These tools are used
for crosscutting, mitering and beveling wood,
non-ferrous metals, and plastics. They cut through the workpiece at a
predetermined angle or miter. Some also can cut at a beveled angle.
Always wear safety goggles
or safety glasses with side shields
complying with current national standard, and a full face shield when
needed. Use a dust mask in dusty work conditions. Wear hearing
protection during extended periods of operation.
Do not wear gloves, loose
clothing, jewelry or any dangling objects that
may catch in rotating parts or accessories. Tie back long hair.
Because of the downward
cutting motion, your safety requires that you
stay very alert to keeping hands and fingers away from the path that the
blade travels.
Be sure all guards are
in place and working. If a guard seems slow to
return to its normal position or "hangs up," adjust or repair it immediately.
Be alert at all times-especially during repetitive, monotonous operations.
Don't be lulled into carelessness due to a false sense of security.
Blades are extremely unforgiving. Clean the lower guard frequently to
help visibility and movement. Unplug before adjustment or cleaning.
Use only recommended
size and RPM rated blades.
Abrasive cut-off wheels
should not be used on miter saws. Miter saw
guards are not appropriate for abrasive cut-off wheels.
Remember that loose blades
can fly off. Regularly check and tighten
the blade and blade attachment mechanism.
When installing or changing
a blade be sure the blade and related
washers and fasteners are correctly positioned and secured on the
saw arbor.
To avoid loss of control
or placing hands in the path of the blade, hold
or clamp all material securely against the fence when cutting. Do not
perform operations freehand.
Never cut small pieces.
Support long material at the same height as the
saw table.
Never place your hands
or fingers in the path of the blade, or reach in
back of the fence. It's hazardous to do so. Do not cross arms or hands
in front of blade to secure workpiece. Use clamps, if necessary. Saw
blades coast after being turned off-use the brake if one is provided. To
avoid contact with a costing blade do not reach into cutting areas until
the blade comes to a full stop.
After completing a cut,
release the trigger switch and allow the blade to
come to a complete stop as mentioned, then raise the saw blade from
the workpiece.
Miter saws have spring
loaded saw heads to return the saw head to its up
position. Adjust, repair, or replace the spring mechanism if the saw head
does not automatically return to its up position when released. Hold or
clamp the work firmly against the fence on the sawed end. Lock the miter
saw and blades in the down position during transport or when not in use.
ABRASIVE
CUT-OFF MACHINES
Although similar to miter saws in operation (see chapter on Miter Saws),
abrasive cut-off machines are designed to crosscut ferrous metal. The
wheel is made of abrasive materials held together with special resins.
The wheel grinds through the metal rather than cutting with teeth.
Accordingly, some special safety considerations come into play when
suing abrasive cut-off machines.
It is important to choose
the proper cut-off wheel for the material and
type of cutting you plan to do. All cut-off wheels have a maximum safe
speed rating. Only use wheels whose rating exceeds the operating speed
of your machine. Make sure the wheel is undamaged and properly aligned.
With the power head all the way down, hand spin the wheel and check
for clearance.
Make sure the wheel and
arbor collars are clean, and the collars'
recessed slides are facing the wheel.
When cutting any metals,
sparks or hot fragments could cause a fire.
Do not cut near flammable materials.
Always use the vise provided
with abrasive cut-off machine. Any
movement of your workpiece can cause the wheel to break and throw
portions of the wheel.
When beginning a cut
with the saw, care should be exercised not to
bump or slam the wheel into the work. Once the cut is started, continue
the cut with a smooth, even stroke. The faster a cut is made, the less
heat is created in the workpiece. This helps prevent discoloring and
prolongs wheel life. Cut with the maximum force that doesn't overload
the motor.
NOTE: Never replace the
abrasive wheel with a toothed blade. There will
be no excuse for a claim that the instructions invite this king of
misinterpretation as to the purpose of the tool.
