CHEROKEE CRUISER
DRAINING FUEL VALVES AND LINES
The fuel system should be drained daily prior to first flight and after refueling to
avoid the accumulation of water or sediment. Each fuel tank is equipped with an individual
quick drain located at the lower inboard rear corner of the tank. The fuel strainer and a
quick drain valve are located on the lower left corner of the fire wall. It is important that
the fuel system be drained in the following manner:
a.
Open the quick drain valve for a few seconds with the fuel selector valve on one
tank. Then change the fuel selector valve to the opposite tank and repeat the
procedure. Allow enough fuel to flow out to clear the fuel line as well as the fuel
strainer.
b.
Collect the fuel in the container provided for that purpose, and examine the contents
for water and sediment. Dispose of contents.
c.
When fuel is flowing clearly, close drain securely, making sure that there is no
leakage.
CAUTION
When draining any amount of fuel, care should be taken to
ensure that no fire hazard exists before starting engine
DRAINING FUEL SYSTEM
The bulk of the fuel may be drained from the system by opening valve at the
inboard end of each fuel tank. Push up on the arms of the drain valve and turn
counterclockwise to hold the drain open. The remaining fuel in the system may be drained
through the filter bowl. Any individual tank may be drained by closing the selector valve
and then draining the desired tank.
CAUTION
Whenever the fuel system is completely drained and fuel is re-
plenished it will be necessary to run the engine for a minimum of 3
minutes at 1000 RPM on each tank to insure no air exists in the fuel
supply lines.
TIRE INFLATION
For maximum service from the Cherokee tires, inflate all three to the proper pressure of 24
pounds. If necessary, interchange the tires on the main wheels to produce even wear. All wheels
and tires are balanced before original installation, and the relationship of tire, tube and
wheel should be maintained if possible. Out of balance wheels can cause extreme vibration on
takeoff. In the installation of new components, it may be necessary to rebalance the wheels with
the tire mounted.
BATTERY SERVICE
The 12-volt battery is located under the baggage compartment floor. The battery box has a
plastic drain tube which should be opened occasionally to drain off any accumulation of liquid.
Check the battery for proper fluid level. (Do not fill above the baffle plates.) Use only water -
no acid. A hydrometer check should be performed to determine the percent of charge in the
battery.
