Note)
・
Although the rotating angle of external absorber type can be made smaller by screwing in a
shock absorber, do not make it smaller than the minimum rotating angle of 84° (90° specification)
and 174° (180° specification). This will increase the deflection angle on the working face of the
shock absorber’s piston rod and arm, causing damage to the shock absorber.
・
Pay attention that the hexagon nuts of the shock absorbers for size 10 external absorbers are
directional. Mount it so that the surface without chamfers is the seating surface.
Piping
Figure 8 and Table 9 show locations and sizes of piping ports.
Ports can be selected from two sides. Plug the ports that are not used.

・
Rotary table ports and plate have a fixed orifice. Do not make the diameter of this hole larger by additional
processing.
If the hole diameter is made larger, rotation speed and impact will increase, which may cause breakage of
the product.
Preparation before piping.
a) Before piping is connected, it should be thoroughly blown out with air to remove dust and scale from
inside the pipe. Dust and scale on the inlet side of the filter can be removed, but those on the outlet side
cannot be removed, so they can enter the solenoid valve or rotary table, which causes malfunction or
shortens product life.
b) When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material
do not enter the piping. Also, if pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the
threads.
Air supply
Air should be filtered with an air filter before it is supplied to the rotary table.
Since Series MSQ requires no lubrication, it is not necessary to lubricate using a lubricator.
