Installation coolant delivery set/<strong>MQL</strong> coolant delivery unit<br />
1. The HSK holder must be clean, free of swarf and undamaged.<br />
2. Grease the O-rings prior to assembly.<br />
3. Centrally insert the complete coolant delivery set (coolant pipe,<br />
union nut and 2 O-rings) in the HSK with the assistance of the socket<br />
spanner.<br />
When inserting the <strong>MQL</strong> coolant delivery unit, it is paramount to<br />
ensure that the <strong>MQL</strong> pipe is inserted centrally and undamaged into<br />
the <strong>MQL</strong> length setting screw (do not kink).<br />
4. Screw in the coolant delivery set/coolant delivery unit and tighten (see<br />
table for torque figures)<br />
5. Check coolant pipe for radial mobility.<br />
