Out on a job, the Bobcat A220 is the loader you use when you need skid-steer agility with the option of all-wheel steer so you're not tearing up turf or asphalt. The people who reach for this service manual are the ones actually turning wrenches in the yard or shop when the machine is down and time is burning. They want the right teardown steps, test ports, and specs so they only pull it apart once. This manual is aimed at that kind of work, not basic operation.
What this manual helps you do
- Diagnose drive issues by checking hydrostatic charge pressures and wheel motor case drain correctly
- Trace and repair electrical problems using readable wiring schematics and connector callouts
- Follow step-by-step removal and installation for major components like pumps, drive motors, and cylinders
- Rebuild and adjust brake, steering, and loader linkage systems so the A220 tracks straight and lifts clean
- Verify engine-related repairs with proper test procedures for fuel, cooling, and basic electronic controls
Who this is for
This is for a small contractor, owner-operator, rental fleet, or shop mechanic working on a Bobcat A220 in the serial range 519611001 through 519699999. If you only need to learn controls, daily checks, and safety, you want the operator's handbook instead, not this service manual.
FAQ
Q: Is this a searchable PDF, and are the wiring diagrams readable?
A: These manuals are usually supplied as searchable PDFs with zoomable schematics that are clear enough on a laptop or tablet in the truck.
Q: How do I know if it covers my exact machine?
A: If your A220 serial number falls between 519611001 and 519699999, this is the correct manual for your machine variant.
Q: Is this the right document if I'm doing my own repairs?
A: Yes, if you're doing real repairs or diagnostics beyond fluid changes, this is the workshop-level manual you want.
Bottom line, if you own or service a Bobcat A220 in that serial range and you're doing your own repairs, this is the right manual. If you just need operating tips, skip it.
