Installation & Assembly
The unit is shipped with components packed separately. Follow these steps for assembly:


- Feet: Lay the unit on its side and screw in the adjustable feet. The unit must be level and used with feet attached.
- Components: Remove the butter roller, butter pan, top panel, and bottom panel.
- Conveyor: Install the conveyor cassette by placing locating pins into the hanger brackets. Push gently to engage the drive gear.
- Reassembly: Replace the bottom panel, top panel, butter pan, and butter roller in order.
Non-stick Sheet Installation
It is highly recommended to install the non-stick sheet to prevent buns from sticking and burning.

- Lay the sheet flat and measure 2 inches from the end.
- Notch the corners at 45 degrees and fold a 2-inch flap.
- Remove the bun feeder chute.
- Slip the 2-inch fold under the retainer bracket at the rear.
- Bring the sheet forward and smooth it against the grill plate.
- Reinstall the feeder chute.
Operating Instructions
Follow these steps for daily operation:


- Preheat: Turn on the main switch. Wait 15-20 minutes for 208/240V models or 20-30 minutes for 120V models.
- Settings: Set temperature to approx. 400°F (scale 6-7). If using a non-stick sheet, increase to approx. 450°F (scale 6.5). Set conveyor speed between 4 and 6.
- Oil: Fill the butter tray 2/3 full with high-quality edible oil. Turn on the butter roller.
- Toasting: Slide the sliced side of the bun onto the butter roller, then drop it into the feeder chute.
Conveyor Adjustment
If toasting is not optimal, adjust the conveyor position:

- Switch off and cool the unit.
- Remove the butter roller, tray, feed chute, and panels.
- Remove the conveyor cassette.
- Loosen the hanger adjustment brackets and move them equally towards the grill plate in 1/8-inch increments.
- Retighten screws and adjust drive gear engagement bolts if necessary.
Cleaning & Maintenance

- Conveyor: Clean the conveyor cassette in a sink with regular detergent. Lubricate chains after cleaning with suitable toaster oil.
- Grill Plate: Clean with a suitable grill plate scourer. Apply a light film of toaster oil after drying.
- Replacement: Replace the non-stick sheet every 30 days or when buns start sticking.
