6.7. Replacing Oil by a New Type

If you want to switch over to a new type of oil, you will have to drain the current oil from the system. If you do not drain it, the current oil will mix with the new oil.

1. Position the unit on a bowling lane (see 'Mounting the Unit onto a Bowling Lane').
2. Make sure the start indicator  within the start button  burns continuously. (If this is not the case, go to 'TROUBLE CHECKS').
3. Press the illuminated green start button . The air pump will be switched on and after a few seconds the unit will start moving. The start indicator  will flash.
4. As soon as the unit starts moving, briefly press the start button  to temporarily halt the conditioning session; the air pump will stay on.
5. From the left spray nozzle, disconnect the transparent tube. To do this, push the tube into the fastener on the nozzle, hold back the quick-disconnect ring, then pull back the tube out of the fastener.
6. The oil will now pour out of the tube under slight pressure. Wait until no more fluid comes out.
7. Connect the tube back to the nozzle. Press the tube firmly into the fastener, then pull it back to secure the connection.
8. Repeat items 5, 6 and 7 for the right spray nozzle.
9. Fill the oil tank with at the most two liters (0.4 gallon) of the new oil (see also 'Supplying Oil' on page 11).
10. The air in the oil tubes must now be thoroughly drained. This is described in 'Draining Air from the Oil Tubes'.
