Operation
WARNING: Do not operate this grinder until you are sure that you are completely familiar with the safe
operation of the grinder, all accessories and safety equipment. Improper use can lead to
severe injury. This manual defines proper use of this equipment. Before using this
equipment for any other use, please consult Baldor. Contact Baldor if you do not
understand any procedure or operation concerning this grinder or this manual.
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.
Check that the On–Off switch is in the “OFF” position, and the grinding wheel and wheel
move freely. When starting the grinder for the first time or after replacing a wheel, it is
important that the operator stand aside for at least one minute of operation at speed. This will
ensure that operation will be safe from debris. After connecting grinder to power source, turn
switch on. Grinder should come up to speed smoothly and without vibration. If grinder does
not, shut grinder off immediately and determine reason.
As grinding wheel wears, maintain 1 /
8
″
or less clearance between tool rest and grinding wheel
and spark arrestor and grinding wheel.
Grind on grinding face (periphery) of wheels only.
