Filling the Fuel Tank
Use a fuel dispensing bottle (Traxxas Top Fueler, part #5001)
to put fuel into Nitro Slash's fuel tank. To fill the fuel bottle,
squeeze the air out, insert the dispenser tip into the fuel
can, and release your grip on the bottle. As the bottle
expands, fuel will be drawn into it.
To fill your model, flip up the springloaded cap on the fuel
tank, insert the tip of the fuel bottle, and squeeze
to dispense the fuel. Fill the tank until the fuel
level reaches the base of the filler neck. Close the
fuel tank lid, making sure it closes tightly.
THE AIR FILTER
The TRX 3.3 Racing Engine in this model is equipped with a specially
designed two-stage air filter to deliver maximum filtering efficiency and
performance while protecting your engine from dust and dirt during
extended operating conditions. Use only the supplied filter. You will not
improve engine performance by switching to an aftermarket filter,
and you may risk engine damage due to poor filtration.
The two-stage TRX Racing Filter consists of the following components:
1. A rubber filter base
2. A 3-piece plastic housing
3. A "pre-filter" element
4. A "primary" filter element
You must clean the outer pre-filter after every hour of run time, even if
the filter looks clean.
The primary filter element inside must be cleaned
after 3-4 hours of run time. These intervals include the break-in time.
Clean your air filter after break-in. Dust (which is often too fine to see)
and dirt constantly move through the filter anytime the engine is running.
Even if you can't see dirt on the filter, it is present inside the foam after any
amount of run time. If you exceed the recommended cleaning intervals,
your engine will be damaged. Engine damage or wear due to dirt ingestion
is easy to detect, and one of the top causes of premature engine failure.
Pre-Filter Cleaning Instructions (every hour of run time)
1. Remove the clip from the air filter and remove from the metal
hanger. Remove the air filter assembly from the carburetor bore by
pulling the entire filter assembly firmly to the side to release it. Do
not pull straight up.
2. Remove the pre-filter element.
3. Clean the pre-filter element by thoroughly washing the foam
element in hot soapy water (dishwashing detergent works well).
Repeat twice.

4. Thoroughly dry the pre-filter
element with a clean towel.
5. Oil the foam element with air
filter oil. Use Traxxas filter oil
(part# 5263) or a high-quality,
special-purpose foam-filter oil
such as that used for off-road
motorcycle and ATV engines.
This type of filter oil is available at motorcycle pro-shops. Apply a
total of 24 drops of Traxxas air filter oil, evenly distributed between
the top, bottom, and sides of the filter element. Squeeze the filter
element repeatedly to help spread the oil throughout. The filter
element should be evenly colored by the oil. Even color indicates
that the oil is spread evenly. Do not squeeze out excess oil. Note: Do
not use the air filter oil for anything other than the air filter. It is not
meant to be a lubricant.
6. Reassemble the filter and install it on the engine. Make sure the
rubber filter neck fits securely on the carb with no gaps or air leaks.
Primary Filter Cleaning Instructions (every 3 - 4 hours of run time)
1. Remove the clip from the air filter and remove from the metal hanger.
Remove the air filter assembly from the carburetor bore by pulling
the entire filter assembly firmly to the side to release it. Do not pull
straight up.

2. Remove the pre-filter element.
3. Remove the 3x6mm screw in the end of the filter housing. Remove
the front housing and the primary filter element.
4. Clean the filter parts by thoroughly washing in hot soapy water
(dishwashing detergent works well). Repeat twice for the foam
filter elements.
5. Thoroughly dry the foam pre-filter and primary filter elements with a
clean towel. Dry the remaining filter parts.
6. Oil the foam pre-filter with 24 drops of air filter oil and the primary
filter element with 30 drops of air filter oil.
7. Reassemble the filter and install it on the engine. Make sure the
rubber filter neck fits securely on the carb with no gaps or air leaks.
