Maintenance and check

1) Check there is no abrasion, deterioration and deformation of any part. If there is, replace it with new one.
2) The end of IN port has a mesh filter built in. Remove dust from the filter by air blowing.
3) If there is any part whose motion is not smooth, wipe off dirt and apply grease. Apply one drop of
Turbine oil to the switch valve.

Reassembly

◆
◆
1) Mount the switch valves (9) through (13). (These are precision parts and should be handled with care.)
2) Mount the check valves (5), and (7) on one side, and mount the side plate insert A (3) which is
mounted with the side plate insert gasket A (15) and the side plate insert B (4) which is mounted with
the side plate insert gasket B (16), then mount the side plate (2) on them.
It should be noted the
check valves (5) have different mounting directions.
3) Assemble the check valves on the other side. At this time, hold down the spring to overcome its
reaction force.
Side plate insert A (3) and side plate insert B (4) are different between the parts for the left and the right.
