Trench backfill won't compact itself, and a BPR 70/70 D that quits mid-lift leaves the whole crew standing. The Bomag BPR 70/70 D operator manual PDF (OEM 008 067 61) puts all 76 factory pages of operating and maintenance instruction for this reversible vibrating plate in your hands. A full maintenance table walks the schedule from daily engine oil and air filter checks out to the two-year hydraulic oil change, while troubleshooting covers jump-wire starting, engine problems and the Economizer. Indicator descriptions, loading and transport steps, and the safety regulations fill out the operating side. Change the exciter housing oil, roughly 0.6 liters, at least every 500 operating hours, and set V-belt deflection between 10 and 30 mm before blaming the drive. Guess a drain plug torque and you strip the case; this book prints 20 Nm. Bookmarked and text-searchable, the PDF goes wherever the plate does.

Bomag BPR 70/70 D Common Problems This Manual Covers
Bomag BPR 70/70 D engine won't start or shuts down shortly after starting
Check engine oil level first; the low oil level safety device shuts the engine down and blocks restart until it is topped up. Fill to the mark, engine oil capacity is 1.9 l. Verify fuel in the 10.0 l tank, then check the air filter service indicator and work through the engine problem charts on page 70.
Manual Section: Engine Problems p. 70Weak vibration and poor compaction, plate needs extra passes to reach density
Check V-belt tension first; belt compression should measure 10 to 30 mm (0.4 to 1.2 in) under thumb pressure, per the procedure on page 59. Inspect the exciter housing oil level next; the housing holds approx. 0.6 l, and the schedule calls for an oil change at least every 500 operating hours.
Manual Section: Maintenance p. 59Engine loses power or overheats after a few hours in dusty conditions
Check the air filter service indicator and clean or replace the element whenever it trips; dust loads it fast on dry lifts. Clean the cooling fins and air intake openings so the engine can shed heat between passes. Verify oil condition too; the schedule on page 39 sets a 250 operating hour engine oil change interval.
Manual Section: Maintenance p. 43Plate won't reverse or travel is jerky and sluggish in one direction
Check the hydraulic oil level before starting and top up if low; the travel and reversing functions run on the hydraulic circuit and starve first. Inspect hoses and steering rod fittings for leaks and wipe down to spot fresh oil. If the filter connecting flange has been disturbed, verify it is tight at 13 Nm on page 62.
Manual Section: Maintenance p. 62Economizer status LEDs flash a code and compaction readout stops working mid pass
Check the status LED code against the Economizer diagnostic table in the troubleshooting section beginning on page 67. Verify the display connector is seated and free of dirt before swapping parts. If vibration itself feels weak, measure V-belt compression; anything outside 10 to 30 mm (0.4 to 1.2 in) means the belt needs adjusting.
Manual Section: Trouble Shooting Economizer p. 67Frequently Asked Questions
What causes the BOMAG BPR 70/70 D to lose vibration?
Loss of vibration can be caused by a slipping V-belt or an incorrectly installed V-belt. Additionally, if the Economizer status LED is flashing, it may indicate that the vibration frequency is too low or the engine speed is too low. p. 72
What are the replacement specifications for the air filter?
The air filter must be changed after several cleanings, but at the latest after one year. When cleaning, blow it out from inside to outside with dry compressed air at a maximum pressure of 5 bar (72 psi). p. 63
What are the replacement specifications for the fuel filter?
The fuel filter is replaced by pulling it out of the top and bottom hoses. When installing a new filter, ensure you observe the correct flow direction as indicated on the component. p. 56
What is the nominal valve clearance for the engine?
The nominal valve clearance for the intake valve is 0.10 mm (0.004 inch), and for the exhaust valve, it is 0.20 mm (0.008 inch). These should be checked and adjusted only when the engine is cold. p. 53
What is the required tightening torque for the engine oil drain plug?
When changing the engine oil, the oil drain plug must be cleaned and screwed back in with a tightening torque of 20 Nm (14.8 ft.lbs). p. 55
