sha.
3) Excessive force on the outer casing or on the
inner sha while disconnecting from Motor or

sha and lubricate with graphite grease or
multipurpose 3 grease to get the better life of
the sha.
5) Do not weld or braze the inner end ttings.
6) e stieners are provided at either ends of
both outer casings to prevent excessive bending
of the sha at the ends. Do not apply excessive
load on the stieners while Working.

tment of new inner sha. e inner sha Will
beat up heavily for few minutes before setting

vibration settles down And then screw on any
selected assembly on the tool end.

for the sha is 500mm.
