Linde E 20, E 25, E 30 Training Manual

You’ve got a Linde E 20, E 25, or E 30 forklift on the lift, and the wiring is a mess. Or the brakes are dragging. Or the travel speed is off. You reach for a manual, but the aftermarket one you bought online has the wrong connector pinouts and the torque values are missing. That’s a waste of time and parts. This Linde E 20, E 25, E 30 Training Manual is what Linde used to train their own techs. 98 pages of factory-specific procedures, not a third-party rehash.

Inside these 98 pages you get the same material Linde gave their shop floor. Section 3.7 covers the E 20, E 25, and E 30 Type 325 completely. Motors, wiring, adjustments, brakes, hydraulics, and battery dimensions. No guesswork. No missing pages.

Linde E 20, E 25, E 30 Training Manual – Factory Wiring Diagrams

Electrical troubleshooting on these forklifts is a nightmare without the correct wiring schematic. Aftermarket diagrams often swap pin numbers or skip revisions. This manual gives you the exact Stromlaufplan (wiring diagram) for each production period: up to 12/88, 1/89-6/89, 7/89-12/92, and from 1/93. It even includes the lighting and wiper circuit (page 18 in the original pagination). You also get the control circuit diagrams for the L1 and L4 connectors and the microswitches for curve travel (b1 and b2). If you’re chasing a no-drive or a steering fault, this is the only reference that matches the truck on your floor.

Adjustment Instructions for the U200 Control Board – How to Dial It In

One of the most common problems on these models is the travel speed and brake current settings. The manual’s Einstellanweisung (adjustment instructions) walk you through setting the null position of the travel switch (U25), checking its function, and then trimming the U200 control board. You get the exact procedures for measuring and setting Fahrstrom FS (drive current), Handbremsstrom HBS (hand brake current), Hochlaufzeit HZ (acceleration time), and Bremsstrom RS (brake current). All the setting values for the U200 are listed in a table. If you try to wing this with a generic meter and a prayer, you’ll either get a slow truck or one that jerks your operator around. Use the factory numbers.

98 Pages of Maintenance and Repair Procedures

Section 3.7.6 covers disc brakes, master cylinder, hand and foot brake arrangement, steering axle, and wheel drive. The disc brake section alone gives you the construction, hydraulic brake function, mechanical parking brake operation, pad replacement, and installation of a new combined fixed caliper. For other Linde training documents on earlier or larger models, check out the Linde E 14-20 335-02 Service Training Manual and Linde H100-600, H120-1200, H140-1200, H160-600, H160-1200 2007 Training Manual. There’s also the related Linde E-Stapler E-20/25/30 Service Training for further reference. For general background on manual transmission theory, you can read Manual Transmission or Cylinder Head Mechanics.

Hydraulic Schematics and Brake System Details

The hydraulic circuit diagrams cover three production periods: up to 3/88, 4/88-6/89, and from 7/89. Each has its own Hydraulikschaltplan. If you need pump motor specs (both work hydraulics and steering hydraulics), they’re in the technical data section with voltage and current ratings. The manual also includes battery dimensions and weights (Section 3.7.8) – critical when you’re swapping an old battery tray. Aftermarket manuals rarely include these details because they’d have to buy a new one for each revision. This one is original.

Frequently Asked Questions

Is this manual in English?

No, it’s in German.

Does it cover all E 20, E 25, and E 30 models?

Yes, it covers Type 325, which includes E 20, E 25, and E 30 in both P (pedestrian) and Z (sitting) configurations. The wiring diagrams and adjustment procedures are broken down by production date, so you can match your truck’s build date to the correct schematic.

Does it include torque specifications?

This is a training manual, not a full service manual, so it doesn’t list every fastener torque. However, it does contain the critical adjustment values for the motor controller: drive current, brake current, acceleration time, and the trim potentiometer settings for the U200 board. For component-specific torque specs (like axle bolts or caliper mounting), you would need the corresponding service manual. But the training manual gives you the electrical and hydraulic setup data that often gets left out of aftermarket reprints.

Can I use this for the hydraulic system?

Absolutely. The manual has separate hydraulic circuit diagrams for three production eras, plus pump motor specifications. If you are troubleshooting a weak lift or a faulty steering pump, you can trace the hydraulic path using these schematics. The brake hydraulics are also covered in detail.

Aftermarket manuals are a gamble. This one is a direct scan of Linde’s own training binder, printed in 1993. If you are maintaining an E 20, E 25, or E 30 forklift and you want the actual factory adjustment procedures and wiring diagrams, this is the document to have on the bench. Access the Factory Manual and get back to fixing the truck, not chasing bad information.
