A material processing system includes: an offsetter configured to receive a stack of material and including a lifting bar configured to lift a portion of the stack of material; and a processing station operably connected to the offsetter. A method of processing a material includes: loading a stack of material on an offsetter, the stack of material including a first portion and a second portion, the first portion positioned above the second portion and separated from the second portion by at least one cross tie, the stack of material including a first end and a second end distal from the first end; lifting the second portion away from the first portion by a lifting bar of the offsetter pushing upward on the second end; and removing the cross tie.

The present invention is a circular saw holder. In an embodiment, the circular saw bracket is provided with a ledge protruding from the body of the bracket. The ledge is further provided with a lip. The configuration allows the upper blade guard of a circular saw to rest on the ledge, while the lip engages the inside surface of the blade guard, preventing the saw from falling off the bracket. In an embodiment, through holes in the body allow the bracket to be mounted to a surface using screws.

A device for cutting a length of pipe includes a clamp portion for clamping around a length of pipe and a bow moveable with respect to the clamp portion that retains a loop of diamond embedded wire. The device further includes a feed for driving the bow with respect to the clamp portion and a detector for detecting bending of the wire and a control responsive to the detector for controlling feed rates. The device is made of modular parts and has synchronizing arms for clamping around a length of pipe. In one embodiment, the wheels are retained in enclosures with slots through which the cutting wire passes.

A power tool arrangement includes a frame having an outlet. A power tool is coupled to the frame and includes a movable working element configured to engage a work piece. A hose includes first and second opposite ends and a biasing device configured to bias the hose into a longitudinally compressed position. The first end is coupled to the outlet. The second end is coupled to the working element such that the second end follows the movement of the working element and the hose thereby moves between the longitudinally compressed position and a longitudinally expanded position.

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.

The present disclosure relates to a power tool (1) driven by an internal combustion engine and comprising a housing (9) and having a service access interface (11) for connecting to an internal control unit of the engine during service. The access interface (11) comprises a connector (21) and an access interface cable, connecting the connector (21) to the control unit. The housing comprises an opening (15), and a grommet (13) is provided configured to clamp the access interface cable or the connector (21). The grommet (13) is configured to be moved between an operating position and a service position. In the operating position, the grommet (13) is located in the opening (15), the access interface cable and connector (21) being fully enclosed in the housing (9), and in the service position, the grommet (13) is located in said notch, the access interface cable or connector (21) extending through the opening inside the grommet (13).

The present invention relates to a portable power tool (1) arranged for driving a rotatable cutting tool (2). The power tool (1) comprises a motor (5) and a transmission part (4) that is arranged to transfer power from the motor (5) to a tool holder (10), and comprises a first arm part (11; 11′) and a second arm part (12; 12′). The first arm part (11; 11′) comprises a first belt pulley (13) and the second arm part comprises a second belt pulley (14), the arm parts (11, 12; 11′, 12′) being slidably connected to each other. The belt pulleys (13, 14) are spaced apart by a certain distance (d-i, d2). The transmission part (4) further comprises a tensioning device (20) with a rod (21), a pre-tensioned resilient device (22), a linkage arrangement (25) and a rotatable part (26). The rotatable part (26) is rotatable between a first, released, state where the belt pulleys (13, 14) are spaced apart by a first distance (d-i), and a second, tightened, state where the belt pulleys (13,14) are spaced apart by a second distance (d2) that exceeds the first distance (d-i), the resilient device (22) being more compressed in the second state than in the first state.

A dust case has improved operability for attachment and detachment. A portable cutting machine includes a cutting machine body to which a blade being circular is attachable, and a dust case detachably attached to the cutting machine body. The dust case includes a detachment operation unit pushable along an imaginary plane parallel to a surface of the blade in detachment from the cutting machine body, and a finger support including a surface frontward from the detachment operation unit in a pushing direction in which the detachment operation unit is pushed. The surface is substantially perpendicular to the pushing direction.

Machines with safety systems are disclosed. The machine may take the form of woodworking machines including table saws, band saws, miter saws, hand-held circular saws, pneumatic chop saws, radial-arm saws, jointers, planars, routers and shapers. The machines may include an operative structure configured to perform a task, where the operative structure includes a cutting tool adapted to move in at least one motion, and a safety system adapted to detect the occurrence of an unsafe condition between a person and the cutting tool and for mitigating the unsafe condition. The safety system may include a detection subsystem and a reaction subsystem. The machine may also include a bypass or override mode where in an injury mitigation system is disabled for certain cuts.

A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.
