Claas Dominator 68 S Operators Manual – 282 Pages | OEM Factory Specs

Description

If you’re running a Claas Dominator 68 S Operators Manual in the field without the factory book, you’re asking for trouble. I’ve seen too many operators skip the safety decal section and end up with a shredded cutterbar or a hydraulic line that let go at the wrong moment. This 282-page manual from CLAAS gives you the exact procedures for setting up, operating, and maintaining that combine. No aftermarket approximations – OEM print start to finish.

First thing you’ll notice is the emphasis on identification. The manual walks you through every serial number location – combine, engine, cutterbar, even the maize picker head and straw chopper. If you ever need to order parts or check a recall, you can’t guess. You need the numbers. Page 26 in the General Information section lays out the identification plate and all serial number positions. Don’t skip it.

Safety Rules: What CLAAS Expects Before You Turn the Key

You’ll get a full chapter on safety – intended use, accident prevention, battery isolator switch, fire extinguisher placement, and the wheel chock procedure. The manual includes the actual safety decals with pictorials so you can verify your decals are still readable. On a combine this size, one wrong move with the front attachment can kill a helper. Read the section on leaving the combine harvester and locking the cutterbar before you step off the platform.

Specifications: Engine, Torques, and Tyre Pressures

The Specifications chapter covers the Engine – both inline power units used in the Dominator 68 S, plus the fuel tank capacity, battery specs, and ground drive. Wheel bolt tightening torques are listed right there, along with tyre pressures for every size listed in the traction wheel drive section. Need the slip clutch torque for the reel? It’s on the same page as the shear bolt values. No hunting through appendices.

Prior to Operation: 7 Critical Checks

Before you start the combine, the manual tells you exactly what to check on the operator’s platform – cab fan, air conditioning, heater, steering column adjustment, central electrics compartment, hydraulic control unit, and the floatation gauge for cutterbar springs. Each control lever is labeled in the instrument panel section. You also get the procedure for checking the returns sample and setting the cutterbar height indicator. If your combine has the optional rear ladder, that’s covered too.

Does This Manual Cover the Cutterbar?

Absolutely – and in more detail than most aftermarket guides bother with. The Operation – Cutterbar chapter walks you through attaching the cutterbar, adjusting the stripper angle, locking it (both up to and from specific serial numbers), levelling, connecting the universal drive shaft, hydraulic hoses, and the reel speed control cable. Then you get adjustments for crop dividers, crop lifters, knives (removal, installation, height adjustment, knife clip alignment, skids), reel tines, and fore-and-aft adjustment. Every adjustment has a step and often a torque value. If you need to replace a shear bolt, the spec is right there.

For combines with a Manual Transmission, the gear selection and clutch procedures are in the Driving the Combine section. That includes cold weather starting aid, starting the engine, power transmission, stopping, steering, brakes (foot brake and handbrake), and rear axle adjustment. Towing instructions are included – don’t pull a disabled combine without reading that page first.

Every operator should also review the Road Traffic Regulations section, especially if you’re moving the machine on public roads. Registration, dimensions in transport and working position, and the wheel chock requirement – it’s all there. Combine with a Manual Transmission? The gear selection procedures are detailed. Know your turning circle diameter to DIN 70020 before you pull into a narrow lane.

Frequently Asked Questions

Does this Operators Manual include torque specs for the wheel bolts?

Yes. Wheel bolt tightening torques are listed in the Specifications chapter under traction wheel drive. Use those values – don’t guess.

How do I find the combine serial number on my Dominator 68 S?

The manual shows the exact location of the identification plate, the combine serial number, and the engine serial number. It also covers the cutterbar, maize picker head, straw chopper, cab, and cutterbar trailer serial numbers. Check page 26.

What if I need to adjust the reel fore-and-aft on my cutterbar?

Turn to the Operation – Cutterbar section. The manual provides the mechanical adjustment procedure with the reel fore-and-aft adjustment steps. If your combine has electric reel speed adjustment, the cable connection is covered separately.

Can I use this manual for maintenance on the compressor-type air conditioning system?

Yes, but only for the operator’s platform cab. The manual includes a malfunction, cause, and remedy table for the air conditioning system. However, for any repairs involving refrigerant or compressor work, you should reference the separate service manual or have a certified technician handle it. This Operators Manual covers operation and basic troubleshooting, not detailed rebuild procedures.

Don’t run your Dominator 68 S without the factory guide. Every setting, every safety check, every torque value in here came from CLAAS. Access the Factory Manual and keep it in the cab where you can reach it.
