THE BOTTOM DRUM
1. Slide the bearing block on the shaft.
Hold it in place with Ø 42 spiral ring.
2. Carefully, and with two people, set the
bottom drum with support arm onto the
side supports of the stand as shown,
so that the bearing blocks slot into the
channels provided by the side supports.
The larger diameter shaft should be at
the leg end of the stand.
3. At each side, line up the holes in the
side support with those in the bearing
block and insert a M8X65 hex bolt from
one side, then a flat washer, lock washer
and nut from the other side. Tighten
with a wrench.
THE MIXING BLADES
Mount the mixing blades inside the bottom
drum loosely as shown - Two holes are
provided at the base of the drum into
which a M8X20 bolt may be inserted from
the outside. A leather washer, flat washer,
lock washer and a nut should be threaded
on loosely on the inside. The leather
washer should be placed under the blade
down against the drum.
NOTE: Two arrows are labeled on upper
drum and bottom drum to make their
position relative. If you have any diculty
in correctly positioning the mixing blades,
it is helpful if you temporarily mount the
upper drum on the top of the bottom drum,
rotating it so that the two arrows line up.
