Operation; Operating Components; Causes Of Kickback - Hitachi C 10RJ Safety Instructions And Instruction Manual

English
DANGER:
Feed the workpiece into the saw blade or cutter only against the direction of rotation.
Feeding the workpiece in the same direction that the saw blade is rotating above the table
may result in the workpiece, and your hand, being pulled into the saw blade.
WARNING:
In the event of a power failure or when the tool is not in use, turn the switch OFF. This
action will prevent the tool from accidentally starting when power returns.
WARNING:
ALWAYS make sure your workpiece is not in contact with the blade before operating the
switch to start the saw. Blade contact could result in kickback or thrown workpiece.
WARNING:
To reduce the risk of accidental starting, ALWAYS make sure the switch is in the OFF
position before plugging saw into the power source.
WARNING:
DO NOT use blades rated less than the speed of this tool. Failure to heed this warning
could result in serious personal injury.
WARNING:
The operation of any power tool can result in foreign objects being thrown into the eyes,
which can result in severe eye damage. Always wear safety goggles or standard safety
glasses with side shields complying with United States ANSI Z87.1 before commencing
power tool operation.
WARNING:
Never operate the saw with the blade guard removed except
for dado and other non-through cuts. Reinstall the blade guard
immediately after finishing any non-through cut operations
which require removal of the blade guard. Failure to heed this
instruction could result in serious personal injury.

OPERATING COMPONENTS

• The upper portion of the blade projects up through the table and is surrounded by an insert called the
table insert. The height of the blade is set with a height adjusting handle on the height/bevel adjusting
handwheel. Detailed instructions are provided in this manual for the basic cut: cross cuts, miter cuts, bevel
cuts, and compound cuts.
• The rip fence is used to position workpiece for lengthwise cuts and used for extension table for large
workpiece cuts.
• It's very important to use the blade guard assembly for all through-cut sawing operations. The blade guard
assembly includes: riving knife, anti-kickback pawls, and blade guard.

CAUSES OF KICKBACK

Kickback can occur when the blade stalls or binds, causing the workpiece to be kicked back toward the
operator with great force and speed. If your hands are near the saw blade, they may be jerked loose from
the workpiece and come into contact with 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 work piece.
• Twisting the wood while making a cut.
• Failing to support the workpiece.
• 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.
