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.

ation of power tools. Never operate under  
the influence of drugs or alcohol, when  
tired, or when distracted.  
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!  
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 12" 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 Replacement  
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.
