• Keep visitors at a safe distance from work area.
• Keep children out of the workplace. Make workshop child-
proof. Use
padlocks, master switches or remove switch
keys to prevent any unintentional use of power tools.
TOOL SHOULD BE MAINTAINED
• Always unplug tool prior to inspection.
• Consult manual for specific maintaining and adjusting
procedures.
• Keep tool clean for safest operation.
• Remove adjusting tools. Form habit of checking to see
that adjusting tools are removed before turning machine
on.
• Keep all parts in working order. Check to determine that
the guard or other parts will operate properly and per-
form their intended function.
• Check for damaged parts. Check for alignment of moving
parts, binding of moving parts, breakage of parts, mount-
ing and any other condition that may affect a tool’s
operation.
• A guard or other part that is
damaged should be proper-
ly repaired or replaced. Do not perform makeshift
repairs. (Use the parts list to order replacement parts.)
KNOW HOW TO USE TOOL
• Use right tool for job. Do not force tool or attachment to
do a job for which it was not designed.
• Disconnect tool from power when changing grinding
wheels.
• Avoid accidental start-up. Make sure that the switch is in
the off position before plugging in.
• Do not force tool. It will work most efficiently at the rate
for which it was designed.
• Keep hands away from moving parts and grinding surfaces.
• Never leave a tool running unattended. Turn the power off
and do not leave tool until it comes to a complete stop.
• Do not overreach. Keep proper
footing and balance.
• Never stand on tool. Serious injury could occur if tool is
tipped over.
• Know your tool. Learn the tool’s operation, application
and specific limitations.
• Use recommended accessories. Use of improper acces-
sories may cause risk of injury to persons.
• Handle the workpiece correctly.
