abnormal wear or scratches. If necessary, replace belt ten-
sion 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 projec-
tionally acting force and should not sink within 8.5 sec-
onds.
