Emphasizes the engine is not a toy and DLE is not responsible for safety issues.
Engine must be operated in a properly ventilated area for safety.
Ensure components are secure and tight; recommends screw sealant for installation.
Warns about vibration during break-in and potential damage if not properly dampened.
Keep foreign objects away from the propeller to prevent them from being sucked in.
Avoid starting the engine on loose gravel or sand to prevent debris ingestion.
Do not attempt to stop the engine by throwing objects into the propeller's path.
Use gasoline-approved rubber fuel lines and keep them away from cylinder heat.
Never touch the engine immediately after running as it will be hot.
Remove all fuel from the tank and lines before transporting the model.
Use high-quality 2-stroke oil, recommending petroleum-based for break-in.
Install electronic radio devices away from the engine to prevent interference.
Drain fuel tank and carburetor for long-term storage to prevent damage.
Use a filter designed for gasoline engines to prevent fine particles from entering.
Keep gasoline away from open flames, heat, or spark sources due to flammability.
Do not smoke near the engine or fuel tank due to fire risk.
Engine is designed for model aircraft use only; not for other purposes.
Always install an ignition system on/off switch on the aircraft.
Running lean can cause overheating and spark plug damage; adjust high-speed needle carefully.
Use fresh 87-93 octane gasoline with a 30:1 fuel/oil mixture for best performance.
Excessive idling can lead to carbonized spark plugs.
Keep the engine clean for proper heat dissipation and ensure adequate cooling/ventilation.
Never rotate the propeller with ignition ON and plug removed to prevent ignition system damage.
Recommended installation of kill switch between on/off switch and ignition for safety.
Check all screws and bolts for tightness and inspect for cracks or missing parts before proceeding.
Connect the ignition module pick-up lead to the engine's pick-up sensor wire using securing clips.
Connect the ignition on/off switch lead to the electronic ignition module's red connector.
Connect ignition module battery; optional kill switch installation is detailed with LED indication.
Install the ignition on/off switch in an easily accessible location on the aircraft.
Securely mount the ignition module and battery using foam and Velcro straps for vibration dampening.
Secure all electrical connections with heat shrink tubing for reliability.
Install remaining silicone wire covers over ignition wires to protect them.
Install spark plugs into cylinders with proper torque (7-8lbs); do not overtighten.
Install the DLE-60 on a minimum 3/8" plywood firewall; reinforce glue joints.
Specifies the engine's overall length from mount back to propeller hub face.
Use the supplied template to accurately drill engine mounting bolt holes in the firewall.
Install blind nuts and use specified screws, lock washers, and standoffs for engine mounting.
Install fuel tank with gasoline-approved components; describe vent line and fill line options.
Install throttle servo at least 12" away, ensure full rotation, and use non-metallic linkage.
Reposition throttle arm for servo linkage alignment; optional throttle return spring removal.
Recommends hand-operated choke pushrod; details servo-operated choke conversion steps.
Connect the ignition module wires to the spark plugs securely.
Install mufflers using threadlocker, ensuring ignition wires do not contact them.
Cut necessary holes in the cowl for clearance, cooling, carburetor, and exhaust.
Support the ignition sensor wire close to the pick-up to prevent flight load damage.
Ensure cowl is secure and has 1/8" clearance from spinner back plate; run without cowling initially.
Explains methods for drilling propellers, either with a guide or manually.
Remove cowling and use propeller washer to mark the centering hole on the propeller.
Drill pilot and finishing holes for the propeller using specified drill bit sizes.
Set the engine at the beginning of the compression stroke to note ignition magnet position.
Place the propeller on the crankshaft at the one o'clock position for marking outer holes.
Use a locator tool to accurately mark the position of the propeller's outer mounting holes.
Drill outer holes in the propeller using specified pilot and finishing bits, drilling halfway from each side.
Use hardware and locator to mark the remaining three propeller mounting holes.
Drill the remaining three holes in the propeller to complete the mounting pattern.
Securely mount the propeller to the engine using specified hardware and threadlocker.
Provides a step-by-step guide for safely starting the DLE-60 engine manually.
Details the procedure for starting the DLE-60 engine using an electric starter.
Diagnoses and fixes for engine not firing: low battery, faulty wires, spark plug issues, or flooding.
Diagnoses and fixes for engine cutting out: fuel delivery issues (tank, line, carburetor).
Warning about potential bodily harm from high voltage when checking spark.
Identifies carburetor controls: Choke, Throttle, Idle Adjustment, Low-Speed Needle, High-Speed Needle.
Adjusts idle speed by turning the Idle Adjustment Screw clockwise (increase) or counter-clockwise (decrease).
Adjusts fuel/air mixture at low speeds; default setting is 1.25 turns open.
Adjusts fuel/air mixture at high speeds; default is 1.5 turns open. Use tachometer for best results.
Adjusts ignition timing by loosening sensor screws and sliding the sensor.
Fixes hesitation on acceleration or idle RPM increase by adjusting low-speed needle (too lean).
Fixes unsteady idle by adjusting low-speed needle (too rich).
Fixes engine stopping at full throttle or hesitating by adjusting high-speed needle (too lean).
Fixes failure to reach full RPM or carbon build-up by adjusting high-speed needle (too rich).
Instructions for cleaning the carburetor fuel filter, including removing the filter cover.
Lists optional parts available for purchase, such as tachometers and kill switches.
