Master On/Off Toggle

The master on/off toggle
(see Figure 3) turns air, water, and
electricity on or off to the system.

CAUTION

The MASTER ON/OFF TOGGLE should be
in the OFF (0) position whenever the unit
is not in use.

This will prevent the possibility of water
damage should a leak occur while the unit is
unattended.

Making sure the unit is off will also
prevent the possibility of self-activation
and the resulting burn-out of your
electrical accessories.

came with your handpiece for the dynamic drive
air pressure specification.

Use a 3⁄32" hex key to complete this adjustment.

2. Locate the drive air gauge on the front of the
control head (see Figure 2 on page 2).

3. Move the wet/dry toggle on the foot control
(see Figure 6 on page 9) to the OFF position,
away from the blue dot).

4. Turn the drive air control clockwise until the
valve seats.

5. Fully depress the foot control disc.

6. While running the handpiece, watch the
drive air gauge and adjust the handpiece
dynamic drive air pressure to meet
manufacturer’s specifications.

• Turn the drive air control counterclockwise to

increase drive air pressure flow.

• Turn the control clockwise to decrease flow.

NOTE

Do not turn the control counterclockwise
beyond the point where the drive air
pressure no longer increases. The control
adjustment screw may come completely out
of the unit.

7. Repeat steps 1 through 6 for each handpiece.
