The Bobcat S100 is one of the most practical compact skid steer loaders for contractors who need full-size skid-steer functionality in restricted work areas. With a machine width of approximately 42.1 in (1,069 mm), a rated operating capacity of about 1,000 lb (454 kg) and an operating weight near 4,610 lb (2,091 kg), the S100 is widely used for landscaping, pallet handling, livestock operations, municipal maintenance and indoor construction projects where maneuverability is essential. This OEM factory repair and service manual, Publication No. 6987401enUS, is specifically written for the listed serial number ranges, ensuring that the procedures, specifications and illustrations match the covered production machines.
This is a dealer-level workshop manual designed for technicians who need accurate hydrostatic drive diagnostics, hydraulic pressure testing, chaincase servicing, electrical troubleshooting and complete component overhaul procedures rather than generic maintenance information commonly found online.
