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 grinding wheels can disintegrate if they have
received damage during shipping or handling.
3.
Mount grinder on solid bench. The grinder must be securely bolted to a rigid mounting
surface. If a pedestal is used, first bolt pedestal securely to floor and then bolt grinder to
pedestal.
4.
Check grinder 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.
Adjust spark arrestor for approximately
1
/
16
″
clearance between it and grinding wheel.
Maintain 1/8
″
or less clearance between spark arrestor and wheel as wheel wears.
6.
Adjust angle of tool rest on support to desired position and tighten nut securely. Adjust
tool rest support on guard to attain approximately
1
/
16
″
clearance between tool rest and
grinding wheel and tighten nut securely. Maintain
1
/
8
″
or less clearance between tool
rest and wheel.
7.
Adjust eyeshield to position aligning center of eyeshield in line of sight to tool rest.
