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 wheels 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. A damaged grinding wheel can disintegrate causing a
hazard for nearby personnel. After connecting grinder to power source, turn switch on. Tool
grinder should come up to speed smoothly and without vibration. If grinder does not, shut off
immediately, remove from power source and determine reason. Make necessary corrections
before operating grinder.
As grinding wheel wears, maintain the maximum clearance of
1
/
8
″
between table and rim face
of the wheel. Suggested clearance is
1
/
16
″
when making adjustments.
Grind on rim face of wheel only.
Maintenance
WARNING:
Prevent electrical shock hazard and accidental machine operation. Always disconnect
grinder from the power source before servicing, changing accessories (such as wheels,
tool rest, spark arrestor, etc.) or before performing maintenance.
WARNING:
Never install a wheel that is damaged, such as a chip or crack on any surface. A damaged
wheel can disintegrate while rotating at a high RPM or when work is placed against the
wheel. This can severely harm the operator or others in the area.
Replace worn grinding wheel as necessary. When replacing a worn wheel, remove all
grinding dust from wheel guard.
Motor and pulley bearings are lubricated for life and do not require additional lubrication.
Replacement wheels may be purchased directly from your local industrial supply dealers,
abrasive dealers, tool dealers, etc.
Remove grinding dust to prevent accumulation.
Replace damaged parts immediately to maintain safety of machine.
