[Caution]
- When removing the trimming assembly, make sure that 2 people hold the circled sections indicated below.
- If the removed trimming assembly is placed on the floor, do not place it directly on the floor. Due to the protrusion part on the
lower side of the trimming assembly, placing it directly on the floor may result in breakage. Be sure to place the trimming assembly
by using the bundles of paper etc. as shown below.
