5.1 Changing the bur
FIG. 3
Push-button bur locking.
1. Press the push-button and sim-
ultaneously pull out the bur.
2. Press the push-button, insert the new
bur all the way to the stop and re-
lease the push-button.
3. Check that the bur rotates freely and
that it is locked by gently pushing and
pulling the bur.
WARNING
The use of a coolant while the in-
strument is in operation is mandatory,
failure
to comply with this re-
commendation may result in
overheating and burns or product fail-
ure. Set the water quantity for the
cooling spray to at least 60 ml / min.
CAUTION
The device must not be started without
a bur inserted. Comply with maximum
lengths by always inserting the bur as
far as possible into the locking mech-
anism. If a bur is operated at high
speeds when incorrectly mounted (i.e.
not fully inserted into the locking mech-
anism, or being longer than the values
specified above) this can cause a cent-
rifugal force which may bend or break
the bur.
CAUTION
Never insert or remove a device while
the micromotor is rotating.
WARNING
Do not touch the dental bur while it is ro-
tating.
CAUTION
Never press the push-button while the
instrument is in operation.
CAUTION
Always check that the bur is in place
and rotates freely. If it is blocked, con-
tact your usual supplier or Bien- Air
Dental SA for repair.
CAUTION
Always ensure that the spray outlets
are not obstructed.
