Tadano GR-300EX-1 Rough Terrain Crane Service Manual

The GR-300EX-1 is a single-cab rough terrain crane with a telescopic boom and outriggers, built to work on uneven ground where a truck crane can't get in. When one comes into the shop with a hydraulic fault, a swing problem or a brake complaint, the technician needs workshop procedures, not guesswork. That's when you reach for the service manual.

What this manual helps you do

Trace faults through the hydraulic power generating system, outrigger system and swing system.
Adjust the boom elevating, boom telescoping and winch systems using the data, adjusting and checks section.
Check the safety system and control system when a function acts up or shuts down.
Rebuild or replace components in the steering, brake and suspension systems.
Follow the system diagrams to track a circuit before you cut into it.

Who this is for

You're a crane service technician, a rental fleet mechanic or an independent repair shop doing the work in-house. It also suits a dealer technician who needs a procedure at the bench, or anyone who just took in a used GR-300EX-1 with no paperwork.

FAQ

Q: How does it fit the job I'm doing?

A: It's laid out by system, from safety and foreword through hydraulics, outriggers, swing, boom, winch, steering, brakes and suspension, then data and diagrams. Open the section for the system you're working on and follow the procedure.

Keep the full set on your shop computer or tablet, search the system you're working on, and have the procedure open before you pull the first component.
