The first 50 operating hours — break-in service
For a new or overhauled engine, the first oil change after 50 hours is especially important. During break-in, small metal particles are released that you want out of the engine as soon as possible. After the first 50 hours, replace: engine oil, transmission oil, power steering oil and front axle oil. Also have the hydraulic filters (A and B) and the engine oil filter replaced.
Engine oil
Type: Iseki Diesel Engine Oil (or equivalent diesel engine oil, minimum CC class). A 15W-40 is suitable for most conditions.
Capacity: 3.1 liters
Interval: First time after 50 hours, then every 100 operating hours.
Checking: Pull out the dipstick, wipe it clean, reinsert it (without screwing it in) and pull it out again. The oil level should be between the upper and lower marks.
Replacing: Loosen the drain plug (bottom of engine block) and let the oil run into a collection tray. Screw the plug back in, fill with 3.1 liters of fresh oil through the filler opening on top of the engine.
Transmission oil
Type: Iseki Multi-Deluxe Oil (#80) or equivalent gear oil GL-4 or higher.
Capacity: 10.0 liters (K and H version: 11.0 liters)
Interval: First time after 50 hours, then every 300 hours.
Note: the transmission oil and hydraulic oil share the same system. After replacing, you must always bleed the system: loosen the drain plug, start the engine for 5 seconds, stop, tighten, check the level and top up if necessary.
Front axle oil
Type: Iseki Multi-Deluxe Oil (#80)
Capacity: TF15/TF17: 4.0 liters (H version: 4.5 l) | TF19: 4.2 liters (H version: 4.7 l)
Interval: Check every 100 hours, replace every 600 hours.
Power steering oil
Type: Iseki hydraulic oil (ISO 32)
Capacity: 1.1 liters
Interval: First time 50 hours, then every 300 hours.
After replacing: start the engine and turn the steering wheel fully back and forth 5× to remove air from the system.
Coolant
Type: Clean water with antifreeze (LLC) — for example Mobil Long Life Coolant or Shell antifreeze.
Capacity: 5.0 liters
Interval: Replace once a year. Check level daily.
