Operating instructions for the Model 720 belt grinder
February 2007
Picture 1: Shown, a model 720 with optional 4 inch diameter wheel, variable speed, with remote control console. Note guard door is closed
and latched.
The model 720 belt grinder is a two wheel path belt grinder that uses a 2 x 72-inch continuous loop abrasive
belt. For maximum effectiveness, and operator safety use abrasive belts manufactured by well respected
abrasive manufacturers.
* Use abrasive belts that are the proper size and type for your machine.
* Do not use abrasive belts that are old and excessively worn.
• Do not use abrasive belts that use lap splice joints. This type of belt is prone to separate. It also
may tend to snag your work and create a safety hazard. It may also perform poorly.
The model 720 will accept front wheels (contact wheels) that are from 9/16 inch in diameter to 4 inches in
diameter. The belt width may be ½, 1, or 2 inches. The belt length is always 72 inches and the belt speed is
independent of the contact wheel size. Note that the front wheel attachment is secured to the machine probe
by two ¼-20 Allen cap bolts (picture 2). Loosen and remove these bolts to remove the adapter that secures
the wheel to the extension arm.
Prior to operating the model 720 please take time to do the following:
1. Insure that you have received all of the items that you ordered. Compare the packing slip with your
purchase order, and of course with the physical items received.
2. Verify that there is no obvious shipping damage. If shipping damage is discovered notify the freight carrier
of your intention to file a freight damage claim. They will assist you.
3. Verify that the AC power that is identified on the machine as received matches the AC power that you
intend to operate the machine with. Do not modify the machines wiring without first contacting your
distributor or Burr King manufacturing.
4. Do not modify or defeat any AC wiring safety feature. In example, do not remove the grounding pin on the
AC plug.
5. Verify that you have received a warranty card, parts lists, catalog, and Operator, and Operating Area
Safety Instructions.
6. Complete the warranty card and return it to Burr King Manufacturing.
7. Verify that the belt path guard is in place and that its door and latches are functional (see picture 1). Verify
that the pinch guard is in place and securely fastened by the two screws supplied (see picture 2).
