Operation
WARNING:
Do not operate this grinder-buffer until you are sure that you are completely familiar with
the safe operation of the grinder-buffer, 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 seek expert advise if you do not
understand any procedure or operation concerning this grinder-buffer or this manual.
WARNING:
Always use safety glasses with side shields (or full face shield) when operating grinder.
Do not use ordinary eyeglasses. Also use face or dust mask if cutting operation is dusty.
WARNING:
When starting a grinder for the first time, or after installing a replacement wheel or belt, 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 belts and wire wheels can disintegrate if they
have received damage during shipping or handling.
WARNING:
Be sure the system is properly grounded before applying power. Do not apply power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. Follow the National Electrical Code (NEC) and local codes for the safe installation
of this equipment.
