WARNING:
When starting a grinder for the first time, or after installing a replacement wire 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 a wire wheel can disintegrate if it received
damage during shipping or handling.
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.
3.
Mount grinder-buffer on solid bench. The grinder-buffer must be securely bolted to a
rigid mounting surface. If a pedestal is used, first bolt pedestal securely to floor and then
bolt grinder-buffer to pedestal.
4.
Check grinder-buffer nameplate to make certain the rating is correct for the power
source, voltage and frequency.
