When you wish to change a position of the side handle, turn grip of the side
handle counterclockwise to loosen it, and then fasten it firmly.

When boring a hole, there can be a case where the machine attempts to rotate
by the reaction at the time of penetrating a concrete wall and/or when a tip of
the blade comes in contact with the rebar.
Firmly fasten the side handle and hold the machine with both of your hands.
Unless you hold it securely, an accident can occur.
