Preparation for Use
4 – 11 – 1 Compatibility check of internal spray nozzle/drill
Internal spray nozzles included with this product do not necessarily fit all drills on the market� Follow the instructions
given below for confirmation prior to use�
Failure to do so or to properly fit the internal spray nozzle into the drill may cause a saline solution leak, which will
result in problems such as rust or sudden stop of equipment during use�
* To mount the drill, refer to attached handpiece operation manual�
Instructions:
1
Attach a bottle of saline solution to the control unit�
2
Connect the internal spray nozzle into the tip of the
irrigation tube�
3
Insert the internal spray nozzle into the drill from the
back�
4
Turn the control unit power on and irrigate at
maximum flow for about 5 seconds�
Points to be checked:
●
Cleanliness of the saline solution coming out from
the drill: If solution is colored there could be rust
inside of the drill� If so replace the drill�
●
If coolant solution flow level is low, the exit point of
the nozzle may become clogged with cut bone
powder� Clean it or replace with a new nozzle�
●
No water leakage between internal spray nozzle
and drill before use: Ensure no water is leaking
from the entry point of irrigation nozzle� A broken
seal or no seal in the drill may be the cause�
Replace the drill even if its new� Saline solution
ingress into handpiece will cause malfunction�
CAUTION
●
If a malfunction is detected in use, such as a saline solution leaking from the back of the contra angle head, stop
using the handpiece and perform troubleshooting�
