PRIMARY MAINTENANCE
The engine must gulp
about 12,000 gallons
of air for every gallon
of fuel used. Because
of its working
environment, the air
available to your
Snapper engine is
heavily saturated with
airborne dirt particles.
As the dirt particles are stopped, they build up
and begin to clog the outside of the air filter.
This reduces the amount of air available to the
engine and causes an over-rich fuel mixture
which results in the following adverse effects:
An improperly serviced, dirt
clogged air cleaner will:
1.
Increase fuel
consumption.
2.
Cause power loss.
3.
Result in hard
starting.
4.
Create smoke from
unburned fuel.
5.
Produce carbon
build-up internally.
6.
Foul spark plug
electrodes.
7.
Score cylinder walls.
8.
Burn valves.
9.
Wear out the engine
pre-maturely.
10.
COST YOU MONEY!
Knowing the dirt will
quickly ruin an engine,
manufacturers equip their
engine with extremely
efficient air cleaners to
filter out the harmful dirt.
Damage caused by a poorly serviced air
cleaner is not covered under the engine
warranties. So, save yourself unnecessary
expenses and undue aggravation by keeping
the air cleaner properly serviced at the
intervals specified in the engine owner’s
manual.
It doesn’t take long to service an air cleaner.
Follow the specific instructions in the engine
owner’s manual for the type filter used.
Prevent dirt from falling into the carburetor
intake when servicing your air cleaner. Make
sure components are installed in correct
sequence after servicing to prevent unfiltered
air from entering the engine. Some servicing
hints on several common types are:
