5.0 MAINTENANCE
5.1 MAINTENANCE SCHEDULE
Daily or Weekly- Inspect the dust level in the 55 gallon drum(s) or other
dust storage container. Do not over fill. Empty as necessary.
Monthly- Inspect the fan exhaust for excessive emissions. Inspect the
flexible hose and drum cover, etc, to make sure they are airtight.
Every 6 Months- Lubricate shaft bearings, if a belt drive unit.
Every 12 Months- Lubricate motor.
5.2 UNIT SPECIFIC
CYD & CYA series. Do not allow dust drum(s) to overfill otherwise the
collected dust will come out of the exhaust. Shut off fan before inspecting.
Drum cover and hose must be air tight. Check cover gasket frequently.
Any slight leak will cause dust to be discharged from fan.
CYB series. Do not allow dust drawer to overfill, otherwise collected dust
will come out of the exhaust. Shut off fan before inspecting. Check door
gasket frequently for positive seal. Any slight leak will cause dust to be
discharged from fan.
CYH series. Do not let dust in the hopper get closer than 10” to the cone
end of the cyclone, otherwise the collected dust will come out of the
exhaust. Check dust level through sight glass on the front of the hopper.
5.3 LUBRICATION
Grease- Bearing grease will lose its lubricating ability over time, not
suddenly. The lubricating ability of a grease, over time, depends primarily
on the type of grease, the size of the bearing, the speed at which the
bearing operates and the severity of the operating conditions.
A high grade poly urea-based ball or roller bearing grease should be used.
Recommended greases for standard service conditions are Exxon Mobil
Polyrex EM, Texaco Polystar, Rykon Premium #2, Pennzoil Pen 2 Lube
and Chevron SRI. Lithium based greases are not compatible with poly
urea-based greases.
Motors- Motors that are 3HP and larger typically have two grease fittings.
Lubricate motor bearings every 12 months or 3,000 hours of use,
whichever comes first, with .25-.50 oz of grease.
