WARNING: Do not wear loose clothing, neckties, rings, bracelets, or other jewelry to get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair covering to contain long hair.
WARNING: Don't over reach. Keep proper footing and balance at all times. A rotating wheel or belt can catch an article
of clothing and cause personnel injury.
WARNING: 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.
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.
WARNING: Check damaged parts. Before further use of the grinder, a guard or other part that is damaged should
be carefully checked to assure that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.
WARNING: Use proper 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. Table 1 shows the correct wire size to use
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: Dust created during grinding, 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: Never leave grinder running unattended. Always turn power off after use.
Caution: Don't force grinder. 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 with care. Keep grinder clean for best and safest performance.
