Frequently Asked Questions

Bonhoeffer engines are developed, tested and certified with petroleum based motor oils as a lubricant. Synthetic oils may be used; however, any motor oil used in our engines must meet all oil requirements as stated in the owner Manual. In addition, recommended oil change intervals must be followed.

See our Carburettor workshop Sheet to learn more about cleaning carburettors. Please be aware that the engine should be serviced by an Bonhoeffer Authorized Dealer unless the owner has proper tools, service data and the necessary technical skills.

Bonhoeffer engines are designed and certified to run on regular unleaded gasoline containing no more than 5% ethanol (E10). Gasoline is allowed, by regulation, to contain a variety of additives. The same regulation limits how much of some additives, such as alcohol, can be included in the fuel and still allow it to be sold as gasoline. If you look in a Bonhoeffer product owner's manual, you will see that a maximum of 5% ethanol is allowed (other oxygenates are also listed). Bonhoeffer engines are designed for good performance and efficient operation using gasoline containing from 0 to 5% ethanol. Always refer to the owner's manual for your Bonhoeffer to get a list of recommended fuel and the current approved additives. For more information, see our Fuel Recommendations Link. Download or print a handout on how to avoid fuel-related problems for your Bonhoeffer general purpose engine.

If you purchased a new piece of equipment and are missing parts or manuals, you need to contact your selling dealer. If you have further questions, you may contact our Customer Relations office at Manuals and Brochures.

If a problem occurs with the spark plug: Check the spark plug HT wire and connect it if necessary. Remove the spark plug cap. Clean any dirt from around the spark plug base, and then remove the spark plug. Grounding the side electrode to the engine, pull the recoil starter to see if sparks jump across the gap. If there is no spark, replace the plug. If there is a spark, reinstall the spark plug and start again. If the air cleaner is clogged, clean or replace the air cleaner. If the carburetor is clogged, clean the carburetor. Check if the valve clearance is correct. If not, readjust the valve clearance to the correct setting by the help of filler gauge. Check if the governor is out of adjustment. If so, readjust the governor. If the problem is not solved, take your engine to an authorised Bonhoeffer dealer.
