B.a.r Cargolift Troubleshooting Manual

Let’s cut through the noise. You’ve got a B.a.r Cargolift on the lift, and it’s giving you grief. No response to controls, lift function slow, pump running but not lifting. You’ve poked at fuses, swapped relays, and you’re guessing. Guessing costs you billable hours and parts returns. This B.a.r Cargolift Troubleshooting Manual is 15 pages of factory diagnostics that gets you straight to the cause. No aftermarket interpretations. No missing steps. The OEM fault table and the fix are right there. Page 46 shows you exactly what’s wrong, what causes it, and what to do.

Possible Faults and Remedies: The Core of This Manual

Page 46 lays out the troubleshooting table. Three columns: fault, cause, remedy. For example: “Cargolift responds to neither hand nor foot control – audible.” Causes: cab switch not engaged or defective, control circuit fuse blown, control wire broken. Remedy: replace fuse (max 7.5 A), inspect and repair wiring. Another one: “Lift function not working or slow – pump motor runs normal.” That points to low oil in the tank (pump sucking air), a defective pump, or the pressure relief valve set too low. Each entry is a direct path from symptom to fix. That’s what you need when the platform is halfway up and the customer is watching.

Hydraulic System Checks After Repairs

Here’s a detail that aftermarket garbage leaves out. After any hydraulic repair performed with the platform closed, you must first run “Heave” and “Close” to refill the cylinders with oil so they accept the platform’s weight. Skip that step and you’ll blow seals or get air locks. This manual warns that the cylinders must übernehmen the Eigengewicht (deadweight) of the platform. That’s on the same page. Proper procedure, factory-stamped. If you’re working on lift systems, you might also need the Volvo BM Michigan 850 1995 Troubleshooting Manual for related hydraulic diagnostics.

Electrical and Battery Diagnostics: Real-World Causes

Page 47 covers what happens when the battery is weak or the charging system fails. The table lists “Battery poorly charged” and “Battery discharged / generator too weak / main switch in battery box oxidized”. The remedy includes load-testing individual cells, checking charge-line fuses in both truck and trailer, inspecting charge-line connectors, and possibly installing a larger conductor cross-section for the trailer. A temporary workaround: run the vehicle engine. The manual tells you to replace the generator with a stronger one. None of this is generic advice – it’s B.a.r’s own engineering countermeasures. For a broader understanding of mechanical power transfer, see the Manual Transmission page on Wikipedia.

Why 15 Pages Is Enough

You don’t need a 600-page encyclopedia for a Cargolift. This manual is laser-focused: every page is a fault table or a critical note. The table continues on page 47 with pump motor running slower than normal, battery issues, and cab switch checks. There’s no theory, no exploded view of the whole truck. If you need background theory on manual drivelines, read Manual Transmission documentation. But for this specific lift, the 15 pages are all you need. A quick reference that lives on the bench or in your tablet.

Source Authenticity: This Is the OEM Document

I trust factory manuals because I’ve been burned by third-party reprints that swap torque values or omit steps. This is the original B.a.r document, scanned from the German factory source. Part number 01.123831 appears on the pages. The language is German, but the tables are universal. If you’ve ever used a Volvo BM Michigan D6B-D16B Troubleshooting Manual – 144 Pages, you know the value of OEM originals. For heavy hydraulics, also check the Hitachi 140W-3 2007 Troubleshooting Manual – 618 Pages if you’re into larger excavators. But for the Cargolift, this is the only factory source you need.

FAQ

Does this manual cover the electrical system of the Cargolift?

Yes. The troubleshooting table includes faults for control circuit fuses (max 7.5 A), wiring breaks, cab switch, battery charge, generator output, and main switch oxidation. Page 46 and 47 cover electrical and battery diagnostics.

How many pages is the manual?

15 pages.

Is this manual in English?

No, it’s the original German factory document (titled “Störung und Behebung”). However, the fault/cause/remedy tables are numeric and symbol-heavy, and the technical terms are clear with minimal translation. For those comfortable with German, it’s a direct read; for others, the table structure still delivers actionable info.

Can I use this manual for a different brand of lift?

Only if you’re using a B.a.r Cargolift. The hydraulic and electrical schematics, component part numbers, and control logic are specific to this model. Generic troubleshooting won’t give you the right pressure relief valve settings or fuse ratings. Stick to the right manual.
