Meter Body Disassembly and Inspection

〉

（1）流量計の六角ボルト 4 本を外し、計数部と本体部

を分離します。

Take  off  four  hex  bolts  of  the  meter  and  separate 

the register from the meter body.

（2）計数部と前蓋部を持って水平に取り外してくださ

い。計量室を点検し、各部のスケールを洗浄してく
ださい。回転子を落下させますと破損しますので、
取り扱いには充分注意してください。

Holding  the  register  and  front  cover,  separate 

horizontally.  Inspect  the  measuring  chamber  and 

remove  scales  on  individual  parts.  Exercise  extra 

care not to drop the rotors or they will be damaged.
