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

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 acci­dents and injury.

Model T25942 (Mfd. Since 04/16) -1-

MENTAL ALERTNESS REQUIRED. Full
mental alertness is required for safe oper­ation 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
prevents an injury risk from unintended
startup or contact with live electrical com­ponents.

EYE PROTECTION.

approved safety glasses or a face shield

reduce the risk of eye injury or blindness
from flying particles. Everyday eyeglasses
are not approved safety glasses.

ELECTRICAL SAFETY. Tool plug must

in good work-

If at

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 opera­tion 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 con­nect 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 cov­ers reduce accidental contact with mov­ing parts or flying debris. Ensure they
are properly installed, undamaged, and
working correctly.

CHILDREN & BYSTANDERS. Keep chil­dren 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
ing condition. A tool that is improperly
maintained could malfunction, leading to
serious personal injur y or death. Only
have tool serviced by qualified service­personnel 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 dis­connecting 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 loca­tions. 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.

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

Additional Safety Instructions for Roll Sanders

PR OPE R AT TACHM ENTS . Only use

undamaged sanding/grinding/polish­ing attachments that are rated for the
spindle size of this tool and designed
for the intended use. Attachments that
do not properly fit on spindle could fly
apart or come loose from tool during use
and strike you, causing serious injury or
blindness.

ATTACHME NT S PEE D RAT I NG.
Attachments operated at a faster speed
than rated for may break or fly apart and
strike you with great force. Before mount­ing a new attachment, be sure the RPM
rating is equal to or higher than the speed
of this tool.

AVOIDING FIRE HAZARD. Do not use
near flammable/combustible materials.
Avoid overheating workpiece or sander to
reduce fire hazard.

CONTROLLING TOOL. Always use both
hands and maintain a firm grip on tool
during operations to prevent kickback
and avoid kickback-related injuries. Pay
special attention when working corners
and edges, as these operations have
greater tendency to produce kickback/
loss of control.

TRANSPORTING TOOL. Always turn tool
OFF and disconnect it from power while
carrying tool at your side. Otherwise,
accidental startup of tool could cause
spinning attachment to snag clothing,
pulling tool toward your body, causing
injury.

HAND/ATTACHMENT CONTACT.
Spinning attachments have the capability
of removing a lot of skin fast. Keep a firm
grip on the tool and position your hands
at a safe distance from attachment during
operation. Avoid wearing gloves, as they
may get caught in spinning attachment
and cause even more serious entangle­ment injuries.

COMPLETING OPERATION. Always
wait for tool to come to a complete stop
before setting it down. Otherwise, spin­ning attachment may grab surface or
other object and pull tool out of your con­trol, causing personal injury or property
damage.

TOOL VENTILATION. Inspect and clean
tool air vent on a regular basis. Failure to
do so can cause overheating of motor,
tool failure, and electrical hazards.

Tool Operation Tips

In addition to the safety instructions in this
manual, the most important safety con­sideration is to use common sense at all
times. What may be okay in one situation
may not be safe in another.

Here are some tips to keep in mind
while using this tool:

• Always be sure the attachment is
secured on the spindle by tightening
the spindle flange screw.

• Always keep one thumb poised over
the ON/OFF switch during operations,
in case you need to quickly turn tool
OFF.

• Work against the direction of spindle
rotation to maintain optimum control of
tool. Working in the same direction as
the rotation can cause the tool to lunge
or fly out of your hands.

• Concentrate on the task at hand. STOP

If you have never used this type
of tool or equipment before, WE
STRONGLY RECOMMEND that you
read books, trade magazines, or get
formal training before beginning any
projects. Regardless of the content
in this section, Grizzly Industrial
will not be held liable for accidents
caused by lack of training.

Removing/Installing

Attachments

Tool Needed:

Hex Wrench 4mm ..................................... 1

To remove/install attachment:

The Model T25942 Pro Sanding Roller
comes with three sanding attachments: a
25⁄16" x 7⁄16" 80-Grit flap wheel, a 25⁄16" x 23⁄8"
80-Grit flap wheel, and a sanding drum with
a 13⁄4" x 23⁄8" 80-Grit sanding sleeve.

Flap wheels are composed of many sand­ing flaps that can follow the contours of a
workpiece. They are well suited for light
sanding and can achieve a more "feath­ered" result. Examples:

• Sanding thin layers of paint

• Sanding radiused edges and corners

• Light, touch-up sanding

Sanding drums with sleeves are rigid and
less "forgiving." They are well suited for
aggressive sanding and produce a more
precise, defined edge. Examples:

• Sanding paint/glue build-up

• Sanding sharp edges and corners

• Aggressive, rough sanding

1. DISCONNECT TOOL FROM POWER!

2. Press spindle lock button to prevent

spindle rotation during next step (see

Figure 3).

3. Remove spindle flange screw (see
Figure 3), and remove attachment.

4. Slide replacement attachment onto
spindle (see Figure 3).

5. Thread spindle flange screw into end

of spindle, then press spindle lock
button as you fully tighten screw (see
Figure 3).

Carbon Brushes

The Model T25942 is equipped with a pair
of carbon brushes that are NOT designed
to be user-serviceable or replaceable. The
brushes shown in the parts breakdown are
for reference purposes only and are NOT
available for purchase.

As with all similarly constructed tools, the
carbon brushes are considered to be a
regular "wear" item. In other words, they
will eventually wear out and will do so in
direct proportion to overall tool use (or
abuse). As such, brush wear is NOT cov­ered under warranty. However, when used
with care, this tool will provide an extended
level of service and brush wear will be
relatively slow.
