➊ O-rings
➋ Retention sleeve
➌ Spray regulation ring (for RQ-14, RQ-34)

10

Cooling water lines

All Roto Quick couplings are equipped with a non-retraction valve which prevents contaminated cooling water
from being sucked back into the turbine and the turbine hose.
The non-retraction valve– is integrated in the cooling water supply system.
In the event of blocked or incorrectly routed cooling water lines, please contact an authorized W&H service
partner (see page 31).

The cooling water lines must not be cleaned with sharp objects!
(This could damage the sealing element and prevent the non-retraction valve from working.)

4. Operation – Connecting the Roto Quick coupling

➊ Connect the Roto Quick coupling to the turbine hose.
➋ Firmly tighten the union nut of the turbine hose by hand in

a clockwise direction to ensure there are no leaks.

This method of assembly provides a connection for drive air, chip air, water and return air (only for RM).

12

Operation – Disconnecting the Roto Quick coupling

➊ Unscrew the union nut of the turbine hose by hand

in an anticlockwise direction.

➋ Carefully remove the Roto Quick coupling from

the turbine hose.

13

Checking the Roto Quick coupling for leaks

> Check for leaks between the Roto Quick coupling and turbine hose.
> Block the water outlet on the tip of the Roto Quick coupling using a piece of rubber or leather.
> Turn on the spray water. After being blocked for 10 seconds, no water must escape between the coupling and turbine

hose or at the spray regulator.

> If you observe problems (e. g. vibrations, unusual noise and/or leaks), stop the Roto Quick coupling immediately and

contact an authorized W&H service partner (see Page 31).

14

Operation – Changing air driven instruments

> Observe the instructions in the relevant instructions for use.
> Only connect air driven instruments with Roto Quick connections to the Roto Quick coupling.

The user accepts sole responsibility if other air driven instruments are used.
We accept no liability in such cases.

15

Operation – Changing air driven instruments

Never connect or disconnect the air driven instrument while the system is running!

> Attach the air driven instrument onto the Roto Quick coupling until it audibly engages.
> Pull axially along the Roto Quick coupling to check that the air driven instrument is securely attached.
> Pull the retention sleeve of the Roto Quick coupling back.
> To disconnect the air driven instrument, pull it off in axial direction.

16

Regulating the spray water

For Roto Quick couplings RQ-14 and RQ-34: Adjustment directly at the spray adjuster ring or at the adjustable valves of the
unit. Roto Quick couplings RQ-03, RQ-04 and RQ-24 can only be adjusted at the unit.

Minimum spray flow:
Maximum spray flow: Turn the spray adjuster ring to the right or left.

The water flow can only be varied using this spray adjuster ring. It cannot be stopped completely.

Line marking on the spray adjuster ring and point on the retention sleeve correspond with each other.

17

Test run
