The Air Filter; Filling The Fuel Tank; Air Filter Cleaning Instructions - Traxxas Revo 3.3 5309 Owner's Manual

Filling the Fuel Tank

Use a fuel dispensing bottle (Traxxas Top Fueler, part
#5001) to put fuel into Revo'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, pull up on the
fuel cap handle, insert the tip of the
fuel bottle, and squeeze to
dispense the fuel.

The Air Filter

The TRX 3.3 Racing Engine air filter
is specifically designed to deliver
maximum performance while
protecting your engine from dust and dirt. 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 TRX 3.3 Racing Engine air filter assembly consists of 3 pieces:
1. A rubber filter base.
2. A plastic housing consisting of a permanently
assembled mesh cap and body.
3. An oiled foam element.
You must clean the filter after every hour of run time, even if the filter
looks clean. This includes 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.

Air Filter Cleaning Instructions

1. Remove the air filter from the carburetor
bore by pulling the entire filter assembly
firmly to the side to release it. Do not pull
straight up.
2. Disassemble the filter. Pull the rubber air
filter neck out of the filter body. With the
base removed, the foam element is visible
in the bottom of the filter body. Pull out the foam element.
3. Clean the filter parts by thoroughly washing all three pieces of the filter
assembly in hot soapy water (dishwashing detergent works well).
Repeat twice.
4. Thoroughly dry the parts with a clean towel or compressed air.
Remember to wear your safety glasses when working with
compressed air.
5. Oil the foam element with foam filter oil. Use the supplied Traxxas filter
oil (part# 5263) or a high-quality, special-purpose foam filter oil like
what is used for off-road motorcycle and ATV engines.This type of filter
oil is available at motorcycle pro-shops. Apply 30 drops of the Traxxas
filter oil evenly to the top, bottom and sides of the filter element (30
total drops divided among the 3 surfaces). 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
distributed 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, making sure
the rubber filter neck fits securely on the carburetor with no gaps
or air leaks.
