FORCING TOOLS.. Use right tool for job,
and do not force it. It will do job safer and
better at rate for which it was designed.
SECURING WORKPIECE. When
required, use clamps or vises to secure
workpiece. This protects hands and frees
both of them to operate tool.
GUARDS & COVERS. Guards and cov-
ers reduce accidental contact with mov-
ing parts or flying debris. Ensure they
are properly installed, undamaged, and
working correctly.
CHILDREN & BYSTANDERS. Keep chil-
dren and bystanders at a safe distance
from the work area. Stop using tool if they
become a distraction.
USE RECOMMENDED ACCESSORIES.
Consult this manual or manufacturer
for recommended accessories. Using
improper accessories will increase risk of
serious injury.
MAINTAIN WITH CARE. Keep cutting
tool edges sharp and clean. Follow all
maintenance instructions and lubrication
schedules to keep tool in good work-
ing condition. A tool that is improperly
maintained could malfunction, leading to
serious personal injury or death. Only
have tool serviced by qualified service-
personnel using matching replacement
parts.
CHECK DAMAGED PARTS. Regularly
inspect tool for any condition that may
affect safe operation. Immediately repair
or replace damaged or mis-adjusted parts
before operating tool.
MAINTAIN POWER CORDS. When dis-
connecting cord-connected tools from
power, grab and pull the plug—NOT the
cord. Carrying or pulling the cord may
damage 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, sharp
edges, moving parts, and wet/damp loca-
tions. Damaged cords increase risk of
electrocution.
UNATTENDED OPERATION. Never
leave tool running while unattended. Turn
tool OFF and ensure all moving parts
completely stop before walking away.
EXPERIENCING DIFFICULTIES.
If at
any time you experience difficulties per-
forming the intended operation, stop
using the machine! Contact our Technical
Support at [phone].

Additional Safety for Sanders
Serious injury can occur from getting clothing, jewelry, or long hair entangled
in rotating pad. Flying debris can cause eye injuries or blindness. Rotating pad
may pinch or snag and cause tool to strike operator. To reduce the risk of these
hazards, operator and bystanders MUST completely heed hazards and warnings
below.
AVOIDING ENTANGLEMENT. Do not
wear loose clothing, gloves, or jewelry.
Tie back long hair. Always allow tool to
stop on its own. Do not place hands near,
or in contact with, backing pad during
operations.
PERSONAL PROTECTIVE EQUIPMENT
(PPE). Sanding can create large amounts
of dust and can lead to eye injury or respi-
ratory illness. Sanding toxic material,
like asbestos or lead-based paint, can
deposit material into the air and create a
respiratory hazard. Always wear safety
glasses and a respirator.
KICKBACK. Sharp corners or edges on
workpiece can snag or grab sanding disc,
so maintain a firm grip with both hands
on tool and position body and arms to
resist kickback forces. Always use tool
handles for maximum control over kick-
back. Do not position your body where
tool or workpiece will propel in event of
kickback.
USE FOR INTENDED PURPOSE. This
tool is designed to sand wood, metal,
fiberglass, plastic, and composite surfac-
es. DO NOT use tool to perform grinding,
wire brushing, hole cutting, wet sand-
ing, or cut-off operations. Doing so may
damage tool or cause personal injury.
O n l y u s e t h i s s a n d e r f o r d r y s a n d i n g
operations.
DISC CAPACITY. Diameter and speed
rating of disc or accessories must
be within capacity rating of your tool.
Incorrectly-sized discs and accessories
should not be used.
SANDING DISCS. Inspect discs and
backing pad before use. DO NOT use
discs that show signs of excessive wear
or damage. Used discs can become dis-
lodged and may cause damage to tool or
work surface. Make sure pad is properly
installed before use. Never use modified
discs for operations.
STARTING TOOL. Never start tool while
pad is contacting workpiece. Before using
tool, allow it to reach full speed to see if
there is any vibration or wobbling. This
could indicate poor installation of pad.
Disconnect battery, re-install pad before
resuming operations. Always move power
switch to OFF position before attaching
battery.
WORKPIECE INSPECTION. Nails, sta-
ples, knots, or other imperfections in
workpiece can be dislodged and thrown
by sander at high rate of speed into
operator or bystanders, or cause damage
to tool, sanding disc, or pad. Never try to
sand stock that has embedded foreign
objects or questionable imperfections.
Make sure workpiece is properly sup-
ported.
OPERATION. Make sure tool comes to a
complete stop before setting tool down.
DO NOT touch workpiece or any acces-
sories after operation, as surfaces may
be extremely hot and can cause burns.
Never place hand near rotating acces-
sory. DO NOT operate tool for extended
periods of time. Vibration from tool can
cause permanent damage to fingers,
hands, and arms. DO NOT use tool near
flammable materials. DO NOT use acces-
sories that require liquid coolants.
MAINTENANCE. Dust and grit often
accumulate on tool and can create an
electric shock hazard. Wipe tool with a
clean rag after use and make sure motor
vents are clear.
LEAD-BASED PAINT. Sanding of lead-
based paint is not recommended. Lead
paint can be difficult to identify. Use extra
precautions sanding paint. Use PPE, do
not eat or drink in the area, and keep
pregnant women and children out of the
area. In addition, all sanded areas should
be vacuumed and cleaned at the end of
operations. Sanding discs and other items
used should be disposed of properly.

SECTION 4: OPERATIONS
Operation Overview
The purpose of this overview is to provide
the novice machine operator with a basic
understanding of how the tool is used
during operation, so the tool controls/com-
ponents discussed later in this manual are
easier to understand.
Due to the generic nature of this overview,
it is not intended to be an instructional
guide. To learn more about specific opera-
tions, read this entire manual, seek addi-
tional training from experienced machine
operators, and do additional research out-
side of this manual by reading "how-to"
books, trade magazines, or websites.
To complete a typical operation, the
operator does the following:
1. Examines workpiece to make sure it is
suitable for sanding.
2. Secures workpiece.
3. Installs correct sanding disc for
operation.
4. Puts on safety glasses and respirator.
5. Holds tool with one hand on handle
and other hand on D-handle.
6. Starts tool at lowest speed, waits for
tool to reach full speed.
7. Places sanding pad on workpiece,
then begins sanding with even, steady
motion.
Note: Always do a test run on a
small area of workpiece to make sure
desired result is achieved.
8. Removes tool from workpiece,
stops tool, then allows tool to come
to complete stop before setting tool
down.
To reduce your risk of
serious injury, read
this entire manual
BEFORE using tool.
Eye injuries and respiratory prob-
lems can occur while operating
this tool. Wear personal protective
equipment to reduce your risk from
these hazards.
If you are not experienced with
this type of tool, WE STRONGLY
RECOMMEND that you seek addi-
tional training outside of this man-
ual. Read books/magazines or get

Some workpieces are not safe to sand or
may require modification before they are
safe to sand. Before sanding, inspect all
workpieces for the following:
• Material Type: This tool is intended
for sanding painted or unpainted
metal, fiberglass, wood, and com-
posite surfaces.
• Foreign Objects: Fasteners, rivets,
clips, and other foreign objects are
often found in and around metal,
fiberglass, wood, and composite sur-
faces. While sanding, these objects
can become dislodged and hit the
operator, cause kickback, or cause
disc to fly apart, which could injure
operator, injure bystanders, or dam-
age workpiece surface. Always visu-
ally inspect your workpiece for these
items. If they cannot be removed, DO
NOT sand.
Workpiece Inspection Attaching/Removing
Sanding Discs
The Model T33306 is supplied with sand-
ing discs for use with the hook & loop
backing pad.
To attach/remove sanding disc:
1. DISCONNECT BATTERY FROM
TOOL!
2. Place tool on tool rest with backing
pad upright (see Figure 11).
Note: If D-handle is installed, disc can
be installed with tool on its side.
Figure 11. Tool placed on tool rest.
Tool
Rest
Only use 7" sanding discs that
are compatible with hook & loop
fasteners.

Model T33306 (Mfd. Since 11/22) -15-
3. Press disc onto hook & loop surface,
making sure edges align to avoid dam-
aging workpiece surface and backing
pad (see Figure 12).
Note: Make sure hook & loop surface
is free from dirt and other material
before attaching sanding disc.
4. To remove disc, peel away disc from
edge (see Figure 12).
The Model T33306 is a rotary sander/
polisher. When viewed from above, the
backing pad spins clockwise on a spindle.
This sander is suitable for moderate to
heavy material and defect removal, and is
typically used with multiple grits of sand-
paper discs.
Always test a small section of the surface
to judge the strength or sanding action of
a disc. Choosing a sanding disc depends
upon the amount of material that needs to
be removed, and the finish desired. There
are multiple grits from coarse to ultra-fine
to choose from. For best possible finish
results, work your way up from a coarse
grit to fine grit disc.
Make sure the area to be sanded is dry
and free of hazards. Wet surfaces can
affect the of life of the disc, and hazards
can damage the tool and lead to personal
injury. Vacuum or wipe workpiece surface
between grit changes to remove any dust
and unnecessary abrasives.
On flat surfaces, use long overlapping
strokes. Use a circular motion on curved
or angled sections.
Always hold the tool firmly with one hand
on the main handle and the other hand on
the D-handle.

6. Examine sanded surface.
— If results are satisfactory, repeat
Steps 2–5 over larger area.
— If results are unsatisfactory, repeat
Steps 1–5 and use either a less or
more abrasive sanding disc.
Figure 13. Sanding surface.
To perform a sanding operation:
1. Attach disc to backing pad (see
Attaching/Removing Sanding Discs
on Page 14).
2. Start tool and let motor reach full
speed.
3. Place disc on surface, press Speed
Selector button to increase sander
speed, if desired, then lightly move
sander around workpiece in long,
sweeping strokes (see Figure 13).
Note: Too much pressure, improper
motion, or leaving the tool running in
place too long can cause swirl marks
or lead to rapid removal of material.
Tip: Lift tool from surface often to
check workpiece and allow sawdust to
clear.

Model T33306 (Mfd. Since 11/22)-18-
The Model T33306 can be used to achieve
a high gloss shine on finished wood sur-
faces.
Allow your finish to cure thoroughly. The
general rule is that the longer the finish is
allowed to cure, the better the final result
will be.
Always follow manufacturer's instructions
on how to use their wax or polish product.
Before using the sander for polishing oper-
ations, use a fine grit of sandpaper or
steel wool to lightly roughen the surface.
This will remove any bumps or dust on the
workpiece surface.
Apply mineral spirits and wipe the
workpiece dry. This will remove the debris
created by the light sanding.
To polish a wood workpiece:
1. Attach pad or bonnet to backing pad
(see Installing/Removing Wool
Bonnet on Page 17).
2. Apply polish evenly on wood surface
(see Figure 16).
3. With hands firmly gripping tool, start
tool at lowest speed.
Note: Always use handles for proper
control.
4. Place tool lightly against surface of
wood (see Figure 17). Move tool slowly
and evenly, from side to side, slightly
overlapping on each pass. Continue
until most of polish has disappeared.
Note: Too much pressure, improper
motion, or stopping sander in one loca-
tion can cause swirl marks.
