Restoring Komatsu LW100-1 Dash Labels and Instrument Panel Clarity

[MikePhua]

The Komatsu LW100-1 and Its Place in Loader History
The Komatsu LW100-1 was introduced during the late 1980s as part of Komatsu’s push to expand its wheel loader offerings into mid-size utility applications. With an operating weight of approximately 17,000 lbs and a bucket capacity around 2.0 cubic yards, the LW100-1 was designed for versatility—handling everything from aggregate loading to light construction site prep. It featured a robust mechanical drivetrain, a torque converter transmission, and a cab layout that emphasized visibility and operator comfort.
Komatsu, founded in 1921, had already established itself globally in the dozer and excavator markets. The LW series helped round out its loader lineup, especially in regions where compact maneuverability and mechanical simplicity were valued. Though production numbers for the LW100-1 were modest compared to flagship models, it remains a reliable machine in many fleets, particularly in rural and municipal operations.
The Importance of Dash Decals and Instrument Panel Legibility
Dash decals—also known as instrument panel overlays or control labels—play a critical role in safe and efficient machine operation. These decals identify switches, gauges, warning lights, and control levers. Over time, exposure to sunlight, vibration, cleaning solvents, and general wear can cause these labels to fade, peel, or become unreadable.
In older machines like the LW100-1, the loss of dash decal clarity can lead to:

• Misidentification of critical controls (e.g., hydraulic lockout, parking brake)
  
• Confusion during startup or shutdown procedures
  
• Difficulty interpreting warning indicators or fault codes
  
• Increased training time for new operators
  
• Safety risks during emergency response or troubleshooting
  

A contractor in Alberta once had a loader operator mistakenly engage the hydraulic lockout instead of the auxiliary light switch due to faded labeling. The result was a stalled bucket during a tight loading cycle, causing a delay and minor damage to a stockpile wall.
Reproducing and Replacing Dash Decals
For legacy machines like the LW100-1, OEM decals may no longer be available through standard dealer channels. However, several strategies exist for reproduction:

• Custom Vinyl Printing
  • Use high-resolution scans or photos of original decals
    
  • Print on UV-resistant vinyl with adhesive backing
    
  • Laminate for durability and solvent resistance
    
• Laser-Etched Panels
  • Create aluminum or polycarbonate overlays with etched labels
    
  • Ideal for high-heat or high-vibration environments
    
• Aftermarket Restoration Kits
  • Some suppliers specialize in vintage equipment decals
    
  • May include full dash overlays, warning labels, and safety placards
    
• DIY Solutions
  

• Use vector design software to recreate label layouts
  
• Print on transparent film and apply over cleaned surfaces
  
• Seal edges with clear coat or decal adhesive
  

Recommended materials include 3M Controltac vinyl, Oracal 651 for outdoor durability, and Lexan overlays for abrasion resistance. Label fonts should match original Komatsu styling for authenticity and readability.
A restorer in Chile recreated his LW100-1’s dash using a combination of scanned manuals and photos from similar machines. He printed the decals on matte vinyl and applied them with a heat gun for contouring. The result was a clean, legible panel that matched the original layout.
Instrument Panel Cleaning and Preparation
Before applying new decals:

• Remove old adhesive and residue using citrus-based cleaner or isopropyl alcohol
  
• Sand lightly if surface is oxidized or uneven
  
• Wipe clean and allow to dry completely
  
• Align new decals using masking tape guides
  
• Apply slowly to avoid bubbles or misalignment
  
• Seal with clear protective film if needed
  

Avoid harsh solvents like acetone or brake cleaner, which can damage plastic surfaces and wiring insulation. Use nitrile gloves to prevent oil transfer during application.
A technician in Texas added a layer of anti-glare film over his loader’s restored dash to improve visibility during bright daylight operations. The film also protected the decals from UV degradation and dust buildup.
Preserving Label Integrity Over Time
To extend the life of dash decals:

• Park equipment under cover or use cab sunshades
  
• Clean with mild soap and water, avoiding abrasive brushes
  
• Avoid pressure washing near the instrument panel
  
• Inspect decals quarterly and replace damaged sections promptly
  
• Keep a digital archive of decal layouts for future reproduction
  

A fleet manager in Ontario created a decal database for all legacy machines in his yard. This allowed quick reordering and reduced downtime when panels needed restoration.
Conclusion and Recommendations
Restoring dash decals on the Komatsu LW100-1 is more than cosmetic—it’s a functional upgrade that improves safety, efficiency, and operator confidence. With careful reproduction and installation, even decades-old loaders can regain the clarity and professionalism of their original design.
Recommendations include:

• Use high-quality vinyl or etched materials for durability
  
• Clean and prep surfaces thoroughly before application
  
• Match original layout and font for authenticity
  
• Archive decal designs for future use
  
• Train operators to recognize and report fading or damage
  

With attention to detail and the right materials, the LW100-1’s dashboard can once again serve as a clear, reliable interface between machine and operator—preserving Komatsu’s legacy of practical, operator-focused design.
