To drain, remove drain plugs (D in FIGURE 5, page 6)
at the bottom. AEON PD Synthetic Lubricant should be
drained after 6000 hours of operation. Re--fill with fresh
AEON PD oil. If mineral oil is used, perform the above
oil--change maintenance every 1500 hours. Rec-
ommended service intervals are for normal blower
operating conditions. Severe operating conditions may
warrant more frequent oil changes.
Laboratory
analysis of lubricant should be used to help determine
the optimum oil change interval.
For best performance and equipment protection, use
AEON PD Synthetic Lubricant, which has been specifi-
cally formulated for positive displacement blowers.
If you choose not to use AEON PD Synthetic Blower
Lubricant, select an oil with rust and oxidation
inhibitors, anti--foam additives, and the viscosities
listed in FIGURE 7. Do not use an oil that contains EP
additives.
Flush the oil whenever a change is
made from one type of oil to another.
You will need to flush the oil whenever a change is
made from one type of oil to another. Drain the current
lubricant as thoroughly as possible. Refill with the new
lubricant. Fill to the normal level of the blower, which
is at the middle of the sight glass when the machine is
not operating. Run the blower for one hour. Shut off
the blower and drain the lubricant completely. Refill the
blower again with the new lubricant.
