Secure work. Use clamps to secure the work piece when practical. It’s safer than using
your hand and it keeps hands away from wheel.
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.
WARNING:
Always have the grinder switch in the “OFF” position when changing the position of the
pivot arm. Do not attempt to change the pivot arm position while the belt is moving as this
will create a hazardous situation for the operator.
