Operation
On the Ultima 250 units only one hand piece can be run at a time. They are activated by an
automatic holder when removed from its place. The hand piece must be placed in the same holder
to de-activate the hand piece in order to allow another hand piece to function. The holders and
hand piece tubing has been color coded for your convenience. Red is the low speed hand piece
(Polisher), White is the accessories line or Piezo line if the unit is equipped with one, and Blue is
for the high speed drill. The hand piece pressures have been preset at the factory. To run the
hand piece simply step on the foot control pedal. Hand piece Pressures: HP 1. Red line (Polisher)
should be set to 40 – 50 Psi, HP 2. White line is an accessories line and is not set, HP 3. Blue
line (High speed drill) should be set to 32 Psi. To change individual hand piece pressures look on
the back of the unit under the captions HP 1, HP 2, HP 3, inside the holes are small adjustment
screws. To decrease individual air line pressure turn adjustment screw clockwise. To increase
individual air line pressure turn counter clockwise.
To install hand pieces simply mate the rear end of the hand piece with the hand piece tubing
connector.
1. The UDS low speed hand piece (Polisher) is a 4:1 E-style hand piece with a 20,000 Rpm
motor. Meaning the motor is powerful enough for a 1:1 nose cone or contra angle, making
it useful on procedures for small animals such as rabbits, and more advanced method
such as modeling of teeth.
2. If your unit is equipped with a Piezo Scaler built into the middle white accessories line do
not worry about the pressure setting for this, as it is an electric Scaler and only uses air to
turn a switch on and off.
3. If your unit is equipped with a fiber optic high speed drill note that it has an eighteen second
delay. This is a great feature; the eighteen second time delay on the hand piece allows
you to use the drill as a light wand.
4. The 3 Way syringe is used by depressing the right button for a burst of air, the left button
for a stream of water, both buttons depressed will produce a mist.
