Case 1021G, 1121G Touchscreen Wheel Loader Operators Manual (91762294) (July 2022)

These loaders usually live in gravel pits, feed yards, quarries, snow work, and muddy job sites where the touchscreen gets dusty and gloves stay on. This operators manual helps you actually run the machine right: how the touchscreen ties into the hydraulics, how it behaves when you’re pushing into a pile, backing on a slope, or tracking through ruts. Say you’re loading trucks on a wet morning—this will walk you through how to set the work mode, adjust response, and trace what’s going on when the bucket keeps digging in too fast.

Applications & Use Cases

• Dial in controls so you can check and adjust response on the touchscreen before a shift instead of guessing while you’re already in the pile.
• Verify daily checks—fluids, lights, alarms—so you don’t miss a step and can inspect the machine the same way every morning.
• Isolate weird behavior when a function’s slow or jumpy by using the screen menus to test settings before you call a tech.
• Route and align attachments by learning how the loader’s modes change lift/tilt feel when you swap buckets, forks, or plows.
• Bleed off pressure safely and avoid yanking hoses under load because you’ll know where to look on-screen and on the chassis.

FAQ

Q: Is this manual searchable, or am I stuck scrolling like crazy on my phone?

A: It’s typically a searchable PDF, so you can jump to sections by keyword, which is handy in the cab.

Q: Can I print just a few pages to keep in the machine?

A: You can usually print selected sections, so most folks print the safety, daily checks, and touchscreen basics for jobsite use.

Safety Note

Always verify hydraulic pressure is released and the attachment is grounded before you inspect or disconnect any hoses.
