All 902 pages of this Same Diamond 210, 235, 265 repair manual PDF cover one tractor family, front axle to rear PTO. You get full wiring harness diagrams with connector layouts and fuse maps, hydraulic schematics for the load sensing variable displacement pump, and a heavy section of alarm and error code analysis for the engine, transmission, and HPSA control units. Fighting a CANBUS fault? Inside are complete walkthroughs for the EDS and Serdia Level III diagnostic software, from ECU selection to error memory. Torque the M12x1.75 fasteners to 66.5-73.5 Nm, fill the cooling system with 34L, and top the hydraulic reservoir off at 20L. No more chasing electrical gremlins with a multimeter and a prayer. Bookmarked so you can jump straight to any section, and it opens on any device; take your phone out to the tractor and get wrenching.

Same DIAMOND 210, DIAMOND 235, DIAMOND 265 Common Problems This Manual Covers
Same Diamond 265 hydraulic trailer brakes weak, trailer won't stop under load, pedal feels normal
Test pressure at trailer brake port B with a gauge. You need 12.5 bar constant minimum and no more than 135 bar peak, both listed on page 51. Confirm the master cylinder circuit holds its 120 bar operating pressure per page 48. Bleed the circuit and retest before condemning the trailer brake valve.
Manual Section: Braking System p. 51Air compressor runs constantly, system pressure builds slowly, trailer air brakes feel sluggish
Check compressor output with a test gauge on the delivery line. Maximum system pressure is 10 bar, page 56, and the pressure limiting valve should cut out at 7.8 bar on Italian-market units, page 57. Drain the air tank, inspect for oil carryover, and test the governor before replacing the compressor.
Manual Section: Braking System p. 56Front axle suspension rides harsh, bounces over rough ground, won't hold set height
Check nitrogen precharge in the suspension accumulators. ASP1 and ASP2 should read 65 bar and ZSP1 should read 140 bar, listed on page 63. Recharge or replace any accumulator that has lost its charge, then verify the relief valve holds 250 bar. Cycle the suspension control valve through full travel and recheck ride height.
Manual Section: Hydraulic Front Axle Suspension p. 63Transmission control unit alarm codes on instrument panel, gearbox drops into limp mode
Read the stored codes with the EDS diagnosis software and match them against the alarm tables starting. Before chasing wiring, verify hydraulic supply: the transmission oil cooler relief valve opens at 3.8 bar, shown on the schematic on page 31. Inspect the control unit connectors for corrosion and repin damaged terminals.
Manual Section: Transmission Electronic System Alarms p. 159Cab air conditioning blows warm air, compressor short cycles, vents barely cool at idle
Recover the refrigerant, pull a vacuum, and weigh in exactly 1900 g of refrigerant per page 538. Add 210 cm³ of compressor oil only on a first charge. If the system was opened, follow the full discharging and flushing procedure before recharging, then leak-test every fitting before releasing the tractor.
Manual Section: Air Conditioning System Maintenance p. 538Frequently Asked Questions
What are the torque specifications for standard M12x1.75 bolts of class 8.8?
For standard M12x1.75 bolts of class 8.8, the tightening torque is 66.5–73.5 Nm (49.0–54.2 lb.ft.). p. 14
How do I clear passive alarms on the HPSA control unit?
To clear passive alarms, access the '4. ALARM MENU' on the HPSA control unit tester, select '4.5 CLEAR PASSIVE ALARMS', and choose the specific system (HPSA, engine, transmission, or armrest) to clear. The message 'ALARM ARE BEEN ERASED' will confirm the action. p. 372
What is the procedure for bleeding the hydraulic brake system?
To bleed the brakes, attach a transparent bleed tube 'A' to the bleed screw (1) of the cylinder (2). Depress the brake pedal fully, slowly open the bleed screw to allow fluid and air to escape, then tighten the screw while holding the pedal depressed. Repeat until the fluid is free of air bubbles. p. 577
What is the required coolant capacity for the engine cooling system?
The engine cooling system requires approximately 34 liters (9 US gallons) of coolant. p. 525
What is the correct tightening torque for the towing hitch support bolts?
The support bolts for the towing hitch must be tightened to 400 Nm (295 lb.ft.). p. 724
