Page: 24 / 59

Maintenance, replacement or repair of the emission control devices and systems may be
performed by any nonroad engine repair establishment or individual.
In the carburetor, fuel is mixed with air. When the engine is tested at the factory, the
carburetor is pre-set.
SPEED ADJUSTMENT
When the Mini-Lite
TM
is tested at the factory, the engine working speed is basically
adjusted. The working speed for the engine is 8500 rpm (+/- 250 rpm). A further
adjustment may be required, according to climate or altitude existing at the place to work
with the machine.
To adjust the engine speed remove the plastic
air cleaner cover from the engine, loose the
adjuster screw; to increase the speed unscrew
the adjuster screw and rotate the plastic plate
clockwise, to decrease the speed rotate the
plastic plate counter clockwise, then tight down
the screw to hold the position. Check the speed
with a tachometer after 5 or 7 minutes of
operation, readjust if required. Reinstall the
plastic air cleaner cover.
AIR FILTER
The air filter must be cleaned periodically from dust and dirt in order to avoid:
Carburetor malfunctions, Starting problems, Engine power reductions, Unnecessary wear
on the engine parts and/or abnormal fuel consumption.
Clean the air filter daily or more often if working in
exceptionally dusty areas.
To clean the air filter, remove the air filter cover
and the filter (1) as shown in the right diagram.
Rinse the filter in warm soapsuds. Check that the
filter is dry before reassembly. An air filter that has
been used for some time cannot be cleaned
completely. Therefore, it must regularly be
replaced with a new one. A damaged filter must
be replaced.
