Guide to Locking Tabs on Each Side of Die Cutting Machines

If you own a manual, electric, mini, or portable die cutting machine, you may have noticed small levers, clips, or tabs on the left and right sides of the unit. These are the locking tabs on each side, and they play a vital role in keeping your machine steady and safe during cutting and embossing. While they may look like simple hardware, these tabs are part of the machine’s stability system.

This guide explains what locking tabs on each side do, how they differ from fold-down storage features, and how to inspect, maintain, and use them safely. Whether you are a card maker, scrapbooker, or small craft business owner, understanding these small components can help you get cleaner cuts and avoid unnecessary wear.

We will focus on general principles that apply to many home and hobby die cutting machines. Because designs vary, always consult your machine’s manual for specific instructions. This article does not replace manufacturer guidance.

Quick Answer

Locking tabs on each side secure a die cutting machine in its operating position. They prevent shifting, maintain plate alignment, and help ensure even pressure. Inspect them for wear, keep them clean, and engage both tabs fully before cutting.

How Locking Tabs on Each Side Stabilize Your Die Cutting Machine

Locking tabs on each side are mechanical components that hold the machine in a fixed, stable configuration while you apply pressure. They are usually located near the base, frame, or hinge area of the machine. When engaged, they create a rigid connection that reduces movement, vibration, and the chance of the machine tipping or sliding on your work surface.

In many manual die cutting machines, the side tabs lock the machine in its open, operating position. Without them, the machine might fold or collapse under the force of the handle. In some electric and portable models, the tabs may clamp the machine to a table or lock the housing together. The exact design varies, but the goal is the same: stability during operation.

When both tabs are properly engaged, they help maintain alignment between the rollers, plates, and cutting dies. This alignment is critical for even pressure. If one tab is loose or disengaged, the machine may shift slightly, causing incomplete cuts, damaged dies, or extra wear on internal parts. Over time, ignoring a faulty tab can lead to costly repairs.

Purpose of Side Locking Tabs

The main purpose of locking tabs on each side is to secure and stabilize the machine during operation. They serve several related functions:

• Prevent the machine from rocking, sliding, or tipping as you turn the handle or run the motor.
• Hold the machine in its correct operating position, especially if it has a folding frame.
• Maintain consistent pressure across the cutting plates for cleaner cuts and embossing.
• Reduce vibration that can loosen other fasteners or misalign the rollers.
• Protect the user by keeping hands and fingers away from moving parts that might shift unexpectedly.

Not every die cutting machine uses side locking tabs. Some rely on a sturdy base, non-slip feet, or a different clamping system. If your machine has them, they are an important part of its safe operation.

How Locking Tabs Differ from Fold-Down Storage Features

It is easy to confuse locking tabs with the latches or hinges that allow a machine to fold down for storage. While both may be on the sides or base, they serve different purposes. Fold-down storage features are designed to reduce the machine’s footprint when it is not in use. They may include a latch that keeps the folded machine closed during transport.

Locking tabs for operation, by contrast, are engaged while you are cutting or embossing. Their job is to keep the machine rigid and stable, not to save space. On some machines, a single mechanism may serve both roles, but the operational locking function is the one that affects cut quality and safety. Always check your manual to understand which tabs lock the machine for use and which ones secure it for storage.

If you release the operating locking tabs while cutting, the machine may shift or fold. If you force a storage latch into the wrong position, you may damage the mechanism. Knowing the difference helps you avoid mistakes.

Inspecting Locking Tabs on Each Side

Regular inspection of locking tabs on each side can prevent poor cutting results and unsafe conditions. A worn or damaged tab may not hold the machine securely, even if it looks fine at a glance. Make inspection a habit before starting a new project or at least on a regular schedule.

Visual Checks

Begin with a careful visual examination. Look at both tabs and the areas where they connect to the machine. Check for:

• Cracks, chips, or bends in the tab itself.
• Rust, corrosion, or discoloration that could indicate moisture exposure.
• Debris such as paper dust, adhesive residue, or bits of craft material lodged in the mechanism.
• Missing springs, pins, screws, or retaining clips.
• Uneven wear between the left and right tabs.

If you see any damage, do not use the machine until you have addressed it. A broken tab can fail suddenly under pressure.

Movement and Engagement Tests

With the machine turned off and, for electric models, unplugged, gently move each tab through its full range of motion. It should move smoothly without grinding or excessive force. When you engage the tab, it should click, snap, or tighten into a secure position. Test both tabs together to see if they engage evenly.

Some play or slight movement may be normal, but excessive wobble suggests wear. If one tab feels much looser than the other, that side may not be providing proper support. Do not try to bend or force a tab into position; that can cause permanent damage.

Alignment and Pressure Checks

After engaging both locking tabs, place the machine on a stable surface and try to move it side to side. It should feel solid, with little or no shifting. You can also run a test cut or emboss with scrap material. If the result is uneven—for example, one side of the die cuts deeper than the other—a locking tab may not be holding the machine correctly.

Remember that other factors, such as worn cutting plates or incorrect shims, can also cause uneven pressure. If you suspect the tabs, inspect them first before adjusting other variables.

Maintaining Locking Tabs for Reliable Operation

Maintenance is simple but important. Keeping the tabs clean and free of debris helps them engage fully and last longer. Always follow your machine’s manual for specific care instructions, because materials and finishes vary.

Cleaning and Debris Removal

Before cleaning, unplug electric machines and ensure manual machines are in a safe, resting position. Use a soft brush, a dry cloth, or a slightly damp cloth to remove dust and small particles. If the tabs are removable and the manufacturer allows it, you can wash them with mild soap and water, then dry them completely before reinstalling.

Avoid harsh solvents, abrasive cleaners, or metal tools that could scratch or weaken the tabs. Do not pour water or cleaning solution directly into the machine’s openings. For stubborn adhesive residue, a small amount of isopropyl alcohol on a cloth may help, but test it on a hidden area first and check the manual for restrictions.

Lubrication and Wear Parts

Some locking tabs benefit from a small amount of light lubrication, but only if the manufacturer recommends it. Using the wrong lubricant can attract dust, degrade plastic, or stain your materials. If lubrication is advised, apply a tiny amount to the pivot point or sliding surface with a cotton swab. Wipe away any excess.

Inspect any springs, screws, or rubber grips associated with the tabs. If a spring has stretched or a screw is stripped, the tab may not hold securely. Replacement parts may be available from the manufacturer for some models. If the tab is integrated into the machine’s frame and cannot be replaced separately, contact the manufacturer for service options.

Safe Use of Locking Tabs During Die Cutting

Safe operation starts with understanding how your locking tabs work. The following general guidelines apply to many home and hobby machines, but your manual is the final authority.

Before You Start

Place the machine on a flat, stable surface. Engage both locking tabs fully. Check that they are not loose or partially engaged. For electric machines, make sure the power cord is not damaged and that the machine is turned off before you plug it in. Keep fingers, hair, and loose clothing away from the tab mechanisms and moving parts.

During Operation

Apply pressure smoothly. If you feel unusual resistance or hear a snapping sound, stop and inspect the machine. Do not force the handle or motor. Watch for any shifting of the machine as you work. If the machine moves despite the tabs being engaged, stop and investigate. Continued use could damage the machine or cause injury.

After Use and Storage

When you finish crafting, clean debris from the tabs and the surrounding area. If your machine folds for storage, release the operating locking tabs according to the manual before folding. Do not force the machine closed if a tab is still engaged. Store the machine in a dry place, away from extreme temperatures and moisture.

If the manual says to leave the tabs engaged for storage, follow that instruction. Some machines are designed to be stored with the tabs locked to protect the mechanism.

Common Problems and Troubleshooting

Even well-maintained locking tabs can develop issues. Here are some common problems and general steps you can take.

Tabs That Won’t Engage

If a tab will not engage, first check for debris or misalignment. Clean the area and look for bent pins or foreign objects. Make sure the machine is in the correct operating position. If the tab still will not engage, do not force it. The mechanism may be damaged, or the machine may not be fully unfolded. Consult your manual or contact the manufacturer.

Loose or Wobbly Tabs

Some slight movement is normal, but a tab that wobbles excessively may have a worn spring, a loose screw, or a cracked housing. Check all fasteners and tighten them if the manual allows. Do not overtighten, as this can strip threads or crack plastic. If the tab remains loose, it may need replacement or professional service.

Broken or Missing Tabs

If a locking tab is broken or missing, stop using the machine immediately. The remaining tab may not provide enough stability, and the machine could shift unexpectedly. Do not try to substitute a homemade part or tape the tab in place. Contact the manufacturer for replacement parts or service advice. If the machine is under warranty, unauthorized repairs may void coverage.

When to Seek Manufacturer Guidance

Because die cutting machines vary widely, some maintenance and repair tasks are best left to the manufacturer or an authorized service provider. Seek guidance if:

• You are unsure whether a tab is supposed to be lubricated.
• A tab is cracked, bent, or missing.
• The machine still wobbles after you have engaged both tabs correctly.
• You need replacement parts.
• The machine is under warranty.
• You cannot find clear instructions in the manual.

Do not attempt to disassemble the machine beyond what the manual describes. Internal springs and linkages can be difficult to reassemble correctly and may cause injury if they release suddenly.
