and Notes on fitting the valve seals The valve seals and must be fitted in the specified directions in accordance with the specified procedures. If any of these seals is fitted in an improper direction or in improper procedures, the seal will be damaged, thereby causing fluid leak. Fitting procedures ①Check the direction of the valve seal. Set the marked side of the seal inside. (See Fig. 1.) ②Fit the valve seal to the cushion valve shaft or check plug shaft in the correct direction. (See Fig. 2.) ③Screw in the valve seal taking care not to drop it. (See Fig. 3.) CAUTION If the seal is screwed in after it is inserted to the hole in the cover, the seal may be damaged.

(Identification mark) HNBR: orange Fluorocarbon: white Fit the seal with the marked side on the inside of the cylinder.

CAUTION Notes on fitting the valve seals and The valve seals and must be fitted in the specified directions in accordance with the specified procedures. If any of these seals is fitted in an improper direction or in improper procedures, the seal will be damaged, thereby causing fluid leak. Fitting procedures  ①Check the direction of the valve seal.   Set the marked side of the seal inside. (See Fig. 1.)  ②Fit the valve seal to the cushion valve shaft or check   plug shaft in the correct direction. (See Fig. 2.)  ③Screw in the valve seal taking care not to drop it.   (See Fig. 3.)

Notes on fitting the valve seals and  The valve seals and must be fitted in the specified directions in accordance with the specified procedures.  If any of these seals is fitted in an improper direction or in improper procedures, the seal will be damaged, thereby causing fluid leak.  Fitting procedures  ①Check the direction of the valve seal.   Set the marked side of the seal inside. (See Fig. 1.)  ②Fit the valve seal to the cushion valve shaft or check plug shaft in the correct direction. (See Fig. 2.)  ③Screw in the valve seal taking care not to drop it. (See Fig. 3.) CAUTION If the seal is screwed in after it is inserted to the hole in the cover, the seal may be damaged.

Notes on fitting the valve seals and The valve seals and must be fitted in the specified directions in accordance with the specified procedures. If any of these seals is fitted in an improper direction or in improper procedures, the seal will be damaged, thereby causing fluid leak. Fitting procedures ①Check the direction of the valve seal. Set the marked side of the seal inside. (See Fig. 1.) ②Fit the valve seal to the cushion valve shaft or check plug shaft in the correct direction. (See Fig. 2.) ③Screw in the valve seal taking care not to drop it. (See Fig. 3.)

CAUTION If the seal is screwed in after it is inserted to the hole in the cover, the seal may be damaged.

(Identification mark)     HNBR : orange Fluorocarbon : white Fit the seal with the marked side on the inside of the cylinder.

Notes on fitting the valve seals and The valve seals and must be fitted in the specified directions in accordance with the specified procedures. If any of these seals is fitted in an improper direction or in improper procedures, the seal will be damaged, thereby causing fluid leak. Fitting procedures ①Check the direction of the valve seal. Set the marked side of the seal inside. (See Fig. 1.) ②Fit the valve seal to the cushion valve shaft or check plug shaft in the correct direction. (See Fig. 2.) ③Screw in the valve seal taking care not to drop it. (See Fig. 3.)
