Engine cranks but does not fire, E11 ignition fault on display

Safety first: Turn OFF the generator, disconnect battery negative, and remove the spark plug cap before working near the flywheel.

• Check spark plug: Remove the spark plug using a plug socket. Inspect for heavy carbon, oil fouling, or cracked insulator. Clean or replace with the exact type specified by Scheppach. Set the gap to the value in the manual.
• Test for spark: Reconnect the plug to the cap, ground the plug body to the engine, and crank the engine while observing the gap. A strong blue spark should be visible. If no spark, proceed.
• Inspect ignition coil and lead: Locate the ignition coil near the flywheel. Check the high‑tension lead for cracks or burns. Ensure the coil mounting bolts are tight and the air gap to the flywheel is within spec (use a non‑magnetic feeler gauge).
• Check crankshaft position sensor: On electronic ignition models, inspect the crank sensor and its wiring harness. Look for damage or loose connectors.
• Replace faulty components: If there is still no spark, replace the ignition coil assembly and retest. If E11 persists, the control module may be at fault.
