When stacking up the machines for storage, only two
units stacking is acceptable.The mass of the lower
machine should be larger than that of the upper one.
Select a leveled floor with sufficient strength for stacking
up the units.
Before stacking the machines up, check the machine for
any deformation of bonnet, looseness or missing of bolts,
and other parts.
When stacking the units up, be sure to fix them as shown
in the figure so that the balanced weight is applied to
each squared lumber (1) for preventing a sideslip or a
collapse.
Never operate the machines with stacking conditions. It
is very dangerous.
It is dangerous to stack the machines, because they
could fall down due to sideslip or collapse when an
earthquake happens. Pay careful attention to the storage floor for safety.
