Replacement of rotatable cutting discs of a power tool

A power tool comprising:

• a rotatable support arrangement for supporting at least one cutting disc and being configured to be rotatably driven by an electric motor;
• an upper shroud member and a lower shroud member which cooperate to define a volume in which the at least one cutting disc can be supported, the rotatable support arrangement coupled to the upper shroud member such that movement of the upper shroud member towards the lower shroud member causes the at least one cutting disc to protrude through an opening in the lower shroud member;
• a biasing member for urging the upper shroud member and the lower shroud member away from each other;
• and
• a limiting mechanism for limiting a range of movement of the upper shroud member relative to the lower shroud member under action of the biasing member, a first part of the limiting mechanism being carried by the upper shroud member and a second part of the limiting mechanism being carried by the lower shroud member,
• wherein the limiting mechanism can be disengaged by opening the upper shroud member via at least one hinge coupling, thereby increasing the range of relative movement of the upper and lower shroud members,
• wherein the limiting mechanism is configured such that when the first and second parts of the limiting mechanism are urged against each other upon a user moving the upper and lower shroud members towards each other,
• wherein one of the first and second parts of the limiting mechanism causes the other to recoverably flex so that they can move past each other,
• wherein upon the first and second parts of the limiting mechanism being subsequently brought back into contact with each other under action of the biasing member urging the upper and lower shroud members away from each other, the first and second parts of the limiting mechanism restrict an extent to which the upper and lower shroud members can be moved away from each other under action of the biasing member,
• wherein one of the first and second parts of the limiting mechanism comprises a spring that defines a first surface along which the other of the first and second parts of the limiting mechanism can ride for facilitating such the first and second parts to move past each other when urged against each other upon a user moving the upper and lower shroud members towards each other, and
• wherein the spring also defines a second surface against which the other of the first and second parts of the limiting mechanism rest when the first and second parts are subsequently brought back into contact with each other under action of the biasing member urging the upper and lower shroud members away from each other.
