It is important that the moisture in the air is kept controlled and maintenance of the pneumatic motor is undertaken periodically as per the instruction manual provided by the manufacturer. The storage and the transportation of the machine to the site are generally done in the large toolboxes made out of aluminum and powder coated. In certain cases due to the weight restriction, the machine is also carried in large suitcases. In that case, the machine is properly packed in order to avoid any damage during the movement of the machine from one site to another.
