Following a simple maintenance schedule will ensure that your Mammoth RTR Nitro Monster Truck, engine and radio system operate
in top condition every time you use them. It is strongly suggested.

●

Check the foam air filter element for dirt blockage. If the foam

is dirty, remove it from the filter housing and wash it in liquid soap
and warm water. Dry the foam element with a paper towel,
reinstall it and "wet" it with after-run oil.

●

Check the chassis for any loose screws, especially the engine,

tuned pipe and outdrive cup mounting screws. Tighten them if
necessary.

●

Check the steering linkage and the throttle/brake linkage for

any signs of wear or misalignment. Tighten and/or readjust them
if necessary.

●

Once in a while, remove the wheels and clean the wheel bearings

using a bearing cleaner. This will remove any dust and grit that
may, over time, damage the bearings. After cleaning the
bearings, re-oil them using a good quality bearing oil. Never run
the bearings dry or damage to the bearings will result.

●

Check the fuel system, including the fuel tank and fuel lines,

for any signs of cracking or looseness. Replace any fuel line you
suspect may be damaged.

●

Periodically check the condition of the transmitter and receiver

batteries. If you think they might be low, replace them with a
fresh set.

●

Included in your kit is a plastic sprue that includes some plastic

replacement parts. Included are fuel line clips, throttle linkage
mounts and other small accessories.

●

After a period of time the chassis will accumulate a lot of dirt

and debris, especially around the engine area. This build-up
should be cleaned off using a high-powered spray cleaner like
Emerald Nitro Car Cleaner. Some nitro car cleaners will damage
anodized and/or plated parts. Test on an inconspicuous
area first.

●

After cleaning the chassis and engine with Nitro Car Cleaner

you should oil the moving parts of the chassis. Do not oil the
clutch bell, spur gears or the brake discs.

●

Always use new fuel and keep the cap on the fuel tightly closed.

As fuel ages it absorbs water, which degrades the fuels performance
and will cause erratic engine operation.

●

After you have finished using the engine for the day, remove

the glow plug and squirt several drops of a high-quality after-run
oil into the cylinder. Reinstall the glow plug and crank the engine
over a couple of times (without the glow starter attached) to
distribute the oil. This will prevent corrosion inside the engine.

●

Never leave unused fuel in the fuel tank for more than a couple

of days. The nitromethane and methanol in the fuel will
evaporate, leaving the oil behind. This will eventually turn into a
thick sludge that will require replacement of the fuel tank to fix.
