ENGINE TECHNICAL INFORMATION
This is a single cylinder, L-head, air cooled engine. It is a low emissions engine.
In the State of California, Model Series 120000 engines are certified by the California Air Resources Board to meet emissions standards for 125 hours. Such certification does not grant the purchaser, owner or operator of this engine any additional warranties with respect to the performance or operational life of this engine. The engine is warranted solely according to the product and emissions warranties stated elsewhere in this manual.
Power Ratings
The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002 05). Given both the wide array of products on which our engines are placed, and the variety of environmental issues applicable to operating the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a piece of power equipment (actual “on-site” power). This difference is due to a variety of factors including, but not limited to, the following; differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, maximum governed engine speed, individual engine to engine variability, design of the particular piece of power equipment, the manner in which the engine is operated, engine run-in to reduce friction and clean out of combustion chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match the values derived using the foregoing codes.

GENERAL RECOMMENDATIONS
Regular maintenance will improve the performance and extend the life of the pressure washer. See any authorized Sears dealer for service.
The pressure washer warranty does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain pressure washer as instructed in this manual including proper storage as detailed in “Storage” on pages 17-18.
Some adjustments will need to be made periodically to properly maintain your pressure washer.
All service and adjustments should be made at least once each season. Follow the requirements in the "Maintenance Schedule” chart above.
NOTE: Once a year you should clean or replace the spark plug and replace the air filter. A new spark plug and clean air filter assure proper fuel-air mixture and help your engine run better and last longer.
If equipped with inflatable tires, keep the air pressure at the value marked on the tire or within 15 and 40 psi.
EMISSION CONTROL
Maintenance, replacement or repair of the emission control devices and systems may be performed by any non-road engine repair establishment or individual.

Purge Pump of Air and Contaminants
•Use a vacuum cleaner to pick up loose dirt and debris. To remove air from the pump, follow these steps;
•Use low pressure air (not to exceed 25 psi) to blow away dirt. Inspect cooling air slots and openings on the pressure washer. These openings must be kept dean and unobstructed.
Check and Clean Inlet Screen
Examine garden hose inlet screen. Clean if it is clogged or replace if it is torn.
Check High Pressure Hose
High pressure hoses can develop leaks from wear, kinking, or abuse. Inspect hose before each use. Check for cuts, leaks, abrasions, bulging of cover, or damage or movement of couplings. If any of these conditions exist, replace hose immediately.
^ WARNING
The high pressure stream of water that this equipment produces can pierce skin and its underlying tissues, leading to seri ' '
and possible amputation.
NEVER repair high pressure hose. Replace it.
Replacement hose rating MUST exceed maximum pressure rating of unit.
Check Gun and Nozzle Extension
Examine hose connection to gun and make sure it is secure. Test trigger by pressing it and making sure it springs back into place when you release it. Engage trigger lock and test trigger. You should not be able to press trigger. Replace gun immediately if it fails any of these tests.
