All moving parts of 'FRIENDS' Machines are protected by internationally desirable and approved Safety Guards. In addition, a specially designed Guard protects the Operator from the Moving Block. Should any object comes between the Moving Block and the Guard, a slight backward movement of the Guard will occur stopping Moving Block immediately, switching-off the starting mechanism. until and unless the Guard is relocated, the Machine remains at a standstill and unaffected by any attempt to actuate it through the starting mechanism. The sensitive 'Trip Bar' and 'Knee guard' come standard in FRIENDS. These Safety Devices assure that users are kept out of harms' way.
