Topcon System Five, Smooth Trac 2004 Operators Manual

If you are running a Topcon paver with System Five and Smooth Trac gear, you have seen what happens when a control box starts hunting or a sonic tracker gives bad readings. Without the factory document, you chase ghosts. This is the Topcon System Five, Smooth Trac 2004 Operators Manual – 204 pages of OEM content, not a third-party rehash. I have seen aftermarket manuals leave out the deadband settings for slope control, and then you wonder why the mat looks like a roller coaster. This one has it all: original part number 7010-0341, Rev F, April 2004. You want the real thing, not a scan of a scan.

Sonic Tracker II: Getting the Footprint Right

Chapter 2 breaks down how a sonic tracker works – the “working window” and the sonic footprint. Most guys set a sonic tracker six inches off the stringline and call it good. Page 73 (if I recall) tells you the exact distance for the L-bar depending on whether you are tracking sub-grade or joint matching. Temperature changes? The manual covers how the sonic signal drifts in heat. You will find the factory-recommended placement for the temperature bail. Skip that, and your grade will drift by noon.

Control Box Menu Settings – Why You Need Them

Chapter 4 is the meat of this manual. The Performance Menu includes Gain (Elevation), Gain (Slope Control), Valve Offset, Averaging, Deadband Elevation, Deadband Slope, Beeper Alarm, Unit, and Test. If you have ever had a paver that oscillates instead of holding grade, you adjust the deadband. But what value? The manual gives the default settings and explains how to tune for mix type. I have seen guys crank the gain to max thinking it fixes things – then the screed porpoises. Read the table on page 42 (I think) before you touch that knob.

Troubleshooting Symptoms – 13 Control Box Issues

Chapter 9 lists 13 control box symptoms, 5 tracker symptoms, 5 slope sensor symptoms, and 5 SAS symptoms. Each symptom has a cause and a fix. Symptom 3 for the control box: display dims or flickers. The manual tells you to check the light sensor and power switch connection. Not guess – check. That is what you get from an OEM manual. If you have a Sonic Tracker II that won’t lock, the tracker symptom 2 might point to a dirty transducer. They give the part number for the replacement. You will find it in Chapter 8 under Sonic Tracker II Transducer Replacement.

Paving Principles – What Affects Mat Quality

Chapter 2 covers how a screed works – tow point force (P), head of material (M), reaction under screed (R), weight of screed (W), and quality of base. It explains how truck exchange affects tow point force. Mix temperature and gradation effects are spelled out. If you are paving city streets through intersections, Chapter 7 gives two methods. Method 1 uses sonics, Method 2 uses cross slope. The manual explains when to switch from elevation control to slope control so you don’t bury the grade stake. Rolling techniques are in there too – not a bad read for the roller operator.

Stringline Setup – Cut/Fill Lath Details

Chapter 3 walks you through setting surface stringline, elevated stringline, and projected slope stringline. It tells you how to make a cut/fill lath and attach the stringline to the grade stake. If you run a paver on a jobsite where the stringline sags, the manual covers verifying grade. You will also find the proper tension – not specified in aftermarket copies. I have seen a sagging line ruin a 200-foot stretch of curb and gutter. This manual prevents that.

Source Authenticity – OEM vs Aftermarket

This is a Topcon factory manual. The inside cover says “©Copyright Topcon Positioning Systems, Inc.” and the part number is real. Aftermarket manuals often omit the Safety Precautions appendix (Appendix A) and the Limited Warranty terms (Appendix B). This one includes both. If you need to know the return policy on electronic components, it is on page 199. I have dealt with counterfeit manuals that had wrong torque values for the mounting bolts – never again. Stick with OEM.

External reference: the Anti-lock Braking System (ABS) and Manual Transmission definitions are useful for understanding vehicle dynamics, but for paver control this manual is what you need.

Will this manual help me troubleshoot a control box error code?

Yes. Chapter 9 lists 13 control box symptoms, each with a cause and fix. No error codes – this is pre-CAN bus – but the symptoms cover display issues, beeper failures, and grade drift.

What safety precautions are included?

Appendix A (Safety Precautions) covers general machine safety, electrical hazards, and proper shutdown procedures. It also warns against operating the paver with damaged sensors. The manual stresses the importance of keeping the control box dry – moisture can short the grade adjustment knob. There is a section on safe stringline tension to prevent snap-back injuries. I have seen a stringline whip across a crew – not pretty.
