Last week in Part 2 we covered the cylinder drift test and the two main seal kits you might need if it fails. If you’re a roofer (or any contractor) who just bought one of these machines, this week we’re focusing on the “General” section of the AWP inspection checklist — safety decals, placards, paint, and overall appearance. On a 10-year-old 660SJ these items are quick to check and fix, but they’re some of the first things an OSHA inspector or insurance auditor will look at.
Why Decals and Appearance Matter on an Older AWP
- Safety — Decals show load limits, emergency stop procedures, and hazard warnings.
- Compliance — Jobsites and insurers require all placards to be installed, secure, and fully legible.
- Resale value — A clean, fully stickered machine sells faster and for more money.
- Quick visual clue — If the paint is peeling or decals are sun-bleached, it’s often a red flag for other maintenance issues.
Key Items to Check and Fix
- All decals/placards installed, secure, and legible
- No unauthorized modifications
- General structural condition and welds (visual check)
- All fasteners, pins, shields, and covers secure
- Paint and appearance clean and free of heavy rust or debris
- Inspection date stamped on the frame

Paint and Touch-Up – Keep It Looking Professional
While you’re doing the decals, take time to touch up any chips, scratches, or faded areas. Fresh paint protects against rust and keeps the machine looking well-maintained.

Bottom Line for Roofers
Decals and paint are relatively low-cost fixes (usually $800–$1,800 in parts plus a few hours of labor) but they’re non-negotiable for staying compliant. Knock them out during your first annual inspection (already budgeted in Part 1). A clean, fully labeled 660SJ tells your crew, your insurance company, and future buyers that this machine is taken seriously.
Next week in Part 4 (final article): We’ll cover common error codes and user codes on the 660SJ — what they mean and the quick troubleshooting steps before calling a tech.
