Assembly must be done carefully and accurately, for the safety of the person(s) doing the as-
sembling and to ensure proper machine operation.
Assembly should be done on a flat, solid surface, using the proper tools and wearing suitable
clothing, making sure that all people not involved in the assembly are kept at a safe distance.
Assemblers must provide suitable lifting mechanisms and supports for stabilizing the partially
assembled units, so as to prevent them from falling and causing damage or injury. The steps for
assembly are illustrated in following. Depending on the experience of the assemblers and the
tools available, it is not necessary that the instructions be followed in the exact order shown
here, but the safety precautions described above must always be strictly and carefully followed.
