STORAGE FOR A LONG PERIOD AND USE THEREAFTER
Always follow instructions below after your engine has been stored over a long period.
When your engine has not been used for more than 4 weeks
1.
Ideally remove fuel from the fuel tank and replace with fresh fuel for best
performance and starting reliability. Older fuel looses a % of volatiles through
evaporation even inside the fuel tank (which is marginally porous) and starting the
engine becomes more difficult. The exhaust becomes oilier and you may also notice
a drop in engine power. Using old fuel will not harm your engine up to about 2
months at which point the properties in the two stroke oil will deteriorate and you
will risk damaging the engine through poor lubrication.
2.
You may find that the starter battery charge is low, it is important to keep this
topped up regularly with the charger supplied. If the battery is low then start
charging at least 12 hours before you intend to fly to avoid disappointment as the
engine requires a well charged battery to start reliably. The charger can be left
connected and charging for up to 4 days with no adverse affect on battery or
charger.
When the engine is not used for more than 3 months
1.
In order to prevent the piston rings and bearings from rusting, remove the ignition
plug and apply a small amount of special purpose oil through the plug hole. After
pulling the starter handle several times lightly for lubrication, install the ignition plug
back into the engine.
2.
After cleaning and drying the various portions of the engine, wrap the engine in a
vinyl bag.
3.
Store the engine in a dry and well ventilated location away from direct exposure to
sunlight.
4.
Parajet supplies Briggs and Stratton ‘Fuel Fit’ it is recommended that you use this
additive in your fuel to help clean out the system after a long period of no use. It
helps to remove residue in the carburetor and fuel system.
