10. ASSEMBLY
Disassembly should only be carried out by a
qualified technician.
Turn off the power switch before disassembly,
otherwise the machine may operate if the foot switch
is depressed by mistake, which may result in injury.
Be sure to wear protective goggles and gloves when
handling the lubricating oil and grease, so that they
do not get into your eyes or onto your skin,
otherwise inflammation can result.
Furthermore, do not drink the oil or eat the grease
under any circumstances, as they can cause
vomiting and diarrhea.
Keep the oil out of the reach of children.
Assemble each part in order of the numbers.
* (number) indicates part names only. (The numbers do not indicate the order of assembly.)
