Operation - RIDGID R4520 Manual Del Operador

OPERATION

WARNING:
Do not allow familiarity with tools to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict serious injury.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
WARNING:
Do not use any attachments or accessories
not recommended by the manufacturer of this
tool. The use of attachments or accessories not
recommended can result in serious personal
injury.
WARNING:
Although many of the illustrations in this manual
are shown with the blade guard removed for
clarity, do not operate the saw without the blade
guard unless specifically instructed to do so.
WARNING:
The table saw must be mounted to a firm
supporting surface, such as a workbench or
leg stand that positions the saw at waist height.
Many illustrations in this manual are shown with
the saw unmounted for clarity.
APPLICATIONS
You may use this tool for the purposes listed below:
 Straight line cutting operations such as cross cutting,
ripping, mitering, beveling, and compound cutting
 Dado or molding cuts with optional accessories
 Cabinet making and woodworking
NOTE: This table saw is designed to cut wood and wood
composition products only.
BASIC OPERATION OF THE TABLE SAW
The 3-prong plug must be plugged into a matching outlet
that is properly installed and grounded according to all local
codes and ordinances. Improper connection of the equipment
can result in electric shock. Do not modify the plug; if it
will not fit the outlet, have the correct outlet installed by a
qualified electrician. Refer to the Electrical section earlier in
this manual.
CAUSES OF KICKBACK
Kickback can occur when the blade stalls or binds, kicking
the workpiece back toward you with great force and speed. If
your hands are near the saw blade, they may be jerked loose
from the workpiece and may contact the blade. Obviously,
kickback can cause serious injury, and it is well worth using
precautions to avoid the risks.
Kickback can be caused by any action that pinches the blade
in the wood, such as the following:
 Making a cut with incorrect blade depth
 Sawing into knots or nails in the workpiece
 Twisting the wood while making a cut
 Failing to support work
 Forcing a cut
 Cutting warped or wet lumber
 Using the wrong blade for the type of cut
 Not following correct operating procedures
 Misusing the saw
 Failing to use the anti-kickback pawls
 Cutting with a dull, gummed-up, or improperly set blade
AVOIDING KICKBACK
 Always use the correct blade depth setting. The top of
the blade teeth should clear the workpiece by 1/8 in. to
1/4 in.
 Inspect the work for knots or nails before beginning a
cut. Knock out any loose knots with a hammer. Never
saw into a loose knot or nail.
 Always use the rip fence when rip cutting. Use the miter
gauge when cross cutting. This helps prevent twisting
the wood in the cut.
 Always use clean, sharp, and properly-set blades. Never
make cuts with dull blades.
 To avoid pinching the blade, support the work properly
before beginning a cut.
 When making a cut, use steady, even pressure. Never
force cuts. Do not release the workpiece until you have
pushed it completely past the blade.
 Do not cut wet or warped lumber. The workpiece must
have a straight edge for it to be guided along the rip fence.
 Use extra caution when cutting some prefinished or composition wood products as the anti-kickback pawls
may not always be effective.
 Always guide your workpiece with both hands or with
push sticks and/or push blocks. Keep your body in a
balanced position to be ready to resist kickback should
it occur. Never stand directly in line with the blade.
 Use of a featherboard will help hold the workpiece securely
against the saw table or fence.
 Clean the saw, blade guard, under the throat plate, and
any areas where sawdust or scrap workpieces may gather.
