(3) Reassembly of the ball bushing
The Ball Bushing [114] and Holder (A) [124] are
maintained at a smooth fit. When placing the Ball
Bushing [114] into Holder (A) [124], gently hammer it
with a plastic hammer so that the Ball Bushing [114]
is seated into Holder (A) [124] in parallel. After
reassembly, lubricate around the steel balls inside the
Ball Bushing [114] with 2 grams of Nippeco SEP 3A
grease. Apply machine oil to slide pipe (A) and slide
pipe (B) of Hinge (A) Ass’y [87]. When reassembling,
put the Ball Bushing [114] inside Holder (A) [124] as
indicated in (A) of Fig. 55. Visual observation will do
for this insertion. Layout in (A) offers about 30%
higher rated load in (B).
6. Lubrication
Advise the customer to lubricate the machine as indicated below at least once a month. Also, prior to
applying lubricant, any sawdust, dirt or other foreign matter should be thoroughly wiped away with a soft
cloth.
