• Do not loosen the adjusting kit located
to the cover. Because the adjusting kit
has set the relief pressure, the lock nut
shall not be removed if not required
for adjustment of the pressure. If the
adjusted value is changed, the modu-
lating time may be shorter (PTO clutch
gets connected in haste) or the PTO
clutch may be hardly connected. In
case the adjusting kit is removed by
mistake, perform adjustment as speci-
fied with a pressure gauge.
b. Caution for Assembly
Apply oil sufficiently to all the parts after washed, not to
cause damage thereon when assembling.
