Before powering up the dispensing system, follow the steps below to make sure there is sufficient
clearance for the dispensing head to operate in the dispensing chamber.
CAUTION!
The following procedures should only be performed by a trained
service technician.
To check Dispensing Head clearance:

dispensing chamber making sure that it does not encounter any obstacles during its travel.
2. Make sure the pneumatic and electrical cables do not impede the dispensing head travel and
are not in danger of being pinched or snagged.
3. Check the dispensing valve and bracket to make sure that it is mounted securely.
4. Close the dispensing system hood.
