Need the factory reference for your Schaeff TC08 crawler excavator? All 352 pages of this service manual PDF (OEM #MMT01ENMA00100) target one machine: engine teardown and rebuild, full undercarriage overhaul, swing bearing and controls procedures, hydraulic pressure adjustment, and a dedicated troubleshooting section. You get complete hydraulic circuit schematics with fluid routing and circuit operation detail, wiring diagrams for the machine's electrical systems, and page after page of tightening torque tables from the control valve to the travel motor. Torque the system relief valve adjustment screw (M14) to 19.6 N·m; replace the hydraulic motor shaft oil seal when wear hits 0.025 mm. Every hour your TC08 sits idle costs money. Bookmarked by section: pull it up on your phone, find the spec, and fix the machine.

Schaeff TC08 Common Problems This Manual Covers
Schaeff TC08 engine won't start or turns over slowly in cold weather
Check fuel: the tank requires No. 2-D diesel; wrong grade causes hard cold-weather starts (page 315). Verify cold-engine valve clearance — intake and exhaust should both measure 0.2 mm (page 30). If cranking but not firing, test compression; minimum acceptable is 2.9 MPa at 300 rpm. Trace the start circuit and battery charging connections in the electrical section at page 235.
Manual Section: Engine Troubleshooting (General)Boom and bucket move slowly or stall short of full lift capacity p. 135
Verify hydraulic oil level in the 5.7 L tank and confirm the fluid is ISO VG46 (page 315). Check system relief pressure; the spec is 18.1 MPa for P1/P2 (page 27). If below spec, adjust the relief valve and re-torque the M14 adjustment screw to 19.6 N·m (page 135). Inspect control valve spool operation for internal leaks per the hydraulic equipment section at page 141.
Manual Section: Hydraulic System Pressure AdjustmentUpperstructure drifts and won't hold working position after swing lever release p. 319
Inspect the swing motor for internal leakage and verify swing brake valve pressure holds at 6.9 MPa (page 27).
Frequently Asked Questions
How to reset the hydraulic system on Schaeff TC08 mini excavator?
To reset the hydraulic system, perform an air release procedure. Run the engine at medium speed and activate each hydraulic circuit for about 10 to 15 minutes. For hydraulic cylinders, set the engine speed to low idling, then slowly extend and retract the cylinder 4 to 5 times up to 50 to 100 mm from each stroke end, followed by fully extending and retracting 3 or 4 times.
What are the torque specs for the rubber track bolts on Schaeff TC08?
For the track roller, the tightening torque for M12 x 25 bolts is 78.5 to 98.1 N·m, and Three Bond 1324 or its equivalent adhesive should be applied. For the sprocket, the tightening torque for Hexagon socket bolt M10 x 25 is 44.1 to 58.9 N·m, also with Three Bond 1324 or its equivalent adhesive.
What is the correct dig force specification for the Schaeff TC08 bucket?
The correct maximum digging force specification for the Schaeff TC08 bucket is 10.5 kN. This is listed under the work performance specifications for the machine.
How to reset hydraulic pressure on Schaeff TC08
To adjust the hydraulic pressure for the system relief valve, retract the arm or bucket cylinder to its stroke end and hold the control lever in that position, then read the gauge. If the measured value is not the set pressure (18.1 MPa for system relief valve), loosen the M14 nut and turn the adjust screw to achieve the specified pressure.
