Vollrath 0644N Tomato Pro Tomato Slicer Instruction Manual

Important Information

This manual provides instructions for blade replacement and adjustment for Vollrath Tomato Pro, Econo Pro, and Tomato King slicers. Warning: Blades are extremely sharp and can cause severe injury or amputation. Only trained personnel should perform maintenance. Always wash new blades with warm, soapy water to remove the protective oil film before installation.

Replacing Blade Assembly

It is recommended to change the complete blade assembly rather than individual blades to prevent breakage. Never mix old and new blades in the same assembly.

1. Prepare a flat, dry workspace.
2. For Tomato King: Close the pusher head so fingers rest against the pin stop.
3. For Tomato Pro and Econo Pro: Pull the pusher head assembly back against the back stop.
4. Remove the four blade block screws (two at each end). Retain the rubber seals mounted on the screws between the blade blocks and the casting.
5. Dispose of used blades and assemblies properly.

Adjustments

Pusher head fingers must never contact the blades. If fingers are nicked or burred, smooth them with a small flat file. Ensure spaces between fingers are uniform.

Pusher Head Finger Alignment

If fingers are not aligned between blades:

• Insert a screwdriver between the slots in the Pusher Head Assembly.
• Gently tap the screwdriver up or down to shift the fingers until they slide effortlessly through the blades.
• Repeat this process from the back side of the equipment if necessary.

Pusher Head Assembly Adjustment

If further adjustment is needed, loosen the set screws on the guide rods. Push or pull the guide rod to relocate the assembly, then tighten the set screws.

Tightening the Blades

Blades must be tightened in an alternating sequence to ensure even tension:

1. Center the blade assembly between the casting end-posts, leaving a gap of air space between the blade block and post.
2. Tighten screws one-half turn at a time in this order: Top Right, Bottom Left, Bottom Right, Top Left.
3. Repeat until tight. Check tension by strumming the dull side of the blade to ensure uniform vibration.
