What This Manual Gives You

This Skyjack SJ800 Series Maintenance and Parts Manual is far more than a parts catalog. It puts the complete maintenance and repair workflow in your hands: diagnose a fault from the detailed troubleshooting tables, confirm the correct pressure setting or torque value from the service data, identify the exact part from exploded-view diagrams, and cross-reference relays, solenoids, and electrical components against the relay function chart and electrical schematics. The hydraulic schematic shows every valve, pump, cylinder, and line in the system, and the electrical schematics break down the full harness routing for each engine variant.

Multiple engine platforms are documented side by side — Nissan A15 dual fuel, Kubota D902 / D1105 diesel, Kubota DF972 dual fuel, and GM 1.6 dual fuel — each with its own wiring diagrams, diagnostic flash code procedures, and sensor resistance charts. Serial number breakdown tables tell you which diagram or part number applies to your specific machine, whether early or late production.

Who This Manual Is For

Shop technicians performing scheduled maintenance or troubleshooting an inoperative function; fleet maintenance managers keeping a mixed fleet of SJ800 rough terrain scissors in service; and knowledgeable owners who handle their own brake adjustments, hydraulic checks, and electrical diagnostics. Anyone who needs to look up a torque specification, trace a circuit, or find the correct replacement part for models 7127, 7135, 8243, 8850, 8831, 8841, or 9250 will find the answer in these pages.
