) [480g (1.06lb)]. Insert the entire bag of
desiccant that was purchased for use with the

surface on the bottom. Then place filter plate B in
position and perform tapping.
Be certain to use the specified NABCO
desiccant (41213640010).
Use of a desiccant other than that specified is
extremely dangerous. It can result in the
desiccant deteriorating and being lost, with
pieces blocking the brake piping and preventing
normal brake operation.
The desiccant used is different than that used
for NABCO DR-41, DR-42, and DU-4. Be careful
not to use the wrong type.
WARNING
If less than the specified amount of desiccant
is used, the desiccant may deteriorate and be
lost, with pieces blocking the brake piping and
preventing normal brake operation. Be sure to
insert the specified amount.
