The OM 457 LA, OM 460 LA, OM 501 LA, OM 502 LA and OM 904-926 LA are the diesel engines that power cranes and other heavy machines. If a used crane came in without the book in the cab, this is the operator manual you'd want on file before anyone turns the key.
What this manual helps you do
- Start, run and shut down the engine using the operating instructions for driving mode and working mode.
- Check the engine daily and follow the maintenance schedule at the intervals it sets out.
- Read the warning lights and use the fault table when something trips on site.
- Learn the safety rules before a new or relief operator takes over.
- Look up fuels, lubricants and coolants, plus the technical data, without hunting through the cab.
Who this is for
A buyer of a used crane, or an owner-operator, who needs the engine's operating and care rules on hand. It also suits anyone handing a machine to a relief operator and wanting the daily checks written down.
