Bobcat S250 2008 Operators Manual – What You Need on the Job

If you’re running a Bobcat S250 skid-steer loader, you need the actual factory documentation, not some rehashed PDF from a third party. I’ve seen guys burn up a hydraulic pump because they guessed the wrong charge pressure or bypassed a safety interlock they didn’t understand. This Operators Manual from 2008, 146 pages, is what the factory puts in the cab. It covers the S250 equipped with the BICS™ (Bobcat Interlock Control System).

Safety Decals and Operator Warnings

The first thing you see in this manual is a stack of safety warnings that should be stenciled into your brain. Page 1 starts with the operator training requirement – if you hand the keys to someone who hasn’t read this, you’re asking for a rollover. The manual shows exactly where each decal goes on the machine and what it means. It covers ROPS/FOPS cab integrity, seat bar function, and the rule about never using the loader as a manlift. I’ve seen a guy lifted in a bucket – that’s a fatality waiting to happen. This manual tells you why, not just what.

BICS System: What the Manual Covers

Your S250 has the Bobcat Interlock Control System. This is the electronic brain that kills the hydraulics and drive when you’re not seated properly or the seat bar is up. The manual walks you through how the system works, what triggers it, and how to test it. It’s not a troubleshooting guide – that’s in the service manual – but it tells you the operational logic so you don’t mistake a safety lockout for a mechanical failure. The control system description alone is worth the access if you’ve ever had a machine that suddenly won’t move while the engine runs.

Operation Procedures – Not Just “Push This Lever”

There’s a section on daily startup checks, cold-weather operation, and proper loading techniques. It specifies the correct way to approach a pile, lift the load, and travel with the bucket low. Page 73 (I think – the page numbers shift in the Portuguese version) covers the Rated Operating Capacity (ROC) for different attachments. Exceeding that ROC is how you flip a loader. The manual gives you the numbers for the S250 with standard bucket and optional attachments. It also tells you what the Bobcat-approved attachments are – you bolt on a non-approved grapple and you’re voiding the liability chain.

Maintenance Intervals and Fluid Specs

Maintenance is covered by hour intervals – 10, 50, 100, 250, 500, 1000 hours. Each interval lists what to check, what to replace, and what torque to use. The manual specifies engine oil (diesel engine), hydraulic fluid (Bobcat Hydraulic Fluid or equivalent), and grease points. There’s a section on the air cleaner restriction indicator and how to service the cooling system. I’ve seen guys over-torque the drain plug and crack the pan – the manual doesn’t give you that specific torque for the oil pan plug, but it does give you the wheel lug nut torque and the auxiliary hydraulic coupling pressure specs. If you want the full torque tables, get the Bobcat S250 S300 2008 Service Manual. This operators manual is for daily use, not rebuilds.

3 Reasons to Use This OEM Manual Over Aftermarket Copies

First, the aftermarket reprinters often skip pages – I’ve seen them cut the safety decal section to save space, which is criminal. Second, the wiring diagrams and control logic in this manual are specific to the S250 serial number range A5GN20001 and up. Third, the BICS system description is verbatim from Bobcat Engineering – a generic manual can’t replicate that. If you need a parts breakdown, check the Bobcat S250 2006 Parts Catalog. For the earlier T190 model, the Bobcat T190 2006 Operators Manual – OEM Factory Specs is a different machine – don’t mix them up.

Transmission Details and Drivetrain

The S250 uses a hydrostatic transmission with a two-speed gearbox. The manual explains the range shift and how to engage the parking brake. If you’ve ever driven a skid-steer with a Manual Transmission in an older machine, this is different – no clutch, no gear stick. But the safety procedure for towing or moving a dead machine is covered: you need to release the hydrostatic brakes manually. The manual tells you how. Another reference for transmission basics: Manual Transmission systems in general are different from the hydrostatic drive; don’t confuse the two.

FAQ – Four Questions You Might Have

Does this manual cover the Portuguese language version only?

The manual we sell is the 2008 Bobcat S250 Operators Manual, original factory print. The OCR shows Portuguese text; that is the language of this specific PDF. If you need English, check the other options on site.

Can I use this for the S300 model?

No. The S300 has different ROC and weight. Use the correct model manual.

What is included in the 146 pages?

Safety warnings, controls description, BICS system explanation, operation procedures, daily checks, maintenance intervals (10 to 1000 hours), fluid capacities, decal locations, and an index. No wiring schematics or repair procedures – those are in the service manual.

Is the manual specific to the serial number range?

Yes. It covers S250 machines with serial number A5GN20001 and above. Earlier machines may have different control systems. Check your serial plate.

You don’t need to guess about your S250. The factory wrote this manual so operators could run the machine safely and within its limits. Access the Factory Manual and keep it in the cab – reference it before every shift change. Your machine, your crew, your liability.
