WARNING
Under no circumstances should you operate the engine without the air filter installed on the carburettor. The air
filter prevents dust and debris from entering the engine and damaging it.
if you operate your engine at any time without the
air filter installed, the engine will be quickly damaged and require replacement of the piston and sleeve (liner).
❑
Using your glow plug wrench, verify that the glow plug is installed in the cylinder
head and tight. If it's not already preinstalled, install it, using one copper gasket.
❑
Lift the fuel tank lid and carefully fill the fuel tank until the fuel level is just below
the top of the fuel tank.
WARNING
Use fuel that is appropriate for nitro car engines.
Do not use gasoline/petrol
or diesel fuel! For the break-in period you should use fuel specifically designed for
r/C nitro car engines that contains no more than 20% nitromethane.
An xTM Racing # 3 Hot Heat-Range glow plug is included with your engine. We suggest having a couple of extra glow plugs
handy, because it can be expected that glow plugs will wear out quickly during the engine's break-in process. This glow plug will
suit most users during the break-in process. you may or may not need to change to a different type of glow plug after the break-in
process is complete.
There are a variety of different heat range glow plugs to suit your engine. Typically, use
a hotter glow plug if you're using 15% - 20% nitro fuel or are running in cooler ambient
temperatures. Hotter glow plugs typically improve idle and transition, too. Use a cooler glow plug if you're running 25% - 30% nitro
fuel or are running in higher ambient temperatures.
see tip on page 16 about running 30% nitro FueL.

❑
Prime the engine by first opening the throttle completely and covering the exhaust
opening with your finger, then pull the pull-starter cord several times until you see
fuel just start to enter the carburettor through the fuel line.
IMPORTANT
Do not pull the pull-starter cord all the way out or damage to the
pull-starter will occur. Use a couple of short pulls - about 7 or 8 inches (18-20cm) long.
❑
Remove your finger from the exhaust opening and close the throttle down to the
idle position.
❑
While holding the xT2 firmly with one hand (keep your hand clear of any moving
parts), carefully pull on the pull-starter cord 3 times, using short, quick pulls.
IMPORTANT
If you can't turn the engine over using the pull-starter, don't force
it. The engine is probably flooded.
see the warning and resolution at the top
of the page.
IMPORTANT
We recommend that you place the chassis on a dedicated car stand or similar so that all four wheels are suspended
off the ground. This ensures that your XT2 does not accidentally drive away when starting the engine if the idle setting is too high.
