Force Feed Lubrication: After one minute of operation,
there should be a register of pressure in the gauge (D)
FIGURE 5, page 6. IF there is none, prime the oil
pump (E) FIGURE 5, page 6.
Do not overfill as this will tend to
cause excessive heating of the gears
and may damage the unit.
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.
Recommended
service intervals are for normal blower operating condi-
tions. Severe operating conditions may warrant more
frequent oil changes. Laboratory analysis of lubricant
should be used to help determine the optimum oil
change interval.
Force Feed Lubrication: Oil should be drained at the
drive headplate (K) and gear sump (C) in FIGURE 5,
page 6. The mesh--type strainer (G) FIGURE 5,
located in the sump, should be cleaned each time the
oil is changed. There are two perforated brass screens
located at the oil line connection to the headplates (F)
FIGURE 5. These should be removed and cleaned or
replaced as necessary. Oil pressure should be in the
range of 10 to 15 psi.
Oil pressure is controlled by the relief valve (J),
FIGURE 5, page 6, in the bypass line from the pump
to the oil sump. If it is necessary to change the pressure
adjustment, remove lower cap and gasket from the
relief valve. Loosen the locking nut and turn the
adjusting screw clockwise to increase, and counter--
clockwise to decrease the oil pressure. Tighten locknut
and replace gasket and cap. Mount the oil pressure
gauge (D), FIGURE 5, on a vibration free panel to
prevent gauge damage and inaccurate reading.
Splash lubrication: OIl should be drained at the Drive
Headplate (L) and Gear Sump (C) in FIGURE 5, page
6.
For the best performance and equipment protection,
use AEON PD Synthetic Lubricant, which has been
specifically formulated for positive displacement
blowers.
If you choose not to use AEON PD Synthetic Blower
Lubricant, select an oil with rust and oxidation inhibi-
tors, anti--foam additives, and the viscosity listed in
FIGURE 7, page 8. Do not use an oil that contains EP
additives.
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 new
lubricant. Fill to the normal level of the blower, which
is 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.
