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.
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:
Unsuitable accessories or attachments added to this machine can create hazards. Baldor
accessories are specifically designed to be used with this grinder. Use accessories or
attachments only in the proper intended manner. Accessories or attachments obtained
from another source may cause hazards. Consult the manufacturer before use.
WARNING:
Keep guards in place and in working order. Guards are design to prevent injury. Never
operate this equipment if a guard is damaged, missing or improperly installed.
WARNING:
Remove adjusting keys and wrenches from this product after use. Check to see that keys
and adjusting wrenches are removed from grinder before turning it on. Projectiles can
cause severe injury to yourself or others.
WARNING:
Keep work area clean and well lighted. Clutter and poor lighting invites accidents.
WARNING:
Don’t use in dangerous environment. Don’t use grinders in damp or wet locations, or
expose them to rain. Electrical shock can cause serious or fatal injury. Follow the
National Electrical Code (NEC) and local codes for the safe installation of this equipment.
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.
