Disassembly procedure
◆
◆
◆
◆
1)
Check air pressure is exhausted from the IN and OUT sides.
2) Remove the pressure gauge and the silencer first if they are mounted.
3) Remove the eight hexagon socket head cap screws (8) on the left and the right with a hexagon wrench.
4) Take off the side covers (6) on the right and left.

Maintenance and check
◆
◆
◆
◆
1) Check there is no abrasion, deterioration and deformation of any part. If there is, replace it with new one.
2) If there is any part whose motion is not smooth, wipe off dirt and apply grease.
3) If you move onto maintenance of the body, refer to 2.2 Maintenance of body (P.3).

Reassembly
◆
◆
◆

1) Apply grease to the part marked with in Fig. 1.
2) Pass the piston rod (3) through the body (1) and assemble the piston (4).
3) Apply one drop of Loctite to the thread of the piston nut (7) and tighten it with the socket wrench.
(Torque 5.2Nm)
The piston is not fixed completely (idles) if it is assembled correctly. Do not
tighten it over the necessary torque.
4) Mount the cover (6) to the body (1) after the cover gasket is mounted to the cover (6).
5) Fix the cover (6) by tightening four hexagon head bolts (8) on each side of the cover (eight bolts in
total).
(Torque 3Nm)
