5. Changing Oil:
a. Place a collection pan or pail under each
drain plug.
b. Remove each drain plug.
c. Flush each case and allow several min-
utes to drain.
d. Dispose of the oil in an approved manner.
Do not contaminate the worksite with used
oil.
e. Install and tighten the drain plugs.
f. Remove fill and level plugs.
g. Add Walinga Blower oil or
equivalent to each reservoir
until the oil is just starting to
come out of the level plug
hole.
IMPORTANT
Condensation forms and collects
inside the reservoirs during
machine operation. Changing oil
removes this water and prevents
it from damaging the gears and
bearings.
h. Install and tighten the level
and fill plugs.
i. Install and secure the belt
drive covers.
6. Cleaning Breathers:
a. Remove breathers and blow
out with an air hose.
b. If dirt has caked up in the
breather, soak in good
solvent and then blow out. It
may be necessary to use a
probe to loosen the dirt.
c. Install and tighten the
breather.
d. Install and secure the belt
drive covers.
e. Clean vents in end plates
located under the blower on
either side of the drain plug.
