5.6 LUBRICATION FOR MODEL DL12670
Do not over grease bearings. Overfilling can lead to
excessive heat and/or unseating of the seals. Add
grease slowly and under light pressure. Whenever
possible, rotate bearing slowly while lubricating.
NOTE
Polyurea and lithium-based greases are not
compatible. Mixing the two grease types may lead to
premature failure.
IMPORTANT
The DL12670 has one greaseable bearing located near
the engagement handle and another located at the base
of the discharge tube. Lubricate the machine periodically
with a lithium-based grease. Extreme working conditions
will require more frequent greasing.
