摘要： Two 18V-type rechargeable batteries (31 and 31) are attached in series so as to allow a 36V-type tabletop cutting device (C1) to be utilized. By utilizing the 18V batteries which are highly prevalent for electric tools, it is possible to use the 36V-type tabletop cutting device (C1) as well as to reduce costs for the batteries.

摘要： A chop saw has a base assembly, a support housing connected to the base assembly, a saw assembly pivotally connected to the support housing allowing the saw assembly to be pivoted downwardly towards the base assembly for conducting a cutting operation on a workpiece. The saw assembly has a motor, a blade driven by the motor and an upper blade guard for covering an upper portion of the blade. A sensor assembly senses a position of the saw assembly relative to the workpiece and/or the support housing. A controller receives a signal an input representative of the position of the saw assembly from the sensor assembly and controls the motor according to such signal.

摘要： A saw for performing chop cuts has a base, a cutting unit, and a pivot joint pivotally mounting the cutting unit to the base to enable the cutting unit to pivot towards or away from the base to perform chop cuts. The pivot joint has a cup-shaped section having an open end, a cap rotatably mounted on the open end of the cup-shaped section to form a sealed enclosed space within the cup-shaped section and cap, and a spring located inside of the sealed enclosed space. The spring is connected between the cup-shaped section and the cap. The spring applies a rotational biasing force between the cup-shaped section and the cap to urge relative rotation movement between the two.

摘要： A cutting machine can include a cutting machine body that is movably supported above a table and capable of vertical movement, the cutting machine body can be positioned at an upward waiting position and a lower end position. The cutting machine body can include an auxiliary cover positioned around a portion of a blade and including a projection. When in the upward waiting position the auxiliary cover is not able to move upward because of the position of the projection, and in the lower end position the auxiliary cover is able to move upward.
