sion cord is in good condition. Con-  
ductor size should be in accordance  
with the chart below. The amperage  
rating should be listed on the motor  
or tool nameplate. An undersized  
cord will cause a drop in line voltage  
resulting in loss of power and over-  
heating. Your extension cord must  
also contain a ground wire and plug  
pin. Always repair or replace exten-  
sion cords if they become dam-  
aged.

OPERATIONS  
Charging the Battery  
Installing Bits  
The Model H6156 is not shipped fully  
charged. It will have to be charged for 3  
hours before use. DO NOT charge lon-  
ger than this or damage to the battery  
may occur!  
The Model H6156 uses bits and cutters  
with an 18" diameter shaft. See the Grizzly  
catalog or website for a complete listing of  
available bits and accessories.  
To charge the battery:  
1. Remove the battery from the mini

grinder.  
2. Insert the battery into the charger as  
shown in Figure 2.  
To install a bit:  
1. Unplug the tool from the power  
source!  
2. Depress the collet lock shown in Figure

mounted into the end of the collet.  
4. Rotate the collet nut while depressing  
the collet lock to secure the bit. Only  
tighten 1/3 of a turn with the collet  
wrench.  
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.  
Failure to wear safety glasses while  
operating the grinder could cause  
serious personal eye injury.  
Use low RPM settings when work-  
ing with plastics or other materi-  
als with low melting points. Melted  
plastics can liquefy, be thrown into  
the air, and stick to the operator,  
causing serious personal injury.  
Using The Grinder  
The Model H6156 is best suited for high  
RPM, low torque applications.  
Always test the bit and RPM combination  
on a scrap piece of material similar to the  
workpiece. Trial and error is the best way  
to determine the ideal setup.  
To use the grinder:  
1. Grasp the grinder with a secure grip.  
2. Rotate the speed lever to turn ON the  
mini grinder.  
3. Adjust the speed lever to change the  
RPM.  
4. Firmly grasp the grinder and ease it  
against the workpiece using light pres-  
sure.

Installing the Flashlight Base  
The flashlight base will give you the extra  
light that you need in low light situations.  
Daily Maintenance  
These items should be done after each  
use.  
To install the flashlight base:  
1. Unplug the tool from power!  
2. Remove the collet shield.  
1. Wipe the motor housing and tool bits  
with a dry cloth or blow off dust and  
debris with compressed air.  
2. Check for damage to bits, cords, or  
the housing.  
3. Screw the flashlight base onto the mini  
grinder in place of the collet shield.  
4. Turn the flashlight base ON/OFF with  
the small switch on the face of the  
flashlight base as shown in Figure 4.
