Steps 1 to 4 for Barrel and Screw Replacement

Preparation & Safety Gear

Gather necessary tools (e.g., hot gloves, protective sleeves) and set up your lifting device. Make sure to lock out the machine for safety.

Step 1: Remove the Purge Guard

Start by removing the purge guard with four Phillips head screws, detaching it to access the inner assembly.

Step 2: Detach the Barrel Cover

Unscrew the tray and covers on both sides of the machine. This provides access to the barrel and internal heater bands.

On the non-operator side, remove the bottom barrel cover by sliding it forward. Loosen the seal around the heater cables and thermocouples by releasing the lock nut.

Step 4: Lift the Barrel Cover and Remove

With everything loosened, lift the barrel cover completely to access the barrel and screw assembly for replacement.
