BE PREPARED FOR JOB
1. Wear proper apparel. Do not wear
loose clothing, gloves, neckties, rings,
bracelets or other jewelry which may
get caught in moving parts of
machine.
7. Keep children out of workplace.
Make workshop childproof. Use padlocks, master switches or remove
switch keys to prevent any unintentional use of power tools.
4. Do not force a tool. It will work
most efficiently at the rate for which
it was designed.
TOOL SHOULD BE MAINTAINED
6. Never leave tool running unattended. Turn the power off and do not
leave tool until it comes to a complete stop.
1. Always unplug tool prior to inspection.
2. Wear protective hair covering to contain long hair.
2. Consult manual for specific maintaining and adjusting procedures.
3. Wear safety shoes with non-slip soles.
3. Keep tool lubricated and clean for
safest operation.
4. Wear safety glasses complying with
instructions.Everyday glasses have
only impact resistant lenses.
They are NOT safety glasses.
5. Wear face mask or dust mask if operation is dusty.
6. Be alert and think clearly. Never operate power tools when tired, intoxicated or when taking medications that
cause drowsiness.
PREPARE WORK AREA FOR JOB
1. Keep work area clean. Cluttered work
areas invite accidents.
2. Do not use power tools in dangerous
environments. Do not use power
tools in damp or wet locations. Do
not expose power tools to rain.
3. Work area should be properly lighted.
4. Proper electrical receptacle should be
available for tool. Three-prong plug
should be plugged directly into properly grounded, three-prong receptacle.
5. Extension cords should have a
grounding prong and the three wires
of the extension cord should be of
the correct gauge.
6. Keep visitors at a safe distance from
work area.
4. Remove adjusting tools. Form habit
of checking to see that adjusting
tools are removed before switching
machine on.
5. Keep all parts in working order.
