Air CoolingSystem
Over time debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified Sears
service dealer clean the cooling system per recommended
intervals (see MaintenanceSchedule). Equally important is to
keep top of engine free from debris. See CleanDebris.
Keep areas within heavy line clear of debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see an authorized
service dealer.
,A CAUTION Excessively high operating speeds could
result in minor injury.
Excessively low speeds impose a heavy load.
• DO NOTtamper with governor spring, links or other parts to
increase engine speed. Pressure washer supplies correct rated
pressure and flow when running at governed speed.
• DO NOTmodify pressure washer in any way.
