●
During the break-in period, it is recommended that the engine be
installed on the aircraft or a test stand with an appropriate shock
absorber. Otherwise it is probable that vibration could rebound
back to the engine and serious damages may occur during the
break-in period.
Break-in should be considered about the fi rst 3-5
gallons you run through the engine.
●
For your safety and the safety of others, please do not stand in
front of or in line with the propeller when the engine is running.
Keep onlookers away from the running engine, especially small
children.
●
Always use a balanced spinner and a balanced propeller. An
unbalanced spinner and propeller combination will cause high
levels of vibration and may cause the propeller shaft to break.
Always use a lightweight spinner on your engine. Lightweight
spinners are considered to be those with a cone wall of 1mm
or less. Heavy spinners could cause the propeller shaft to break.
Securely tighten the spinner and propeller on the engine to prevent
it from being thrown off the engine while running.
●
Never use a propeller that has hit the ground. Even though it may
look good from the outside, it may be cracked on the inside which
may cause it to disintegrate while in use. Do not use a nicked,
cracked or split propeller.
●
Keep foreign objects away from the propeller. Make sure that
nothing can be “sucked in” by the propeller.
●
Never start the engine on loose gravel or sand.
●
Do not attempt to stop the engine by throwing anything into the
path of the propeller.
●
Make sure the fuel line is well-secured to the engine and to the fuel
tank so that it won’t come off in fl ight.
●
Do not use silicone fuel line because it will be dissolved by the fuel.
Use gasoline approved vinyl or neoprene rubber fuel line. Always
secure the fuel line away from the cylinder head. The engine’s heat
can damage the fuel line.
●
Never touch the engine immediately after a run. The engine will
be hot.
●
Before transporting your model, remove all the fuel from the fuel
tank and fuel lines.
●
Always use high-quality oil intended for 2-stroke (2-cycle) engines.
It's a good idea to use a petroleum-based 2-cycle motor oil like
Lawn Boy All Season - Ashless oil for the break-in period.
●
Do not install your throttle servo inside the engine compartment.
Doing so could cause radio interference. Install all electronic radio
devices at least 305mm [12"] away from the engine.
