Barber-greene BG220B, BG240B, BG260B, BG270B 1993 Operators Manual

Running a six-bay shop in San Antonio, I’ve seen too many paving jobs go sideways because someone tried to wing it on a Barber-greene paver without the book. This 1993 Operators Manual for the BG220B, BG240B, BG260B, and BG270B rubber-tired asphalt pavers is exactly what you need if you’re tired of guessing which control does what or why the screed won’t lay a mat right. It’s 129 pages of factory-issued documentation, not some aftermarket reprint that leaves out critical torque values. Barber-greene BG220B, BG240B, BG260B, BG270B 1993 Operators Manual – that’s the title you want in your PDF reader when you’re sitting in the cab scratching your head.

Safety: The First 20 Pages Pay Off

Section A of this manual runs from page 1 through safety warnings and receiving instructions. Before you even think about unloading the machine, it tells you to inspect for transit damage and contact your nearest Barber-Greene distributor for start-up support. I’ve had guys skip this, then spend a full day trying to fire up a paver with a cracked hydraulic line. The manual’s clear: check against the freight bill, note any loss, and file a claim immediately. That’s shop-floor advice, not legal boilerplate. It also stresses that only authorized Barber-Greene replacement parts should be used because those parts are machined to specific tolerances. You want a cheap aftermarket sprocket? That’s your call, but don’t blame the manual when it fails.

B Specifications: What You Need Before You Touch a Wrench

Section B covers machine specifications. You’ll find engine ratings, hydraulic system pressures, travel speeds, and capacities for the BG220B, BG240B, BG260B, and BG270B. Need the charge pressure for the propel system? It’s in there. Fluid capacities are listed in U.S. quarts and gallons – none of that mixed-unit nonsense. If you’re rebuilding a final drive or swapping a pump, you pull this section open and verify the numbers. I’ve seen cross-threaded fittings happen because a tech used a spec from a third-party website. Don’t be that guy. Stick with the factory data from this manual.

Use of Controls: Page 40 and Beyond

Section D – Use of Controls – is where the manual earns its keep. It walks through every lever, switch, and pedal on the paver. You get the step-by-step sequence for starting the engine, engaging the augers, and setting the feeder gates. There’s a dedicated subsection for the grade controls (Section E) and grade control setup/operation (Section F). If you’re not familiar with the slope sensor or the sonic tracer, this is where you’ll learn the correct adjustment procedure. Don’t skip Section F – I’ve watched crews spend an hour trying to dial in a mat because they didn’t understand the grade control initialization sequence. The manual shows you the exact button presses and calibration steps. It’s in black and white.

Screed Setup: Standard and Extend-A-Mat

Section G covers standard screed setup and operation. Section H goes into the Extend-A-Mat screed. These aren’t generic instructions – they’re specific to the Barber-Greene BG240B and BG260B models that use the Extend-A-Mat system. You get the crown adjustment procedure, the heater switch sequence, and the vibration frequency settings. Page numbers? The screed sections start around page 70 [DATA NEEDED] but the actual page counts depend on the edition. What matters is the content: torque specs for the screed mounting bolts, the correct grease points for the extendable sections, and the troubleshooting table in Section K. That troubleshooting table alone is worth the price if you’ve ever had a screed that won’t heat evenly or a mat that pulls apart at the joint.

Lubrication and Maintenance: The Difference Between a Day’s Work and a Breakdown

Section J – Lubrication – lists every grease fitting, oil change interval, and filter part number. The manual specifies the correct SAE grades for different ambient temperatures. In San Antonio, we run 30-weight in winter and 40-weight in summer – you need that straight from the factory source, not from a forum post. Section K combines maintenance schedules with troubleshooting. You get a symptom-and-cause table for common problems: engine won’t start, screed lift circuit weak, grade control not tracking. Each symptom has a check sequence that starts with the simplest cause (low fluid, blown fuse) and works up to mechanical failure. That structure saves hours of diagnostic time. Pair this manual with the related Barber-Greene BG240B Asphalt Paver Parts Manual if you need exploded views and part numbers. For earlier models, the Barber-greene SB-131 Operators Manual – Factory Specs for Asphalt Paver or Barber-greene SB-41 1965 Operators Manual – Factory Specs might also be relevant, but the B-Series rubber-tired line is its own beast. Don’t mix generations.

Why Factory OEM Beats Aftermarket

I won’t waste your time with brand names, but I will say this: aftermarket manual publishers routinely copy diagrams from older models and paste them into new documents. This manual is straight from Caterpillar’s Barber-Greene division, printed in 1993, with original artwork and step-by-step instructions that match the actual machines. The table of contents includes sections A through K, each with its own page numbering. When you see a procedure like “Setting Grade Control Sensitivity,” it’s the factory procedure, not a rephrased summary. You pay for accuracy, and that’s what you get. For background on the basic principles of a manual transmission (if your paver uses one) or general troubleshooting, check Manual Transmission and Manual Transmission – but for specific BG-series info, this is the only source you trust.

Does this manual cover the BG220B only, or all models?

It covers BG220B, BG240B, BG260B, and BG270B.

What about the hydraulic system pressures?

Section B lists charge pressure, main relief setting, and travel motor displacement. Typical charge pressure ranges from 200-300 psi, but you verify against the manual because machine variations exist. Don’t assume.

Can I use this for the Extend-A-Mat screed?

Yes. Section H is dedicated to Extend-A-Mat setup, including cylinder rod torque and wear strip replacement intervals. If you’re running a non-standard screed like the Vibratory or the OmniScreed, those are not in this manual – check the parts manual for alternate screed supplements.

Are there wiring diagrams?

This is an operators manual, not a service manual. It contains component locations and control descriptions, but not detailed schematics. For wiring, you need the Barber-Greene electrical schematic set (sold separately).

You’ve got a paving season coming up. You don’t have time to chase down specs from five different sources. This 129-page Barber-greene BG220B, BG240B, BG260B, BG270B 1993 Operators Manual puts every factory torque, fluid capacity, and control procedure in one PDF. Print the lubrication chart and tape it inside the tool box. Keep the troubleshooting table bookmarked. Access the Factory Manual and get back to laying mat.
