VASHON AIRCRAFT RANGER R7 MAINTENANCE MANUAL
GENERAL
The induction air for the engine enters through a filter which protrudes through the lower
cowling. Alternatively, the pilot may use the carburetor heat control, which operates a butterfly
valve that allow heated, unfiltered air to feed into the carburetor. The carburetor heat control is
located on the instrument panel and is discuss further in Section 5.7.19 and 5.7.13.
CAUTION
Ground operations with the carburetor heat control in the hot position
must be limited because it allows air to bypass the filter.
Should the air filter become obstructed, the carburetor heat control provides an alternate means
of supplying the engine with air for the induction system.
