Bending radius: h
60 mm (2.36 in) or more
2. BELT TENSION ADJUSTER
1) Visually check oil seals for leaks, and rod ends for abnormal wear or scratches. If necessary, replace belt tension adjuster.
CAUTION: Slight traces of oil at rod's oil seal does not indicate a problem.
2) While holding tensioner with both hands, push the rod section against floor or wall ensuring the rod section will react as follows:
(1) When applying a force of 147 N (15 kg, 33 lb), the rod section should not sink.
(2) When applying a force of 147 to 490 N (15 to 50 kg, 33 to 110 lb), the rod section should maintain a projectionally acting force and should
not sink within 8.5 seconds.
3) Measure the extension of rod beyond the body. If it is not within specifications, replace with a new one.
