Actual use and your experience will determine the frequency of required maintenance. * All recommendations to replace are based on the finding of damage or wear during inspection. (1) Replacement will be required for Commercial use after 600 hours. For Consumer use, cleaning every 6 months is required. (2) Apply 1~2 pumps of ECHO® LUBETM every 10 hours. 20 20 AIR FILTER Level 1. Tools required: 25 or 50 mm (1 or 2 in.) medium bristle paint brush Parts required: 90008 REPOWERTM AIR & FUEL FILTER KIT 1. Close choke (Cold Start Position).

Clean and inspect the element for damage. If element is fuel soaked and very dirty, replace. 3. If element can be cleaned and reused, be certain it: -still fits the cavity in the air cleaner cover. -is installed with the original side out. NOTE Carburetor adjustment may be needed after air filter cleaning/ replacement. FUEL FILTER Level 1. Tools required: 203-254 mm ( 8-10 in.) length of wire with one end bent into a hook. Clean rag, funnel, and an approved fuel container Parts required: 90008 REPOWERTM AIR & FUEL FILTER KIT WARNING DANGER Fuel isVERY flammable. Use extreme care when mixing, storing or handling. 1.

Tighten spark plug to 145-155 kg/cm (125-135 in. lb.). COOLING SYSTEM CLEANING Level 2. Tools required: 3 mm Allen wrench, 4 mm Allen wrench, Pointed Wood Stick, Cross head Screwdriver Parts required: None if you are careful. IMPORTANT To maintain proper engine operating temperatures, cooling air must pass freely through the cylinder fin area. This flow of air carries combustion heat away from the engine. Overheating and engine seizure can occur when: • Air intakes in the crankcase are blocked, preventing cooling air from reaching the cylinder. • Dust and grass build up on the outside of the cylinder. This build up insulates the engine and prevents the heat from leaving. Removal of crankcase cooling passage blockages or cleaning of cooling fins is considered “Normal Maintenance”. Any failure attributed to lack of maintenance is not warranted. 22 22 1. Remove starter and disconnect the throttle cable end from the carburetor. 2. Remove the two screws that retain the engine cover. Lift the engine cover (A) from the engine and lay aside. NOTE The throttle cable remains assembled to the engine cover (A) and the spark plug lead and grommet remain installed. IMPORTANT DO NOT use a metal scraper to remove dirt from the cylinder fins. 3. Use the wooden stick or brush to remove dirt from the cylinder fins. 4. Remove grass and leaves from the starter air intake grid. NOTE When installing the engine cover (A), be certain the tab of the metal deflector shield is in the slot of the cover. A EXHAUST SYSTEM Spark Arrestor Screen Level 2.

NOTE Every unit is run at the factory and the carburetor is set in compliance with EPA Phase 1 and California Emission Regulations. In addition, the carburetor is equipped with HI (A) and LO (B) needle adjustment limiters that prevent settings outside acceptable limits. 1. Before adjusting the carburetor, clean or replace the air filter and spark arrester screen. 2. Start engine and run for several minutes to reach operating temperature. 3. Stop engine. Turn HI (A) speed needle CCW (counter clockwise) to stop. Turn LO (B) speed needle midway between full CCW and CW (clockwise) stops. 4. Id...
