The Bomag BM 1000/30-2, BM 1200/30-2, BM 1300/30-2 service manual PDF (OEM 008 917 61) tears into all six variants of this cold milling machine family, PB versions included, across 826 pages of factory repair data. Electric circuit diagrams and the full hydraulic diagram close the book, and the electrics chapter walks you through every sensor and operating condition, from rope sensors for height control to the multi-function display. Component overhaul procedures for the steering, travel and conveyor belt pumps, the travel motor, travel gear and Planox clutch run from page 345 to page 746, roughly half the book, with each rebuild ending in specification tolerance lists. Blow out the main air filter element at no more than 5 bar, and retire the milling drum V-belt pulley once it wears past 15.24 mm. A guessed charge pressure kills an axial piston pump quietly. Bookmarked and carrying a text layer, the file lives on whatever laptop or tablet follows the machine, so your specs travel wherever the milling drum does.

Bomag BM 1000/30-2, 1200/30-2, 1300/30-2 Common Problems This Manual Covers
Bomag BM 1000/30-2 milling drum stalls under load, V-belts squeal and smell burnt
Check the milling drum V-belt tension: the belt set should compress approximately 100 mm under 50 N of force, per the spec on page 224. Measure the pulley grooves while you are in there; replace pulleys worn from 14.24 mm to 15.24 mm groove width, then retension or renew the belts as a matched set.
Manual Section: Milling Drive, Repair p. 224Engine cranks slowly or the starter just clicks on cold morning startups before the shift
Test battery voltage under load first, then inspect the battery ground and cylinder head ground cables for corrosion. Clean and retorque the starter terminal B connection to 9.8 to 11.0 Nm, listed on page 178. If the starter still drags or the return mechanism jams, work through the starter troubleshooting table before buying a new one.
Manual Section: Starter Troubleshooting p. 178Engine down on power with black exhaust smoke when milling at full depth
Remove the main air filter element and hold it against a light. Clean from the inside out with compressed air limited to 5 bar maximum, per page 202, and replace the element if the paper is torn or oily. Check the fuel filters too; a starved engine smokes the same way under drum load.
Manual Section: Engine p. 202Conveyor belt slips and spills millings under the machine instead of loading the truck
Check belt tension with the engine shut down. Press each belt midspan: the gathering belt should give 50 mm under 100 to 150 N, the loading belt 70 mm under the same force, as set on page 268. Tighten both sides evenly, then watch that the belt tracks centered before loading resumes.
Manual Section: Conveyor Belt, Repair p. 268Travel gear growls in one crawler track and leaves oil spots after parking
Drain the track drive gear oil into a clean pan and look for metal glitter, which points to bearing or planetary wear inside the travel gear. Change the gear oil every 1000 hours as listed on page 617, repair the leak at the shaft or cover seals, and refill to the level plug before crawling back onto the mat.
Manual Section: Travel Gear p. 617Water spray dead at the drum, cutting tools running hot and wearing fast
Verify the 1250 liter water tank is full and the suction valve open, then pull and clean the water filter screen. Test the flow control valve, solenoid valve and pressure switch in the sprinkling system, covered from page 669, and clear each nozzle body. Do not cut another pass dry; hot picks die fast.
Manual Section: Sprinkling Pump p. 669Frequently Asked Questions
What is the procedure for resetting the error codes on the BM 1000/30-2?
The manual states that saved error codes are automatically erased after 100 operating hours. For active diagnostic codes, they can be invoked and erased using a diagnostics service tool. Certain codes can only be erased from the log of the control unit by using a password. p. 194

Cutting tools with missing hard metal must be replaced immediately to prevent severe damage to the milling drum or tool holders. When replacing, ensure the new cutting tool is knocked into the holder until it bottoms and check that it can rotate freely. p. 232
What is the engine oil capacity for the BM 1000/30-2?
The manual doesn't spell out the engine oil capacity in liters; it has you check the level with the dipstick and top up to the 'MAX' mark shown in Fig. 13 on page 197. p. 197
What is the correct coolant mixing ratio for the Bomag BM 1000/30-2 engine?
The coolant should always be a mixture of anti-freeze agent and clean, dehardened water at a 1:1 mixing ratio, per section 3.1 on page 38. p. 38
