5. Changing Oil:
a. Place a collection pan or pail under each
drain plug.
b. Remove each drain plug.

utes to drain.

equivalent to each reservoir

inside the reservoirs during
machine operation. Changing oil
removes this water and prevents
it from damaging the gears and
bearings.

and fill plugs.

drive covers.
6. Cleaning Breathers:
a. Remove breathers and blow
out with an air hose.

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.
