before beginning any work. Serious
personal injury may result if safety
or operational information is not

Installing Bits
The Model H8210 uses bits with a 13/32"
(10mm) diameter shaft. See the Grizzly
catalog or www.grizzly.com for a complete
listing of available bits and accessories.
3. Insert the bit by bending the retainer
spring out of the way of the cylinder
bore and slide the bit in as shown in
Figure 2.
Note: If you have difficultly bend-
ing the retainer spring to fit the bit,
remove the spring and insert the bit
into the spring prior to threading it on
the hammer.
Figure 2. Bit installation.
Like all tools there is potential danger
when operating this tool. Accidents
are frequently caused by lack of
familiarity or failure to pay attention.
If normal safety precautions are
overlooked or ignored, serious
personal injury may occur.
4. Relax the retainer spring so the "U" sits
in front of the bit flange to hold the bit
in place, as shown in Figure 3.
