IMPORTANT — DRUM HEAD SEAL CARE
On each end of the mixing drum is a drum head containing self
adjusting paddle shaft seals. These seals consist of packing
rings, split glands and spring actuated adjusters. A properly
maintained seal prevents material from working around the
paddle shaft, causing excessive wear. The following is a
suggested procedure of maintenance for protection of the
paddle shaft and bearings:
A. Keep the drum head clean of plaster built up, so the spring
adjusters will be free to work.
B. Replace with one new ring of packing and waterproof grease
when split gland or pressure plate is about to bottom out against
the end of the drum.
New Packing
When the old packing is to be completely replaced, coat shaft
and packing generously with a good grade of waterproof grease
and insert packing rings. Tighten the two spring adjuster nuts
on each end until the spring is compressed to 1¾ inches or the
top of the adjusting nut is even with the top of the drum head.
Also, whenever the paddle shaft is removed, new waterproof
grease should be packed around the ball bearings in the drum
heads before reinstalling the shaft. Fill the cavity completely.
DRUM GRILL
AND CAUSE
The drum opening is covered by a steel grill that is hinged for
easy cleaning. This grill should be closed at all times when
mixer is in use. Do not remove the grill or grill opening bar.
Keep the grill clean by washing it down daily.
CAUTION: Stop the engine before allowing anybody to put
their hands in the mixing drum.
