SECTION 1: SAFETY
For Your Own Safety Read Instruction Manual
Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazard-
ous conditions. This manual uses a series of symbols and signal words which
are 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.
Indicates an imminent 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 infor-
mation about proper operation of the equipment.

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!
DISCONNECT POWER FIRST. Always
disconnect tool from power supply
BEFORE making adjustments, chang-
ing tooling, or servicing machine. This
prevents an injury risk from unintended
startup or contact with live electrical com-
ponents.
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.
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.

Power Connection
Serious injury or death can result
from using this machine BEFORE
understanding its controls and
related safety information. DO NOT
operate, or allow others to oper-
ate, machine until the information is
understood.
After you have completed all previous
setup instructions, the machine is ready to
be connected to the power supply.
To avoid unexpected startups or property
damage, use the following steps whenever
connecting or disconnecting the machine.
Connecting Power
Test Run
1. Turn machine power switch OFF.
2. Insert power cord plug into a matching
power supply receptacle. Tool is now
connected to power source.
To test run machine:
1. Clear all setup tools away from
machine.
2. Remove collet nut and collet.
3. Set variable-speed knob to lowest set-
ting.
4. Connect machine to power supply.
5. Turn machine ON, verify motor opera-
tion, and then turn machine OFF.
Tool should run smoothly and without
unusual problems or noises.
Figure 3. Connecting power.
Disconnecting Power
1. Turn machine power switch OFF.
2. Grasp molded plug and pull it com-
pletely out of receptacle. Do not pull
by the cord as this may damage wires
inside.

SECTION 4: OPERATIONS
4. Insert bit shank into collet.
Installing Bits
The Model T10828 uses bits and cutters
with a ⁄8" diameter shaft. See the Grizzly
catalog or website for a complete listing of
available bits and accessories.
Note: At least 1⁄2" of bit shank should be
mounted into end of collet.

5. Hand-tighten collet nut while pressing
spindle lock button to secure bit.

6. Tighten ⁄3 of a turn with collet wrench.
DO NOT use bits or cutters with a
cutting surface larger than 1". The
bit could break apart under the
stresses of high speed use caus-
ing serious personal injury.
DO NOT over tighten.
Failure to wear safety glasses
while operating the grinder could
cause serious personal eye injury.
To install a bit:
1. DISCONNECT TOOL FROM POWER!
Operating Rotary Tool
2. Press spindle lock and rotate collet nut
until spindle locks (see Figure 5).
The Model T10828 is best suited for high-
RPM, low-torque applications. Most opera-
tions performed with the tool will perform
best at higher RPM settings; however,
slower RPM settings are ideal when work-
ing with plastics that melt easily.
3. Loosen collet nut by turning counter-
clockwise.
NOTE: DO NOT completely remove
collet nut from shaft.
High RPM Uses
High RPM's are best for general carving,
cutting, routing, and grinding. The grinder
removes material quicker at higher RPM's.
Collet Nut
Low RPM Uses
Low RPM's are best for grinding and cut-
ting materials that have low melting points.
Plastics in particular often melt from the
heat generated by high-speed bits. Low
RPM's are also best for polishing and buff-
ing with the felt accessories included.

light pressure.
Note: Always test bit and RPM com-
bination on a scrap piece of material
similar to workpiece.
3. Pull inner spindle partially out of flex
shaft (see Figure 6).
4. Insert inner spindle into rotary tool
collet, then tighten collet nut, as
described in Steps 5–6 on Page 8.
Use low RPM settings when work-
ing with plastics or other materials
with low melting points. Melted
plastics can liquefy, be thrown into
the air, and stick to the operator,
causing serious personal injury.
5. Thread flexible shaft plastic locking ring
onto rotary tool attachment threads.
6. Insert shank of tool bit into collet as
shown in Figure 7, then slide down flex
shaft locking sleeve and tighten collet.
Installing Flex Shaft
The flex shaft allows the user to get into
tight spaces and is easier to control—
more like a pencil. DO NOT operate the
flex shaft with sharp bends.
Note: Hold flex shaft firmly when start-
ing rotary tool.
Tool Bit
Shaft
To install flex shaft:
1. DISCONNECT TOOL FROM POWER!
2. Loosen collet nut and remove plastic
locking ring on rotary tool (see Figure 1
on Page 5) to expose shaft attachment
threads, as shown in Figure 6.

SECTION 6: MAINTENANCE
2. Apply a thin film of lubricant on inner
spindle.
Note: Too much lubricant can become
!
messy and possibly get on your
workpiece. DO NOT use automotive
grease; it is too thick.
3. Re-install inner spindle into flex shaft.

Carbon brush life is 500–2000 hours,
depending on the nature of use. Always
replace both brushes at the same time.
before servicing, adjusting, or doing
maintenance to reduce the risk of
accidental injury or electrocution.
To replace carbon brushes:
Schedule
1. Use small flathead screwdriver, includ-
ed in toolbox, to remove caps from
sides of motor housing (see Figure 8).
For optimum performance from your
machine, follow this maintenance sched-
ule and refer to any specific instructions
given in this section.
Note: Brushes are spring loaded; take
care when removing caps.
Daily Check
•
Wipe motor housing, flex shaft, and tool
bits with dry cloth or blow off dust and
debris with compressed air( be sure to
wear a respirator while doing this.).
•
Check for damage to bits, cords, or the
housing.
Lubrication
Figure 8. Replacing 1 of 2 carbon
brushes.
The flex shaft needs to be lubricated with
a light lithium lubricant or machine oil after
25-30 hours of use.
2. Install new brushes.
To lubricate flex shaft:
3. Re-install brush cap. Run tool for 5
minutes to seat brushes before using it
on a workpiece.
1. Remove inner spindle.
