A foldable water tray used in a tile cutter includes a water tank having a water chamber, a first tray movable in and out of the water chamber of the water tank between an application position and a storage position, and a second tray pivotally connected to the first tray and biasable relative to the first tray between an extended position where the second tray defines with the first tray a predetermined contained angle and a collapsed position where the second tray covers the first tray and can be moved with the first tray between the application position and the storage position.

A tile saw including a saw unit having a motor and a saw blade, and a base supporting the saw unit above the base, where the base is fixed relative to the saw unit. A carriage is supported by the base. The carriage is translatable relative to the base and the saw unit, where the carriage is translatable along a first plane. The tile saw further includes a table for supporting a work piece to be cut by the saw blade. The table is translatable relative to the base and the saw unit, where the table is translatable along a second plane. The second plane is parallel to the first plane. The table is selectively translatable relative to the carriage.

A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

A mobile earth working machine (10), for example a road milling machine, recycler, or surface miner, includes: a working apparatus (12) for material-removing working of a region of a substrate (U); and an extraction device (40) that is embodied to extract dust-laden air from at least one machine region at at least one extraction location (46), and to exhaust extracted air at a discharge location (50) different from the extraction location (46),
the extraction device (40) comprising a filter apparatus (42) arranged along an operational flow path from the at least one extraction location (46) to the discharge location (50), the filter apparatus (42) encompassing: a filter housing (54); a filter element (52) received in the filter housing (54), the filter element (52) being embodied to remove dust particles from the air flowing through the filter apparatus (42). The filter apparatus (42) comprises a deformation actuator arrangement (44, 76a) that interacts force-transferringly with at least one wall (86) of the filter housing (54) in such a way that by actuation of the deformation actuator arrangement (44, 76a), the at least one wall (86) of the filter housing (54) is deformable orthogonally to its wall surface.

A cutting device including a stand and a saw supported by the stand. The saw includes a motor and a blade rotatably driven by the motor. A pair of rails is supported by the stand. A tray is configured to support an object to be cut on an upper surface and including a roller assembly on a lower surface. The tray is slidable along the pair of rails towards and away from the blade. At least one of the rails is disposed over a basin configured to hold water.
