WARNING
- This procedure requires you to put your hand into the drive section,
where your hand or fingers could be caught or cut off.
During this operation, allow no one else to touch the machine.
- If you keep the splash cover closed after moving the axes, you have
to perform the adjustment operation with the interlock system
released. Since there is a driving section near your working section,
if the interlock system is canceled, your hands or arms may be
caught or amputated due to unexpected machine operation.
After you move the axes, be sure to open the splash cover in order
to activate the interlock of the cover.
CAUTION
When you perform maintenance with the partition removed, observe
the following precaution. If you stand the removed partition against
the machine, you may receive injury by the partition if it is toppled by
the earthquake or like that.
After taking off the partition for maintenance purposes, store it
sufficiently away from the working area.
CAUTION
If you don't use the amplifier adjustment driver designed specifically
for this use when you turn the sensitivity regulation dial, the dial may
be damaged or broken.
Ensure to use the amplifier adjustment driver (black resin).
