Sany SY155W Excavator Service Manual

A wheeled hydraulic excavator like the SY155W digs, loads and moves material on job sites where tracks would tear up the surface or slow down travel between locations. When one goes down, the person under it is usually a fleet mechanic or shop technician who needs the repair procedure, the test values and the fault meanings in one place. That's what a service manual is for.

What this manual helps you do

• Trace hydraulic and electrical circuits using the hydraulic and electrical diagrams.
• Diagnose faults by working through the trouble diagnosis section.
• Check machine condition against the table of standard values.
• Adjust and verify settings by following the testing and adjustment procedures.
• Rebuild or replace components using the disassembling and assembling steps.

Who this is for

A rental fleet mechanic who repairs machines in-house once warranty is over. Also an independent repair shop or plant maintenance technician who picked up a wheeled excavator with no paperwork and needs a workshop reference.
