摘要： A portable cutting machine includes an electric motor, a base having a lower surface coming in contact with a workpiece, a cutting machine body coupled to an upper surface of the base and accommodating the electric motor, a handle on a rear portion of the cutting machine body and at least partially rearward from a rear end of the base, a blade on a left or a right of the handle and rotatable with the electric motor, and a battery attachment portion receiving a battery pack for powering the electric motor. The battery attachment portion includes an opening directed away from the blade, an attachment surface standing with respect to the base, and a rail receiver extending in the attachment surface to receive the battery pack in a detachable manner. The battery pack on the rail receiver extends laterally over a center plane of the handle.

摘要： A portable cutting apparatus includes a base, a main body and a cover both on a second side of the base. The main body is displaceable relative to the base and the cover between a first position, where a blade is entirely contained in the cover, and a second position, where the blade protrudes to a first side opposite the second side beyond the base. The cover includes a cover main body, and an auxiliary cover located in proximity to the base and movable relative to the cover main body. The main body portion and the cover main body are tiltable about a first axis located on the first side of the base. The auxiliary cover is at least partially tilted about a second axis located on the second side of a surface of the base on the first side in conjunction with the tilting of the cover main body.

摘要： A circular saw including a base defining a longitudinal axis. The circular saw further includes a front bevel angle adjustment bracket proximate a front end of the base and a rear bevel angle adjustment bracket proximate a rear end of the base. The circular saw further includes a saw unit coupled to the base via the front bevel angle adjustment bracket and the rear bevel angle adjustment bracket. The circular saw further comprises a first fastener extending through a first elongated slot in one of the base or the front bevel angle adjustment bracket and a second fastener extending through a second elongated slot in one of the base or the rear bevel angle adjustment bracket. Each of the first and second elongated slots extends along a lateral axis oriented transverse to the longitudinal axis of the base to permit lateral adjustment of the saw unit relative to the base.

摘要： Apparatus, systems, and/or methods for adjusting belt tension in a material removal machine are disclosed. In some examples, the material removal machine includes a material removal tool secured on a spindle. A spindle pulley may be secured to the spindle, such that rotation of the spindle pulley causes the material removal tool to be rotated via the spindle. The material removal machine may further include a movable hub that retains the spindle, such that movement of the hub translated into movement of the spindle. Because the spindle pulley is securely attached to the spindle, movement of the hub may translate into movement of the spindle pulley. This movement of the spindle pulley may change a distance between the spindle pulley and an actuator pulley, thereby changing the tension in a belt connecting the spindle pulley and the actuator pulley.

摘要： A power tool, such as a cast saw is disclosed. The cast saw is equipped with at least one thermocouple and and/or at least one infrared detector that measure the temperature of the cutting blade on the cast saw or the area in the cast immediately surrounding the cutting blade. The cast saw is also equipped with at least one LED that can alert a user of the cast saw when blade or the area in the cast immediately surrounding the blade is approaching or has reached a temperature that may burn a patient. Also disclosed is a shroud for the cutting blade of the cast saw. The shroud not only surrounds at least part of the blade but also houses the thermocouple or infrared detector and the LEDs(s). A method of operating the cast saw to cut a cast off of a patient is also disclosed.
