FUEL:
Use fresh 2-stroke model car fuel only, never use regular gasoline or airplane fuel! We recommend using our line of
LRP high-qual ty fuels. For the LRP Z.18S Pro Pullstart engine we recommend fuel with 16% n tro. A higher n tro
content decreases your engine’s lifetime. Do never exceed 30%.
AIRFILTER:
A good airfilter is very important for the life of your engine. Never run w thout an airfilter, as quick and permanent
damage will result! Don’t forget to impregnate the airfilter w th a su table oil before usage. Carefully clean the airfilter
at least after every fifth tank. Replace the airfilter every 3l tres (~1 gallon) of usage.
GLOW-PLUG:
Use only standard style glow-plugs for this engine, we recommend using our line of LRP high-quality glow-plugs
(availabe as R3 to R6). Check them frequently and never run with worn-out or old glow-plugs since they could damage
your engine. They turn dull when your engine was too lean and should be replaced, they should stay bright like
chrome.
Whenever you have trouble with the engine stalling for no reason, replace the glow-plug first!
EXHAUST SYSTEM:
Never run w thout a pipe since this will cause excessive overheating and may damage your engine. A proper pipe lets
2-stroke engines run properly and fast. We recommend using our line of LRP high-qual ty pipes and headers.
PULL STARTER:
Always pull the handle straight and don’t let the cord rub on anything. Do not fully extent the cord as this may abuse
and damage the pull starter (using about 2/3 of the complete length of the cord is enough to start your engine).
Don’t let fuel get in contact with the pull starter as this may weaken t. The Pull Starter is designed to start the engine
running in a counterclockwise rotat on.
Forcing the flywheel clockwise will cause sever damage to the pull
starter.
