The WaxJet Heater Replacement Kit (part #X01162-002) contains
all of the parts needed for replacing the heater, as well as the
following instructions. Removing and replacing components of the
WaxJet Solid Wax System is a delicate task. During operation, the
Printhead is heated to approximately 135º C (275º F). Make sure
that the system is thoroughly cooled down to avoid injury. Handle
the wax hose carefully to avoid damage. Read each step carefully
and follow the prescribed sequence to avoid pitfalls. The drawings
included with these instructions and shown in this section are for
illustrative purposes and are not necessarily exact replicas of the
assemblies.
Refer to Figures 8-7 and 8-8 when using the following procedure.
Should further clarification be required, contact your Support
Representative.
