The first radio unit is (38) is arranged on a front side (57) of the device housing (31), wherein the front side (57) is lying opposite a rear side (56) of the device housing (31) facing the operator in a working position of the remote control (13).

A tile saw with retractable water tank suitable for being detachably installed in a supporting unit is disclosed to include a base unit including a seat body and a water tank, a connecting unit, and a saw unit. The water tank has a tank bottom, a surrounding portion made of a soft material and a hard portion, and is operable to move relative to the seat body between an enlarged state and a reduced state. When the tile saw with retractable water tank is not in use, the base unit can be unloaded from the supporting unit to shorten the storage height to facilitate handling, and the water tank can be operated into the reduced state to reduce the height of the base unit. And reduce the storage volume.

A wet cutting saw for cutting a ground portion, the wet cutting saw including a blade rotatable about an axis, a liquid feed conduit for feeding liquid onto a surface of the blade as it rotates, a frame for carrying the blade and configured to travel over a surface of the ground portion, and a mounting assembly that mounts the blade to the frame, at least part of the mounting assembly pivotable relative to the frame to raise and lower the blade relative to the frame.

A method for controlling a wall saw system during creation of a separating cut in a workpiece. The wall saw system includes a saw head, a pivotable saw arm, a first saw blade, and a larger second saw blade. The separating cut is performed in a plurality of main cuts, where the parameters of the main cuts (saw blade diameter of the saw blade used, main-cut angle) are defined before the start in a main-cut sequence. After the processing of the separating cut by the first saw blade is concluded, the controlled processing of the separating cut is interrupted by a control unit and the wall saw is moved into a parking position such that all actions of the saw-blade change (swinging out the saw arm, removing the first saw blade, installing the second saw blade, and swinging in the saw arm) can be performed.

A method for controlling a wall saw system during creation of a separation cut in a workpiece between a first and second end point, is disclosed. The separation cut is carried out in a plurality of main cuts. In addition to the main-cut sequence, an overcut sequence having at least two overcuts is defined for each end point defined as a free end point. For each overcut sequence, a starting position and an end position are defined, the overcuts being carried out therebetween. The wall saw is positioned in the starting position and is pivoted into a first overcut angle; subsequently, the saw head is moved by way of the inclined saw arm until the end position has been reached. The wall saw is displaced back into the starting position and pivoted into a second overcut angle. This sequence is repeated until all of the overcuts have been carried out.

A method for controlling a wall saw system during the creation of a separating cut in a workpiece. The movement of the saw head is controlled at the end points such that a boundary of the wall saw facing the end point coincides with the end point after the pivoting movement of the saw arm. In the case of a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade. In the case of an obstacle, the boundary of the wall saw is formed by the saw blade edge of the saw blade if the processing occurs without the blade guard or by the blade guard edge of the blade guard if the processing occurs with the blade guard.

A system and a method for sawing control joints in concrete barriers is provided. The system includes a barrier mounting frame slidably mountable about the barrier, on the top, first and second lateral faces of the barrier. The system also includes a saw attachment having a circular saw attached thereto, the circular saw being manually operable. A linkage assembly connects the frame mounting barrier to the saw attachment, and allows to manually move the circular saw up or down, and towards or away from the barrier, when in use, to create the control joint transversally along the top, first and second lateral faces of the barrier.

Cutting apparatus attachable to a skid steer. The apparatus includes a house attached to a skid steer. The house is attached to an arm, which is attached to a motor that drives a blade. A single hydraulic circuit originating from the skid steer powers both the motor and a cylinder that is capable of pivoting the arm or rotating a guard that partially surrounds the blade. The user is able to operate the motor and cylinder independently of one another. The cutting apparatus is capable of cutting a straight line on horizontal, raised, and vertical surfaces.

Various dust collection apparatuses are disclosed. In a first example, a dust collection apparatus includes a vacuum source configured to provide a negative pressure, and a multistage filter configured to collect airborne dust drawn by the negative pressure. For this example, the dust collection apparatus includes a dust tray having a shared dust containment area in which the shared dust containment area is a single compartment configured to receive the airborne dust collected by the multistage filter directly from each of a plurality of stages of the multistage filter. In another example, a dust collection apparatus includes a filter, a filter housing configured to house the filter, and an inlet coupled to the filter housing. For this example, the inlet is configured to receive a flow of airborne dust drawn by a negative pressure, and is further configured to mitigate an impact of the airborne dust on the filter.

Various dust collection apparatuses are disclosed, which include a vacuum source, a circular saw blade, and a worktable comprising a center slot axially aligned to the circular saw blade. In a first aspect, the center slot includes an air flow channel proximate to an anticipated point of contact between the circular saw blade and a workpiece, and the vacuum source is configured to provide a focused negative pressure beneath the worktable via the air flow channel. In another aspect, the vacuum source provides a negative pressure beneath the worktable at the center slot, and a multistage filter is included to collect airborne dust drawn by the negative pressure from an area proximate to the center slot. In yet another aspect, the vacuum source is configured to provide a first negative pressure beneath the worktable at the center slot, and a second negative pressure via an auxiliary port.
