Separator/Lubricator Maintenance (If
equipped)
Check oil and water levels regularly, and perform
these maintenance items weekly:
A. Disconnect air supply to machine.
B. The Separator (Filter) unit is equipped with an auto-
matic drain and should not normally need draining.
C. If the fluid level is greater than 1/4" from the top of
the gauge, add oil. Remove the filler plug on top of the
lubricator and add SAE 10W non-detergent oil or an air
tool oil to bring the level up to 1/4" from the top of the
gauge. Replace filler plug and clean up any spilled oil.
D. Adjust the oil flow by turning the black flow adjust-
ment knob and turning it to increase or decrease the
flow. Watch the formation of oil drops in the see-
through oil chamber. Reconnect the air supply and
continually cycle the bead loosener through full strokes
and count the drips during the cycles. The delivery of
oil to the airline should be about 1 drop per 10 cylinder
cycles. Adjust flow as required.
Oil Injector Maintenance (If equipped)
The oil injector requires servicing as least annually.
The oil level in the oil reservoir tank should be checked
regularly.
Add oil to oil reservoir tank when fluid level is a quar-
ter full or below. Remove cap from the oil reservoir
tank and add Chevron Regal®
R & O 32 oil to full line
(air tool oil is an acceptable substitute). Replace cap
and clean up any spilled oil.
Important: An air lock will form if the hose between
the reservoir and injector is ever empty of oil. In this
case, after filling the reservoir tank, the line must be
bled of air at the injector connection as follows:
1. Disconnect all power sources, both air and elec-
tricity inputs. Allow any stored air in the reservoir to
escape by depressing the inflate pedal.
2. Remove the side panel and locate the oil injector.
3. Prime the oil injector.
a. Oil Injector With Bleeder Screw
Loosen bleeder screw until oil drips from screw and
all air is relieved from the oil line hose. Retighten the
bleeder screw.
b. Oil Injector Without Bleeder Screw
Remove the oil line hose from the injector barb fit-
ting. Allow air to escape from the hose by lowering the
hose end below level of reservoir until oil is present.
Drip oil into hose barb fitting on injector until barb fit-
ting is full. Reinstall oil line hose onto oil injector barb
fitting.
4. Reconnect air/electric sources and cycle the clamp
control pedal a few times checking for oil and air leaks.
5. Test the machine for full function before returning
the machine to operation.
6. Monitor oil consumption to ensure oil is being
used in system.
