Removing valves
Information
Secure the cylinder head on a level surface, which allows easy access to the valves from underneath.
No valves should be hidden by the surface under the cylinder head.
The cylinder head fastening must not tip over when tools are used.
1. The spark plugs must be removed and the valve lock screwed in before the valves are removed. The valve lock prevents the valves from being
opened while being pressed down.
Alternatively, a rubber plate placed underneath helps if the cylinder head surface is smooth -2-.
