AAF International AAF-CY44-50 - Manual (Page 12)

Shaft Bearings- Belt drive models (20HP and larger) have shaft bearings.
Lubricate every 6 months or 1,500 hours, whichever comes first with .25-
.50 oz of grease.
If motor will operate 24 hours per day or in a dirty, dusty, high humidity or
extreme weather or temperature environment, consult motor manufacturer
for lubrication recommendations.
When adding a lubricant, keep all dirt out of the area. Wipe the fitting
completely clean and use clean grease dispensing equipment. More
bearing failures are caused by dirt introduced during greasing than from
insufficient grease.
Explosion door-optional. Open the door and inspect the hinges and
Brixon latches every six months or more frequently if cold and/or dusty
environmental. Make sure all parts move freely. Typically the hinge and
Brixon latch pivot point, which is the bearing pin about which the laminated
cam pivots, should be oiled every six months with SAE 10-20 oil. For
additional information contact Brixon Manufacturing Co. at 1-800-
LATCHES.
5.4 AFTER FILTERS – MAINTENANCE
Zipper bottom style. Shut off blower, unzip and shake out collected dust
into suitable container. Do not allow more than one foot of dust to
accumulate in each bag.
Tubular style. Shut off blower, shake filters with either hand shaker or
optional motorized shaker for 15-30 seconds every 3-4 hours. Remove
dust from dust chamber or optional hopper/drum. Do not allow to overfill.
5.5 AFTER FILTERS – REPLACEMENT
If system begins to loose suction and shaking of filters does not improve
suction, then filter bags should be replaced. Typical filter life is 2-5 years.
Filter removal and washing is not recommended, since the filters may
shrink and not be able to be re-installed.
Zipper bottom style. Unscrew clamp while holding onto bag. Slip off of
collar. Slide new bag onto collar. Rotate until zipper is in desired location.
Position clamp above lip on collar and tighten.
Tubular style. Filters have a grooved spring sewn in both ends, which
permit the filter to snap into plenum and dust chamber cell plates and form
an air tight seal. (If after filter is enclosed, remove both access panels
with care. Two people are required, due to the weight of panels).
Remove cap end and shaft collar from one side of each shaker bar. Pull
