What oil goes in the exciter shaft tube, how the electronic immobilizer behaves at start-up, which control sets the crabwalk: the 140-page Bomag BW 174 AP-4 operator manual PDF, factory document 008 064 01 for this tandem vibratory roller, settles those questions the way no forum thread can. Nearly half the book is maintenance, with fuel and lubricant tables covering everything from the sprinkler system to the travel gears, and interval charts running from daily level checks out to coolant changes. Operating chapters walk you through seat rotation and travel direction confirmation, vibration switching, the edge cutter, and mounting the precision spreader. Blow the combustion air filter clean at no more than 2.1 bar, and call your battery fully charged only at 12.6 volts across the poles. Guess wrong on the exciter oil and the drum pays for it. Bookmarked and text-searchable, this PDF goes wherever the roller does.
