Maxford USA Certified Gas Engine Policy
All our gasoline engines are “Quality Checked” (QC’ed) at the CRRC factory before shipment to us, and QC’ed again at the Maxford USA warehouse before being shipped to you. The QC process includes mounting the engine in a test stand and successfully starting and running the engine before it is finally packaged for shipment.
Our gas engines are sold with a Limited Warranty which extends for 1 year from the date of purchase by the original consumer purchaser. Before you start the engine for the first time, to ensure proper care for your engine and to help keep it running reliably, fully read the “engine break-in” and related instructions packaged with the engine.
To maximize your well-being and enjoyment, please read and carefully follow each “Warning” and “For safe operation …” instruction in the CRRC engine’s instruction manual and observe the “Disclaimer” of liability and related safety notices. Furthermore, we offer and emphasize the following warnings and reminders:
CONSUMER’S PRE-STARTUP CHECKLIST FOR CRRC 26CC & 50CC ENGINES:
1. Make sure the spark plug is tightly mounted in the cylinder head and that the high-voltage module’s spark-plug connector is fully seated over the spark plug.
2. The ignition module must be shock-mounted and positioned so that it receives adequate cooling air.
3. Ensure the battery you connect to the ignition module has a capacity of at least 1,000 milliampere-hours, the battery is fully charged and that its terminal voltage measures between 4.8 volts and 6 volts DC.
4. You are responsible to supply and install a mechanical “kill switch” that is easily and safely accessible to disconnect the ignition module from the ignition module’s battery while your airplane is on the ground.
5. You are also responsible to supply and install a radio-operated “kill switch” to disconnect the ignition module from the ignition module’s battery while your airplane is airborne.
6. Use only balanced propellers; NEVER use a propeller that has a nick, dent or other damage.
7. Frequently check to ensure the engine is securely attached to your airplane, and check and re-tighten the prop. shaft, propeller and spinner as necessary.
8. Use a gasoline/oil mixture of between 20 and 25 to 1 during at least the first 15 hours of operation, and carefully follow ALL of your CRRC engine’s “break-in” instructions and precautions. 9. Since your new CRRC engine has been successfully test-run, be careful to note the position of each “out of the box” adjustment, and do NOT attempt readjusting any setting before ensuring you can return the engine to its original factory settings.
10. Do not void the warranty by attempting to modify the engine or attempting to repair a suspected problem.
CONSUMER’S TROUBLESHOOTING GUIDE FOR IN-WARRANTY CRRC 26CC & 50CC ENGINES:
1. If the engine misfires and/or runs erratically, check that the ignition module battery has a terminal voltage of between 4.8 volts and 6 volts DC.
2. The steps outlined in the instruction manual’s “troubleshooting” section are provided as a brief guide for performing non-warranty services. If your engine is still within the terms of Maxford USA’s Limited Warranty for Gas Engines you must obtain prior authorization from a Maxford USA service technician before attempting any in-depth troubleshoot procedures (such as readjustments to the carburetor, carburetor cleaning, and/or ignition timing readjustment).
