SAFETY NOTICE
Continued
WARNING:
When starting a grinder for the first time, or after installing a replacement belt or wire
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 a wire wheel can disintegrate if it received
damage during shipping or handling.
WARNING:
Use proper grounded extension cord. Make sure your extension cord is in good condition.
When using an extension cord, be sure it is rated for the voltage and current rating of your
product. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating. Use the correct wire size depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The smaller the AWG gauge number, the heavier
the cord.
WARNING:
Always wear a dust mask to prevent dust inhalation when adequate ventilation or extraction
is not available.
WARNING:
Dust created during grinding, buffing, sawing, power sanding, drilling, and other activities
may contain chemicals known to the State of California to cause cancer, birth defects or
other reproductive harm.
WARNING:
Keep children and visitors away. Remove starter keys turn off master switches. Padlock
equipment or work area when not in use.
WARNING:
Don't over reach. Keep proper footing and balance at all times. A rotating wheel can catch
an article of clothing and cause personnel injury.
WARNING:
Never leave grinder-buffer running unattended. Always turn power off after use.
Caution:
Don't force grinder-buffer. It will do the job better and safer at the feed rate for which it
was designed.
Caution:
Use right tool. Don't force tool or attachment to do a job for which it was not designed.
Caution:
Maintain grinder-buffer with care. Keep grinder-buffer clean for best and safest
performance.
