PRODUCT SPECIFICATIONS
CHARGING THE BATTERY
Use only the charger that came with your BFC
3
. Use of
another charger could damage the unit and will void
the warranty.
With a fully charged battery, the BFC
3
can dispense
about 60 full 50ml heavy-body VPS cartridges. When
battery output is reduced, the low battery LED
K
will illuminate, indicating that the BFC
3
battery should
be charged soon. The BFC
3
will dispense up to 10 full
cartridges after the low battery LED illuminates.
The BFC
3
battery is rated for 500 recharges (about
30,000 cartridges) before replacement will be required.
Contact Practicon for battery replacement service. Do
not attempt to open the unit or service the battery.
CLEANING AND DISINFECTION
This product must be disinfected for each patient.
Failure to follow these guidelines could damage the
device and void the warranty.
Clean the body of the device and plungers with disin-
fectant wipes. Follow all disinfectant manufacturer’s
guidelines for use.
• Do not use any cleaner containing bleach.
• Do not immerse in liquid.
• Do not place in autoclave.
PREPARING THE BFC
3
FOR USE
Select the 50ml plunger
C
or 75ml plunger
D
as
appropriate for your material cartridge. Open the
cartridge clamp
G
. Hold the BFC
3
in one hand and
press upward on the plunger release lever
M
with your
thumb. With the other hand, insert the plunger
teeth
side down
into the plunger slot
L
in the front of the
unit and slide it back as far as it will go. Release the
plunger release lever. The BFC
3
is now ready to use.
OPERATION
Using the BFC
3
is very much like using a manual
impression gun, only easier. Instead of having to
repeatedly squeeze a large spring-loaded trigger with
your hand, BFC
3
dispenses automix material with the
press of a button.
LOADING A CARTRIDGE
Press the plunger release lever
M
upward with your
thumb, pull the plunger back until it stops, and then
release the lever. Open the cartridge clamp
G
and
insert an automix cartridge. Close the cartridge clamp.
Press the plunger release lever again and slide the
plunger forward until it contacts the cartridge.
Release the lever.
ADJUSTING THE FLOW RATE
The BFC
3
can dispense material at a rate that ranges
from 0.6 to 1.7ml/sec. Adjust the flow rate by rotating the
dispensing speed control
J
between the MIN and MAX
settings. Experiment with different flow rates to find the
setting that works best for your practice and procedures.
DISPENSING MATERIAL
As with all impression guns, express the first drops of
material onto a paper towel or tray liner.
Press the dispensing activation trigger
H
with your
index finger to start the flow of material. Release the
trigger when enough material has been dispensed.
The BFC
3
includes an anti-drip feature that momentarily
reverses the plunger when the dispensing trigger
is released, and an auto-stop feature with overload
protection when a cartridge has been emptied.
Problem
Resolution
Cannot insert plunger
Insert the plunger into the slot on the front of the unit
teeth side down
.
The slot is keyed so that the plunger can only go in one way.
Dispensing is too slow/fast
Adjust the dispensing speed control to increase/decrease the flow.
Unit will not dispense material
Cartridge is empty and auto-stop engaged; replace cartridge.
Battery charger is still connected to unit (by design, unit will not oper-
ate with charger connected); disconnect battery charger from BFC
3
.
Battery will not charge
Contact Practicon for battery service. Do not attempt to open the unit
or service the battery.
