7. WHEEL REPLACEMENT
HOW TO ORDER REPLACEMENT WHEELS
The Piranha III replacement diamond wheels are available either directly through Diamond Ground Products
or through local distributors who sell our products. The part number to use when ordering are listed below in
the ‘”Piranha Grinder Accessories” Chart. These wheels are in stock for immediate delivery. In manufacturing
replacement wheels, a special process is used to bond the diamond to the wheel which makes these wheels last
as long as possible when used for grinding tungsten. Grinding wheels other than DGP wheels will not only offer
less longevity, but may be dangerous and may void the warranty on this equipment.
HOW TO INSTALL REPLACEMENT GRINDING WHEELS
Please use the following steps to remove and replace the Diamond Grinding wheels:
1. Turn the power off, unplug the electrical outlet, and wait until the motor has come to a complete stop.
2. Completely unscrew and remove Handle A (see picture at adjusting handles). Lift up and remove the Arm,
taking care not to lose the washer between the Arm and the Handle. Set them aside.
3. Unscrew the six thumbscrews on the wheel cover. Remove the Wheel Cover to fully expose the Wheel.
4. Using the supplied Allen Wrench, loosen the four screws on the front of the Grinding Disk.
5. Remove the old Wheel and mount the replacement wheel on the arbor.
6. Replace all of the other parts in reverse order the exact same methods you used to remove them.
** IMPORTANT ***
