9.23 Feed Screw Cleaning and Replacement

9.23.1 Prepare for Feed Screw Removal

WARNING

This procedure is done in the hot condition. Wear appropriate personal

protective equipment such as heat resistant gloves and goggles or a face

shield. Failure to do so can result in serious injury.

1. Move the machine to a work surface. See “Move the E-Multi Injection Unit

for Maintenance” on page 9-9.

2. Remove front and rear guards.

1. Rear guard
2. Front guard

3. Clean the nozzle and barrel area. Remove any plastic residue, using soft

brass tools only.

4. Remove the nozzle tip and clean plastic from the nozzle opening and

inner cone.
