Installation When you receive your unit, there are several things you should do immediately.
1. Observe the condition of the shipping container and report any damage immediately to
the commercial carrier that delivered the product.
2. Verify that the part number you received is the same as the part number listed on your
purchase order.
WARNING: When starting a grinder for the first time, or after installing a replacement grinding wheel,
it is most important that the operator stand aside for at least one minute of rotation at full
speed. This is the correct practice since debris in the wheel may be thrown out during the
first moments the machine is in operation.
3. Mount buffer on solid bench. The buffer must be securely bolted to a rigid mounting
surface. If a pedestal is used, first bolt pedestal securely to floor and then bolt buffer to
pedestal.
4. Check buffer nameplate to make certain the rating is correct for the power source,
voltage and frequency. See electrical and grounding instructions for electrical service
connection.
5. Install soft cloth buffing wheel (see Typical Buffer Figure)
a. Remove arbor nut, spacer and outer wheel flange.
b. Place the buffer wheel on the arbor.
c. Install the outer wheel flange, spacer and arbor nut.
d. The arbor nut should be tightened just enough to prevent the wheel slipping on the
arbor and the vinyl arbor nut cover must be in place.
When starting buffer for the first time or after installing replacement wheel, it is most important
that the operator stand aside for at least one minute. Debris in the wheel may be thrown out
during the first moments the machine is in operation.
Electrical Instructions
Single phase buffers are equipped with cord and grounding type plug for 115 volts. To use
with a different voltage, see instructions provided to make wiring changes. All attachment
plugs and any receptacles must be replaced with devices rated for the voltage for which the
buffer is reconnected. Table 1 indicates the minimum wire size. Be sure to comply with NEC
and local wiring codes.
